The next day, Dong Lao officially appeared in the Dongxiang factory, listened to the report of the leaders of the Dongxiang factory on the current operating conditions of the enterprise, and made some instructions. Whether it is the report of Dongxiang Factory or Dong Lao's speech, it does not involve Feng Xiaochen's research in the factory. In Zheng Lisheng's opinion, Feng Xiaochen probably just pulled the tiger skin to make a banner, holding a few chicken feathers given by the Science and Technology Industry Commission as an arrow, and shook his majesty in front of them, but in fact he had no ability. Think about it, how capable can a 20-year-old graduate student be?

Dong Lao left after giving instructions, Feng Xiaochen also left after staying in the factory for two more days, and Dongxiang Factory seemed to be back to its original state. However, what everyone didn't expect was that two weeks later, the Science and Technology Commission issued an order to transfer Yu Zhongping, the secretary of Dongxiang Factory, and Zheng Lisheng, the director of the factory, from their posts and transferred to the Provincial Science and Technology Commission to hang up an idle post. Subsequently, the Commission of Science and Technology transferred new factory leaders from the east, and included Dongxiang Factory in the "Pilot Unit of Military-civilian Cooperation of Third-tier Enterprises".

The cadres and workers of Dongxiang Factory didn't understand what was going on with this "pilot unit" at first, but soon several uninvited guests came to Dongxiang Factory. Their letters of introduction were issued by the State Commission of Science and Technology, and their identities were the general manager, chief engineer and some other personnel of the private Chenyu Construction Machinery Company. The new director of Dongxiang Factory, together with a cadre in charge of production, technology and finance, negotiated with the visitors for several weeks, and finally signed an agreement that was very beneficial to Dongxiang Factory.

The agreement stipulates that Dongxiang factory and Chen Yu company to establish a strategic cooperative relationship, Dongxiang factory for Chen Yu company to provide parts and components OEM services involving precision machining and cemented carbide processing, the initial annual number of foundry is 10,000 sets, each set of foundry cost of 4,800 yuan. The foundry cost includes all the material costs, labor costs, electricity costs, equipment depreciation, etc., all of which are calculated, and the cost of Dongxiang factory is less than 3,000 yuan. This means that while the Dongxiang factory can feed the workers of the whole factory, it can also have a net profit of more than 10 million yuan a year, which is even better than the situation in the past when it undertook the production of military products.

The Commission of Science and Technology claimed that this business was contacted in the name of the Commission of Science and Technology, and in exchange, the Commission of Science and Technology required the Dongxiang Factory to invest no less than 8 million yuan per year in the research and development of new equipment, especially to maintain the stability of the scientific research team and continuously improve the level of scientific research. Gu Jianhua has already put forward the design ideas of two new products, one is a large-caliber self-propelled gun, and the other is an ultra-light howitzer. According to analysis, if these two products can be developed, even if China's troops cannot come up with the money to purchase them for a while, at least many countries in Asia, Africa, and Latin America will be interested.

Only a few people such as the new factory director and the old engineer Gu Jianhua knew that the reason why Chenyu Company was willing to cooperate with Dongxiang Factory was all thanks to Feng Xiaochen, the young master's student who had been walking around the factory a few days ago. Of course, except for Feng Fei, no one knew what kind of relationship Chen Yu Company had with Feng Xiaochen. When Yang Haifan came to Dongxiang Factory, he just said that he had some friendship with the "Director Feng" of the Heavy Equipment Office, and the "Hong Kong flavor" left on Zhang Guodong also made people believe that Chen Yu Company was actually a Hong Kong-funded enterprise, which naturally had nothing to do with Feng Xiaochen.

Feng Xiaochen is happy to be this behind-the-scenes hero, and he doesn't need people from Dongxiang Factory to thank him. In Dongxiang Factory, he took the line of Dong Lao, which was a great harvest. Dong Lao and Meng Fanze are both of the older generation, and they both have a considerable say in the industrial field. But compared with Dong Lao, Meng Fanze's influence is still slightly inferior. Dong Lao is a member of the military, and in many cases he can do things that are difficult to do under ordinary conditions under the banner of the military.

In fact, when he was still in Dongxiang Factory, Feng Xiaochen reached a verbal agreement with Dong Lao, that is, after the cooperation agreement between Dongxiang Factory and Chen Yu Company came into effect, Dong Lao was responsible for helping Feng Xiaochen win an opportunity to go to Africa and the Middle East. The reason Feng Xiaochen put forward was to help Gu Jianhua contact buyers of self-propelled guns and ultra-light howitzers, and by the way, to investigate the industrial equipment market in this region. At that time, it was more troublesome for domestic people to apply to go to Africa, but for Dong Lao, it was just a matter of phone calls.

On the day Feng Xiaochen returned to the capital, it happened to be the weekend, and he didn't bother to go back to the strategy office, so he went home directly. Du Xiaodi has been admitted to graduate school as he wished, and he usually lives on campus, and the two of them can only reunite on weekends.

"Xiaodi, I'm back!"

Pushing open the door of the courtyard, Feng Xiaochen shouted loudly.

Seeing a flash, Du Xiaodi had already come out of his room. She stepped forward quickly, helped Feng Xiaochen take the bag in her hand, and patted Feng Xiaochen's body casually, helping him pat off some of the dust on the road, and then complained with a smile: "Why didn't you say hello before you came back, I didn't prepare any dishes." ”

"If I don't come back, you won't cook by yourself?" Feng Xiaochen asked.

Du Xiaodi said: "Of course, a person's meal is well prepared, and you can deal with it with a bowl of noodles casually." ”

Feng Xiaochen said: "That's not good, you usually don't have anything to eat at school, right? Finally, I can go home on a weekend, and I can't eat better? Why don't you go to the vegetable market and buy two catties of meat, let's stew meat at noon?"

"Or ...... There are still eggs at home, can I scramble tomatoes and eggs for you?" Du Xiaodi suggested with a sad face.

"What, are you busy?" Feng Xiaochen sensitively noticed Du Xiaodi's strangeness. In the past, when they were both at home on weekends, Du Xiaodi would always buy a lot of vegetables and cook him a few delicious meals. Feng Xiaochen is a foodie, almost meatless, Du Xiaodi also knows his characteristics, so every time he cooks, he inevitably has one or two decent meat dishes. This time, he came back from a business trip, and in a common saying, it was called "a little don't win the newlywed", and Du Xiaodi had no reason not to buy meat to treat him. Now that she says this, she obviously means that she is very busy at hand and does not want to waste time going out to buy groceries.

Du Xiaodi was a little embarrassed when Feng Xiaochen told the truth. She said: "Actually, I wasn't too busy, but there was a process problem that was more troublesome, and I had been doing it for several days." Forget it, I'd better go buy meat and come back to give you stew. ”

"Don't ......" Feng Xiaochen grabbed Du Xiaodi, who was about to get the vegetable basket, and stared at her eyes and said. Only then did he realize that Du Xiaodi's eyes were full of bloodshots, and his face was also a little haggard, and even the green silk looked dry and lackluster.

"Xiaodi, what's the matter with you, you stayed up all night, and more than just stayed up all night. Feng Xiaochen asked.

Du Xiaodi lowered his head and said timidly: "Well, I haven't rested well in the past few days. The main reason is that my foundation is too poor, I have a lot of books to read, and there are ...... Some calculations are cumbersome. ”

"What the hell is going on, let's go to your room and see. Feng Xiaochen said, threw down his luggage, and pulled Du Xiaodi into her room. As soon as he entered the door, Feng Xiaochen was a little dumbfounded, only to see that the table and bed were full of books and newspapers, as well as some copies, printing paper, photos, and so on. Du Xiaodi has always been a girl who loves to be tidy, and her room has always been cleaned up and refreshing, but this time, Feng Xiaochen almost suspected that it was in his room, and it was so messy that people couldn't get down.

Judging from the information stacked on the bed, Du Xiaodi should have not gone to bed for a day or two. There is also a rice bowl on the windowsill, which has traces of dried soup, which can be guessed that it has been a long time since Du Xiaodi had his last meal. This is the so-called forgetting to sleep and eat, what kind of thing makes this girl busy like this?

"It was a topic given to me by Mr. Cai, about the welding process of 16MnR steel. Du Xiaodi looked at Feng Xiaochen and said in a somewhat timid tone. She originally didn't expect Feng Xiaochen to come back, and felt that no one would know about her hard work. Now that she has been caught by Feng Xiaochen, she suddenly felt a little embarrassed when she saw Feng Xiaochen's expression a little distressed and a little reproachful.

"16MnR steel is commonly used in pressure vessels and is an important structural material. The performance of its welded joints at low temperatures is critical for the longevity and safety of the equipment. We often say that the quality of a pressure vessel is the quality of its welding. In the past, I used to weld 16MnR steel in the factory, and we had some experience that we had found out on our own. A few days ago, I used several different processes to weld some workpieces at school, and the photos taken with the micro-electron microscope showed that several processes have different microstructures, which is consistent with our past experience. Mr. Cai attaches great importance to this result, let me prove this result theoretically. ”

Du Xiaodi lowered his head and introduced to Feng Xiaochen what he was doing. She knew that Feng Xiaochen's technical foundation was very good, and he would definitely be able to understand these things.

"This needs to be numerically simulated. Feng Xiaochen said, he glanced at the things on Du Xiaodi's desk, and roughly guessed Du Xiaodi's research ideas from the titles of those materials. He picked up a few pieces of scratch paper and looked at them, frowned and asked, "Xiaodi, you can't solve the welding heat equation by hand, do you?" This seems to be called the Rosenthal-Rykalin formula, which is very difficult to derive, or is it easier to use numerical simulations? ”

"Teacher Cai also said this, but the numerical simulation needs to use a computer, and the computer in our school is very nervous, and our laboratory can't be divided into a few hours a week, so I can't help it, so I want to use the analytical method to do it. Just such an equation, plus boundary conditions, I pushed it for three days and still haven't pushed it out. Alas, they all complain that my foundation is too poor, and I am not proficient in the formulas of many people's high school schools, so the efficiency is particularly low. Du Xiaodi said with a tone of self-reproach.
