    ¡°Yeah~~~¡±

    After looking at it carefully for a while, the middle-aged man opened his eyes and squinted again, crossed his arms over his chest, and shook his round head: "No~~ It's not the precision casting process, but! The most important mold in the precision casting process  Manufacturing method, and it is also a new method of manufacturing precision casting molds.¡±

    The middle-aged man became more and more frightened as he read. Although there were only a few paragraphs written on the paper and they were not coherent, he could tell at a glance what Zhuang Jianye was doing with his technical skills. But because of this, he was very strange.  , because what Zhuang Jianye wrote was not at all the manufacturing method of Yonghong Factory¡¯s existing turbine orientator precision casting mold, but a brand-new production plan.

    And the ideas and data seem reasonable.

    This surprised him a bit. As the heat-receiving component of an aero-engine, second only to the turbine blades, the turbine orienter has a very harsh working environment. Because of this, its production and manufacturing has always been a difficult problem in aero-engine manufacturing.

    Let alone making a new mold method, it is not easy to fully understand the old mold production process.

    The second general assembly shop is well-known in China for its excellent precision casting technology. One of the two is that the second general assembly shop has unique experience in precision casting molds for turbine orientators. But behind the glory, the second general assembly shop has  The second workshop has been exploring continuously for ten years to achieve today's results.

    It can be seen how difficult this type of precision casting mold is to master.

    The problem is that the second assembly shop still uses mature technology, while Zhuang Jianye has designed a brand-new precision casting mold, and it seems to be making good progress. The difficulty and hardship are simply different.

    So he looked at Zhuang Jianye, who ignored his surprise and kept leaning on the table to write, and asked: "Little comrade, did you make the mold for the turbine orienter yourself?"

    "I wanted to be with someone else, but it's a pity that there is no one, so I have to do it by myself!" Zhuang Jianye was very annoyed with this guy who was yelling next to him. He recognized him when he recognized him, so why did he call him out? He almost scared himself  It interrupted my train of thought, so I said it in a rude way.

    The middle-aged man didn't pay attention to the thorn in Zhuang Jianye's words. Instead, he pulled a chair from the side and sat down politely. He looked at what Zhuang Jianye had just written and continued to ask like a curious baby: "You  Is this a water-soluble living block forming method?¡±

    Zhuang Jianye finally understood that the guy next to him was not looking for information, but was deliberately causing trouble. With such a person chattering next to him, he couldn't feel at ease at all. He simply put down his pen and turned to look at the middle-aged man: "No.  Wrong, it¡¯s the water-soluble moving block forming method.¡±

    "I remember that our factory used a single blade wax mold and a plate combination method. Yours seems to be different from the one in the factory." The middle-aged man looked at Zhuang Jianye in confusion.

    Zhuang Jianye blushed slightly, thinking that this guy is still an expert. He has messed up the technical documents. He knows what methods are used in the factory. Now he can't help but feel a little embarrassed when he meets an expert.

    But he couldn't admit that he had messed up the manuscript documents. If Director Yan and the others found out, he would have to knead himself into a ball. So Zhuang Jianye quickly adjusted his state, his face not red, his heart not beating.  He looked at the middle-aged man until he felt a little scared. He touched his fat round face and asked, "What's wrong? What's the problem?"

    "Don't you think it's difficult to control the accuracy of the turbine orienter manufactured using the factory's method?"

    The middle-aged man didn¡¯t expect that Zhuang Jianye would ask him such a question after looking at him for a long time. He didn¡¯t know how to answer it, and Zhuang Jianye was not prepared to give the middle-aged man a chance to speak.

    He felt very guilty and could not give the initiative to others, so he immediately continued after saying one sentence: "The answer is obvious, it must be difficult to grasp, because among the two methods, the single blade wax model and the disk combination method,  Whether it is the combination of pressed grinding tools or the welding combination, both require complex large-scale fixtures, which are not only difficult to operate, but also require frequent replacement of component positions. How to maintain accuracy in such a difficult operation?"

    "This" The middle-aged man frowned and was about to speak, but Zhuang Jianye reached out to stop him and continued: "I know you want to say that using the steel body moving block method, the accuracy will be more guaranteed? Yes, the United States  Many aviation manufacturing companies use this method. The problem is that the United States has deep pockets and can afford the high cost of steel body moving blocks. Our factory has a weak foundation and few resources. This kind of mold is 4 times more expensive than other molds.  , and the method that takes a long time is simply not practical for our factory.¡±

    As he spoke, Zhuang Jianye took a long breath, with a look of compassion on his face, and continued: "So after much thought, the water-soluble living block molding method is good. While the molding accuracy is guaranteed, the cost is also low.  High, more importantly, the complex large-scale fixture link is removed, which greatly improves the efficiency.It reduces the manufacturing difficulty and is very suitable for use in our factory.  "

    After saying such a long series of words, Zhuang Jianye also felt a little thirsty. He picked up the teapot on one side and took a sip of water. Seeing this, the middle-aged man finally took the opportunity to speak: "It seems that you are very good at precision casting of turbine orientators."  There is research.¡±

    "It's not bad. I majored in aircraft power engineering in college, and I've specialized in research on turbine directional devices. Let me tell you, this turbine directional device is very important. If the primary and secondary turbines didn't have these things, the airflow would be impossible.  It cannot be smoothly introduced backwards, but because of this, the working environment of the orienter is very harsh and the requirements for components are very high. Fortunately, it is fixed on the turbine shaft, unlike the blades, which have to move at high speed.  High-speed centrifugal force, so the difficulty is slightly lower"

    After drinking the water, Zhuang Jianye felt like he was resurrected with full health. He started to popularize the basic knowledge of turbine directional control. He looked like he had been holding back for countless years and finally found a close friend to talk to. He couldn't stop talking.

    In fact, Zhuang Jianye¡¯s idea is very simple. Get this guy away quickly, so as not to ask questions here and find out his own flaws, which will be ruined.

    "It turns out that the middle-aged man next to him was more patient than him and listened to the call with gusto. He even poured himself a glass of water and listened while drinking, as if it was like listening to a storytelling. It was so comfortable and enjoyable.

    Zhuang Jianye was convinced that he could listen to such boring things, but that was it, because he could already get off work, so he looked up at the clock on the wall and smiled apologetically: "Sorry  , it¡¯s time to get off work. Have you found your information? If not, please come back after work in the afternoon.¡±

    This was the expulsion order. The middle-aged man looked a little disappointed. He stood up and adjusted his old Chinese tunic suit. He nodded politely: "Okay, I'll come back in the afternoon." After saying that, he walked towards the door.  Suddenly he remembered something, turned around and asked Zhuang Jianye: "Little comrade, I haven't asked you what your name is yet."

    "Zhuang Jianye!" Zhuang Jianye replied, walked out of the archives room, turned around and locked the door. The middle-aged man standing on one side looked at Zhuang Jianye up and down in surprise, as if he was recognizing Zhuang Jianye again: "Are you Zhuang Jianye?"
