    After listening to Lin Guanghua's story, Zhuang Jianye couldn't help but be a little surprised. He really didn't expect this guy to have such a miserable life in the second assembly workshop. He should deserve it if he did it well. After all, it was the chief engineer who personally explained it. He should not be taken seriously.  reason.

    If it doesn¡¯t go well, it¡¯s all Lin Guanghua¡¯s responsibility, because the second assembly workshop has said that they lack such talents, so they transferred Lin Guanghua there. If it can¡¯t be the fault of this talent, who else can it be?

    What to do if you can't get it right? It's very simple. Just go to the 23rd Factory. Since you have taken responsibility, you have to bear the consequences. As for the tasks assigned by the chief engineer, just find someone else. Anyway, Yonghong Factory  There are so many college students here, and there are always some who are willing to take the blame.

    Zhuang Jianye really felt a little sympathy for the person in front of him. He wanted to climb up, but the result was great. He suddenly climbed into the fire pit and couldn't get out.

    Seeing that Zhuang Jianye only showed sympathy but said nothing, Lin Guanghua finally became anxious. Zhuang Jianye was the only person in the factory who proposed the brazing process. It was not an exaggeration to say that it was his last life-saving straw. If Zhuang Jianye couldn't help, then he would  He could only pack his bags and go to the 23rd Factory. Just thinking about the educated youth who returned to the city who gave the police a headache, Lin Guanghua only felt that the future was gloomy.

    So he was about to muster the courage to ask again. Just at this moment, he saw the manuscript with several big crosses on the table, and his eyes suddenly lit up and he said, "Are you writing a thesis?"

    Zhuang Jianye nodded: "Yes!"

    Lin Guanghua quickly and mysteriously continued: "My teacher at the university has recently been transferred to the editorial department of the Journal of Aeronautics and Astronautics. We have a good relationship. As long as you help me, I guarantee that your paper will be published as long as it is not out of line."  In Journal of Aeronautics.¡±

    The Journal of Aeronautics and Astronautics is the core journal in the aviation industry. Zhuang Jianye has never published an article in it in his two lifetimes. If not, he wouldn¡¯t have had to wait so long to get ahead in his previous life.

    Unexpectedly, just when he was about to write a paper in this life, someone sent him an invitation from a core journal. Zhuang Jianye said it was a lie if he said he was not interested. You must know that his father-in-law forced him to write a paper and publish it in order to lay the foundation for further promotion and publication in the future.  The greater the publication background of the paper, the stronger the confidence for future promotion.

    But then I thought about it and was quickly rejected by myself, for no other reason than that Yonghong Factory really lacks the application foundation of related processes. After all, the brazing process of aviation products is different from that of general industrial products. Each step is strictly not explained.  , it is also very difficult.

    ¡°It¡¯s okay if you have time to take your time, but only one week is too short, even if you are a god descending to earth, you can¡¯t do it.

    So he shook his head: "The time is too short, and the factory lacks supporting hardware. Really, it's not that I won't help you, I really don't have the conditions."

    When Lin Guanghua heard this, his face instantly turned gray. What Zhuang Jianye said was the truth. The Yonghong factory had never done any brazing process. It used an old-fashioned welding process from the Soviet Union in the late 1950s. The lack of hardware equipment was the biggest limitation. Even if  The theory is so arrogant that it is still unconvincing without practical verification.

    Realizing this, Lin Guanghua finally accepted his fate. Thinking that he would go to the 23rd Factory soon, a sense of sadness filled his heart. He sighed, with a sense of relief, as if he was about to reveal the answer to the mystery.  , asked: "Can you tell me what hardware is needed? Even if I stumble, I still have to figure out where it happened!"

    Zhuang Jianye filled Lin Guanghua's empty teapot with water, and then looked at Lin Guanghua who was still depressed with pity: "Not to mention the vacuum brazing furnace, our factory doesn't have one at all, but it doesn't matter, the provincial welding research institute has one  It¡¯s a small experimental furnace. Anyway, the top of the maze is not big, so it can barely be used. The key is the material!¡±

    Hearing that there was room for replacement of key equipment, Lin Guanghua¡¯s disappointed eyes gradually regained their luster, and he asked hurriedly: ¡°What material?¡±

    "Metal felt!" Zhuang Jianye said.

    Hearing this, Lin Guanghua was startled for a moment, and then asked about the specific situation of the metal felt. Since it was brought to this point, Zhuang Jianye also introduced the situation of the metal felt.

    The so-called metal felt is a material made of metal fibers that are non-woven, laminated and then sintered at high temperature. General metal felt has good filterability and is generally used for polymer filtration, electronic high-temperature gas dust removal, etc.  field.

    However, aviation-grade metal felt is not just for filtration, but an excellent sealing and gasketing material. You must know that due to the unique structure and working environment of jet engines, the materials used must be both durable and lightweight.  Safety must also be ensured.

    Therefore, ordinary gasket sealing materials are not suitable for aerospace engines at all, so people think of using metal felts sintered from durable metal alloys to play this important role. Among them, the most commonly used one is a chromium-nickel ratio between 0.25~0.408.???; alloy metal felt with carbon-nickel ratio between 0.12~0.15.

    This type of metal felt can not only withstand high temperatures of nearly 900 degrees Celsius, but also has a very good sealing effect. Zhuang Jianye has used this material several times in his life, and the effect is very good.

    "It's a pity that this kind of material cannot be produced in China at present. As for the preparation process of the material, it is another technological tree that reaches into the sky. Zhuang Jianye hasn't figured out this one yet, so naturally he can't figure out the others.

    Because of this, even if he clearly wrote down the craftsmanship on the top of the maze in black and white, it would be in vain. It is difficult for a clever woman to make a meal without straw, and without key materials, everything would be in vain.

    That's why, after perfunctory with Chief Engineer He, he avoided the old man and kept silent about the brazing process. He had no choice but to do it. He really didn't have the conditions. If he said it, he wouldn't be able to get it done, and he would be slapped in the face. Why bother?  .

    However, looking at Lin Guanghua's reaction, it seemed that he still didn't give up, with his burning eyes, he looked like he still wanted to give it a try.

    "Are you sure that the composition of that metal felt has a chromium-nickel ratio between 0.25 and 0.408 and a carbon-nickel ratio between 0.12 and 0.15?" Lin Guanghua asked.

    "Yes, what? Do you have it?" Zhuang Jianye asked.

    "I don't, but my wife does!" Lin Guanghua replied.

    Zhuang Jianye didn't say anything this time, but looked at Lin Guanghua in surprise. Lin Guanghua understood and immediately explained. Only then did Zhuang Jianye understand that the No. 10 project that this man's lover participated in had tested many high-performance aviation materials during this period.  They are all rare imported products in China, including the metal felt just mentioned.

    It¡¯s a coincidence that these days Tang Lili often brings information home to catch up on work. Lin Guanghua accidentally saw the situation about metal felt, and even helped his wife calculate a standard constant himself, so he had an impression.

    There is such a coincidence in the world. If you want to sleep, someone will give you a pillow. Zhuang Jianye can't help but be surprised. Don't say anything, just do it.
