It took two months for a Mo Dao, and the blacksmiths recruited by Pu Yuan were far less efficient than him in making it.
This efficiency is indeed too low and cannot be promoted.
The reserves before the war were barely adequate, but once they were damaged during the war, they could not be replenished at all.
Weapons made in this way are also very difficult to repair.
"...Why don't you use Bai Steelmaking?" Liu Chan asked with a frown.
Pu Yuan said nothing and silently presented another knife with the same shape.
To be honest, Liu Chan didn't see much difference.
He walked to another wooden stake where he was testing the knife, exhaled and swung the knife with all his strength!
Bang!
The angle is the same, the force is about the same, but the results are very different.
After breaking through only a few layers of leather, the knife broke.
If what happened just now was on the battlefield, I don't know whether it would be possible for both men and horses to be shattered, but it would definitely be no problem for both men and women to be shattered with swords... Of course, it would be my own side that would be shattered.
"Ordinary blades have uneven softness, hardness and toughness. With such a shape and such use, it will easily break..." Pu Yuan said helplessly.
Now Liu Chan understood that in order to achieve the ideal effect of Mo Dao, in addition to the style design, the most important thing is the material.
If the quality of the material used in the blade cannot be improved, anything else is useless.
It would be no problem to make one for the generals, such as the iron spears for myself and Uncle Zhao, as well as Zhangba Snake Spear, Yanyue Sword, etc.
If you want to make one, it will not be difficult if you have the diagram that Liu Chan originally drew.
The difficulty is precisely that this kind of weapon requires large-scale equipment, and it is useless just to have a picture.
Whether it is Tang Dao or Mo Dao, the reason why many later generations of knives are easy to use is only a small part of the reason why they are easy to use. Reasonable design is only a small part. What is more important is the improvement of forging technology.
Liu Chan sighed, he couldn't rush this, he would put the "platform", funds, and R&D environment in place, and the rest would depend on the wisdom of these professionals.
"Speaking of it, Gu actually came here with a few ideas, which may be helpful to you in forging weapons." Liu Chan said, handing the broken knife to the craftsman on the side.
Pu Yuan's brows relaxed, and he changed his frustration just now and said with great interest: "I would like to hear the details."
The last time he discussed blacksmithing with the prince, the prince's whims and diagrams gave him a lot of inspiration.
Although many of the weapons on the map have no actual production significance because of insufficient materials, there are also many designs worth learning and improving for current weapon production.
As soon as I saw these blast furnaces, some thoughts appeared with my gradually clearer memories.
The first is the furnace temperature. Before more advanced chemical technology is turned on, it is impossible to significantly increase the furnace temperature, but it is not completely impossible.
Liu Chan took Pu Yuan to those "ancient blast furnaces".
He pointed to the blast ducts supplying air on both sides of the blast furnace: "If the position of these blast ducts were changed, they would be heated by the residual temperature of the blast furnace before the air is supplied..."
Pu Yuan's eyes lit up: "This can eliminate the impact of cold wind on the furnace temperature and further increase the temperature that can be achieved in the furnace!"
[Pu Yuan favorability +10] (80)
[Pu Yuan's favorability is 80, constitution +5, forging talent +15×2]
As expected, he is a professional, and he gets it right without any hassle.
"I have discovered a large amount of coal deposits in Nanzhong, and a batch has been shipped this time. In the future, coal can be used in the smelting furnace instead of charcoal, which will further reduce the cost."
Although charcoal smelting has lower impurities than coal, now that large coal mines have been discovered, the cost is much higher than coal.
"Thank you, Prince!"
[Pu Yuan favorability +10] (90)
[Pu Yuan's favorability is 90, constitution +5, forging talent +15×2]
Then comes the fried steel. In fact, fried steel uses the stirring of molten iron to cause an oxidation reaction between the carbon inside and the oxygen in the air. It bubbles up to form carbon monoxide and is discharged into the air to achieve the purpose of decarburization.
From high to low carbon content, pig iron, low, medium and high carbon steel and wrought iron will be formed.
During this process, some of the impurities in the molten iron will also be filtered out with the bubbles.
During this process, some of the impurities in the molten iron will also be filtered out with the bubbles.
Of course, people at this time cannot accurately control the carbon content, and they basically fry it until the end. As for what material comes out, it often depends on luck.
The only thing that can be stably produced is pig iron, while wrought iron is more difficult to obtain. It is more of a material with uneven softness and hardness and a lot of impurities. Therefore, it needs to be repeatedly folded and forged to make the carbon evenly distributed and try to remove the impurities.
As for directly tapping the steel, that is even less likely.
Liu Chan then pointed to the pool where the steel was fried: "If we build a cover on this pool, the rising heat can flow back without losing it, and this method can be more complete..."
"That makes it easier to produce wrought iron!" Pu Yuan said excitedly.
[Pu Yuan favorability +10] (100)
[Pu Yuan's favorability is 100, physical fitness +5, forging talent +15×2, and obtains the characteristic "Magical Craftsmanship"]
[Magical Thoughts]: When the blacksmithing knowledge you have mastered reaches the basic requirements and is successfully realized, more advanced blacksmithing knowledge can be learned.
[Has mastered "ordinary blast furnace ironmaking" and "steel frying method", and understood "pig iron sinking method to fill steel"]
Before Liu Chan had time to read these prompts carefully, he felt that his brain became extremely flexible and clear when thinking about things related to smelting and forging.
Wrought iron has a high melting point. Current technology cannot completely melt wrought iron, but it can melt pig iron.
And if the fuel is changed from charcoal to coal, and the steel frying undergoes the improvements just mentioned, a large amount of wrought iron can be obtained more stably and efficiently.
The carbon content of pig iron is too high and it is hard but brittle. Although the carbon content of wrought iron has been reduced, it often drops too low. It contains many oxidized impurities and has good ductility but is too soft.
After both pig iron and wrought iron can be produced in a stable scale, the wrought iron with good softness and ductility can be bent and the pig iron can sink into it.
Then they are put into the furnace together, sealed with mud, and smelted. The oxygen in the wrought iron is used to oxidize the silicon, manganese, and carbon in the slowly oxidized pig iron, causing intense "boiling" to further remove impurities.
And gradually balance the carbon content of the raw and wrought iron, then take it out and hammer it again to further remove impurities until you get steel!
Compared with steelmaking, this method greatly reduces the number of hammering exercises required.
Liu Chan tried his best to express this idea to Pu Yuanyi in the language he used at the time, and he quickly understood.
The more he thought about it, the more feasible it became. Pu Yuan immediately said excitedly: "I will follow the prince's instructions and order someone to modify the furnace!"
His blacksmith soul was on fire and he couldn't wait to try it out.
Liu Chan, who had acquired such characteristics, was also going to stay in Linqiong for a while, and asked Pu Yuan to "make up lessons" to see if he could learn some new blacksmithing knowledge.
Liu Chan, who once dreamed of making thermal weapons but was severely educated by reality, once again activated the "fear of insufficient firepower" in his blood.
Of course, he is now more realistic and knows that it is unrealistic to drastically skip the development stage. This time, he has to upgrade his equipment step by step.
At the same time, Chengdu was informed that coal shipped from Nanzhong would be given priority to Linqiong for production, and firewood would still be used for winter heating material reserves.
Anyway, after Linqiong no longer uses charcoal, the price of firewood will naturally drop and the supply will increase.
Pu Yuan stopped some less urgent work and concentrated on rebuilding the blast furnace.
The two modification methods Liu Chan mentioned were not difficult to do, and there were no technical difficulties. The only difference was an idea, and the modification was completed quickly.
After that, Pu Yuan, who seemed to have been injected with chicken blood, began his first steel-filling test under the witness of Liu Chan.
Blacksmithing master Pu Yuan, coupled with Liu Chan, who had epoch-making insights and talent bonuses, the first batch of steel pouring... failed without any surprise.
Liu Chan looked at the failed work with uneven carburization and an excessive proportion of pig iron, and consoled him: "It doesn't matter, I have no experience the first time, just try again. Failure is success."
Pu Yuan, who originally lowered his head and trembled, raised his head. There was no expected expression of frustration on his face, and there were no tears in his eyes. Instead, they were shining...
"Prince! This method really works! Hahahaha..."
Liu Chan: "..."
It turned out that this kid was shaking with excitement just now, so it was useless to comfort him.
After two failures, the third furnace finally succeeded.
[Have mastered "Pig Iron Falling into Steel Filling" and "Hundred Steel Making", and understood "Steel Wrapping" and "Steel Clamping"]
Liu Chan ignored Pu Yuan, who was roaring excitedly, and silently gave a big thumbs up to the newly added features.
Linqiong County, Yizhou County, began a vigorous arms race against Cao Wei and Sun Wu.
Of course, it is a bit inaccurate to say that there is a competition, because it is conducted unilaterally without the other party's knowledge...
