Siheyuan starts from a better life

Chapter 245, goodbye big leader
In fact, Jiang Yan plans to take out this alloy steel for another purpose, which is to increase the mining of chromium ore.

Chromium is a silvery-white lustrous metal, pure chromium is malleable, and chromium with impurities is hard and brittle.Chromium has high corrosion resistance. In the air, even in a hot state, it oxidizes very slowly and is insoluble in water.

Because chromium has these characteristics, it is widely used in industry, especially military industry, and it can be called a "strategic metal".

It is said that chromium is a famous strategic metal, because it has many wonderful uses in military weapons. With it, the performance of many weapons will be greatly improved.

The first is the problem of "chrome plating" on the inner bore of the gun. Its function is to resist wear and ablation, thereby prolonging the service life of the barrel and barrel.

When the gun is shooting, the combustion of the propellant in the chamber will produce a large amount of high-temperature and high-pressure gas, which will have a strong scouring and ablation effect on the inner wall of the barrel and the barrel, and the high-speed movement of the projectile and the inner chamber will also produce strong The friction seriously affects the life of the barrel and barrel.

If the performance of barrels and barrels is to be improved, some special protection must be given to their bores.Chromium has high hardness, good wear resistance and high melting point, so chrome plating on the barrel and the inner wall of the barrel can play a very good protective role and improve the service life.

Although it is said that there is no such chrome plating technology in China at present, Jiang Yanhui will!He has three chrome-plating techniques in his hands.

However, Jiang Yan forgot one thing: the word chromium was named after the 60s, and the promotion of chrome plating technology in my country was also in the 70s and [-]s.

In other words, there is no name introduced in Chinese characters for the word chromium in our country.

The information went through Jiang Yan's mind quickly.

Jiang Yan comforted Zhang Xiang. "There will be bread and milk. Don't be depressed. Let's just work hard."

"I'll write down the secondary quenching process for you in a while. Let's solve the problem of availability first, and we will solve other problems."

After Jiang Yan finished speaking, he took a piece of paper, and wrote down the key points of the secondary quenching and subsequent cooling in detail on the paper and handed it to Zhang Xiang.

After Zhang Xiang read it, he solemnly put away the piece of paper.

Seeing Zhang Xiang put away the paper, he said, "Tomorrow, we will start maintenance on all the lathes in the factory, and everyone is ready."

"Then do we still need to draw the drawings of the relevant parts?"

As soon as Jiang Yan finished speaking, Wang Tianlai said something.

Hearing Wang Tianlai's words, Jiang Yan couldn't help but widen his eyes. This kid really dared to think. Jiang Yan has counted that although the machine tools in the [-] Factory are all German equipment, there are more than a dozen types of them. It is estimated that it will take several years to get all these out by myself.

Thinking of this, Jiang Yan suddenly remembered that it seemed a little unreasonable for the First Machinery Department to send him here. Although the engineers here don’t understand German, what’s their background, it’s not difficult to repair some machine tools. It has already entered the country early, so there is no reason why they don't know about it.

What's more, everyone's enthusiasm for learning is very high in this year, why it doesn't work here, all of this reveals a kind of weirdness.

However, this doubt was quickly resolved by Zhao.

Two days after talking with the two engineers, Jiang Yan was instructing workers to disassemble a lathe when Guo Jianjun hurried over from outside.

"Jiang Gong, the factory manager asked me to call you to a meeting."

"The meeting, did something happen?" Jiang Yan asked in a low voice.

"I don't know, but I heard that a big leader is here and wants to see you."

"Boss, see me?" Jiang Yan pointed to himself and asked Guo Jianjun.

"Yes, I see you, Mr. Jiang, please tidy up!"

After Jiang Yan responded, he handed over the dismantling work to Lao Wang and Lao Zhang, packed up the things at hand, washed his hands and arranged his clothes, and followed Guo Jianjun to the conference room.

"Secretary Li, why are you here?" At the gate of the conference room, Jiang Yan saw the secretary of the big leader, and hurried forward to say hello.

After Jiang Yan greeted Secretary Li, he knew that the leader here was Vice Minister Zheng.

"It's better to feed people in the Northeast. I think you're getting fat, and your head has grown a little bit."

As soon as he entered the meeting room, Jiang Yan was ridiculed by the big leader sitting above.

But Jiang Yan didn't reply. After saying hello to the big leader, he found his own seat and sat on it.

"Leader, everyone is here." Seeing Jiang Yan sitting down, Director Zhao, who was sitting next to the big leader, whispered to the big leader.

"Secretary Li, distribute all the materials to those who are doing it."

Secretary Li was distributing the materials, and the big leader sitting on top said, "This meeting is classified as confidential. Please sign it."

As soon as the big leader's voice fell, a piece of paper was passed from Director Zhao, and everyone who passed it signed a letter on it, of course Jiang Yan was no exception.

After signing, Secretary Li handed Jiang Yan a document. Jiang Yan opened it and looked at it. It recorded the introduction of the MiG-17 jet aircraft by the country, and later asked the [-] Factory to develop the aircraft on board. Regarding the matter of body metal, the last page is some basic information on the aluminum-magnesium alloy that Jiang Yan submitted before.

After reading this document, Jiang Yan raised his head and glanced at the big leader sitting on it.

If I didn't guess wrong, it's a lie to let me come here to repair the machine. The real intention is probably to produce this magnesium-aluminum alloy!

Jiang Yan thought for a while and understood the meaning.

The rolling mill where I work is an ordinary steel production enterprise, and the confidentiality measures are far less good than the [-] factory here. If I produce this aluminum-magnesium alloy in the rolling mill, I am afraid that there will be a risk of leaking the secrets. It is estimated that the big leader is considering it. This situation led me to come here to produce this aluminum-magnesium alloy.

Another point is that Bingcheng is relatively close to the newly established Shengjing Aircraft Manufacturing Factory, which makes transportation more convenient.

"Everyone wrote in their hands that it is an aluminum-magnesium alloy. This formula has been determined by the research institute and has the ability to be mass-produced. The First Machine Department has decided to organize production by our [-] factory. The specific production manager is Jiang Yan. .”

When the big leader said this, some people looked at Jiang Yan with different eyes. Some people were a little bit aggrieved when they saw Jiang Yan was young. They didn't know why the higher authorities appointed him to carry out the production. Anyone with a discerning eye knew that the formula on the information was already very detailed. Yes, as long as you follow the formula above, you can get a qualified product after a few experiments. This is the credit to your hands!

But before he opened his mouth to object, the words of the big leader caught everyone's attention.

"Everyone is very confused about why Jiang Yan was appointed as the main production manager. It's not because of anything else, but because the inventor of this aluminum-magnesium alloy is Jiang Yan. I think everyone who is doing it knows the situation better than him!"
