The Rise of Heavy Industry 1980

Yang Mingshan's attitude changed 180 degrees, and he not only began to listen patiently to Zhang Miaomiao's plan, but also asked others to sit down.

Sun Baoquan, who had been on the ground before, slowly reacted, got up from the ground, and sat next to Zhao Lichuan tremblingly and asked what happened.

However, Zhao Lichuan didn't have the heart to deal with him, and made a silent gesture to signal him not to interrupt Zhang Miaomiao's words.

At this time, Zhang Miaomiao continued to introduce the improvement plan.

Three of the six types of gears are designed to improve the tooth shape by controlling the amount of deformation in machining, and of course, the amount of deformation control is different for each gear. There are also two kinds of gears with a large number of teeth and large diameters, which need to be processed by a milling machine, and the improvement scheme adopted is to adjust the indexing angle of the tool, and these indexing angles are the optimal solution obtained after the accumulation of countless cardinal data.

There is also a type of gear that is heavy-duty gear, and the difficulty lies in the hardness of the tooth surface. The hardness determines the wear resistance of the gear, and the previous gear hardness of Mikawa Machinery was not up to standard, the wear was serious, and the noise condition was very poor.

By controlling the heat treatment temperature several times, Wang Chaoyang and Zhang Miaomiao found the most suitable modulation parameters, quenching temperature, cooling rate, tempering temperature, ...... Under the control of the latest parameters, the hardness of this heavy-duty gear fully meets the requirements of Longyuan Heavy Industries.

Because he was directly involved in the excavation of the improvement plan, Zhang Miaomiao was very clear about this, and although he was nervous in his mentality, he really entered the technical field, and Zhang Miaomiao's speech gradually became confident.

In the process of Zhang Miaomiao's description of the plan, Yang Mingshan has been listening silently. When Zhang Miaomiao talked about heat treatment parameter control, the quality control director involuntarily moved and asked, "Excuse me, little girl, I'll interrupt."

Zhang Miaomiao said: "You say."

Yang Mingshan said: "You just said that you can control the hardness of heat treatment by adjusting the parameters?"

Zhang Miaomiao nodded.

Yang Mingshan said: "The improvement plans you mentioned earlier are very good, and I am very satisfied. However, regarding the heat treatment parameters...... I am very skeptical!

" Zhang Miaomiao asked: "What do you suspect?"

Yang Mingshan said: "Longyuan Heavy Industry is not my first work unit, I have worked in the Capital Steel Mill before, I know very well what heat treatment is all about, and I know more clearly what heat treatment parameters mean...... Little girl, your improvement plan is very clever, and you yourself are also very good, I don't want you to lie about the heat treatment parameters!"

Zhang Miaomiao shook his head and said, "Director Yang, I didn't lie!" Yang Mingshan's face sank, and said, "I have my judgment if I lie or not!"

Zhang Miaomiao's

face turned red. She can talk about technical issues, but she is not good at arguing about things other than technology.

"Miao Miao, show him the iron-carbon phase diagram. Wang Chaoyang said suddenly.

"Oh yes, I have an iron-carbon phase diagram!" Zhang Miaomiao suddenly realized, and immediately took out a notebook from his small satchel, sandwiched a piece of paper in the middle of the notebook, and after spreading out the paper, the iron-carbon phase diagram was drawn on it.

This iron-carbon phase diagram was originally drawn by Wang Chaoyang, but at first it was just a large frame, and later with the increase of heat treatment data, Zhang Miaomiao added a lot of notes on it, and now on this piece of paper, except for the line chart in the middle, both sides are full of small notes.

"You even have an iron-carbon phase diagram!" This

time, Yang Mingshan couldn't sit still at all. He got up from his seat, leaned forward to look at the picture in Zhang Miaomiao's hand, and didn't speak for a long time, but his breathing became heavier and heavier.

On the side, Zhao Lichuan was also stretching his neck to look at the picture, but he couldn't see the doorway.

As for Sun Baoquan next to Zhao Lichuan, he was also stretching his neck desperately, but he couldn't see clearly from too far away.

But Sun Baoquan's heart was more affected than anyone present. For most of the past half a month, Wang Chaoyang and Zhang Miaomiao have been working under his nose every day, and he has never realized that the two of them have done so many things, and even made a "iron-carbon phase diagram" that even Yang Mingshan was shocked.

"I'm sorry, little girl, I blame you! I suspect you of lying, but you even have an iron-carbon phase diagram in your hand, which proves that you fully understand the principle of heat treatment, you are not lying, it is my villain's heart!"

This move made Zhang Miaomiao at a loss: "Don't say that, it's okay, it's okay.

Yang Mingshan waved his big hand and said: "No, no, if it's wrong, it's wrong, I, Yang Mingshan, still know how to be ashamed!" But now I'm curious, how can you have an iron-carbon phase diagram in your hands, as far as I know, the iron-carbon phase diagram is a confidential document, and people in the steel mill often have a joke that the iron-carbon phase diagram is the 'treasure map' of every steel mill.

Without waiting for Zhang Miaomiao to speak, Wang Chaoyang said: "Director Yang, you are sure to continue chatting, the time has passed for an hour!" "

Oh no, I forgot a very important meeting...... But no matter, I'm more interested in your improvement plan!" Yang Mingshan laughed, and then dialed the internal line and asked the assistant to bring tea in.

Without much effort, Wang Chaoyang and others drank hot tea.

From being yelled at at the beginning of the house, to sitting in the back, to finally drinking hot tea, all this happened in less than an hour.

And in the same hour, Jiang Jialiang outside Yang Mingshan's office was a little restless.

Jiang Jialiang hated Wang Chaoyang very much, but when he deliberately caused Wang Chaoyang to be late, he was a little worried. After all, because of his words, the way of life of a factory is ruined, and no one will be comfortable with this matter.

He has been hiding next to Yang Mingshan's office, according to his experience, Wang Chaoyang and the others will soon be blasted out, he knows Yang Mingshan's temper too well.

But the actual situation was that Yang Mingshan only heard a few roars at the beginning, and then it was quiet inside. Jiang Jialiang didn't dare to get too close, not knowing what was going on inside.

The wait is an hour.

The more Jiang Jialiang waited, the more panicked he became, and when he saw Yang Mingshan's assistant sending hot water inside, he hurriedly went over to ask.

From the mouth of Yang Mingshan's assistant, I learned that Wang Chaoyang and others were still in the office, and Director Yang seemed to be very happy to talk to them.

It

didn't take long for Yang Mingshan's assistant to be called into the office again, and it didn't take long for the assistant to hurry out and find Jiang Jialiang and say, "Jialiang, the director is looking for you, his face is very ugly, you go over quickly!" Jiang Jialiang

broke out in a cold sweat, nodded, and dragged heavy steps into Yang Mingshan's office.

In the office, Yang Mingshan sat behind the desk, and Wang Chaoyang and others sat on the side drinking tea.

After Jiang Jialiang appeared, Yang Mingshan said in a deep voice: "Little Jiang, I asked Zhao Lichuan and them to come to see me at ten o'clock at eleven o'clock, how did you tell them?"
