"Master Lin, which casting furnace is it from..."
"Casting Furnace Eight, Minister."
"Oh, yes, yes, No. 8, haha, look at my memory..."
"..."
"Master Lin, why did you come to the workshop so early today? Have you had breakfast? How about we go eat something first and then come back..."
"I've eaten, Minister."
"Okay...hehe...just eat it..."
"..."
The conversation without any nutrition continued until the casting area stopped. Minister Bonegn finally let go and quietly wiped his sweat...
The magic masters were naturally following behind the two of them, but after all, they were all elderly people, and their strength had already been established. They rarely spent time practicing on weekdays, and their physical strength and energy were somewhat unable to keep up. At this time, I finally relaxed a little, and the tiredness came back again, and I couldn't help but yawn a few times.
However, no one is willing to leave. In the Rose Point branch, in front of this "Master Lin", they are the most loyal fans like all the masters of magic who are still sleeping!
In the large-scale War Court Legion, there are naturally many magic masters with profound strength and transcendent status, but their "fields" are basically in the master-level custom-made magic tools, which are individually designed according to the characteristics of each strong person. Individual manufacturing cannot form a production line, so most of the "workstations" of the magic masters are in their own laboratories on the main continent. After all, even if there are ten or eight sets of master-level customized magic tools, it will not be enough. It will be the size of a container, and the military space array is enough to complete the transmission.
Therefore, in the magic crafting workshop of the Ministry of Military Resources, these magic crafting masters are the absolute main force, with eight legions and five battle camps, more than a dozen types of mass-produced standard magic tools, and millions of master cultivators. Human body enchantment, the main work of the magic masters can only be placed on the intermediate formations, and they rarely have the energy to focus on other things.
However, in the past year, except for the first one or two months, the magic masters of the Rose Point branch have become more and more leisurely, and have even begun to do some basic work such as formation material preparation, magic equipment quality inspection, etc.
This is not to say that the magic masters have completely given up their main business, but everyone's workload is indeed getting less and less.
There is no other way, who can be like "Master Lin" who can come up with a pen without any breaking techniques! But the success rate can be as terrifying as 100%? !
Who else can achieve double superposition effects on any intermediate formation? ! Those intermediate formations are a collection of dozens of sub-formations! It is a formation system that is connected layer by layer and interlocked!
In the science of magic creation, this is not a god-like skill! What is it? !
Don't listen to such experts. They have lived for most of their lives and have never dared to think about it!
Of course, the decision to give up one's own "mark" from now on comes from the heart, and no master of magic creation feels forced!
"Master Lin" probably doesn't know about it himself. Even if he knows, he should be as usual and not be moved at all by such trivial matters. As for the round "white hat", it is the "suggestion" of Minister Boyne. , saying that this is an indispensable "process" before the finished magic tool is finished, otherwise it would not be possible at all...
Regarding this "suggestion", all the magic masters were sincerely convinced, saying that the minister was indeed an "old ginger", and indeed more "spicy"...
There is naturally no "white hat" on Trial Production No. 1, which is indeed a pity in the hearts of the masters. Fortunately, all recent standard magic tools have begun to have this mark attached to them, and all formations are also "Lin". "Master" does it all.
There are ten casting furnaces in the Ross Point branch. Each furnace produces an average of about a hundred pieces per batch. After the formations are carved separately, they are simply assembled. After inspection, they are the real finished products.
A person like "Master Lin" naturally doesn't care about "this little" workload. He is already responsible for nearly 70% of the formation tasks of the entire branch!
However, this incident made all the magic masters even more worried!
——Usually, they can share some work for "Master Lin", but now they can't do it well for anyone! Even excluding the double superposition, the effect of their formations is several times worse than that of "Master Lin"! This is true even if Minister Bonne, who is the most experienced in writing skills, goes into battle in person!
But this is not to blame the masters, the castings produced recently are really weird!
It's as if these castings have grown "textures" that are innately prepared for formations!
As long as the backbone of the formation is engraved on these "lines", even if the entire formation is distorted, the effect will be extraordinary!
But these "grains" are different for each casting! Only "Master Lin" can "see"...
However, "Master Lin" has never explained this unheard-of "texture method" in detail, and his attitude is completely different from when he trial-produced No. 1, as if he has any scruples...
According to "Master Lin", this kind of weirdness is also one of his "experiments" and is "a manifestation of the immaturity of the product." After the experiment is successful, these "textures" will basically disappear, and the formation drawing will also disappear. No more trouble...
This made the magic masters even more uncomfortable, but they couldn't ask too much. However, "Master Lin" finally changed the casting production process a while ago. It stands to reason that the experiment has produced results, although they can't tell it from the new version of the document. What, it’s just more detailed and strict regulations on temperature, time, and concentration of environmental structures, but today’s batch of castings is the first batch produced according to the latest technology!
Several magic masters thought of this in unison, and their fatigue disappeared in an instant. They rushed to the No. 8 casting furnace and squeezed the operating technicians in several key seats behind them.
The two veterans "Lao Bei" and "Lao Mo" are naturally paying attention to them. The interior space of the workshop is generally circular, which facilitates the pouring of molten steel from the furnace into the casting furnace through the conveyor channel. The location of the No. 8 casting furnace is also It's closer to the door than Trial Production No. 1.
In a mature magic workshop, in addition to the element furnace, the casting furnace is the most common production equipment.
Its function is to receive the smelted molten steel, inject it into different mold boxes according to different needs, and directly produce various types of castings of different shapes after quenching, tempering and other main processes.
If the molten steel production exceeds demand, it can also be cast into steel billets of general specifications, which is very convenient for storage and sales.
As for the military magic workshop, almost all of the equipment used is not the most advanced. Although it is good enough in terms of the "continuous no-alarm time" indicator, it cannot be as abnormal as the trial production No. 1. It must be able to satisfy There are at least ten thousand people's needs for magic equipment replacement, repair, etc. In addition to stability and durability, the "mean repair time of failures" and "mean maintenance time" are also critical.
This is the case for these ten casting furnaces. They still adopt the traditional "separate cabin structure". From front to back, there are quenching cabin, forging cabin, tempering cabin, shaping cabin, cooling cabin, grinding cabin and resting cabin. Like ten huge metal giant silkworms, lying on the ground.
Such a structure can inherently decompose the casting process. Although the degree of automation is not high and each cabin requires dedicated personnel to operate, the advantage is that the cabins are independent and easy to maintain. If there is a fault, the entire cabin can be directly replaced to carry out parallel operations. Repair will not have much impact on casting production, and this structure can also realize simple assembly line operations. Just replace different mold boxes, and the overall performance is optimal.
This form of casting furnace has been in shape for hundreds of years and is one of the most mature magic equipment. The design drawings have been circulated for a long time, and even the most ordinary technicians are familiar with it.
"Master Lin" opened the work log and checked it as usual, and then nodded calmly. The operations of the several masters were a little unfamiliar, but there were no mistakes. The "quiet cabin" of the No. 8 casting furnace was quickly opened. Hundreds of casting boxes that have long since returned to room temperature are placed neatly.
This batch of castings was part of the heavy armor worn by the "Shield Puppet Battalion". Minister Bonne stepped forward quickly, randomly selected one of them to open, and carefully took out the silver-white castings without the need for "Master Lin" After ordering it, he quickly put it into the inspection equipment next to it and started the operation. In the past few decades, Minister Boyne has completed such inspection work countless times.
But he soon shouted, and everyone in the workshop heard it clearly!
"Impact strength...exceeds 80 kilojoules! Class A!
"Flexion and extension toughness...over 400 MPa! Grade A!
"Forging hardness...130! 140! 150! Oh my god! 168 standard units! S level!"
The old man grasped the "bird's nest" on his head, as excited as a child!
"Master Lin! This is the best casting produced by our branch!"
The whole workshop was boiling instantly! Applause and whistles rose to the sky! Even the busy technicians shouted excitedly! The two veterans not far away drew out their swords and slapped their breastplates hard!
Of course the veterans don't understand those awkward terms and numbers, but even they know that triple "A" grade castings are of extremely good quality! In the past, even the most experienced and cooperative team of technicians might not be able to produce one out of ten furnaces!
That is to say, during the more than a month of continuous work on the trial production No. 1, after "Master Lin" finally had time to pay attention to the casting area, the quality of the castings in the Ross Point branch began to rise rapidly, and the triple "A" production rate also became It’s as simple as eating and drinking!
Now we finally produce a better product that goes beyond the triple "A" level! This is the glory of the entire Ross Point Division! "Master Lin" is truly worthy of being "Master Lin"!
"Master Lin's" expression is still as plain as water, and no one can see what he is thinking. However, regarding Minister Bohnne's proposal to promote the latest version of "Casting Production Technology" to more than a dozen other branches, "Lin Master" was silent.
Under the watchful eyes of Minister Bonne and all the masters, "Master Lin" walked directly to the "quiet cabin", took another piece and put it in his hand, silently studying it...
The castings that have been randomly inspected before will naturally be scrapped. Only in this way can the extreme indicators of the castings be tested. However, the performance difference between castings in the same furnace will not exceed one percent. This is a conclusion that has been verified countless times, "Master Lin" It should be very clear!
Minister Bonne stepped forward quickly, and felt a sudden shock in his heart. He saw two flashes of crystal white color flowing in the eyes of "Master Lin". Although it was as light as an illusion, it was so eye-catching at this time!
Of all the people present, no one understands the meaning better than Minister Boyne! In the past year, this kind of "illusion" and the "loss" that followed were the most he had ever experienced!
Sure enough, "Master Lin" quickly turned around, glanced at the No. 8 casting furnace operating technicians who were still cheering, and asked lightly:
"Who operates the tempering chamber?"
The people in the workshop fell silent instantly, and for a while only the magic equipment was operating harshly. Under the strange eyes of the crowd, a middle-aged technician walked out of the crowd with his head lowered, his hands tightly pressed to the sides of his pants. As if the child was about to be punished, he whispered:
"Master Lin...it's me..."
"Is the ambient formation always on?"
"It's normally open! According to the new version of the process requirements, I switched the cabin after running it for an hour in advance..."
"Is there any warning during transfer?"
"Absolutely not! I have been keeping an eye on the concentration of 'oxygen disulfide', 'one carbon dioxide' concentration, 'one oxygen dihydrogen' concentration, and the concentration of inert gaseous components! The tightness of the cabin There’s nothing unusual about it!”
"Um."
"Master Lin" nodded. Under the snow-white "hat", the small half of his face that was as delicate as a sculpture was also like a sculpture, without any fluctuations. He said softly as if talking to himself:
"That's the tempering temperature."
When the middle-aged technician heard this, he couldn't help but said:
"Master Lin... the temperature of the tempering chamber has always been stable at 816 degrees, and the temperature fluctuation has never exceeded the standard. I have read the latest version of the production process carefully several times, and there is absolutely no error..."
Everyone's eyes were still so strange, and they didn't change at all because of the middle-aged technician's words. They just carefully concealed it to avoid piercing the worker...
Because similar scenes have happened many times in the past year, the people named by "Master Lin" must have made mistakes somewhere. In the end, without exception, they all ended up bowing their heads and admitting their mistakes!
Both parties involved and bystanders were looking at "Master Lin", waiting for that mechanically calm voice to make a "judgment" or give a "conclusive conclusion", and then, as usual, everyone would be convinced...
However, "Master Lin" just said:
"knew."
These three words are still as plain as water, but they are heavier than the pressure of hundreds of megapascals in the forging chamber! The middle-aged technician lowered his head and his face turned even redder!
Everyone sighed in their hearts. In the past year, many of them had appeared in the position of the middle-aged technician, standing in front of "Master Lin". They knew very well that the middle-aged technician was extremely confused at this time. But I feel extremely frightened and helpless! There is also the huge pressure that seems calm but can drive anyone crazy!
"Master Lin" glanced at the tempering cabin for a few times, then glanced at the technicians again and asked:
"Who was responsible for the latest maintenance of No. 8 casting furnace?"
There were more than a dozen technicians in the crowd who looked solemn for a moment. They looked at each other, and an older technician came out and whispered:
"Master Lin, it's me..."
"When was it maintained?"
"Six days ago..."
"Have you seen the new version of the production process?"
"seen it already……"
"Why is the heat transfer ring between the forging chamber and the tempering chamber not replaced?"
The elderly technician was startled and turned his head to look behind him. He saw several technicians lowering their heads immediately. They did not dare to speak, but they walked out of the crowd honestly and stood in a neat row...
"Master Lin" looked at them quietly, and everyone's eyes were cast on them. These technicians were all in their thirties and forties, and they had all worked in this magic workshop for many years. Among them, All of them are experienced veterans and have never been disappointed in the maintenance of casting furnaces. How could there be such a big mistake...
After a few extremely long seconds, one of them finally raised his head slightly, looked at the toes of "Master Lin", and said:
"Master Lin... the new version of the technology requires the width of the thermal ring to be increased from 20 cm to 40 cm... We know that... we have also changed the thermal ring..."
"oh?"
"...It can be considered...changed...but..."
"Just what?"
"...It's just that the original heat-conducting ring is stuck...I can't get it out...and the spare parts in the tempering chamber haven't been repaired yet...so..."
"So you just added a thermal ring, right?"
"……Yes, it is……"
The crowd couldn't help but chatter. In the minds of all technicians who know the maintenance knowledge of casting furnaces, such operations are normal. Many of them have had similar experiences and operations in the past, and it should not have any impact on the quality of the final product. …
The elderly technician had the same idea. He looked at "Master Lin" "bravely", with expectation hidden in his eyes, and asked carefully:
"...Master Lin...this matter...should have nothing to do with us..."
Just listen to "Master Lin" calmly ask:
“What is the material of the thermal ring?”
"Master Hui Lin... is brass..."
“What is the coefficient of thermal expansion of brass?”
"About 15 microns per degree Celsius..."
"The average temperature of the tempering chamber is 816, how much is the deformation of the first heat conduction ring?"
"...approximately...12 millimeters..."
"Will the surface deformation of the thermal ring be uniform?"
"……Won't……"
"How do the two thermal rings come into contact?"
"...It's...it's a groove spring..."
"Why not use fixed clamps?"
"...This...Master Lin...the space at the hatch transition is narrow...it's really difficult to operate..."
"It's not that it's difficult to operate, but it's not that it can't be operated, right?"
"……Yes, it is……"
The elderly technician struggled to say these words, his face was covered with sweat, and it was as hot as if he was in a steamer. Then he heard "Master Lin" calmly say:
"During the transfer of castings, the forging tank and the tempering tank are connected. In order to ensure the gas concentration in the tempering tank, the ambient atmosphere array method will significantly increase the emission of gaseous structures, and the temperature near the hatch will be affected, so The new version of the process stipulates that the average temperature of the tempering chamber must reach 816 degrees to ensure that the temperature during transfer is not lower than the threshold of 800 degrees. Now that there is an additional deformation factor, the temperature of the second heat transfer ring will be insufficient. A rough estimate, Although the temperature of the second thermal ring body exceeds 800 degrees, the temperature near the casting is only about 795 degrees."
"...but...but..." The elderly technician stammered for a long time, and finally asked the doubts of everyone present:
"But the second thermal ring is only 20 centimeters wide... the time for the casting to pass through it will not exceed 3 seconds at most..."
"Yes."
"Master Lin" nodded and said:
"It's just these 3 seconds."
The discussion in the workshop became louder and louder. None of the technicians present understood what impact these short three seconds could have. In the countless experiences accumulated over the past countless years, such trivial details can definitely make a difference. can be ignored! But why is "Master Lin" so harsh?
Even a little bit picky...
But no one knew how to ask tactfully enough. Everyone's respect for this too young but too extraordinary magic master was definitely from the bottom of their hearts!
However, in the face of such extraordinary "peace", any slightly reckless words or deeds must be repeated countless times in the mind!
Whether it comes from others or from yourself, there is heavy pressure everywhere...
However, "Master Lin" did not speak again. He walked directly to the main console of the No. 8 casting furnace, raised his hand and pressed the "stop" button!
At the critical moment, Minister Bornne was prepared. The old man had already felt that something was wrong, so he rushed forward like a flying bird, and he finally caught the white palm in time!
If anyone else dared to do this, even the head of the legion, the old man would have to point his nose and curse a few words before he stopped. But in front of "Master Lin", he had no choice but to ask:
"...Master Lin...you...what are you going to do..."
"Minister, this batch of castings is unqualified, and all the semi-finished products in the No. 8 casting furnace must be recast."
"...unqualified? This is grade three 'A' or above! You...you said they are unqualified?!"
"Yes, Minister, based on recent experimental data calculations, if the new version of the process can be produced strictly, the probability of the casting index reaching double 'S' grade is about 75%, and the probability of triple 'S' grade is about 25%. After the operation is proficient, The probability of triple 'S' production will increase slightly. Taking into account the operating capabilities of the No. 8 casting furnace technician team and the various stage data of this batch of castings, the triple 'S' rate will stabilize at around 30%."
"...Wha...what? Three...'S' level? And a 30% chance?!"
"Yes, Minister. Moreover, the three 'S' grade castings will greatly eliminate the internal texture, and the carving formation will basically not have the previous problems."
"..."
The whole workshop exploded with a bang!
——That's three "S" levels! A difference of one word can make a huge difference in the quality of castings!
According to rumors, only "alloys" that are mixed with one or several rare minerals and smelted according to the proportions and special methods of some profound secret recipes can reach the three "S" level!
It’s just that the rare minerals required for “alloy” are in extremely short supply! Only master-level magic tools have such high requirements for castings of that level, and most of them will only be reflected in some core castings!
——Master-level castings are just steel. To put it bluntly, they are high-purity iron! "Master Lin" couldn't be joking...
Minister Bornne almost asked the question, but finally swallowed it back, his face turned red from holding it in!
"...Master Lin... let's finish this batch before we finish it... let's try the new version of the craft in the next batch..."
"Minister, why? It takes time to replace the thermal ring, remove the waste materials in the furnace, and cool down."
"...Master Lin...how can it be scrap...These castings are at least three 'A' level after all...It would be a pity to recast them..."
"Minister, these batches are unqualified products. Double 'S' and triple 'S' grades are more excellent. According to calculations, double 'S' grade castings can also be carved with the array method according to the original method, and the output loss is less than 3dB compared to the 'texture method' , it is acceptable and can meet the recent requests made by you and other masters."
"... This... this is not a problem with the formation... Of course it would be great to be able to carve the formation like before... We old guys also have something to do... Uh... I mean... the quality of this batch of castings is... After all, it’s extraordinary...Can’t you be accommodating..."
"Minister, according to the new version of the technology, these castings are unqualified."
"...Master Lin...why is he not up to standard...the tens of thousands of soldiers in our military station...the magic equipment they carry is at least triple 'A' level...aren't they all up to standard? Do they have to be recast in the furnace?" …”
"Yes, Minister, once the new version of the process is verified, large-scale replacement can be carried out sequentially."
"...I...I don't agree! I don't accept your statement!"
"Minister, why?"
"...If you disagree, you disagree! Unless you explain clearly what is going on with these castings..."
The old man gritted his teeth and turned his head sharply. Of course, he was still holding on to "Master Lin"'s hand, like a child who had been wronged...
A group of magic masters gathered around one after another, and a master with clearer eyebrows said in a low voice:
"Master Lin... please don't be angry... We absolutely believe what you say... The next batch of castings will definitely have three 'S' grades... But why did just 3 seconds have such a big impact... There is the previous 'grain method'... How does it relate to the grade of castings... Can you tell us about it... We have asked you countless times... but you are always silent... We are a bunch of people I dream about these things at night...it's really painful...I think the minister means the same thing..."
In fact, Minister Bornne had begun to regret it a long time ago. At this time, he hurriedly borrowed the donkey from Poxia and said repeatedly:
"That's right! Master Lin...I am not an unreasonable person..."
Everyone in the workshop listened with their ears pricked up, and the masters were also spinning countless words of persuasion in their hearts in order to deal with the unshakable "calm", even though they had already been struck by this "calm". I have withdrawn countless times...
However, today's "Master Lin" was much more happy. He was silent for a moment and then nodded and withdrew his palm.
He still picked up a charcoal pencil and drew two patterns on the heat-resistant glass of the tempering chamber. They were both the simplest "cube" diagrams with eight vertices and twelve line segments as the basic skeleton.
There is only one point on each of the six faces of the first "cube", located in the center of each plane, but there is only one more point on the second picture, at the very center of the entire "cube".
Just listen to "Master Lin" calmly preach:
"Minister, masters, the reason why steel castings are harder than ordinary iron castings is because of the purity of the substance 'iron'.
"Whether it is an element melting furnace or a casting furnace, its function is to strive to increase the content of 'iron', and under high-temperature liquefaction conditions, create a suitable environmental atmosphere through various formation methods, and carry out purification processes such as desulfurization, dephosphorization, and decarburization. .
"When the purity of 'iron' exceeds 98%, it can be called 'steel'.
"The remaining less than 2% of the material is mostly 'carbon', which is the main material in this charcoal pencil.
"According to the knowledge of 'classical origin theory', when the purity of the solid material is high enough, the distribution structure of the internal atoms will be mostly uniform. For steel castings, under ideal conditions, there are two basic structures.
"One is called a 'face-centered cubic structure'. On a basic unit cell composed of eight iron atoms, carbon atoms are distributed in the center of the surface of the six unit cells.
"The other type is called the 'body-centered cubic structure', where the carbon atoms are much sparser and located in the very center of the unit cell.
"The carbon content of the 'face-centered cubic structure' is naturally greater than that of the 'body-centered cubic structure', and its stability is not as good as the latter; within the casting, the unit cell parts with a uniform structure are much stronger than the non-uniform stray parts. , these are two important factors that affect the grade of steel castings.
"Therefore, in order to improve the grade of castings, it is necessary to form a sufficient proportion of 'body-centered cubic structure' inside the castings. According to the external structure of iron atoms in the 'classical origin theory' and combined with the existing production conditions, the overall carbon content of the castings It needs to be controlled within 0.2% to 0.25%.
"Ideally, this 'body-centered cubic structure' will grow into clusters of basically straight lath shapes. As long as the proportion is sufficient, the staggered or broken parts between the laths will be reduced to a minimum. level of tolerance.
"If the body-centered cubic structure has fewer unit cells, there will be many scattered 'textures' inside the casting, which is also the obviously weaker part of the internal structure of the casting. At this time, the ordinary engraving method is naturally inferior to the 'texture method' ', cannot effectively compensate for the weaknesses of the casting itself.
“According to experiments, if we want to meet the above standards, we must strictly control the temperature, time, ambient concentration and other conditions of each link. This is the role of the new casting process.
"The temperature control of the tempering chamber is very important, because the unit cells in the casting grow extremely fast. Even if it is below the 800-degree threshold for only 3 seconds, all laths cannot be formed, but laths and flakes or even Needle-like combination.
“At the same time, as long as 3 seconds, the internal carbon content of the casting will exceed 0.25%. Although the final forging hardness is sufficient, the impact strength and flexural and extension toughness will be greatly deteriorated, and it can only barely reach Grade A. It’s just that according to the new casting process, it cannot be regarded as a qualified product.”
The charcoal was quietly placed back on the table. "Master Lin" looked at everyone and asked lightly:
"Minister, masters, can you stop the machine?"
The ordinary technicians looked at each other in confusion. As junior magicians, they could only understand some literal meanings at most...
However, Minister Bonne was certainly different from the other magic masters, but they all had their brows furrowed. Several higher-level masters unexpectedly closed their eyes in unison, and their vitality loomed, as if they were struggling to suppress it. What are you wearing!
After a long time, the masters returned to normal, but their faces looked sad. Then they held their hands and saluted more respectfully, and silently walked to their work areas...
Minister Boney sighed deeply. As a master of six-star magic, he seemed to be fished out of water, and he was visibly sluggish!
The old man raised his hand weakly, scratched his "bird's nest" reluctantly, and said with a wry smile:
"Master Lin... I listen to you..."
