Chapter 157: Exciting news from Shougang
Soon, the group arrived at Shougang.
This is not the first time Jiang Hui has come to this place.
But the last time I came here was for car repairs. I didn’t go around the factory, and I didn’t have the opportunity to visit the production site.
This time it was different. After registering at the door, someone took them directly to the conference room. They met Zou Yuan and the others first, and at the same time got to know the chief engineer and director of the technical department of Shougang. and other related personnel.
"Let me briefly introduce to you the progress of the high-strength automotive steel plate project so far."
Although Shougang is the home team, Zou Yuan is the specific person in charge of the project.
He will definitely not give up control of the project easily, otherwise when the time comes to reward based on merit, the first credit will not be his.
Of course, if we really want to explain in detail whose credit it was, it might not be Zou Yuan’s, because the original idea was proposed to him by Zhu Jiansheng and Jiang Hui.
When writing relevant reports, Zou Yuan also wrote the names of Zhu Jiansheng and Jiang Hui side by side behind his own.
It is equivalent to being the joint first author in the paper.
This operation is quite conscientious.
“Last year, Professor Zhu from Capital Institute of Technology and Jiang Hui from Capital Automobile Manufacturing Plant came to me and wanted to find a production solution for high-strength automotive steel plates for the new BJ212...”
< br>Zou Yuan glanced around and began his explanation.
In terms of the main processing technology of steel, there are not many changes. After all, this is a relatively mature technology. If you want to change it, you will have to make major changes to the equipment.
However, in terms of specific process parameter settings, some adjustments have been made in many places.
Especially in terms of the ratio of various materials, a lot of adjustments have been made.
Don't think it's just a matter of simply adjusting the ratio of raw materials, but in actual production you need to know what the adjustment will look like, but it requires a lot of experiments.
Why many companies are reluctant to engage in basic materials science is because this field requires large investment, but the output may not be large or even productive.
The fact that Zou Yuan and Shougang's team were able to produce results so quickly has a lot to do with the fact that the materials Jiang Hui provided before contained a lot of specific information.
This kind of "pull a seedling to encourage growth" method is absolutely effective.
“Don’t worry, everyone, our Shougang Group is now applying to the Ministry of Metallurgy to become the first batch of demonstration factories for factory operation reform.”
“This matter was first raised by the Capital Automobile Manufacturing Plant. . ”
“At that time, we will definitely promote high-strength automotive steel plates, which are very profitable products, and we will not delay everyone’s work. ”
As Shougang. Chief Engineer Zuo Guangsheng must stand up and speak at this time.
After all, the technology is actually in the hands of Zou Yuan, and Shougang is also cooperating with the development. There are some key things that they have not yet fully understood.
In this case, if Zou Yuan wants to find other steel manufacturers to cooperate, then Shougang will suffer huge losses.
Although China's industrial level at this time was not particularly high, the categories were actually very complete, and many steel plants were built as key projects.
The construction of Baosteel in Shanghai is also in full swing. In a short period of time, domestic low-end steel production capacity is actually a bit excessive.
This situation will not change until a few years later, when all walks of life begin to develop vigorously.
Even if history remains unchanged, the Ministry of Metallurgy will require domestic steel mills to reduce part of their backward production capacity in the next two years.
In this case, Shougang definitely wants to hold a good product like high-strength automotive steel plate in its own hands.
"Chief Engineer Zuo, the high-strength automobile steel plate we jointly developed will be reported to the ministry soon. By then, major steel plants such as Anshan Iron and Steel, Maanshan Iron and Steel, and Wuhan Iron and Steel will definitely get the news soon. . ”
“If we cannot quickly launch this product and provide it to various OEMs, it is inevitable that there will be some other ideas within the department.”
“Especially Anshan Iron and Steel Co., Ltd. At least most of the domestic automotive steel plates are produced by them.”
Although Zuo Guangsheng has already made a promise, Zou Yuan will definitely put some pressure on him with such a good opportunity.
After all, he very much hopes that this product can be used in cars as soon as possible, which is also very meaningful to him.
Maybe with his achievements in high-strength automotive steel plates, he can successfully become the head of the Department of Iron and Steel Metallurgy.
Some time ago, old classmate Zhu Jiansheng became the director of the Vehicle Engineering Department of Capital Institute of Technology, and he was also a bit jealous.
“The steel used most in cars is mainly coiled plates, which are relatively convenient to transport.”
“Whether we transport it to Chuncheng or Shanghai after production, it is actually possible.”
“There is absolutely no need for Anshan Iron and Steel to produce high-strength automotive steel plates.”
“ We will also report this to the ministry in the future.”
Zuo Guangsheng also felt a little pressure.
Some time ago, he did not pay special attention to this project. He felt that the projects jointly conducted by professors from Capital Iron and Steel Institute and Shougang must be scientific research in nature and often have nothing to do with actual mass production.
At least judging from some past cooperation, this is basically what it looks like.
Real steel product research and development still has to rely on Shougang itself, or introduce technology from overseas.
Unexpectedly, in just half a year, Zou Yuan would cooperate with some technical staff of Shougang to launch a satellite.
Advanced steel materials such as high-strength automotive steel plates have been developed quietly.
You must know that even in 2000, domestic automobile steel plates were basically imported, with very little domestic production, and the quality and technology were not good.
It is conceivable how many years the domestic steel industry lags behind the world in the field of automotive steel plates.
In recent years, some limited resources have been invested in steel used in military products.
For example, China has never given up on research and development of steel used in tanks, warships and other products. Although there is a gap with the world's advanced level, it is not that big a difference.
The situation on the civilian side is different, and the gap is not just a little bit big.
“The Metallurgical Department, the First Machinery Department and the Fifth Machinery Department should all attach great importance to this project. I think inviting experts from each department to come over for a joint review can also be regarded as defining the nature of this matter? ”
Zhu Jiansheng's mind is much brighter now than before.
I took the initiative to report this kind of thing to the Fifth Machinery Department, saying that I and my students proposed a technical solution for high-strength automotive steel plates, and specifically cooperated with the Capital Iron and Steel Institute and Shougang to develop the product, which can be used in the future. If it is used on a large scale in the Hummer project, the impact effect will not be that strong.
But if the news comes from other departments, the situation is different.
For the leaders of the Fifth Machinery Department, the project that Zhu Jiansheng participated in brought them glory.
After all, the development of new steel products is theoretically the responsibility of the Metallurgical Department and has nothing to do with their Fifth Machinery Department. If there is a need for use, the Fifth Machinery Department can submit the request to the Metallurgical Department.
“Okay, leave this matter to us.”
Zuo Guangsheng agreed directly without any hesitation.
After all, Capital Iron and Steel Institute and Capital Institute of Technology have the initiative in this matter.
However, there is no essential competition between Shougang and the two universities. After all, their positioning is different.
In this case, we must try our best to coax the two great professors Zou Yuan and Zhu Jiansheng into good situations.
Maybe there will be unexpected surprises in the future.
“Although high-strength automotive steel plates have been successfully developed, the stamping performance and welding performance of these steels still need to be confirmed by relevant supporting factories.”
“The higher the strength, the better the stamping performance. The performance should have declined to a certain extent. It is also a very critical issue for existing manufacturers to ensure that parts can be produced without re-opening the mold. "
Jiang Hui, who has been silent, A more detailed question was raised.
In the production of auto parts, there are many things that need to be paid attention to.
It is just a simple body stamping part. In fact, it cannot be produced by just any supporting factory.
Especially in 1979, there was a huge gap between the technical level of various supporting factories in China and later generations.
So after changing the materials, whether there are any problems in production is really an important issue.
Especially for the new BJ212, and other models that hope to switch to high-strength automotive steel plates in mass production.
"Judging from the test results of the blanks we are currently doing, although the stamping performance has declined after the strength is increased, the elongation rate has not dropped very much. As long as the parts are not particularly complex, they can be stamped on the original mold. "
"For a small number of stamping parts with special shapes, it may be necessary to modify the mold or adjust the parameters of the stamping equipment."
Zou Yuan stood up and answered Jiang Hui's question. question.
For high-strength steel plates for automobiles, in addition to the key parameters of the tensile strength and yield strength of the steel plate itself, stamping performance and welding performance are also important parameters.
Some steel plates may have very high tensile strength, but their stamping performance is very poor, and there is no way to use them in automotive stamping parts.
After all, the parts on the car, whether it is covering parts such as four doors and two covers, or body skeleton parts, all have some special shapes.
Especially parts such as rear taillights are often deep drawn. Such parts have higher requirements for the stamping performance of steel.
If you are not careful, the parts will crack during the processing, which will definitely not meet the requirements.
As for the welding performance, it is also easy to understand. The body in white is assembled together through the welding process. If the welding performance is not up to standard, various problems such as virtual welding will occur. At that time, the strength of the assembly parts will be reduced. It is very poor, and even the collision performance of the entire vehicle will be greatly reduced.
This is certainly unacceptable.
"We have compiled a list of steel materials in the past two days. Shougang will see if it can produce a batch of materials as soon as possible for us to debug and confirm?"
Chen Qi naturally had to stand up and express his opinions at this time. point of view.
Since Jiang Hui is worried, he must find a way to support Jiang Hui in solving this worry.
Otherwise, it would be a pity if high-strength steel plates cannot be used when the time comes, causing the performance of the new BJ212 to fail to meet the requirements.
“No problem. After we receive your list, we will organize production immediately and strive to complete the delivery of materials within half a month.”
Zuo Guangsheng happily agreed to this request.
Of course, in terms of time, I would not dare to just say that it will be done in a few days.
After all, the production at Shougang is arranged in advance. Once the rhythm is disrupted, it is actually quite troublesome.
There are many types of steel plates required for a vehicle, and it is completely unrealistic to complete them within a few days.
He promised to deliver within half a month, which is already very fast.
For later generations of steel manufacturers, unless the materials you order are in stock, it will take at least three months to respond.
Of course, in some special cases, if someone gives you special support, it can be done in one month, but any shorter time will be very difficult.
“What is being developed now is mainly cold-rolled plain plates, such as some parts on the chassis, which need to be processed with hot-rolled thick plates.”
“There are also some parts that require galvanized sheets. For processing, Shougang also needs to consider how to enrich this product line as soon as possible.”
“Otherwise, other steel mills may see that Shougang’s models are not complete, and they will consider starting to produce other models. ”
Zhu Jiansheng said something from the side.
On the one hand, it is urging Shougang to speed up, and on the other hand, it is also a reminder.
After all, this is entirely possible.
In an era when there was no concept of patents, as long as other steel plants applied to the Ministry of Metallurgy, they would most likely have the opportunity to obtain high-strength automotive steel plate technology.
The premise is that people have a valid reason.
Besides, companies like Anshan Iron and Steel Group are half a level higher than Shougang Group.
This half-level can sometimes play a big role.
Especially in 1979, the administrative level of the company and the level of the relevant departments were basically the same.
“Our technical team will fully communicate with Professor Zou on this matter and strive to develop it all within this year.”
After we have established the foundation, it is difficult to continue to expand other types of steel plates. It's not that big.
Even in the future, it will be much easier for Shougang to develop ultra-high-strength steel plates of 590MPA, 780MPA, or even 980MPA.
Of course, other steel plants will not just watch Shougang take the lead.
After that, everyone exchanged some details about the specific matters, and then went to the production site together for a walk.
In the laboratory of Shougang, we witnessed the test of the tensile strength and yield strength of high-strength automobile steel plates.
After confirming such a complete set of procedures, Chen Qi and Jiang Hui had an idea.
The last important technical issue of the new BJ212 has been basically solved.
The next step is to ask each supporting factory to confirm the stamping and weldability as soon as possible, and then it can be officially loaded and used.
