Listening to Zhu Haifeng's words, Lu Jiadong couldn't help but nodded, and then a pair of lying silkworm eyebrows squeezed a few times to the middle again, and then asked Zhu Haifeng who was sitting opposite curiously:

"Chief Craftsman Zhu, why is it that Researcher Qin doesn't know about things, but you are so good?"

"In order to tackle the kind of gear with high hardness on long-range launch vehicles, I joined the research and development team with my mentor, and I was fortunate to see and use a laser quenching device!"

Knowing that Zhu Haitao had participated in the development of supporting projects for long-range launch vehicles, Lu Jiadong couldn't help but be in awe: "I really didn't expect that Chief Engineer Zhu also participated in the development of long-range launch vehicles!"

As soon as Lu Jiadong finished speaking, Zhu Haifeng waved his hand: "It's just a supporting project, and the long-range launch vehicle experiment failed at that time, and it was temporarily discontinued, it's all in the past, don't mention it!"

"That's also a great thing" As soon as Zhu Haifeng's voice fell, Lu Jiadong took the conversation, but before Lu Jiadong finished speaking, Zhu Haifeng stretched out his hand to stop Lu Jiadong:

"It's been so long, and it hasn't been successfully developed, so it's not worth mentioning!" As he spoke, Zhu Haifeng took a sip of hot tea from the teacup in front of him, moistened his throat and continued:

"It may also be because of the related projects, so the laser quenching device produced for the manufacture of high hardness gears has lost its application value, the old director of the Institute of Materials at that time knew the value of this device, and wanted to apply for the laser quenching device to be placed in the Institute of Materials for research, and the superior department also agreed to the request of the old director, at that time, because it was a special period, the scientific research environment was not very good, the old director in order to protect this valuable laser quenching device, it was first placed in the equipment warehouse of the Institute of Materials.

Later, the old director died suddenly because of a heart attack, and the research field of the Institute of Materials at this time has gradually shifted from the original metal materials to more advanced synthetic materials, so this laser quenching device has been idle in the Institute of Materials. Not to mention a researcher like Researcher Xiang Qin, who has just been assigned to the Materials Research Institute for a few years!"

After saying this, Zhu Haifeng couldn't help but shake his head self-deprecatingly: "I also checked the cracks in the barrel of the artillery today before I suddenly remembered that there was such a good piece of equipment, otherwise it would be difficult to say if I could remember it!"

"Therefore, the most critical moment is the rich experience of Chief Craftsman Zhu!"

"Chief Master Lu. You've won a prize, me."

"Chief Craftsman Zhu, you are so modest!" Before Zhu Haifeng finished speaking, Lu Jiadong said with a look of reverence: "If you don't have such strong experience and practical experience, even if you see this device, you can't remember it so clearly." It is even more impossible to know the importance of this laser quenching device for the development of artillery!"

Lu Jiadong is right, the science and technology mastered in the field of military production is very important, and rich practical experience in production is even more important, which is like a veteran who has screwed 10,000 screws, no matter what kind of screws he screws, he will immediately think of what kind of tools are more suitable and more labor-saving.

Zhu Haifeng is such a person, because he has rich experience in steel smelting and manufacturing, so when he encounters related problems, he will quickly think of what method should be used to solve it and what equipment to use to deal with it, from this point of view, not ordinary people can do it. Because of this, Lu Jiadong has more reverence for Zhu Haifeng.

And Zhu Haifeng, who has always advocated technology, heard another meaning from Lu Jiadong's praise, and then couldn't help but look at Lu Jiadong with wide eyes:

"Master Lu, do you also know the laser quenching process?"

"I don't know much!" Lu Jiadong said, picking up the thermos on the table, first filling Zhu Haifeng's teacup, then filling his own, and then putting the thermos in its original position and continuing:

"Due to the particularity of the structure of the barrel of the gun, the inner chamber of the barrel is not easy to be quenched by induction heating, but the laser quenching process can achieve this purpose. This process can be used to solve the hardening of the surface of the bore of the barrel, that is, the high-energy laser beam emitted from the laser generator outside the bore is turned by the mirror placed in the bore and quickly irradiated to the surface of the bore of the barrel. As a result, the irradiated part of the gun chamber instantly absorbs light energy, and immediately converts it into heat energy, and the austenite on the surface of the chamber is M in the rise and fall of temperature, so as to achieve the purpose of hindering crack propagation!"

Listening to Lu Jiadong's words, Zhu Haifeng couldn't believe his ears, especially when Lu Jiadong said the sentence "install a mirror in the barrel of the cannon". The whole person couldn't help but be stunned, his sudden eyes suddenly opened and dripped round, if Zhu Haifeng held his breath again at this time, the two eyeballs could burst out, and the tone of his speech became even more incredible:

"Chief Master Lu, you just said that a reflective lens should be placed in the barrel of the gun?"

"Ahh

Lu Jiadong said this from the heart, he is not a material expert, the relevant introduction to laser quenching is also in the later generations to participate in the development of the military industry inadvertently saw the introduction, at that time I saw a lot, but after such a long time, Lu Jiadong can remember only a little bit in his mind, but even if it is such a little words, it makes Zhu Haifeng like a treasure, when Lu Jiadong's voice just fell, Zhu Haifeng couldn't help but pat his thigh fiercely, and shouted excitedly:

"That's right! That's right!" Then Zhu Haifeng's face flashed with excitement, and the corners of his mouth opened lightly, and he said to himself quickly and quickly:

"I didn't think of this method of installing a mirror in the breech, and then reflecting the laser to complete the hardening process in the breech!"

Saying that, Zhu Haifeng raised his head again and said excitedly at Lu Jiadong: "Master Lu, with this method, you can definitely be called an authority in material technology!"

Lu Jiadong was a little surprised by Zhu Haifeng's series of actions, so he asked puzzledly: "Chief Craftsman Zhu, what are you?"

"Chief Master Lu, your sentence of installing a mirror in the barrel of the cannon is really a word to wake up the dreamer!" Before Lu Jiadong finished speaking, the excited Zhu Haifeng couldn't wait to say:

"The laser quenching device is really good, but as Chief Master Lu just said, because of the particularity of the structure in the barrel of the artillery, it is impossible for the laser to illuminate all corners of the chamber, and because the laser is relatively large, it is impossible to irradiate it deep into the body tube seven or eight meters long, so I am thinking about what to use to solve it, and I have also thought of several sets of plans for this, but it is unlikely!"

As he spoke, Zhu Haifeng raised his head again, and his sudden eyes revealed irrepressible admiration: "And this difficult problem that I can't even figure out if I want to break my head has been solved by Chief Master Lu's sentence of installing a reflector in the barrel, just by this sentence, Chief Master Lu is definitely a well-deserved genius!"

"Uh" Listening to Zhu Haifeng's words, Lu Jiadong was very surprised, he didn't expect that he repeated what he saw from the later sources, and even solved the technical problems in the application of the process, so he didn't know what to say for a while, after all, Lu Jiadong couldn't explain the source of these words, but from his heart, he didn't feel how powerful he was, so after contemplating for a while, Lu Jiadong said with a smile:

"Chief Craftsman Zhu is really awarded, I can be regarded as throwing bricks and attracting jade at most"

"No awards, no awards!" Before Lu Jiadong finished speaking, Zhu Haifeng took over the conversation with an excited smile: "If this is called throwing bricks to attract jade, then the brick thrown by Chief Master Lu is also a good jade brick!"

Master Lu, your method is definitely the best solution, although the laser probe of our laser quenching device is not as sophisticated as foreign equipment, but it is definitely enough, as long as we operate it reasonably, the hardening treatment of the inner chamber of the gun is absolutely fine!"

Hearing Zhu Haifeng's words, Lu Jiadong did not spin around throwing any bricks, but said categorically: "Okay! Since this is the case, when I go back tomorrow, I will immediately apply to my superiors to transfer the laser quenching device of the Materials Research Institute to the Hunan Special Steel Plant!"

Lu Jiadong's words are tantamount to a final word, so the people of the new artillery development team left the equipment test team the next day and returned to their respective development posts, and the failed sample gun was also pulled to the warehouse of Wanshan Factory to be sealed, and Lu Jiadong also moved his office to the Hunan Special Steel Plant, personally focusing on the development and production of new artillery steel, and at the same time the relationship between Zhu Haifeng and Qin Jingbin was also as good as ever, and the two began to work together again to tackle key problems in the new artillery steel.

As for the important laser quenching device, it was also applied for by Lu Jiadong, and Wang Chuanchen coordinated from it, and soon issued a document by the Equipment Department of the General Staff Department, which was transferred from the Materials Research Institute to the Hunan Special Steel Plant, so that after two months of hard work, Zhu Haifeng and Qin Jingbin cooperated with each other to improve the manufacturing process of the new gun steel:

In the smelting process, the electroslag remelting process was tried to ensure the utilization rate of the steel ingot and the final purity of the steel; in the forging process, in order to prevent the grain size of the steel ingot from growing and the grain size of the mixed crystal phenomenon of uneven grain size, and to improve the production efficiency, the rotary forging process was used.

In terms of the most critical heat treatment, the austenite, quenching and tempering were optimized, the austenitic, quenching and tempering processes were carried out continuously, and the inner surface of the chamber was hardened by laser technology. )
