Chapter 367 Sister and Brother-in-law
Hou Guoming and Chen Chenxing both have part-time jobs at Nanshan Technology.
As talents with a certain understanding of various parts on a car, the two of them had very different reactions after hearing Jiang Hui's hot stamping plan.
"Director, I think if this hot stamping technology is successfully used on Land Rover off-road vehicles, it will be very helpful for our products to spread around the world."
“In the field of off-road vehicles, consumers attach much higher importance to the strength of the vehicle than to ordinary models.”
"Especially when some people really want to drive these cars to places with poor road conditions. If the body strength is not good enough, users will have a lot of worries."
"When a car accident occurs, the impact is even more obvious."
"As long as we do a good job in publicity, we can completely use this point to build a reputation for good performance of off-road vehicles."
"Combined with the stunning appearance of the Land Rover off-road vehicle, it will be much easier to sell it well."
As the person in charge of the sales field, Chen Chenxing is very aware of the importance of an impactful selling point to a product.
Hot stamping technology can increase the tensile strength of steel plates from more than 200 MPa to more than 1,000 MPa, and even reach an exaggerated 2,000 MPa.
This is completely impossible with the cold stamping process.
Many parts companies in Japan in later generations can perform cold stamping forming processes of 980MP and 1180MPA steel plates, which can compete with hot stamping to a certain extent.
But now 440MPA is considered a high-strength steel plate, which is used in only a few key parts of most cars. The high-strength automotive steel plates of 980MPA and 1180MPA are not even mass-produced.
Against such a background, Land Rover off-road vehicle developed a 1500MPA hot stamping process to weld parts into key parts of the body. The impact was absolutely huge.
Chen Chenxing has already started thinking about how to use this hot spot for publicity.
However, as the technical person in charge, Hou Guoming had different considerations from Chen Chenxing.
"So far, only Saab has tried to use hot stamping parts on one model. Auto giants such as Toyota, General Motors, Ford and BMW have not yet started to use hot stamping technology."
"I don't think it's because the engineers responsible for body design in these car companies have poor vision, but because the hot stamping technology is too immature."
"We want to use it on Land Rover off-road vehicles, which is very likely to cause a delay in the mass production of Land Rover off-road vehicles, or even make mass production impossible."
"This result is difficult to accept, so until there is no concrete prospect for the mass production application of hot stamping technology, I do not strongly support its direct use on Land Rover off-road vehicles."
Hou Guoming had no doubts about Jiang Hui's vision, and he also knew that Jiang Hui's technical level was very high.
However, the technology in this area has never been studied in China, and both materials and equipment are in short supply.
There are even very few companies in the world that are doing research in this field. It is extremely difficult to make big breakthroughs in a short period of time.
If it really delays the mass production of a promising model like the Land Rover off-road vehicle, Hou Guoming feels that the gain outweighs the loss.
"Those automotive giants do not use hot stamping technology extensively. I think the most critical reason is not because the hot stamping technology is not mature, but because the hot stamping parts produced abroad are too expensive."
"No one in the entire automotive industry is using this technology on a large scale, and consumers' requirements for vehicle strength are not yet very high. It is completely understandable that the automotive giants do not want to spend more money for their own benefit."< br>
"Otherwise, the heating furnace, press, or laser cutting machine that processes hot stamping parts is actually not very different from other similar equipment used in the industrial industry. It only needs a slight modification. Available.”
"Just like a heating furnace, heating steel plates to a high temperature of about 900 degrees. Are there any technical difficulties? Absolutely not!"
"Another example is the press. Compared with traditional cold stamping, the biggest feature of hot stamping technology is pressure maintaining, which results in low production efficiency. We can just use a hydraulic press directly."
"There is almost no need to make too many changes to this backward-looking hydraulic press. I think it will be enough."
"I will also contact Ji'er Machine Tool Factory directly later to see if they have an 800-ton or 1,000-ton hydraulic press. I can just buy one and bring it back."
Regarding the key equipment of the hot stamping molding process, Jiang Hui directly expressed his views.
There is a threshold for this kind of equipment, but it is definitely not as high as everyone thinks.
Especially now, the requirements for hot stamped parts are not as high as those of later generations. Even if there are some quality defects, it is actually acceptable.
For example, later hot stamping molded parts require that the strength of any part can reach 1500MPA.
This requires very high requirements for the layout and design of the mold water channel. If you are not careful, some places will reach 1500MPA, some places will only have 1200MPA due to insufficient quenching, and even the tensile strength will only be 800MPA.
In the absence of competitors, such defective parts from later generations are no problem at all now.
If you have the ability to say that I can't do it, then you have to wait until other manufacturers start using better technology than Land Rover off-road vehicles.
Similarly, the heating furnace has very high requirements for temperature stability control. If the fluctuation is relatively large within the specified range, it is likely that the metallographic structure inside the steel plate will not be fully austenitized, which will ultimately affect the quality of the steel plate after quenching. strength.
This problem is the same as the mold water channel design problem just now. It is not a fatal problem now.
On the contrary, Jiang Hui feels that domestic equipment manufacturers may not be able to produce machine tools for processing mold water channels, and they may need to be imported from abroad.
Although Nanshan Equipment will have to build this kind of machine tool itself sooner or later, it may not be able to catch up in a short time, so it can be considered to import one first.
Anyway, given China's friendly relationship with the United States at this time, even if the imported machine tools were products that had been restricted from being exported to China in the past, it would still be possible to succeed.
After all, importers and users are both port-city enterprises, not Chinese state-owned enterprises.
As for laser cutting equipment, domestic technology is not particularly backward. It is just that the speed and precision of laser cutting are not particularly high.
But it’s harmless and does not affect the competitiveness of Land Rover’s off-road vehicles.
When these issues are not a problem, cost is even less of an issue.
The gap between workers' wages in China and Europe and the United States is really huge.
Therefore, even if the processing time of hot stamped parts is several times that of traditional cold stamped parts, the final increase in processing costs will be relatively limited.
As for the amortization expenses of various other equipment, as long as imported equipment is not used, the impact is also very limited.
A domestic heating furnace can be built for less than 100,000 yuan.
Similarly, the price of domestic laser equipment is almost at this level.
Although 100,000 yuan in this era is actually not cheap, when amortized to each car, the cost increases by less than one yuan, which is completely trivial.
Jiang Hui has a clear idea in his mind, so it is imperative to vigorously develop hot stamping technology and regard it as an important weapon for Land Rover cars to go global.
Feeling Jiang Hui's strong determination, Hou Guoming could only bite the bullet and move forward.
Fortunately, from the perspective of automotive parts design, the design of hot stamped parts is almost the same as the design of cold stamped parts. Even because the molding performance of hot stamped parts is better, the design of the parts can be more complex without fear.
This allows the fitting parts to be designed simpler, thereby reducing the difficulty of producing the fitting parts, which is also an advantage of using hot stamping formed parts.
……
"Lingling, my sister and brother-in-law have been working in Shanghai for many years, but their levels have not improved much."
"Our family doesn't have much influence in Shanghai. For better development, what do you think about inviting them to work in Shenzhen?"
When he got home in the evening, Jiang Hui set his sights on Zhu Ling's sister and brother-in-law.
One of them works in a hospital and the other works in Baosteel.
If they can be invited over, then the preparation work of the group-affiliated hospital can be left to my sister, and the research and development of hot stamping steel plates can be left to my brother-in-law.
At that time, it would be even better if we could use our brother-in-law's relationship to convince Baosteel to cooperate with BMW in the research and development and production of hot stamped steel plates.
After all, as a steel plant that was a key development project in the country in the past few years, Baosteel's equipment and technology are among the best in the country.
By cooperating with them, Jiang Hui feels that hot stamping steel plates will be developed faster.

Of course, Baosteel is definitely not the only choice. Shougang, Anshan Iron and Steel, and even Shaogang Iron and Steel here in Lingnan Province can actually be considered.
"Would you mind letting them come to work in the group?"
Zhu Ling looked at Jiang Hui expectantly.
In fact, she had already had this idea.
Unlike many people in this era who have five or six brothers and sisters, Zhu Ling only has one sister.
But the two sisters rarely see each other once a year, and this situation is definitely not what she wants to see.
"What's there to worry about? Originally, I was worried that they would get used to their current job and not want to come out."
"And when you work within the system, your social status is definitely different from when you work in a private enterprise."
"But now our group is short of technical experts who are proficient in materials. I think it would be very meaningful for us if my brother-in-law is willing to come."
Jiang Hui has no plans to build a steel plant of his own in the short term, but in the long run, a special steel processing plant belonging to the BMW Group is still necessary.
Otherwise, with domestic special steel technology, when the technology of many parts wants to be further improved, they will encounter material bottlenecks.
Even if it can be imported from abroad, the cost will be unbearable.
What's more, even if you want to import some key special steel, they won't sell it.
"Although my sister and brother-in-law are considered leaders in their unit, their room for advancement is limited."
"Our BMW Group is no longer what it used to be, and there is no need to worry about their treatment in all aspects after they come here."
"There will definitely be a bigger stage for them to display their abilities in the future."
"So as long as you sincerely invite them, they will definitely be willing to come."
"I'll call my sister now."
After Zhu Ling finished speaking, she immediately started to take action.
……
"Wu Ming, Linlin wants me to help build the BMW Group Affiliated Hospital. At that time, this hospital will import a batch of equipment from abroad, cooperate with Shenzhen to build it, and develop into one of the top hospitals in Shenzhen."
"She also said that Jiang Hui hopes that you will go to the BMW Group to help with steel research. There is a deputy director position at the R&D center that will be reserved for you first."
"What do you think?"
Although Zhu Fang was already moved, she still did not directly agree to her sister's suggestion just on the phone.
For such a big matter, I definitely need to discuss it with my husband.
“The main business of the BMW Group now is the production of BMW Light, and the steel plates are purchased from the Capital Steel Plant.”
"There should be no information about the country letting foreign investment or private enterprises enter the steel field, right?"
Wu Ming didn't particularly understand Jiang Hui's arrangement. After all, it was just the two sisters Zhu Fang who were talking on the phone.
"Jiang Hui will call you tomorrow to tell you the specific situation, but since he said he needs your help, he shouldn't be polite."
"Although you are the head of the technical section in your unit, it is probably difficult to get promoted."
"It will be different when we go to the BMW Group. Jiang Hui and his wife will definitely not treat us badly."
Thinking about the small house she lives in now, and thinking about her sister's house she saw when she went to Shenzhen on a business trip last year, Zhu Fang no longer wants to stay in Shanghai.
As the largest city in China, the housing situation in Shanghai is the most tense.
Even though the housing conditions of Zhu Fang and his wife were quite good, considering that there were five children living together, the situation was not good at all.
"I'll call Dad tomorrow morning to discuss it and see what he thinks."
Wu Ming's own family was just an ordinary working class person. Although the social status of the working class in this era was very high, it could not provide any special help to his personal development.
My father-in-law is now the principal of a school. If he goes further in the future, his influence will be completely different.
Wu Ming had been staying with Baosteel honestly before, just wanting to wait for Zhu Jiansheng to be promoted to see if his future would turn around.
Now that Jiang Hui suddenly said that he wanted to invite him to Shen City, he was a little confused.
"You might as well ask Dad. The current situation is very different from previous years. Dad must know more information than we do."
"Whether it is better to stay in Shanghai or go to Shenzhen, he should give us some opinions."
Zhu Fang did not continue to persuade Wu Ming and gave him some time to think about it. The effect might be better by then.
