Rebirth 99 to become a car giant

At this time in 2007, China's comprehensive national strength is definitely not comparable to that in 2023.

At this time, there is still a long way to go before Huaxia becomes the world's second largest economic power.

The self-confidence of the people is actually not very sufficient in many cases.

As for the high-speed rail, it is one of the few projects in China that are relatively affordable.

However, in this project, there are still some key components that need to be imported.

This is very embarrassing.

It is also because of this that after the localization of high-speed rail bearings, it will cause such a big response.

Listening to what Nie Jian said now, the significance of the next project will not be lower than that of high-speed rail bearings.

Cao Yang is naturally very interested.

"Mr. Nie, if you have any orders, just say it!"

"As long as Nanshan Group can do it, I will do my best."

"Nanshan Group has no way to do it now, and we are also concentrating all our resources to make a breakthrough!"

When it's time to speak louder, don't be polite.

The most important thing is that Cao Yang has the confidence to speak louder.

"With Mr. Cao's words, I am completely relieved."

"So far, the most important parts we need to import for high-speed rail are bearings, axles and wheels."

"Among them, the amount of wheels is the largest, and the amount of imports is also the largest."

"This time, what we want to invite Nanshan Group to participate in is the localization project of wheels."

Although Nanshan Group has never made wheels before, Nie Jian is very confident now.

In the past, the high-speed rail bearings were developed by Nanshan Group, because Nanshan Group itself is the leader in the domestic bearing field.

Now the high-speed rail wheels will be developed by Nanshan Group because of Nanshan Group's outstanding performance in the development of high-speed rail bearings.

"High-speed rail wheels?"

Cao Yang naturally has some impressions of this thing, but he still didn't expect that Nie Jian would let himself do this thing.

Relatively speaking, this business is really not what Nanshan Group is good at.

Except for Nanshan Special Steel, other parts that Nanshan Group is making are not directly related to high-speed rail wheels.

"That's right, it's the high-speed rail wheels."

"With the rapid development of Huaxia High-speed Railway, our technology and operation level have attracted widespread attention around the world."

"However, for a long time, the production of Huaxia high-speed rail wheels has been dependent on imports, which has raised doubts about Huaxia high-speed rail technology."

"Claim that 'without imported wheels, China's high-speed rail would not be able to run at all'."

"Although this is hard to hear, it is also true to a certain extent."

"As early as the 1960s and 1970s, foreign countries have begun to develop high-speed rail wheels that can withstand a speed of more than 300 kilometers per hour, while China's high-speed rail started relatively late, and faces a big gap in technology."

"The countries that master the core technology of high-speed rail wheels mainly include Germany, Rome, Japan and France."

"In order to protect the monopoly position of their own technology and maximize their interests, these countries have adopted strict confidentiality measures."

"Implement the 'three nos' policy on cutting-edge high-speed rail wheel technology, that is, not to declare patents, not to publish papers, and not to accept visits."

"This has restricted my country's high-speed rail wheel technology, making it impossible to independently master the core technology and have to rely on imports."

Sensing Cao Yang's confusion, Nie Jian naturally wanted to explain the situation to him.

Later, the research and development of high-speed rail wheels will be carried out in detail, and the two parties must also need further communication.

"The difficulty of high-speed rail wheels lies in high temperature resistance and durability, which requires the purification of steel and the use of advanced technologies such as composite wheels."

"To manufacture high-speed rail wheels that can withstand enormous pressure and high temperature during high-speed driving, special alloy materials need to be selected, precision heat treatment and special rim design are required."

"In the field of wheel manufacturing, high temperature stability, strength and life are the most critical technical problems."

"For a long time, our country has been controlled by others in these aspects and cannot independently produce high-quality high-speed rail wheels, so it relies on imports."

When Nie Jian said this, the expression on his face couldn't help becoming sad.

Like high-speed rail bearings, they also suffered a lot from high-speed rail wheels.

Imported manufacturers of high-speed rail wheels are no better than manufacturers of high-speed rail bearings.

"Mr. Cao, independent research and development and production of high-speed rail wheels can reduce China's dependence on imported wheels, and reduce the impact of external risks and potential sanctions on high-speed rail operations."

"The realization of localized high-speed rail wheels is of great significance to China's economic development and transportation."

"I hope Nanshan Group can help us speed up the localization of high-speed rail wheels."

Nie Jian was really worried that Cao Yang would not accept this project.

After all, it has not been domestically produced for so many years, and it must be because of the high technical threshold.

At that time, a lot of manpower and material resources have been invested, but there has been no result.

Isn't that smashing the Nanshan Group's signboard?

The wheel is the part of the high-speed rail that is in contact with the rail. Unlike the train, the wheel of the high-speed rail not only bears the huge pressure of the high-speed rail carriage during the rapid rotation, but also bears the huge heat generated by friction with the rail. Long-term friction and friction bring high temperature.

If the wheels are faulty, damaged, deformed, etc. during operation, it will be a devastating blow to the entire vehicle, let alone a full vehicle of passengers.

Therefore, this is not just a simple wheel, but also an important guarantee for the safety of passengers' lives and property.

There was a serious high-speed rail accident in Germany, which was caused by a wheel.

In June 1998, a high-speed train suddenly derailed while passing through a village in Saxony. The train carried 287 passengers, resulting in 101 deaths and 105 injuries. The root cause of the accident was The quality of the wheel is not up to standard, and the friction temperature rises, causing the wheel to explode.

Because of this, the most inconspicuous wheel has become a major problem in the development of high-speed rail.

In order to minimize the probability of wheel failure during operation, it means that the purity and stability of the materials used to manufacture high-speed rail wheels must be strictly required, and ordinary manufacturing techniques will not work.

"Mr. Nie, we have a duty to do the localization of high-speed rail wheels."

"However, to be frank, Nanshan Group knows very little about high-speed rail wheels, and has never done research in this area before."

This task, Cao Yang will definitely take it, and he has a way to do it well.

But at this time, it is completely meaningless to say that I can handle it.

It's better to mention the difficulties more, and then give everyone a surprise in the end.

"Qualified high-speed rail wheels have extremely high requirements on load capacity, processing technology, load-bearing design, reduction of wear and thermal expansion and contraction, resistance to metal fatigue, steel properties, casting methods, and impurity content."

"If you want to make a high-speed rail wheel, you need to put the wheel steel in an electric furnace, burn and cut it at a high temperature, and heat it continuously. After a series of operations, a wheel can be manufactured."

"But if you want the wheels to meet the quality requirements, the wheel steel must be kept clean at all times, and the oxygen content must not exceed 0.0002%, otherwise, even if the wheels are made, they will be unqualified."

"For some specific parameters, I will take someone to Yangcheng next week to have a good discussion with your technicians."

"Nanshan Special Steel can produce excellent high-speed rail bearing steel, and I believe it can also produce qualified high-speed rail wheel steel."

Nie Jian now has great confidence in Nanshan Group.

In the past six months, he has been on many business trips to Nanshan Group, and he has a good understanding of the situation of each business department of Nanshan Group.

The more you know, the more you will realize the strength of Nanshan Group.

Nie Jian thought that he had seen a lot in his life.

However, none of the domestic manufacturers like Nanshan Group that has mastered so many core technologies can be found.

The key is that the technology mastered by Nanshan Group is relatively comprehensive, covering all aspects.

So in Nie Jian's view, although high-speed rail wheels are difficult, it depends on Nanshan Group to say which domestic manufacturer is most likely to make a breakthrough in a short period of time.

Nie Jian chatted with Cao Yang about the high-speed rail wheels for about an hour before hanging up the phone reluctantly.

And Cao Yang also took action immediately, calling Xie Lingyun and Dai Hanbiao who had just enjoyed the fruits of victory to him.

Shared some of what Nie Jian said just now with them.

"Mr. Cao, it is a good thing that CSR is willing to ask us to develop high-speed rail wheels."

"However, for this project, we estimate that we need to be prepared for a protracted war."

Xie Lingyun felt a little bitter in his heart, but he didn't dare to show it.

High-speed rail wheels.

As the former deputy chief engineer of Shaogang, how could he not know?

Whether it is CSR or CNR, before that, they did not miss various domestic steel manufacturers to study the localization of high-speed rail wheels.

Because to produce qualified wheels, the most critical thing is to produce qualified steel.

The difficulty of processing, on the contrary, ranks second.

But foreign giants have been covering things for decades, how can you make a breakthrough so easily.

Up to now, apart from the analysis of high-speed rail wheel samples by domestic manufacturers and obtaining part of the data, no one has visited the production site of high-speed rail wheels at the supplier.

"We are professional in making bearings."

"Although the requirements for high-speed rail bearings are different, they are essentially the same."

"But for high-speed rail wheels, we really need to start from scratch and start researching again."

"It may take a long time."

Dai Hanbiao didn't dare to boast easily at this time.

In Nanshan Group, Kua Haikou is responsible.

Don't be embarrassed if you can't produce qualified products by then.

"I understand what you're talking about. Take your time and study it step by step."

"Mr. Nie and the others will come over for a business trip next week, and they will also bring a batch of samples of high-speed rail wheels."

"At the same time, they will also share relevant information accumulated in the past with us, and even arrange for several engineers to stay in Nanshan Group for a long time to assist us in product development."

"Although high-speed rail wheels are relatively difficult, they were able to produce them decades ago, which shows that they are not really difficult to achieve technically."

"It's just that we haven't found the right direction yet."

"Once the threshold is touched, then maybe a breakthrough will be made soon."

Cao Yang naturally felt that Dai Hanbiao and Xie Lingyun lacked confidence.

Although they all expressed that they would go all out for this project, lack of confidence is not a good thing.

So it was Cao Yang's turn to cheer them up at this time.

"That's true. Like some special steels, it's often just the addition ratio of alloy elements. I don't know how to determine it."

"No more, no less."

"It is often not enough to add only one or two alloying elements, and the addition of various alloying elements needs to be considered comprehensively."

"What you may see in the end is a certain material ratio, but in order to get this material ratio, steel manufacturers may spend many years and have done thousands of experiments."

"The manpower, material resources and time cost invested here are very exaggerated."

"So like many special steels, they will not apply for patents, and they will not tell customers the detailed and accurate material ratio."

"Even if there are some hints, it is very abstract."

"For example, what percentage to what percentage of a certain element is contained, it is difficult to have a final result without relying on a large number of experiments on your own."

"Of course, we can also infer some material ratios by combining the effects of the addition of different alloying elements and the various performance requirements of the final material."

"Then verify these inferences through experiments, so as to reduce the relevant investment as much as possible."

Xie Lingyun felt that it was necessary for him to remind Cao Yang that special steel is not so easy to develop.

It is possible to get some technical materials for the previous high-speed rail bearing steel, but it is hard to say whether the steel for high-speed rail wheels can be obtained.

"Mr. Xie, what you said is very reasonable. We will formulate our own test plan based on the information provided by CSR when the time comes."

"Strive to produce special steel that meets the requirements as soon as possible."

Cao Yang didn't discuss this topic with Xie Lingyun for too long.

Anyway, after a period of time, give them a few plans for them to try again, and they will definitely find a result that meets the requirements.

And when Nanshan Group has already started to skip high-speed rail bearings to study high-speed rail wheels, the publicity about high-speed rail bearings on the Internet has just reached its peak.

More and more people realize the significance and difficulty of high-speed rail bearings, and the evaluation of Nanshan Group is naturally higher.

It's just that the higher everyone's evaluation of Nanshan Group and the higher their expectations, the greater the harm some people will suffer.

"I said Xue Wenqiang, how many years have you been with SKF?"

"Didn't you say you were going to change jobs several times before?"

"Why don't you quit now?"

In a restaurant in Shanghai, Xue Wenqiang had dinner with his old classmate Xiao Qin.

But he was not in a good mood at all.

"Hey, I used to think that although SKF's orders in the field of automobiles and machine tools have fallen sharply, but with the support of high-profit products such as high-speed rail bearings, the business will not fail."

"Who knows that even the high-speed rail bearing project will not be able to go on now."

"In order to cope with the rise of your Nanshan Group, our high-speed rail bearings have been reduced by 30% this month."

"And also promised to continue to cut prices in January next year, so that SKF can keep a certain share of high-speed rail bearings."

Although the information Xue Wenqiang said is to a certain extent considered the company's secrets.

But he is also very clear that CSR will definitely share this information with Nanshan Group.

So there is nothing to be afraid of discussing this topic with Xiao Qin now.

Anyway, although Xiao Qin joined Nanshan Group, he was in charge of CNC system and machine tool sales related business at Nanshan Equipment, and had no direct competitive relationship with Xue Wenqiang.

"When you changed jobs, I persuaded you to consider going to work at Nanshan Bearing. You said you would think about it, but in fact you didn't take any action at all."

"It's all right now. After staying for a few more years, I still have to reconsider this issue."

"But at this time, if you want to enter Nanshan Bearing again, I'm afraid it will not be so easy."

"Their sales team has already been set up and is relatively mature."

Xiao Qin is very glad that she switched from Siemens to Nanshan Group.

You know, when she changed jobs, her salary not only did not increase, but dropped a little.

But considering the development prospect of Nanshan Group, she made a decisive decision.

Now she is the sales section chief of Nanshan Group's Shanghai office in charge of machine tools and CNC system-related equipment.

"Nanshan Group is very strong, I have seen this for a long time."

"But I really didn't expect it to be so strong."

"I'm not afraid to tell you that we also have people on the South and North trains."

"We have actually found out about some key time points for the development of high-speed rail bearings by Nanshan Group."

"According to our original speculation, even if Nanshan Group can really handle high-speed rail bearings, it will be five or six years later."

"Who knew that it only took half a year for them to successfully come up with a qualified product."

"It's totally unscientific!"

Xue Wenqiang drank a big gulp of beer very depressed.

Because of the influence of Nanshan Group, all his bonuses this month were wasted.

The point is that the company's prospects are very slim.

Now he even started to expect the company to give him an N+1 and fire him.

He won't feel unwilling to leave with a sum of money like this.

"I'm not boasting."

"In Huaxia, you must not look at Nanshan Group from the perspective of other Huaxia manufacturers, otherwise you will definitely suffer."

"As far as the nut plate from our company is concerned, this part seems not difficult, but there are not many manufacturers in China that can make it."

"There is no manufacturer that can do better and cheaper than Nanshan."

"Not to mention the automatic gearbox at the back, there is no rival in China so far."

"All the vision and attitude towards Huaxia enterprises in the past are doomed to fail when placed on Nanshan Group."

"You are not too old now, so hurry up and find a way to change jobs."

"If you can't go to Nanshan Group, you can go to some other parts manufacturers that have no competitive relationship with Nanshan Group."

"Otherwise, if you continue to stay at SKF, life will definitely become more and more difficult."

Xiao Qin and Xue Wenqiang have known each other for more than ten years.

Naturally, I don't want to see my old classmates live in such a poor way.

To put it bluntly, the rise of Nanshan Group also broke the jobs of many employees of foreign parts giants.
