As he thought this, two teenagers in work clothes emerged from the corner and rushed towards Lin Long and his party. [No pop-up novel website] Lin Hanlong waved his hand and asked them to wait for a while. Then he turned around and entered a corner of his office workshop that was separated by hollow bricks. The inner wall was also laid with soundproof kapok boards. He sometimes stayed overnight in the workshop and did engineering calculations, so he needed a relatively quiet environment.

There were only a few tables, a few cabinets and a row of shelves in the office, filled with documents, papers, strange-shaped glass blocks and mechanical parts. There is also a small door inside that leads to his single dormitory. As a senator, this was one of the few privileges he enjoyed.

Lin Hanlong walked to his desk and opened the cabinet door. Inside the cabinet is a small moisture-proof cabinet with a small Sailboat brand padlock. Lin Hanlong took off a bunch of keys from his belt, picked out one and opened the lock. The humidity here in Lingao is very high in summer, so moisture-proofing is essential. He took out his treasure: a cowhide belt for tools, with a tool hanging on it. A pile of tools and measuring tools brought from the original time and space: a Fluke multimeter, fully functional; a strong flashlight, the original lithium battery is no longer usable. I wonder if Zhonglishi can get a replacement? He took out a calculator from the computer bag he carried with him. It was a ti graphing calculator that he bought at a large price before traveling through time. It had powerful functions. He inserted these things into the corresponding positions on his belt. Finally, he stuffed the entire computer bag into the moisture-proof cabinet and locked the cabinet door.

"Chief Lin! This is today's data." One of the teenagers in work clothes saw him coming out and quickly handed over a large thick notebook. These two teenagers are students. According to the academic system, they must spend a certain amount of time every week to participate in labor in various factories.

Lin Hanlong took it and took a quick look at it: "Let's go take a look at the stove."

The furnace is a newly built optical workpiece annealing furnace. A square black box, covered with refractory bricks. There is a door on the side of the upper part that can be opened, and then the workpiece can be pulled out along the slide rail. The lower part is a stove, with a gas bag connected from outside the workshop, and there are adjustable fire doors and air blast vents. There are several simple pointer instruments on the top of the annealing furnace. They don't even have glass covers. The scale plates under the pointers are hand-painted.

Any glass manufacturing process generally involves the glass annealing process. Lin Hanlong sometimes wonders why the protagonist who burns glass is never injured by glass shards? As a general rule: Rapidly cooled cast glass products have large internal mechanical stresses. Thicker glass blanks are in danger of bursting after slight processing. Therefore, there must be an annealing kiln in the glass factory to anneal the finished glass: reheat the blank to a temperature close to melting, and then let it cool slowly. As for what temperature is appropriate and what the cooling speed is, this is the specific process of the glass factory. Although Xiao Bailang built an annealing kiln and retrieved process manuals from the Great Library when he set up a glass factory, the production conditions in this time and space are different from those in the old time and space, so they cannot be applied across the board. The specific temperature and time were accumulated bit by bit by the veterans and workers of the glass factory.

Now Lin Hanlong and his men have to go through searches to correctly grasp the temperature control data of optical glass products. The two teenagers from the school are human flesh temperature control devices. They must try their best to keep the temperature in the furnace on a predetermined downward curve.

As soon as I got close to the annealing furnace, I felt the heat. Lin Hanlong is used to it. Although the ventilation in the workshop is pretty good, the outside temperature is now 30 degrees. There is no other better way to cool down than mechanical forced ventilation.

Lin Hanlong handed the notebook with recorded data to his apprentice: "Junjie, look at this data."

The apprentice looked at the data and charts carefully, then raised his head: "Master, I think the data this time is very good." The two teenagers next to him were obviously relieved.

Lin Hanlong clicked on a few numbers.

"What do you think of these data?"

The apprentice thought for a while: "I exchanged the thermometer, but the reading is still low, which means there is a problem with the furnace itself."

Lin Hanlong hummed, took out a multimeter, and connected a thermocouple probe. Then insert the probe into the measuring hole on the stove top. He turned the display over to show his apprentice.

"Same on both sides."

Lin Hanlong nodded. "Then we'll do it next time when we renovate."

He turned to the two teenagers on one side: "The fire in the stove can be extinguished and allowed to cool down naturally. Please tell your successor that the stove must be cooled to at least sixty degrees before turning on the stove."

Lin Hanlong then walked to a spherical grinder. Since he made the first hand grinder, the machinery factory has built four new special grinders. The one in front of me is the latest one, with roughly the same structure. The biggest change is that the power is changed to a transmission shaft + belt, and a large number of metal parts are used to replace the less durable wooden parts. In addition, there are many more devices for adjusting various parameters. . At present, the grinder has been torn into eight pieces, and its internal organs have been taken out and placed on the floor. Lin Hanlong crouched down and stared at a bevel gear the size of a watermelon. Several teeth on it had been broken.

"Junjie, go to the office of the Ministry of Science and Technology and call Chief Sun Li and tell him that I'll ask him to come over."

This new equipment broke down less than a week after it was installed and put into use. Yesterday, Lin Hanlong took apart the grinding mill himself to check if it could be solved on the spot. He found that he couldn't solve the fault.

The apprentice agreed and went out. Lin Hanlong stood up and walked towards the other corner of the workshop.

A thin middle-aged man hurriedly came up to him and nodded. "Sir! Ah, chief, hello, chief." This middle-aged indigenous worker who had become a monk would have pounced on Lin Hanlong as soon as he entered the workshop and followed him. After being reprimanded many times by Lin Hanlong, he was finally able to stick to his position. He pointed out several large glass bottles to Lin Hanlong like offering treasures.

"Commander, you see, these stone powders have been crushed according to your instructions, and they have all been sifted separately."

Lin Hanlong glanced at the machine behind the middle-aged man, "How is the ball mill?"

"Okay, very good."

Lin Hanlong reached out and picked up the work record book hanging next to the machine: "Is there any looseness? Is the vibration normal?" Originally, the machine's work record was written by the operator himself, but workers who were still in literacy classes could not fill in these. The students from the national school could help out when they came, but Lin Hanlong had already assigned them jobs, so he just had to fill them in himself.

It took Lin Hanlong almost an hour after going to work to fill in records, inquire about equipment, and check inventory and products.

When Lin Hanlong was about to finish filling out the record, he heard someone calling him. When he turned around, he saw Zhan Wuya, Sun Li and others walking towards him. He filled out the records a few times, signed his name, and put the notebook back.

The veteran technicians of the machinery factory gathered around the broken spherical grinding wheel.

"It's obviously a casting problem. Look at this, it's a typical anti-white mouth." Lin Hanlong pointed to the cross section of the part. Everyone nodded and no one spoke.

This bevel gear was cast, but apparently something went wrong during the casting process.

"Hehe, it's inevitable." Zhan Wuya came out to smooth things over, "There are mountains of parts to be recycled in the scrap warehouse, and the people in the reliability office can't even do failure analysis."

"It doesn't matter if it's broken, just don't break my glass." Lin Hanlong didn't want to go into detail. This kind of thing happens every day in Quanlingao. Even the cannons used on warships have had accidents such as gear breakage. What’s more, here, “Can it be repaired?”

Sun Li, who had been getting closer to look at the cross section, shook his head: "I'm afraid it won't work. The cracks are visible to the naked eye, and you don't know how deep they are without flaw detection." He gestured, "If there are no cracks, it can be done by cold welding."

Zhan Wuya patted Lin Hanlong on the shoulder. "I'll make a better one for you." After the war, arms production slowed down, and there were still some materials originally prepared, so Zhan Wuya spoke with confidence.

"If you can do it in a new week, you can use the one that is used for surface grinding first."

Lin Hanlong shook his head. "You can't move the flat-grinding one. The Navy is in urgent need of the binoculars."

Zhan Wuya snorted. The first batch of products of the optical factory included the three-year-old 8x monocular telescope for the army (test, which is actually the simplest refractor telescope with a bamboo tube for protection and carrying). The Navy disdained such a crude thing. Customers, they require good vision, high light transmittance, easy to hold, good sealing, corrosion resistance and so on. They require binoculars so that they can compare with the army's equipment at once. Mass production The binoculars need to be ground to make right-angle prisms, which involves additional investment and staff expansion in the optical factory. Fortunately, Wang Luobin, who is far away in Sanya, also supports the construction of binoculars. He can make them fixed and put them in various watchtowers. As a professional in optics, Wang Luobin emotionally supports expanding the scale of the optical industry.

"If you grind it flat, you can get everything together in three to five days at most." Zhan Wuya paused. "Army, soil, navy, ocean, you're right. I wonder what the navy wants?"

Everyone chatted for a while and then gradually dispersed. For others, it is already close to dinner time. After eating and doing something, they can start their night's rest and entertainment. Those who have energy can even go to the maid to take orders. And Lin Hanlong's day has just begun. The temperature is relatively stable at night, which is conducive to the processing of optical parts.

More importantly, he can monopolize the power output and network of the Ministry of Science and Technology.

At five o'clock, "light music" played from the loudspeakers all over Lingao. People who work everywhere know that this is a call for workers on the night shift. When the music plays again, the night shift manager of each workshop will take roll call at the door of the workshop and then hand over the shift to the workers of the day shift. Workers from the optical workshop arrived one after another, burping, shaving their teeth, and joking with each other. Every small restaurant on the street will serve dinner in advance before the night shift workers go to work, so that they can eat enough and have the strength to go to work. Before the music started for the second time, everyone had arrived. Lin Hanlong stood aside with his hands behind his back, watching his workshop supervisor pick up the workers, line them up, and roll their names according to the roster. Lin Hanlong thought that these people could be arranged as neatly as an army. The working class was indeed naturally organized and disciplined. It's a pity that although most of these people are young, except for a few strong ones, most of them are weak due to long-term malnutrition. I'm afraid they won't be of much use on the battlefield. Thinking of this, he couldn't help but shook his head.

"Chief Lin! There should be 37 night shift workers in the optical workshop, but there are actually 37. Please give instructions!"

Lin Hanlong coughed and walked up. "Comrades! Today I will tell you something. Everyone knows that there was something wrong with the No. 4 grinding machine yesterday, and debris flew out. What I want to emphasize is that the safety measures of our machinery are very good. The debris was The safety net blocked it, and no one was hurt. Secondly, our safety awareness is still very insufficient, and we don't have a good grasp of safety regulations. After the g was worn out, there were people watching, but no one pulled the emergency stop lever. This is not possible! Go back to the You said, this is courting death!"

Seeing that the people below still didn't react, Lin Hanlong sighed inwardly and his tone became stern.

"If something like this happens again in the future, if you don't follow the safety regulations, you will be deducted! Team leaders should pay special attention to it. You are directly responsible. In addition, we will conduct safety drills from time to time, starting tonight." The workers' eyes changed. became serious. Deducting money is a serious matter. Safety drills take up rest time, so they are also serious matters.

Lin Hanlong was very satisfied when he saw that the workers were looking at him attentively. "That's it. Let's get started."

The safety attendant in the workshop checked the power transmission system of each equipment, and then checked the gas valve. Finally, he lit the gas lamp in the workshop, and the workshop, which had become dim, suddenly became bright. It was with gas lighting that large-scale industrial night shift production in Lingao became possible. Every time Lin Hanlong sees this scene, he feels that the contribution of the person who invented the gas lamp is no less important than Edison in this time and space.

The glass workpieces to be processed have been "on the tray" - which means that they are firmly stuck in a conical-shaped shallow metal tray with an adhesive made of asphalt and beeswax, and then the tray is fixed on a spherical bracket with screws. Finally, the entire bracket is installed on the grinding shaft. The workers in the grinding class work in pairs and confirm according to the work order that the parts on the upper plate are consistent with the settings on the grinding wheel.

Two people from the abrasives team in the general affairs class also sent the prepared abrasive paste to the edge of each grinding machine according to the work order, and then started to prepare a new batch. The people working the shift were also busy using machinery to press a new batch of workpieces into metal pallets. This is a very demanding job. When pressing into the workpiece, you have to move quickly while the glue is still hot, and you must ensure that it never becomes crooked. A group of two people from the mechanical class were busy starting up a grinding machine that had been prepared. The machine has been manually tested and there is no problem. It has been lubricated and the grinding team has confirmed that everything is normal.

According to the work order, this grinder will need to be rough ground tonight, and the selected speed is faster. For this reason, the belt needs to be moved to a smaller diameter transmission wheel. After moving it, re-tighten the belt, and then move the clutch lever to combine the fixed transmission wheel above the head with the main power transmission shaft. There was a squeaking sound from various parts of the machine, and then it started to grind and turn, and the noise slowly disappeared. The machinist glanced at the tachometer, signaled to the grinder that everything was OK, then stepped aside and began filling in work records. The grinder picked up a small brush and dipped it in the abrasive, and carefully applied it to the rotating workpiece. After a while, all the workpieces were covered with abrasive, so the grinding disc was put down and let it swing back and forth. The grinding machine then entered normal working condition. After a while, other equipment in the entire workshop also roared one after another, and the night shift production of the optical car officially began.

Lin Hanlong walked around the workshop again, paying attention to any unusual conditions and noises. Then he returned to the door of the office and saw Wu Nanhai sitting on a long wooden bench in the rest area of ​​the workshop.

"Eh? Why didn't you say anything when you came, Old Wu, and just sat here?" Lin Hanlong was a little surprised. Wu Nanhai, who had witnessed everything, sighed: "Old Lin, you are really meticulous in your work here! Hahaha."

Lin Hanlong motioned for him to come to the office to talk. Several naturalized staff members and Chu Qing were already waiting at the door of the office. He glanced at Chu Qing and remembered the pack of limited-edition cigars sent to him. Wu Nanhai asked him to trial-produce a batch of magnifying glasses, so he specially sent a few packs to him.

"It's a rare visitor." Lin Hanlong called on his apprentice to serve Wu Nanhai tea and water: "I don't have anything here, so I can't entertain you well."

"It's okay, it's okay, we're doing it for work too!" Wu Nanhai laughed, "I said I needed 50 magnifying glasses last time, and you made them in a month. It's amazing."

"If it takes a year to do it well, we don't need to engage in industrialization." Lin Hanlong said, taking the towel his apprentice twisted for him and wiping his face.

"By the way, I heard that Nanjing in the Ming Dynasty can make aging glasses and the like, using crystal flakes to grind them. Do you want to make a report and get some indigenous opticians to help?"

"Of course it's nice to have it, but I don't think it makes much sense. How many slices can a hand-made craftsman like this make in a day? It's nothing more than a luxury product that can only be enjoyed by rich and powerful people. Now I grind it by machine. Even if the quality is not as good as theirs for the time being, at least the cost is It cannot be compared with the production volume." He paused, "I am very interested in crystal. I heard that there is a large crystal mine in the East China Sea of ​​Lianyungang..."

"Haha, the people from the remote exploration team said last time: There are good crystal mines in Hainan."

The two people were talking when someone pushed a flatbed truck over from outside.

Lin Hanlong motioned for someone to take a flat wooden box from the car and place it on the ground beside the two of them. Open the box and find a straw mat inside. Take away the straw mat and take out five small boxes, also separated by straw mats. Lin Hanlong reached out and picked up a small box and opened it. Inside is a magnifying glass, embedded in the velvet at the bottom of the box. ! .
