Chapter 246: Laser Quenching
"Master Lu!" Zhu Haifeng just finished eating the big bowl in front of him, took out a handkerchief and wiped the oil on his mouth, and then couldn't wait to say, in fact, this sentence has been wanted to say since Zhu Haifeng entered the house, but when he sat down and didn't wait to speak, the fragrance of the bowl of hot soup noodles that Lu Jiadong hadn't moved his chopsticks before he moved made Zhu Haifeng purse his mouth, although according to his willpower, he could still control his **.
But after all, at noon and night, they used dry food to fool around for a while, and they didn't eat much, so when they smelled the fragrance of hot noodle soup, even if Zhu Haifeng's willpower was strong, his unbearable stomach couldn't be controlled by this willpower, and made a cry of "gurgling~~", Lu Jiadong saw this and quickly asked Liu Liang to cook another bowl of hot noodle soup, and asked to put a few more eggs, but Zhu Haifeng was quite embarrassed and annoyed, and wanted to shirk but was said by Lu Jiadong:
"The body is the capital of the revolution!" After eating a bowl of noodles to his heart's content, Zhu Haifeng's originally pale cheeks also showed a hint of ruddy, which also made Zhu Haifeng more energetic to tell the technical reasons for the failure of the cannon steel:
"I don't think the reason why the cannon steel is not up to par is not in the formula and smelting, but in the heat treatment!"
At this time, Lu Jiadong also finished eating a large bowl of noodles in front of him, and then wiped his mouth, and said in surprise: "Heat treatment?"
"That's right! It's heat treatment!" Zhu Haifeng nodded: "The strength of the cannon steel is not enough, resulting in a decrease in fatigue resistance, since noon, I have inspected the barrel of the gun, and found a total of six cracks, all of which are cracks caused by excessive fatigue of the metal, which can show that the new cannon steel is still lacking in heat treatment processing!"
"I really didn't expect that your point of view is the same as Researcher Qin's!"
"Qin Jingbin also sees it this way?" Listening to Lu Jiadong's words, Zhu Haifeng couldn't help but be stunned, and Lu Jiadong sorted out the materials on the table, and then said to Zhu Haifeng:
"Researcher Qin came to me in the afternoon and said his opinion, which is generally very similar to yours. That is, we still need to improve and strengthen the heat treatment processing technology of cannon steel!"
At the mention of Qin Jingbin, Zhu Haifeng's towering cheekbones couldn't help but tremble, the sudden eyes behind the thick spectacle lenses at the bottom of the bottle flashed a trace of imperceptible embarrassment, and the Adam's apple on his neck moved slightly. stopped again, but finally closed his eyes and asked:
"What did he say!"
"Researcher Qin didn't say much!" Lu Jiadong knew that Zhu Haifeng and Qin Jingbin had serious differences in the processing technology of artillery steel, and now in the face of the difficulties of artillery steel materials, Lu Jiadong hoped that these two material experts could work together. Together, we will completely solve this "roadblock" in front of the new artillery.
Of course, it is not easy to get the two to join hands again, Qin Jingbin is easy to say, after all, his consistent work style is right and not personal, and he is also relatively open-minded, as long as he talks about it, there is no barrier, but Zhu Haifeng is different, not to mention being maverick, and his personality is particularly stubborn.
When he sees something, he rushes forward vigorously, whether it is relatives or friends. Even if he hits a thick wall on the road of sprinting, he may not be able to turn back, but slams his head into the south wall, even if he hits the head and bleeds, he will knock the wall open, and then wipe his bloody face, pointing to the wall and saying triumphantly to the people around him:
"See! Who said this road can't be crossed? I didn't break through today!"
It is precisely because of Zhu Haifeng's maverick personality that his reputation among the new artillery development team is not good, and many leaders of the new artillery leading group have persuaded Lu Jiadong whether to replace Zhu Haifeng after learning about Zhu Haifeng's character. so as not to affect unity.
From noon to night, many members and leaders of the research and development team approached Lu Jiadong and asked him to take advantage of the failure of the development of the gun. completely drove Zhu Haifeng out of the new artillery development team, and even Wang Chuanchen, who did not interfere in this matter, came to Lu Jiadong and asked him to seriously consider this matter!
Lu Jiadong did not have a clear answer to this, from the bottom of Lu Jiadong's heart, he still admires Zhu Haifeng's superb skills and veteran experience, not only Lu Jiadong. Qin Jingbin, who had obvious differences with Zhu Haifeng, also spoke highly of Zhu Haifeng's skills when he talked to Lu Jiadong about Zhu Haifeng in private, and also said that if Zhu Haifeng could change his personality, he would still be willing to cooperate with Zhu Haifeng.
It was Qin Jingbin's attitude that made Lu Jiadong's attitude towards Zhu Haifeng more inclined to stay, so he thought of several sets of persuasion plans for this, just before Zhu Haifeng came, Lu Jiadong was still preparing a draft, thinking about chatting with Zhu Haifeng alone before going back tomorrow, but what he didn't expect was that he hadn't looked for Zhu Haifeng yet, so he took the initiative to find the door.
And Lu Jiadong also took this opportunity to listen to the reasons for the failure of the cannon steel, and at the same time, he also wanted to understand Zhu Haifeng's views and attitudes towards future development, so Lu Jiadong took the initiative to propose Qin Jingbin to see if Zhu Haifeng was still as stubborn and stubborn as before, and the fact is that Zhu Haifeng seemed very calm, although the trace of embarrassment in his eyes was fleeting, but still did not escape Lu Jiadong's eyes, so Lu Jiadong glanced at Zhu Haifeng in front of him, and then took a sip of the teacup in front of him and continued:
"However, researcher Qin still suggests that after going back, we should study and study the heat treatment process, especially in the heat treatment procedure, to see if we can further optimize the treatment!"
"Researcher Qin is right!" Listening to Lu Jiadong's words, Zhu Haifeng sighed sincerely, and then raised his head to look at Lu Jiadong opposite, his eyes suddenly flowed, and in the depths of a trace of embarrassment was an indescribable layer of remorse:
"Chief Master Lu, in fact, I thought of this when I was looking at the artillery, at that time Researcher Qin said that the time interval between austenite, quenching and tempering should not be so long, and now it proves that his point of view is very correct, I relied on my rich experience, I didn't take Researcher Qin's words to heart, plus the stubborn temper that has been difficult to change for so many years! Now I think about it, I really regret it!"
Looking at Zhu Haifeng's remorseful expression and endless emotion, Lu Jiadong knew that this Chief Craftsman Zhu had unconsciously changed because of this failure of the cannon steel, and this change was what he was happy to see, so Lu Jiadong hurriedly struck while the iron was hot, patted Zhu Haifeng's shoulder and continued:
"Chief Craftsman Zhu, let his past be, there is no book that can't be opened, and there is no hurdle that can't be passed, don't you say?"
Lu Jiadong's words made Zhu Haifeng stunned, although he has a stubborn personality, it does not mean that his head is always tendoned, he can naturally hear the deep meaning of Lu Jiadong's words, so Zhu Haifeng's eyes lit up, and then raised his head to look at Lu Jiadong opposite, and said incredibly between his words:
"Master Lu, what do you mean, I can still be with Researcher Qin"
"This should be no problem, I'll go back and do Researcher Qin's work!" Before Zhu Haifeng finished speaking, Lu Jiadong said with a confident smile, but then Lu Jiadong's smile closed, and his eyes looking at Zhu Haifeng became serious and serious:
"Of course, this has to be done by Chief Craftsman Zhu!"
"Yes, willing, I will!" As soon as Lu Jiadong's voice fell, Zhu Haifeng's face showed a unique unnatural smile, and he nodded like garlic and said:
"Researcher Qin's theoretical literacy is very high, I admire it very much, and he is also very strict with technology, and he never gives up easily, which is also very angry with me, not only that, Researcher Qin's Materials Research Institute also has a set of equipment required for our new artillery steel, with it, the development of our new artillery steel will be more effective with half the effort!"
"Equipment, what equipment?" Listening to Zhu Haifeng's words, Lu Jiadong couldn't help but straighten up, and Zhu Haifeng continued: "Laser quenching device!" Saying that, Zhu Haifeng picked up the teacup in front of him, took a sip and continued:
"The six cracks of the sample gun barrel are all in the inner chamber, which has the factor of insufficient strength of the cannon steel, but there are also reasons for the lack of surface hardness of the gun chamber to cause the crack to expand, and the laser quenching device can just carry out surface quenching treatment on the gun chamber to increase the hardness in the gun chamber!"
Listening to Zhu Haifeng's words, Lu Jiadong nodded, the laser quenching device Lu Jiadong had heard of in later generations, it is a widely used vehicle engine cylinder, A surface hardening process for mechanical gear processing, but after all, Lu Jiadong is only a military expert and not a material expert, although he has heard of it but does not understand, he only knows that this process is very advanced and complex, but in his memory, this laser quenching device seems to be only owned by advanced foreign countries, and it seems that he has never heard of it in China, thinking of this, Lu Jiadong couldn't help frowning and looked at Zhu Haifeng and asked puzzledly:
"How could such an advanced device be in the Materials Research Institute? If so, how could I never hear Researcher Qin mention it?"
"I guess even Researcher Qin can't remember himself!" As he spoke, Zhu Haifeng took off his eyes, wiped them with a handkerchief, and then brought them again, and continued:
"In the early years, the country in order to develop long-range launch vehicles need gears with high surface hardness, at that time only the world's most advanced laser quenching technology can be satisfied, but foreign blockade of us, such machinery and equipment can not be introduced at all, so as a supporting project for launch vehicles to develop, a total of four, two of which were damaged and abandoned for various reasons, and the other two completed their mission after completing the gear manufacturing, respectively, to a university in Beijing and the Institute of Materials in South China for scientific research(To be continued.) )
