Siheyuan: Craftsmen of a Great Country

After chatting with Lu Yuehua, Jiang Chen went to see the construction status of the top injection converter.

The furnace body with a capacity of 200 tons has been refined by Shijingshan Steelmaking Plant and shipped here.

Other required materials are basically in place.

The construction work is also going extremely smoothly, and it is expected that the experiment of converter steelmaking will be officially started next week.

That is to say, there are fewer workers responsible for construction, otherwise the speed will be faster.

After seeing all this, Jiang Chen came to the logistics office.

Personnel from the application R&D department are conducting the final quality inspection of Sansteel machine tool parts.

It is expected that they will be able to complete testing of all parts today.

Everyone saw Jiang Chen and stood up to say hello.

Jiang Chen waved his hand: "Comrade Qin Kai, what are the results of the quality inspection?"

Qin Kai smiled and said: "Director Jiang, the quality of the overall parts is still good, and the compliance rate is above 98%."

"Especially the spare parts produced by Shuchuan Steel Rolling Plant, the parameters far exceed the standards, and the pass rate is 100%."

"Only two manufacturers produce parts with a low qualification rate."

Jiang Chen was stunned: "Oh? How low is it?"

In fact, Liu Yue had already told him the result, but he didn't show it.

After all, Qin Kai is the leader of this application research and development team.

Qin Kai said: "The screws produced by Sanqin Steel Rolling Plant are generally shoddy, with extremely poor workmanship and poor precision. The pass rate is less than 10%."

"The parts produced by the Fourth Machine Tool Factory in Sijiucheng have no problem with the workmanship, but the quality of the steel is too poor and all the parts are substandard."

Jiang Chen said: "How could it be so bad?"

Qin Kai said: "The production technology of Sanqin Steel Rolling Mill may be too backward, coupled with the insufficient level of workers, which resulted in such a result. Of course, it may also be that they did not take the production of these parts seriously at all and made random production. Cross-fertilization.”

"As for the No. 4 Machine Tool Factory, it's just that the quality of the steel is poor."

Jiang Chen nodded: "Okay, I understand. Fortunately, we find different manufacturers to produce each component, otherwise the assembly and production of Sangang machine tools will be greatly affected."

When assigning tasks, both Zhou Xinjian and Jiang Chen agreed that eggs should not be put in one basket.

Especially the production of these first few batches of Sangang machine tools.

Therefore, they found multiple manufacturers to produce each part, and the number of overall parts far exceeded the plan.

The purpose is to cast stones to ask for directions, and through this preliminary production, select the final manufacturer of fixed parts.

Others who are unqualified and have low compliance rates will be excluded from the plan and will no longer be allowed to participate in the production of Sansteel machine tool spare parts.

Survival of the fittest is a natural law, but this will need to be done more secretly.

Jiang Chen nodded: "Okay, let's call everyone for a meeting. I'll tell you about everyone's research topics in the next few days."

Qin Kai was delighted: "Is there a new topic?"

Jiang Chen shook his head: "It's not a new subject, it's just about making our children better."

Soon, everyone gathered together: "Everyone has worked hard during this period."

"But your hard work is worth it, because your efforts will make our Sangang machine tools a guarantee of quality and a living brand for flower growers."

"Now, I have a new idea that can make our machine tools more flexible and controllable."

Then, Jiang Chen came up with the idea of ​​a gearbox.

Qin Kai slapped his thigh: "This idea of ​​a gearbox is great! It just so happens that we still have an empty space on the main shaft, which is perfect for installing the gearbox."

At first, the machine tool was running too fast, and it was Liu Yue who suggested changing the gear size to adjust it.

Now Jiang Chen has proposed the idea of ​​a gearbox on this basis to make the machine tool more maneuverable and adapt to different speeds according to the proficiency and needs of different people.

Moreover, the principle of the gearbox is very simple, and the production and control are not complicated.

In fact, gearboxes are used in many places. Machine tools with gearboxes appeared internationally fifty years ago.

It’s just that the flower growers’ previous machine tools had a single function and were not equipped with gearboxes.

Qin Kai suddenly came to his senses: "Wait a minute, why is there exactly a position on the main axis? Did Director Jiang have this idea for a long time?"

Jiang Chen smiled and said: "The space reserved at that time was not reserved specifically for the gearbox, but reserved for new functions."

"Now it's perfect for installing the gearbox."

Qin Kai said: "Sure, after we finish testing the spare parts today, we will start configuring the gearbox for the Sangang machine tool."

Jiang Chen nodded: "Okay, it is expected that starting from next Monday, Sangang machine tools will be officially assembled and put into production, so try to complete the installation and testing of the gearbox within next week."

Qin Kai smiled and said: "Don't worry, Director Jiang, it won't take that long."

Jiang Chen added: "By the way, our new Sangang machine tool may use cutting tools made of the latest alloy steel, which will have a longer service life and higher precision."

"As long as everyone knows this, I don't know when the first batch of knives will be produced."

It takes time for alloy steel to be successfully developed and put into production, and it also takes time to turn it into cutting tools after production.

Since No. 3 Steel Factory has no plans to produce knives, Jiang Chen is not sure when the real knives will be released.

But sooner or later I will definitely have to change to a better tool.

In the afternoon, Zhang Cui and Zhang Huajun arrived at the No. 3 Steel Plant, but the security guard prevented them from entering and asked Jiang Chen to pick them up in person.

After Qi Fei left, the Ministry of Industry hired a new man named Chen Yuqin to be the director of the security department.

It is said that this person retired from the army and was meticulous in his work.

After he arrived, the security work of the security office improved visibly.

Everyone entering the factory must verify their work permit or other relevant certificates.

If a worker forgets to bring relevant documents, he must find a leader above the director level to guide him before he can enter the factory.

Except for those on duty, other security guards are scattered around the factory patrolling. If there is any suspicious behavior, security guards will come up for questioning every minute.

Regarding these changes, the factory leaders and Jiang Chen were quite happy to see them.

At least the safety factor of the factory has been improved.

Lao Yang's body and bones are getting worse day by day, and he cannot withstand too much fright and torture.

Jiang Chen was not worried that another Liang Yue would directly attack him openly, lest the three of them become tigers.

Of course, the security of the laboratory is still managed by the army.

No matter at any time, that touch of green is the most reassuring.

As for Liang Yue, even if the security department changed its leadership, it was still investigating.

But this college student, who was usually pampered and had a negative ability to survive in the wild, completely disappeared from everyone's eyes, and no trace could be traced.

This surprised Chen Yutan and the public security officers responsible for the case.

Jiang Chen picked up his mother and cousin and went to the open space designated for him in the factory.
