Li Hui made a meal and followed others to sit down at the table. He said to Zheng Gangzhong: "I didn't expect that the people who work here eat so well."
Zheng Gangzhong pointed to the other side and said: "How is it possible? We are guests today, and the food is particularly good. I saw what the workers over there eat, and there is only tofu and fish, no meat. If you eat like this every day, you can still make money what money!"
"That's it!" Li Hui nodded in realization. "Many of us officials can't afford to eat meat every day, let alone these workers."
Fish is difficult to transport and prices vary widely depending on the location. For example, along the Yangtze River, especially in Ezhou, the price of fish is extremely low, as if it is free. In inland areas where water is scarce, prices are higher. It is near Luoshui, the surrounding population is small, and the price of fish is very cheap.
There are three types of rice, white rice, yellow rice and steamed buns. Li Hui is from the north. He took three big steamed buns and ate them hungrily with the vegetables. There were too many people in his family, and he was living a hard life relying on his own official salary. There is meat and fish today, so of course we have to eat more.
After finishing the meal, Lin Zeng and He Wei led everyone to put the tableware in the designated place and walked out of the cafeteria.
Lin Zeng said: "After dinner, rest for half an hour. The space in the workshop is limited. You can go to the class just now, or just sit outside. I will come to you in half an hour and we will visit the workshop together."
After that, he went straight.
Everyone didn't know what to do and looked at He Yan.
He Yan said: "If you want to go to the room, just follow me to the classroom. If you don't want to go, just rest under the shade of the trees. This is a factory, don't wander around!"
Everyone said yes.
He Wei took some people to the classroom, and the rest sat under the willow shade, chatting.
Gongcheng Bowen said to Mu Ying: "Brother Mu, what are we doing here? What the Pang official said today was so confusing that I couldn't understand a word of it. I saw that you wrote down a lot in your notebook. Listen. understand?"
Mu Ying said: "What do I understand? I just remember what the official Pang wrote on the blackboard. I have been reading books about sages since I was a child, so how could I know what a bearing is! And I have built such a big factory. I don’t know what kind of use it is.”
Everyone said yes, and everyone complained. It’s more than 200 miles from Luoyang to here, and that’s all?
Zheng Gangzhong said: "I think that under Xuanfu's rule, there will be many such factories in the future. Let's take a look at what the factories are like. What kind of work they do and what kind of life they live. No matter what I can’t understand it either, we have already met before after all.”
Mu Ying nodded: "I guess that's the case. If not, what are we going to do?"
After finishing speaking, he flipped through his notebook. Said: "The next thing I want to see is how the bearing is made. Just now Pang Guan said that the bearing made here has a total of four parts. They are the inner ring, the outer ring, the roller and the cage. This thing looks simple , but it is not easy to do. Cars produced here generally have two bearings installed on the axle, so they run very briskly."
Gongcheng Bowen shook his head: "I don't understand! I don't understand a word of what that Pangguan man said!"
Others listened and said they didn't understand.
Zheng Gangzhong sighed. I didn’t understand it either. I have never been exposed to these before, so I don’t know what they are talking about.
After about half an hour, Lin Zeng came over. Let each team leader form a team and prepare to enter the workshop.
The team is organized. Lin Zeng said to everyone: "Every worker in the workshop has his own things to do and cannot be distracted. After everyone enters the workshop, remember not to talk and just watch silently. Even if there is something you don't understand, speak up." I’ll ask after the workshop.”
After explaining some precautions, he led the people to the first workshop.
Lin Zeng did not take people to see the parts in the order of production, but based on the location of the workshop, from near to far.
The first workshop is for the production of rollers. The rough-processed rollers are sent to this workshop, where they are manually polished, measured, and then packaged by workers. Each production line is not long and arranged neatly.
Everyone is divided into several groups, each group visits a production line, and the group leader maintains order.
.
Zheng Gangzhong walked to a production line. Next to the production line were several wooden boxes containing many round iron blocks. A worker lifted a box and poured the iron blocks inside onto the workbench in front of him. The workbench in this part is an inclined surface, and when the roller is tilted up, it rolls into the groove below. The groove is wider at the front and becomes narrower towards the back. From time to time, workers would use their hands to arrange the rollers on them so that they could line up neatly.
In front of him, there were several workers riding on a frame, constantly pedaling like water wheels draining water. I saw iron filings leaking out from the groove where the roller was located. The rollers in the groove keep moving forward.
Zheng Gangzhong opened his eyes wide and looked at the machine, but he couldn't see how it worked.
Walking to the back, the rollers in the groove have become very bright, and there is no trace of rust except at the two ends.
The two workers at the back picked up the roller that came out of the trough and stuffed it into a cylinder in front of them. Some are put in the back, and some are put in the box on the side. Zheng Gangzhong watched for a long time and didn't know how to distinguish this person.
The separated rollers were installed by workers in front and placed on a machine to smooth both ends. After smoothing, put it into a small wooden box.
Not long after looking inside, Lin Zeng led everyone out. He stood outside the workshop and said to everyone: "If you have any questions, you can ask me."
Zheng Gangzhong couldn't help but asked Lin Zeng: "This workshop makes rollers, but I don't know why the back becomes smooth?"
Lin Zeng said: "Have you seen the people pedaling? Their strength drives the rollers and grinds them smooth in the grooves."
Zheng Gangzhong thought for a while, but still couldn't figure out how to polish it smooth. But it’s not easy to ask anymore, so I can only frown and think about it.
Li Hui said: "I saw two people stuffing the rollers that came out into the cylinder. Some put them at the back, and some put them to the side. What are they doing?"
Lin Zeng said: "They are inspecting. One of the inspection tools used is passed and the other is failed. Passed means that it is too small, but naturally it is too big. Whether it is too small or too big, it must be rebuilt and selected to pass. can be used."
Li Hui nodded. I don’t know why two tubes that look the same can pass and the other can’t. It's not a good idea to ask, just think about it.
Someone starts, and others follow. These people asked all kinds of questions, and Lin Zeng answered them one by one. But even if they answered, most of them still listened as if they hadn’t. At most, they know what the workers are doing, but they don’t understand why they are doing it.
Machine manufacturing, before the large-scale application of steam engines, and some even before the large-scale application of electric motors, relied heavily on manpower. The efficiency of this method is relatively low and the production speed is slow, but most products can be produced.
Bearings are basic components of machines, and most machines are inseparable from them. With bearings, precision machines are possible. Without bearings, or just simple bearings, the machine industry is unimaginable.
Wang Xiaolie built the bearing farm to lay the foundation for the entire industry. With this foundation firmly established, many machine industries can begin.
