Restarting life in Siheyuan

Chapter 200 The steel rolling mill is my mother’s family
Due to the construction of new factory buildings and the rush to work on small motorcycles, there are many people working overtime in the steel rolling mill, especially the relevant leaders. A lot of these small motorcycles have been produced, but there is still no one in the department store.

All ministries and commissions cannot supply it, and the demand in the factory is suppressed now. There is no gasoline, and you can't use it even if you buy it back. When the production capacity is increased next year, the problem of employees' needs will be solved, and the employees reluctantly accepted the explanations and arrangements.

We found the construction site. The factory building is almost finished. The outside has been finished. Now we are renovating the inside of the factory building. We are pouring cement into the workshop and fixing some equipment.

After wandering around, I finally saw the leaders. The director, secretary, deputy director Jiang, and deputy director Li were all there.

"Leader, we have something to ask for help."

Then several people turned around and saw Zhu Xuefeng.

"Why did you come to the construction site? Why are you so anxious about something? You are not idle on your days off."

"Director Yang, from what you said, aren't your leaders also busy? Besides, the steel rolling mill is my mother's family. If this is not a problem, I will ask my family members to come."

"Okay, you've been to school for a few days and you're good at talking. Tell me what's going on."

"I want to get some thin aluminum plates and make a few shells. They're just this big. I'll pay for the materials when I get to work on Monday."

"That's all. Today I'm taking the labor grade exam. There are materials on site. Just go to the workshop yourself. I don't believe you kid doesn't have this ability."

"Thank you, director, secretary, deputy director Jiang, and deputy director Li. If you excuse me, I'll leave first."

It is necessary to say hello, otherwise it will appear that you are too casual in the steel rolling mill. After all, you are not from the steel rolling mill, and aluminum plates are not considered ordinary materials.

When I came to the third workshop, it turned out that many people were taking exams. The last round of exams this year was just in time for a salary increase next month.

After chatting with Director Sun for a few words and entrusting the master to build it for him, Zhu Xuefeng sneaked to the Materials Research Institute. He hadn't been here for a month and didn't know how the research on ductile iron in the rolling mill was going.

I only took the time to come back twice last time and finalized the plan. First, I had to modify the experimental furnace and increase the furnace temperature. Deputy Director Zhao was very easy to communicate with. As long as the technicians from the Materials Research Institute approved Zhu Xuefeng's plan, they would not hesitate. stop.

"Director Chen, hello, excuse me, I'm here to learn about the technical research of ductile iron."

The director of the Materials Research Institute is also a division-level cadre. He has been in the factory for almost ten years. The older generation of college students is still very knowledgeable. He strongly supported several of Zhu Xuefeng's ideas before they became plans.

"Hey, Xuefeng is here. He said that you are going for military training. Come on, let me show you our progress. We have produced more than 80 experimental samples now. We need to find some direction."

"So fast? Have the experimental conditions been changed?"

Zhu Xuefeng was surprised. According to his assumption, it would be good to barely change the experimental conditions in a month.

Director Chen also smiled bitterly. Several factory directors have worked with the Materials Research Institute. They come here when they have nothing to do. I really want to experiment and find out the right ratio tomorrow. The Materials Research Institute has been working overtime every day during this period, and I am almost exhausted. Day and night are gone.

Some people are modifying the experimental conditions, some are studying the experimental plans, and some are theoretically deducing the ratio. The factory also gives them what they ask for, and everything is given the green light, which is why we have the current situation.

"Let's go to the analysis room and take a look."

Researchers are also extremely busy. Unfortunately, there is no suitable metallographic microscope. They can only rely on simple instruments and chemical analysis methods to carry out research. The efficiency is not high. The research conditions here are still worse than those in the Department of Physics.

Early ductile iron actually obtained spherical graphite through spheroidization and inoculation, which effectively improved the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining higher strength than carbon steel.

"Director Chen, you go about your business. I'll see for myself and learn from it." "Okay, you can see for yourself. Don't tell me, your plan makes sense to me, and now we have a taste of it." A little direction, I’ll go there first.”

Director Chen still admires Zhu Xuefeng for coming up with this plan at such a young age. He is also an expert in materials research and really knows his stuff.

The samples on the table are numbered, and each piece clearly records the detailed ratio and experimental conditions. Each piece records the data of various intensity experiments. The research is very standardized.

Picking up the sample piece, Zhu Xuefeng used the perspective function and carefully scanned it piece by piece, while recording the internal metal composition he saw through perspective.

Although I can't remember the internal structure of real ductile iron, I still have a general impression. I found four groups of internal structures that are closest to those of later generations, made key marks, and checked the data and proportions of the four groups.

After thinking for a long time, I completed a further implementation plan, which is expected to advance the research progress a lot. This is a typical cheating. With the general situation of the internal structure diagram of later generations and the cooperation of perspective, it is impossible not to speed up the process.

I went to Director Chen with the experimental plan. The two chatted for a long time. Director Chen agreed to try the new plan. If the key points can be found in advance, the steel rolling mill can save a lot of materials.

Seeing that it was getting late, I said goodbye to Director Chen and hurried to the bun shop of the joint venture store. Uncle Zhang had already finished packing and was waiting.

"Uncle Zhang, I'll take you to have a look first. You can move there when you have time. Isn't this small shop still yours? You might as well open it someday."

"It's difficult, the old man can't really handle it alone. I've done it by myself these two days."

Only then did Zhu Xuefeng remember that the old man hadn't made steamed buns for a long time, probably because of the flour. These steamed buns also cost flour, and the added value is not as good as steamed buns.

"Uncle Yang, this is Master Zhang. I invited him to take charge of everyone's food."

"Great, this is really troublesome for my nephew. Don't say anything. I will arrange a place to stay for you."

When outsiders come, everyone is treated as uncle and nephew. When the door is closed, they are treated as uncle and brother.

The six people have settled down, plus Gao Bo and Xie Minghui who often come to practice martial arts, and Coach Gao who comes to visit from time to time. There are usually nine people in the yard. When Master Guo's two apprentices come again, there will be 11 people.

Except for Uncle Yang's two nephews who could barely cook, no one else could. They helped each other together every time, and the more they helped, the more chaotic the situation became. After settling down, the problem of eating has always been a big trouble.

I have never been able to find the right person. Now it's better. Zhu Xuefeng has solved it. Everyone will be more relaxed in the future.

From now on, Master Zhang will be responsible for cooking, and Master Yang's nephew will help, and the problem will basically be solved.

Finally, accommodation was arranged for Master Zhang in the outer courtyard. Master Zhang was responsible for three meals a day and looking after the gate. As for the cleaning and tidying up in the courtyard, he didn't need to worry about it.

Master Zhang is also quite satisfied. He has settled down, has something to do, earns money, and lives in a good place. There is nothing he is dissatisfied with.

"Then I will change my name to your boss. Don't worry about the matters in this yard. Not a word will be leaked out."

The old man had long seen the row of training equipment in the front yard. It seems that the people in this yard are all practitioners, but the people are quite friendly, but no matter how friendly they are, they are not ordinary people. You should be careful about this. .

"Master Zhang, don't worry, there are no bad people here. As time goes by, you will know that this is a place where martial arts enthusiasts gather, and everyone comes together to communicate."

　Regarding ductile iron, let me give you an example to deepen your understanding. Nowadays, manhole covers in streets and alleys are made of ductile iron, which is strong and durable, has high strength and toughness, is wear-resistant, can withstand shocks, is not easily deformed, and can withstand various harsh environments.
