At present, there are not many research institutes of material factories, but in the foreseeable future, the research institutes of material factories will definitely increase, and in the near future, it is imperative that each research institute be divided into more research institutes. The reason is also very simple, with the increase of projects, the management will become more and more difficult, in this case, in order to facilitate management, the only way to separate the projects with too different research directions is to carry out professional management.

In this case, the researchers of the material factory will inevitably increase significantly in the future, so there will be more and more teachers in this school, and finally Li Zhao is also ready to use this school to develop a university, so that more talents can be sent to the material factory at that time, instead of being short of people everywhere like now.

In particular, related majors such as aircraft manufacturing, computer and electronic technology have been cutting-edge industries until the future, and it is very unrealistic to recruit people in the market. What's more, these high-tech industries are also industries that have been sanctioned for a long time, and if they do not develop as soon as possible, the gap between them and others will become wider and wider in the future.

Therefore, He Yushui came to study in this school, that is the best choice, as long as the grades are about the same in the future, at least one undergraduate will not be able to run. And He Yushui is also very happy, so that she doesn't have to live in the school, she knows how bad the school food is, if she lives in the school, she won't be able to eat the good things at home. You must know that He Yushui has suffered a lot, Li Zhao only came to that meeting, He Yushui is often hungry and full of meals.

You must know that He Yuzhu is a chef, and the meals are often not at home, and he is also a careless person, and when he remembers it, he has a sister, what is his sister if he forgets? But now it's different, now that there is Lou Xiao'e at home, someone finally cares about her, and Lou Xiao'e is still a master who is not bad for money, so life is naturally better, which is definitely not comparable to the school canteen.

In addition, she also wants to live in a building, through the chat just now, she knows that the decoration of all houses is almost the same, maybe things are not as exquisite as Li Zhao's house, in this case, if she lives upstairs, the living conditions can be imagined, and the most important thing is that there is a bathroom at home.

Looking at the scenery here, everyone sat for a while, and then went back, after all, it was work time at this time, and Lou Xiao'e was still in charge of a canteen, and it was almost time to eat. Nastya doesn't care, she doesn't have much to do, and she goes back to fish. He Yuzhu doesn't matter, he is now in the cafeteria, and basically no one will let him do it himself, after all, Director Yang knows He Yuzhu's level.

And Lou Xiao'e is still the director of the canteen, and she is about six months pregnant, He Yuzhu needs to serve this Lou Xiao'e all the time, he is afraid that Lou Xiao'e will have any problems, and she will have to stand aside for work or something.

Su Ya went to the material factory to continue working, while Li Zhao was about to go to the rolling mill and think about the aluminum alloy profile production that he had just thought of, so he said goodbye to Su Ya at the intersection and followed He Yuzhu and Wang Jun to the rolling mill. And He Yushui followed Nastya back to the courtyard together, and he and Li Zhao and a few people left together. The reason why I went to the rolling mill is also simple, this product is civilian, and it is more suitable to be placed in the rolling mill. As soon as Li Zhao left like this, she also confused Nastya, because she always felt that Li Zhao was inextricably linked with the material factory, so she left Su Ya to go to the rolling mill so directly, which made her very ignorant, in short, she was very suspicious of Li Zhao.

When it comes to aluminum alloy profiles, in fact, the production is quite simple, first the aluminum is melted and cast into aluminum rods, and then the molds of the corresponding sections are designed according to the needs, and then the aluminum rods are extruded into the corresponding aluminum profiles on the extruder, and then the aluminum profiles are cut into the corresponding lengths according to the needs, and the overall process is very simple.

It's just that because there are many types of doors and windows, if you want to realize all types of doors and windows, you need more molds. In the future, the commonly used doors and windows are divided into two categories, two series of push-pull and swing opening, and then divided into 60, 80, 88 and other series according to the size. Later, because of some special needs, such as reducing costs and increasing strength, several series were developed, which were derived from new sections, and the production process was no different.

In addition to the series, the materials are divided into frames, fans, stands, beads, etc. according to the use, in this case, there should be at least seventy or eighty sets of molds that need to be designed, so that common doors and windows can be produced.

The use of aluminum profiles is also very simple, using the cutting machine of alloy steel saw blades, you can directly cut the aluminum profiles into the corresponding shapes according to your needs, and then splic, and fix them with self-tapping screws. Of course, rubber strips are also needed when installing glass, and this production is not a problem for Li Zhao, only a single-screw extruder is needed, which is simpler for Li Zhao, but Li Zhao doesn't know if the rubber is enough.

After all, synthetic rubber is still relatively backward in this era, and now the domestic demand is very large. Now the only problem is that Li Zhao has not produced aluminum profiles, Li Zhao needs to calculate the cost of aluminum alloy profiles, and finally roughly calculate the price of one square meter of aluminum alloy profiles doors and windows, to see if it is affordable in this era, too expensive will not be.

While walking, I was thinking about how to produce aluminum profiles, and in this era, automation should not be considered, and only manual labor could be used, so that more people could be arranged. When he came to the rolling mill, Li Zhao went to his office and began to calculate, first of all, to design the section of the aluminum profile, there is no problem with this, Li Zhao has it in his mind, after all, he has produced molds in this area. Then, according to these sections, calculate how much aluminum alloy is needed for a door or window, and then calculate the price.

After some calculations, Li Zhao found that the cost price is about more than three yuan per square meter, this price is acceptable, ordinary people's houses, only three or five windows, ten square meters is too much, so the price of aluminum alloy windows in a house is more than 30, counting the profit, it is estimated that there is 50. This price should be acceptable, after all, there are not many people who can live in high-rise buildings.

If you live in a high-rise building, it is still more dangerous to use wooden doors and windows, compared with aluminum alloy, wooden windows are easy to decay, and high-rise buildings are relatively windy, if you use wooden windows, there may be hidden dangers.

After the calculation was completed, Li Zhao went to Director Yang, and he needed to ask him about the project to see if it needed to be produced. After meeting, Director Yang said directly: "Rare guest, you don't often come to the rolling mill during this time, do you have something to do today?" Then he invited Li Zhao to sit down, then poured Li Zhao a cup of tea, and sat on the sofa to chat with Li Zhao. Li Zhao looked at the house for so long, he was really a little thirsty, took a sip of tea and said: "This is also no way, I have too many projects in my hands, although there is the help of the research institute, but there are also a lot of things that need me to do." Today's words are thinking of a product, and I want to ask if the factory is interested in engaging in it, this is a civilian thing. ”

Then Li Zhao told Director Yang about the situation of aluminum alloy profiles, and after listening to Li Zhao's introduction, Director Yang thought for a while and said: "Things are good things, but this product needs more aluminum, I don't know if the superiors will agree." This is just a window, a bit overkill, and our profits from producing bicycles are much higher than this. And we obviously can't operate this directly, and the size of this window can't be unified. ”

Good guys, this is also beginning to pick and choose, it seems that this period of time has been too moist, Li Zhao said: "Unified size can also be, such as direct supply to the supply and marketing cooperative, who needs to change the window, directly change the window to our unified size is, and then such as a building, you can also directly design according to the size of the window." ”

However, Li Zhao said that it is easy, and it is difficult to do it, but Li Zhao also has an indifferent attitude towards this project, and the demand for windows in this era is relatively small. This is also the reason why Li Zhao thought of this direct calculation and came to Director Yang, if it is a project that Li Zhao must implement, Li Zhao will directly take out the drawings, this time it is ready to be designed after Director Yang agrees.

Director Yang said in a deep voice: "I still ask the opinion of the superiors, this project is not a necessary project, we still have wooden windows to use without this aluminum alloy, and now our aluminum supply is very tight, so this project is best to see how the superior arranges it." ”

When Li Zhao heard this, he nodded and said, "Yes, I also suddenly thought of this, so I came to ask for advice." "In this era, in addition to the need for tickets, the supply of industrial products has also introduced industrial coupons, which also makes the purchase of industrial products more difficult, of course, the reason is very simple, the market demand is relatively large, and so many products cannot be produced.

After the production of aluminum alloy doors and windows, it will also face such problems, so it is best to communicate with the superior first, and don't let the production be stopped at that time, after all, the product proposed by Li Zhao this time is not irreplaceable.

Director Yang felt a little strange at this time, and he didn't know why Li Zhao suddenly thought of the window, so he asked: "You are strange, why did you suddenly think of the window, you don't seem to have been in charge of construction matters, right?" ”
