The Rise of Heavy Industry 1980

Zheng De raised his neck and broke out in a layer of cold sweat: "I...... I don't know.

Sun Baoquan complained: "What is this called, our Sanhe Machinery is about to be seen by outsiders!"

Zheng Deju swallowed his saliva, did not make a sound, and said in his heart that I can't be blamed for this

! Wang Chaoyang watched by the heating furnace for a while, called a shirtless worker covered with coal ash, and said: "This master, are you responsible for filling the furnace with coal?"

The worker spoke with a foreign accent: "Yes!".

Wang Chaoyang said: "There is no thermometer on the stove, how do you judge the time of coal filling?"

The worker gritted his teeth and smiled, revealing a mouthful of white teeth: "What does it have to do with the thermometer, anyway, two tons of coal a day, after the filling is completed!"

Wang Chaoyang nodded and said: "Thank you, I know...... Director Zheng, Director Sun, let's go back to the workshop first, I found the problem.

"Found it so quickly?" Sun

Baoquan and Zheng Deju had question marks in their heads, and they could hear the conversation between Wang Chaoyang and the workers, but they were completely unaware of what they were talking about.

However, since Wang Chaoyang said that he had found the answer, the factory director and director had to temporarily suppress their doubts and return to the workshop together.

Back in the workshop, Wang Chaoyang said his thoughts.

The reason for the large number of unqualified parts in the universal milling machine is that the hardness of this batch of semi-finished gears is too high, and the reason for the high hardness is improper control of the heat treatment temperature.

There was no thermometer on the heating stove, which made Wang Chaoyang puzzled, so he deliberately asked the workers to ask. Don't ask if you don't know, you are shocked when you ask, dare to love Sanhe Machinery does not control the temperature, but two tons of coal per day. As for the speed of coal filling, it is up to the workers themselves.

Heat treatment does not depend on the temperature, this is not nonsense! It is

strange that the hardness of the products processed in this way can be stable!

Listening to Wang Chaoyang's words, Sun Baoquan and Zheng Deju were embarrassed together, especially Zheng Deju. Because before that, Zheng Deju boasted that he was proficient in heat treatment technology.

"But...... But I've been doing this before, and there is no problem!" Zheng Deju said as he rubbed his face.

"Then all I can say is that you were lucky. Wang Chaoyang said.

"You just said that you want to control the temperature, but how many degrees do you want to control it?" Zheng Deju regretted after asking, because Wang Chaoyang suddenly cast a strange look.

"Director Zheng, you don't even know the quenching temperature, do you?" asked Wang Chaoyang.

"I...... I really don't know, it used to be all by feeling. Zheng Deju's face was hot.

"Generally, the quenching temperature is about 830 degrees, and then it is quickly reduced to 300 degrees in a water-cooled way, and finally cooled at a natural rate, this is common sense, right?" Wang Chaoyang said.

"This ...... This is the first time I've heard of it. Zheng Deju said.

At the same time, other people around, including the factory director Sun Baoquan, also showed a confused expression.

Seeing this, Wang Chaoyang suddenly realized that he had made the easiest mistake to make by crossing the party. In his opinion, the heat treatment process parameters that are common sense have not been disclosed in this era. In this era, there were many steel mills in the country, communications were not developed, and there was almost no media, so the knowledge that could be casually produced in later generations was still a trade secret in this era!

After being shocked, Sun Baoquan on the other side couldn't help but ask: "Where did you know about the temperature parameters you mentioned just now, I have heard that this specific heat treatment parameter is generally in the hands of large steel mills or large heat treatment plants, big nephew, tell me quickly, how do you know?"

Wang Chaoyang thought for a while and said: "I have a lot of contact with the chief engineer of Changhai Agricultural Machinery and learned from him.

Sun Baoquan suddenly realized: "No wonder this is the case, at the level of Chief Engineer Ma, it is not surprising to know this kind of parameter...... But eldest nephew, can you say the parameters just now, I don't remember ......

" Wang Chaoyang said: "The quenching temperature is 830 degrees, the water cooling is 300 degrees, and then it is naturally cooled."

Sun Baoquan hurriedly rummaged through his pockets, trying to find a note, but found that there was no pen on his body, so he hurriedly ordered Zheng Deju to take notes. The workshop director didn't wait for his instructions, and had already taken out a paper and pen to record.

The two big leaders scrambled to be the first, and the people around them were dumbfounded.

Wang Chaoyang added: "Of course, the temperature I am talking about only refers to

the temperature, different furnace volumes, different steel diameters, the required temperature is not the same, and even if the temperature is the same, the cooling rate is different, the crystalline structure obtained is not the same...... "What is the crystalline structure?"

"You can understand it as the composition of steel...... The hardness varies greatly depending on the composition.

"Oh, write it down, write it down!"

After Wang Chaoyang's explanation, Sun Baoquan and Zheng Deju finally realized how primitive the previous practice was.

Later that day, after the two of them left the Red Star Factory, Sun Baoquan immediately came to Zheng Deju to discuss the transformation of the hot furnace. The thermometer had to be installed as soon as possible, and the workers responsible for filling the coal had to be trained.

Zheng Deju raised his hands in favor of this decision

!"Oh, today's matter, thanks to Wang Chaoyang's help, otherwise how would we know that there is such a big question about heat treatment! Hehe, but we can also be regarded as a blessing in disguise, and when the hot furnace transformation is completed, the quality of our products will definitely be improved!"

"That's right, thanks to Wang Chaoyang!" Zheng Deju also said.

"I didn't expect him to

know so much!" "I know so much, I'm ashamed!"

......

As they spoke, they suddenly fell silent.

Glancing at each other, Zheng Deju said: "Factory director, do you think we need to beware of Wang Chaoyang in the future

?" Sun Baoquan knocked on the table with one finger, took a breath and said: "Why is it not necessary?"

Zheng Deju said: "You see today, we broke a milling machine, a drilling machine, and then the heat treatment workshop also found a major loophole, originally we kept Wang Chaoyang's technology secret and did not let him participate, what was the result?"

As a result, he found out the faults of the milling machine and the drilling machine based on my description alone, and gave important guidance on heat treatment technology, have you thought about these before

?" Sun Baoquan poured himself a cup of hot water while thinking, and asked: "Do you think that Wang Chaoyang has helped us a lot, so we can trust him completely?"

"No.

Zheng Deju said: "I think our so-called 'technical secret' is not as good as bullshit in the eyes of Wang Chaoyang!"

Sun Baoquan swallowed a mouthful of tea foam and coughed.

Santana drove on the way back to the Red Star Factory.

Zhang Miaomiao looked out of the car window and couldn't help humming the song "When Will the Bright Moon Be There". Wang Chaoyang smiled and said, "Are you in a good mood?"

Zhang Miaomiao said.

Zhang Miaomiao was not in a good mood a while ago, on the one hand, because of physical reasons, and on the other hand, because of Sanhe Machinery's attitude towards them, the feeling of being guarded against everywhere was really awkward.

However, everything that happened this afternoon made Zhang Miaomiao feel comfortable...... Although she herself can't tell why.

"Miao Miao, how much do you know about heat treatment?" Wang Chaoyang asked casually.

"It's just scratching the surface. Zhang Miaomiao replied truthfully.

"Oh. Wang Chaoyang nodded and continued to drive.

"......" Zhang Miaomiao looked at him strangely, oh what does it mean? And then there was no follow-up?
