Chapter 226: Hurry to find Wang Xudong

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 aviation motivation. ΔFiction
As a senior expert in the field of China Aviation Motivation, Lin Yunwen is presiding over the development of a national key type of aviation motive. At present, he has encountered major difficulties, and also major difficulties in materials.
The progress of this aeronautical motive at the beginning is still good. Not only has the design been successfully completed, but also the trial production of a verification machine has been completed. This verification machine has also been tested on the test bench. However, from the perspective of the test run, it is not not ideal.
After careful analysis by the entire scientific research team, the problem was not in the design, nor in the manufacturing process, but in the material. The materials were not good enough, and almost all the verification tests failed.
With this time his friend Xu Jiaxiang’s birthday, Lin Yunwen took the time to come and congratulate Xu Jiaxiang on his 50th birthday. On the other hand, and most importantly, Lin Yunwen wanted to seek Xu Jiaxiang’s help.
Regrettably, when Lin Yunwen explained the situation, Xu Jiaxiang also felt very mind-boggling and helpless. This is a key model of aviation motives, and the requirements for materials are very demanding. Even Xu Jiaxiang has no way to solve this material problem.
Lin Yunwen was full of disappointment in his heart, and now he is slightly depressed. He is about to leave Jiangnan Province and continue his own research after returning. Lin Yunwen even has such a plan. It is impossible to solve the material problem, so he can only change the design structure and lower the requirements. But in this case, the overall performance of this aviation motive will drop a lot.
Helpless, there is no way, it seems that the overall performance of the aviation motive can only be sacrificed, Lin Yunwen thought so frustrated in his heart.
Wang Xudong heard the content of the chat between the two clearly. Wang Xudong turned around and looked at the two men curiously. Wang Xudong saw that Xu Jiaxiang patted Lin Yunwen's shoulder lightly, which was comforting, and then lightly. Sigh lightly.
Wang Xudong was moved in his heart. He is one of the shareholders of Sanlian Special Steel. Although he stands behind the scenes, if he can attract customers for Sanlian Special Steel, especially military customers like this, if the special steel of Sanlian Special Steel can be used by the military. It’s a great thing to use the side procurement to military products.
Eight or nine out of ten domestic aviation motives are used by the military. That is to say, if Sanlian Special Steel's special steel can be used on aviation motives, the most important user is the military.
Wang Xudong wanted to say loudly, I can solve your problems, but Wang Xudong knew that if he really said that, if the other party didn't believe it or not, he might think he was a lunatic.
Knowing this in his heart, Wang Xudong is very particular about strategy, with a friendly smile on his face, looked at the two of them, and accosted: "You are experts, please ask first, we are not in a hurry."
There are a lot of people going through the check-in procedures, and Wang Xudong’s team has several people in line. Lin Yunwen and Xu Jiaxiang are just behind Wang Xudong.
Lin Yunwen said: "Young man, it doesn't matter, come first, then come first, let's go first."
Wang Xudong had a good impression of Lin Yunwen and Xu Jiaxiang. They 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 about it, they only mentioned key models, aviation motives, troubles and other words. They never mentioned materials. Aviation Motivation model, verification test details, etc.
However, Wang Xudong guessed that the two people estimated that it was due to material difficulties. Sanlian Special Steel should immediately open the furnace to smelt the first furnace of stainless steel. Wang Xudong wanted to sell it to the two.
Wang Xudong was really straight.
Wang Xudong said: "Two, Sanlian Special Steel Group in Wujiang City is about to smelt the world's most advanced stainless steel. This is a very remarkable stainless steel material. It is not only absolutely first-class in corrosion resistance, but also has good mechanical processing. Performance, strong mechanical structure strength, I wonder if you two are not interested?"
Lin Yunwen's eyes lit up, but soon his eyes dimmed, and he sighed slightly, thinking in his heart, Sanlian Special Steel, I have never heard of it. I guess this so-called grade stainless steel is not much better, so I don’t want it. Hope.
For the aviation motive that Lin Yunwen presided over, there are two major material problems encountered, one of which is the stainless steel material problem.
Generally speaking, titanium alloy materials are widely used in the compressor part of aviation motives, because this material is corrosion resistant, small in specific gravity, light in material, and high in mechanical strength. It is the material of choice for cold parts like compressors.
But titanium alloy is not perfect. It has a fatal flaw, that is, it is not resistant to high temperatures. To improve the overall performance of this aircraft motive, the compression ratio must be increased in the design. The compression ratio is high, and the compressor is level one level. As the compressed air in the compressor is compressed level by level, the temperature also rises level by level. The temperature at the back of the compressor has reached a few hundred degrees. After the limit of titanium alloy, it must be Use stainless steel material.
High-quality stainless steel materials are also corrosion resistant and have good mechanical strength. The only point is that the specific gravity is higher. In order to increase the compression ratio and improve the overall performance of the motive, although the stainless steel material has a greater specificity, it is compared with the overall performance improvement. It is totally worth it.
Of course, the material problem encountered by this new type of aviation motive is not only stainless steel, but also a high-temperature material that has also encountered problems, but if any of them can be solved, it is definitely a huge surprise for Lin Yunwen.
It is a pity that Lin Yunwen did not believe that, at all, he did not 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 aviation motivation.
Lin Yunwen knows the harshness of materials for aviation motives, especially advanced aviation motives.
Seeing Lin Yunwen's unbelief, Wang Xudong just shook his head and didn't continue the conversation. Wang Xudong's meaning was obvious. I have given you the opportunity. If you did not believe it, you lost this opportunity. That is your own problem.
"Brother Dong, it's our turn."
Liu Yu yelled in front, Wang Xudong smiled, and did not talk to Lin Yunwen anymore, but took a few steps forward and began to help Zheng Xiaotong check in, got the boarding pass, and the three of them walked towards the waiting hall. .
When he walked to the gate of the waiting hall, Zheng Xiaotong was obviously disheartened, because he was about to be separated, and Zheng Xiaotong would return to the capital. It would take at least a week for the two to see each other again.
"Brother Dong..."
Zheng Xiaotong's eyes suddenly turned red, and big tears were about to flow down. Wang Xudong was very distressed with a pitiful look.
Wang Xudong gently hugged Zheng Xiaotong and kissed Zheng Xiaotong's forehead gently. Where did he know that Zheng Xiaotong reacted greatly, and he took the initiative to kiss Wang Xudong.
There are a lot of people at the airport. If it is normal, according to Zheng Xiaotong’s personality, he would definitely not take the initiative to kiss Wang Xudong in such a place, but he thinks that he will be returning to the capital soon. After returning, I still don’t know what the family’s future marriage is like. Attitude, whether to accept Wang Xudong or not, Zheng Xiaotong had 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 did not like Wang Xudong. In addition, the Zheng family was such a big family, unlike ordinary people, the attitude of others.
More importantly, Zheng Xiaotong also knows that his grandfather has not said anything to this day. Although he has no objection, he has not said that he supports it. What should he do if his grandfather does not support himself and Wang Xudong.
It is precisely because of the various worries in his heart that the difference is imminent, Zheng Xiaotong’s reaction is so great, Wang Xudong seems to understand, he is moved in his heart, secretly said, no matter how much resistance he encounters, he must be Xiaotong. together.
The two kissed together, and they separated for a long time. Liu Yu was very conscious. He dragged his suitcase and walked a long time ago. He looked at the scenery from a distant window and looked at the parked person at the airport through the glass of the window. An airplane.
Zheng Xiaotong said with red eyes: "Brother Dong, 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 Chinese New Year, I must come to Beijing. I want to propose to the Zheng family and I want to marry you."
After receiving Wang Xudong's firm answer, Zheng Xiaotong was moved to a complete mess. In Wang Xudong's arms, he wiped his tears and smiled.
Wang Xudong gently touched Zheng Xiaotong's show, and said affectionately: "Little fool, the plane is about to take off, you can go in, when you arrive in Beijing, call me."
"Yeah." Zheng Xiaotong nodded.
………
Lin Yunwen also went through the boarding procedures, because it was still too early to board the flight, Lin Yunwen and Xu Jiaxiang were chatting, and they have not yet entered the waiting hall.
Lin Yunwen said: "Old Xu, the young man was really strange just now. I didn't believe it about triple special steel and what grade stainless steel. I guess it's just ordinary stainless steel.
Xu Jiaxiang nodded and said, "I guess so."
The two chatted. After chatting for a few words, Xu Jiaxiang suddenly thought of something. After being stunned, he suddenly said: "Lao Lin, I remember this triplet 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~EbookFREE.me~ before he also produced a strong steel, which 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 had known each other a long time ago. And the relationship is pretty good.
A metallurgical expert and a material expert. Metallurgy and materials have a close relationship. Xu Jiaxiang and Ding Huixian have a good relationship. Not long ago, the two even met for a meal. Ding Huixian said that he had gone to Sanlian Special Steel. At that time, Xu Jiaxiang was also taken aback as the Xi expert of Sanlian Iron & Steel.
Now that I think about it, Sanlian Special Steel is the steel company where Ding Huixian served as the expert. Suddenly, Xu Jiaxiang was inexplicably excited, and he had a hunch that this grade of stainless steel is really not easy.
With a slightly excited tone, Xu Jiaxiang said: "Old Lin, hurry, don't rush back by plane, let's go find the young man just now, hurry!"
