God-level Big Mine Owner

These two people are not simple, they are both senior experts, one is a senior expert in the field of materials, and the other is a senior expert in the field of aero-engine.

As a senior expert in the field of Huaxia aero-engines, Lin Yunwen is in charge of the development of a national key model aero-engine. At present, he has encountered major difficulties, and also major difficulties in materials.

The progress of this aero-engine was good at the beginning. Not only has the design been successfully completed, but also the trial production of the first verification machine has been completed. This verification machine has also been tested on the test bench. Not ideal.

After careful analysis by the entire scientific research team, the problem is not in the design, nor in the manufacturing process, but in the material.

Taking advantage of his friend Xu Jiaxiang's birthday this time, Lin Yunwen specially took the time to come over to congratulate Xu Jiaxiang on his 50th birthday. On the other hand, and most importantly, Lin Yunwen wanted to seek Xu Jiaxiang's help.

Unfortunately, when Lin Yunwen explained the situation, Xu Jiaxiang also felt very troubled and helpless. This is a key type of aero-engine, and the requirements for materials are very strict. Even Xu Jiaxiang has no way to solve this material problem.

Lin Yunwen's heart is full of disappointment, and now his mood is slightly lower, and he is ready to leave Jiangnan Province and continue his research after returning. Lin Yunwen even has such a plan. It is really impossible to solve this material problem, so he can only change the design structure and reduce the requirements. However, in the same way, the overall performance of this aero engine will drop a lot.

Helpless, there is no other way, it seems that we can only sacrifice the overall performance of the aero-engine, Lin Yunwen thought so frustratedly.

Wang Xudong heard the content of the conversation between the two clearly. Wang Xudong turned around and looked at the two people curiously. Wang Xudong even saw that Xu Jiaxiang lightly patted Lin Yunwen on the shoulder, which was comfort, and then lightly Sigh lightly.

Wang Xudong moved in his heart. He is one of the shareholders of Sanlian Special Steel. Although he is standing behind the scenes, if Sanlian Special Steel can attract customers, especially military customers like this, if the special steel of Sanlian Special Steel can be used by the military. It is a great thing to purchase from the side and apply it to military products.

Eight or nine out of ten domestic aero-engines are used by the military. That is to say, if the special steel of Sanlian Special Steel can be used on aero-engines, the heaviest user is the military.

Wang Xudong wanted to say loudly, I can solve your problem, but Wang Xudong knew that if he really said that, and the other party didn't believe it or not, he might think he was a lunatic.

Knowing this in his heart, Wang Xudong was very particular about strategy. With a friendly smile, he looked at the two of them and chatted up, You are experts, please, we are not in a hurry.

There were many people checking in. Wang Xudong had several people in line, and Lin Yunwen and Xu Jiaxiang were just behind Wang Xudong.

Lin Yunwen said: Young man, it doesn't matter, come first, come first, you should come first.

Wang Xudong had a good impression of Lin Yunwen and Xu Jiaxiang. The two saw that Wang Xudong was young and polite, and they had a good impression of Wang Xudong.

Just now, when the two of them were chatting, they paid great attention to confidentiality. I guess they knew that this was a public place. When they talked, they only mentioned key models, aircraft engines, troubles and other words. They didn't mention any materials. Engine model, verification test details, etc.

However, Wang Xudong guessed that the two people had difficulty in transporting materials. Sanlian Special Steel should immediately start the furnace to smelt the first batch of super stainless steel. Wang Xudong wanted to sell it to the two.

Wang Xudong was really hitting right.

Wang Xudong said: The two of you, the Sanlian Special Steel Group in Wujiang City, is about to smelt the world's most advanced super stainless steel. This is a very remarkable stainless steel material, which not only has absolutely first-class corrosion resistance, but also has good mechanical processing. Performance, super mechanical structural strength, I wonder if you two are not interested?

Lin Yunwen's eyes lit up, but his eyes quickly dimmed. He sighed slightly and thought to himself, Sanlian Special Steel, I have never heard of it. I guess this so-called super stainless steel is not much better, so I don't want it myself. Hope out.

This aero-engine developed by Lin Yunwen has two major material problems, one of which is the stainless steel material problem.

In general, titanium alloy materials are widely used in the compressor part of aero-engines, because this material is corrosion-resistant, small in specific gravity, light in material, and high in mechanical strength, and is the first choice for cold parts like compressors.

But titanium alloy is not perfect, it has a fatal disadvantage, that is, it is not resistant to high temperature. To improve the overall performance of this aero-engine, it is necessary to increase the compression ratio in design. The higher the compression ratio, the higher the compressor. As the compressed air is compressed step by step in the compressor, the temperature also increases step by step, and the temperature of the following stages of the compressor reaches hundreds of degrees, which exceeds the limit of titanium alloy, it must be Made of stainless steel.

High-quality stainless steel materials are also corrosion-resistant and have good mechanical strength. The only point is that the specific gravity is larger. In order to improve the compression ratio and the overall performance of the engine, although the stainless steel material has a larger specific gravity, it is compared with the overall performance improvement. , totally worth it.

Of course, the material problems encountered by this new aircraft engine are not only stainless steel, but also a high-temperature material, but if any of them can be solved, it will definitely be a huge surprise for Lin Yunwen.

It's a pity that Lin Yunwen didn't believe it. He didn't believe that Sanlian Special Steel, which Wang Xudong said he had never heard of, could develop stainless steel materials that meet the needs of advanced aero-engines.

Lin Yunwen knows the harshness of the material requirements of aero-engines, especially advanced aero-engines.

Seeing that Lin Yunwen didn't believe it, Wang Xudong just shook his head lightly and didn't continue the conversation. Wang Xudong's meaning was obvious, I've already given you the opportunity. If you don't believe it yourself and lose this opportunity, that's your own problem.

Brother, it's our turn.

Liu Yu shouted at the front, Wang Xudong smiled, and did not chat with Lin Yunwen anymore, but took a few steps forward and started to help Zheng Xiaotong check in, get the boarding pass, and the three walked towards the waiting hall together. .

When he walked to the door of the waiting hall, Zheng Xiaotong was obviously reluctant, because he was about to separate soon, Zheng Xiaotong was going back to the capital, and the two would not be able to see each other again for at least a week.

Brother...

Zheng Xiaotong's eyes suddenly turned red, and big tears were about to flow down. With a pitiful look, Wang Xudong felt very distressed.

Wang Xudong hugged Zheng Xiaotong gently, and kissed Zheng Xiaotong's forehead gently. Who knew that Zheng Xiaotong had a huge reaction, so he hugged Wang Xudong and kissed him actively.

There are many people at the airport. According to Zheng Xiaotong's character, he would definitely not kiss Wang Xudong in such a place. But thinking that he is going back to the capital soon, after returning, he still doesn't know what his family thinks of his future marriage. Attitude, whether to accept Wang Xudong or not, Zheng Xiaotong has no idea at all.

Zheng Xiaotong knew that his father had a good impression of Wang Xudong, but apart from his father, his mother obviously didn't like Wang Xudong. In addition, the Zheng family was such a big family, which was different from that of ordinary people. What about the attitude of others.

More importantly, Zheng Xiaotong also knows that his grandfather has not said anything so far. Although he has no objection, he has not expressed support. If his grandfather does not support him and Wang Xudong together, what should he do.

It is precisely because of such concerns in his heart that Zheng Xiaotong's reaction is so great that the separation is imminent, and Wang Xudong seems to understand. Together.

The two kissed each other and separated for a long time, but Liu Yu was very conscious. He dragged his suitcase and walked away a long time ago. He watched the scenery from the far window, and looked through the glass of the window at a parked park at the airport. a plane.

Zheng Xiaotong said with red eyes: Brother, no matter what, we must be together and never separate, okay?

Wang Xudong nodded firmly and said, Well, no one can separate us. After the New Year, I must come to the capital. I want to propose marriage to the Zheng family, and I want to marry you.

After receiving Wang Xudong's firm answer, Zheng Xiaotong was so moved that he wiped his tears in Wang Xudong's arms and smiled.

Wang Xudong stroked Zheng Xiaotong's hair lightly, and said lovingly, Little fool, the plane is about to take off, come in quickly, and call me when you arrive in the capital.

Well. Zheng Xiaotong nodded.

 …

Lin Yunwen also went through the check-in formalities, because it was still early before the boarding time, Lin Yunwen and Xu Jiaxiang were chatting, and they had not entered the waiting hall for the time being.

Lin Yunwen said: Old Xu, that young man was really strange just now. I don't believe what triple special steel and super stainless steel are. I guess it's just ordinary stainless steel.

Xu Jiaxiang nodded and said, I guess the same is true.

The two chatted, and after a few words, Xu Jiaxiang suddenly seemed to remember something, and after being stunned for a while, he suddenly said: Lao Lin, I remember this triple special steel, I have a friend, Ding Huixian, you You know, he went to this Sanlian Special Steel.

Ding Hui was first a metallurgical expert. Before that, he made a super-strength steel and won the National Science and Technology Progress Award. In addition, Ding Hui was first from Jiangnan Province, and Xu Jiaxiang was also from Jiangnan Province. The two have known each other for a long time and have a good relationship.

A metallurgical expert and a material expert. Metallurgy and materials are closely related from the beginning. Xu Jiaxiang and Ding Huixian have a good relationship. It is completely normal. Not long ago, the two even met for a meal. Ding Huixian said that he went to Sanlian Special Steel. , as the chief expert of Sanlian Iron and Steel, Xu Jiaxiang was surprised at that time.

Now that I think about it, Sanlian Special Steel is the steel company where Ding Huixian served as the chief expert. Suddenly, Xu Jiaxiang was inexplicably excited, and he had a hunch that this super stainless steel is really not easy.

With a slightly excited tone, Xu Jiaxiang said: Lao Lin, hurry up, don't rush back by plane, let's hurry up and find the young man just now, hurry up!

For the recommended ticket 24000 plus more.

That's it for today's update. I'm really tired. I can't stand the high-intensity codewords every day. I hope everyone understands. I still owe you a few chapters, please pay it back later.
