Siheyuan: Craftsmen of a Great Country

After leaving the laboratory, Jiang Chen went to the training department and the Sangang machine tool production workshop for a tour.

Check the progress of the work, everything is normal.

After that, he went to the factory director's office.

Yang Weimin saw him and smiled: "You're back, kid. Without your factory director, I always feel like something is missing."

Jiang Chen said: "The main reason is that the journey takes too much time, otherwise I should have come back long ago."

Tao Yuan said: "Don't listen to his nonsense, he just wants to wait for the surprise you said years ago."

Jiang Chen said: "No, after looking at the work progress of several departments, I came to find the two leaders."

Yang Weimin said: "Oh, tell me your plan quickly."

Jiang Chen first reported on the division of the laboratory into two groups: applied research and development and theoretical practice.

Yang Weimin nodded after hearing this and said: "Well, it is true that you need to be bold to develop this thing. Just go ahead and do it boldly. As long as you don't poke a hole in the sky, I support it."

After saying that, he pointed upward.

Jiang Chen said: "Then thank the two leaders for their support. Now we may need the help of the two leaders to coordinate the staffing."

Yang Weimin said: "Tell me how many people you want. It's fun."

"Now your laboratory is so popular that all the workers in the factory want to join."

Jiang Chen said: "First of all, I want Bai Jing! Luo Xue has gone to be in charge of the theoretical practice group. Someone must do the data tracking and analysis. Bai Jing has experience, please transfer him over."

Yang Weimin looked at Tao Yuan.

Tao Yuan said: "It's okay to leave Bai Jing to you, but this girl's work at the radio station has just improved recently. If you transfer her away, who will do the work at the radio station?"

Jiang Chen said: "Do you remember Dai Mingzhi? He had a daughter named Dai Fang. After persuasion at that time, she said she would work in the factory after the new year."

"That little girl is educated and has a nice voice. If I think it's possible, I'll transfer her to the radio station."

Dai Ming is a soldier, Dai Mingzhi is a senior worker, and Dai Fang is also educated.

I still have to take care of the niece of my father's old comrade-in-arms when I can.

Of course, if she is really not qualified for the job at the radio station, there is nothing she can do.

Tao Yuan said: "Of course I remember, I also paid special attention to it. If nothing else, the person should be trained in your training department now."

"Well, you tell Chief Wen about this. If Dai Fang can do a good job at the radio station, then Bai Jing will be transferred to the laboratory."

After all, she is his niece, and he also hopes that Bai Jing will have a good future.

Following Jiang Chen definitely has much more potential than staying at the radio station.

Jiang Chen nodded: "Okay!"

Yang Weimin said: "Do you have a direction for the work of this theoretical practice group?"

Jiang Chen said: "Of course, her first mission is to improve the accuracy of machine tools, which is what we call IT tolerance levels. So that our machine tools can perform more precise and precise precision operations."

Yang Weimin said: "What accuracy are you planning to achieve?"

Jiang Chen said: "The first step is to produce machine tools with an accuracy of IT5 to IT6, and then based on it, start researching precision machining and ultra-precision machining machine tools."

The processing accuracy of the most precise ordinary machine tools in the world today is roughly 50 microns, which is between IT10 and IT11.

The accuracy of flower growers' machine tools is even lower. Even the most advanced Sangang machine tools have a processing accuracy of only 0.1 mm, which is 100 microns.

It is enough for ordinary use, but if it requires close processing, he is not yet able to complete it.

And Jiang Chen’s goal is 5 microns.

This was an accuracy that would only be achieved almost thirty years later.

It’s a goal anyway, so you might as well set the goal a little higher. As for the final accuracy that can be achieved, it depends on the entire system.

But what he could do in such a small area of ​​​​the country in a small day, he didn't believe in the flower growers with such a large land and abundant resources, and he couldn't do it even with his own cheating device.

Yang Weimin said: "Your goal is indeed long-term."

Jiang Chen said: "It all depends on people. At least there is a direction and a goal. It is better than a headless fly running around everywhere."

Yang Weimin nodded: "Just do it, things will work out."

"But this is all led by Luo Xue. Isn't she under too much pressure? Do you want the Ministry of Industry to help find help?"

Jiang Chen thought for a while and said, "Actually, I also think it's best to find helpers, but I'm afraid that the people who come here will rely on their status and be self-centered in everything, which will affect our progress."

"So, I want to let Luo Xue give it a try in the early stage, and then consider foreign aid when she reaches her limit or cannot produce results."

Yang Weimin nodded: "That's okay, try it yourself first."

Jiang Chen said: "However, the theoretical practice team here needs a few down-to-earth workers who can control the precision of parts processing. We may need to ask Factory Director Yang to arrange this."

"The number of people doesn't need to be large, just one for each type of work."

Yang Weimin said: "As for the fitter, Yi Zhonghai, what do you think?"

During the New Year's Eve dinner, Yi Zhonghai came in and asked Jiang Chen to go out to communicate.

He didn't know what the relationship between the two was, so he made a special trip to ask the doctor.

If the relationship is good, Jiang Chen will definitely agree to transfer Yi Zhonghai into the laboratory.

After all, Yi Zhonghai is also an eighth-level worker, so there is no technical problem.

Jiang Chen shook his head: "He can't do it. Maybe his skills are good, but the burden is heavy and he is not suitable for the R&D department that requires a higher degree of freedom."

Yang Weimin understood clearly: "Okay, I will solve the personnel problem."

Tao Yuan didn't understand some professional terms, so he listened quietly and didn't speak.

Jiang Chen said: "Representative Tao, there are still things going on here and I may need your help."

Tao Yuan said: "Whatever it is, just say no."

Jiang Chen carefully took out two bottles of water from his hometown from his bag.

Three question marks appeared on both Yang Weimin and Tao Yuanyuan. What are you doing with the water?

Or maybe the clear liquid in the bottle is wine?

But looking at Jiang Chen's cautious look, they all knew that the thing inside was definitely not simple.

Jiang Chen carefully handed the water to Tao Yuan: "Representative Tao, please find two reliable institutions to conduct trace element testing on the water in the bottle."

“The more authoritative and accurate it is, the better.”

Tao Yuan also carefully took the water: "What are you doing?"

Jiang Chen said: "My cousin is making steel in my hometown, and I accidentally heard from him that the quality of the steel made in my hometown is far superior to ordinary steel, and the hardness is extremely high."

"I went to the site for a day and talked with them. I felt that the reason why the quality of steel is so good is most likely due to this water."

"So I brought two bottles of water out for testing. If the root cause is found, it may be of great help to our steel research."

Tao Yuan asked tentatively: "You mean to solve the problem of substandard steel quality in the Ministry of Industry?"

Jiang Chen shook his head: "No, I mean, special alloy steel."

bump.

Yang Weimin slapped the table and stood up: "What? Special alloy steel?"

Clearly, he knew the value.

Special steel means high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties.

It allows steel to be applied to more scenes and perform better.

Alloy steel can be said to be a qualitative improvement in the application of steel.

Although flower growers began to develop alloy steel in 52 and produced the first batch of high-temperature alloy steel in 56, there were no other gains.

Even the bridge panels will not be produced until four years later.

So, now that he heard that Jiang Chen might have a breakthrough in special alloy steel, he was of course excited.

If something can be gained, its impact and substantive effect will even be greater than the successful development of Sangang machine tools.

Jiang Chen nodded: "Yes."

Yang Weimin turned to Tao Yuan and said eagerly: "Old Tao, go and do this right now and ask Xiao Yang to drive you there."

Tao Yuan said: "Okay, I'll go right away!"

Tao Yuan also realized the significance of alloy steel and immediately turned around and left.

Jiang Chen stopped Tao Yuan: "There is one more thing. It is suspected that there are mineral deposits in my hometown. I can tell you about it too."

At first, Jiang Chen was not prepared to talk about this, because once the mining started, it would mean pollution and the environment in his hometown would further deteriorate.

But what he could think of, others could also think of, so he simply said it.

Jiang Chen said again: "By the way, Representative Tao, can you ask the Ministry of Industry to open a letter of introduction for me? I may go there later."
