reborn industrial empire

"Are you telling the truth?"

After listening to Jin Xiaoqiang's introduction, Minister Liu was so surprised that his jaw almost dropped to the floor. Liu Yonghao on the other side was even more excited and slapped his thigh. If what Jin Xiaoqiang said was true,

If so, it means that the level of industrial processing in our country is really on the next level!

The effect is definitely the same as before without any adulteration!

As a train engineer and a semi-expert specializing in various industrial knowledge, Minister Liu is quite discerning. He has long heard about the bainite austempering process for bearing steel mentioned by Jin Xiaoqiang.

Said it before.

In fact, the Germans and French have been developing this technology for decades. For the Western world, this technology is nothing new at all.

But for our country, this thing is a good thing. Our country has also organized many xxx project teams, or xxx R&D plans, etc., and administratively stipulates that these subjects can be publicized within a certain number of years.

But when the years passed, a large project team found that, except for a few successful projects, others achieved nothing. Of course, this cannot be blamed on those scientists for not working hard, but it is really because some projects are not

You can study it by slamming the table, throwing down the bench, shouting slogans, and expressing your determination.

You must abide by considerable natural laws, have a considerable accumulation of basic knowledge, and go through thousands of experiments before you can study it, rather than just slap on the forehead.

Such bainite austempering technology was developed by Jin Xiaoqiang and others after thousands of experiments, tens of millions of dollars spent, and Jin Xiaoqiang's full firepower.

In fact, as early as the last century, when people began to play with high-speed rail, they began to study this kind of special steel. The concept of this special steel originated in Japan, because Japan was the first country to start playing with high-speed rail. As early as people started

When designing and manufacturing high-speed trains, they began to research various bearings and wheels suitable for such high-speed trains.

And they were the first country to discover that low-carbon steel is actually more suitable for making such bearings and body steel wheels. Later, Europeans also began to play with high-speed rail, and France and Germany began to join forces to develop Eurostar. However, in terms of the materials of wheels and bearings,

It has also been hindered, but after all, it is the birthplace of modern high-tech and metal smelting technology, and its technical foundation is really rich. After many years of research and development, it was the French company Valdunes that took the lead in developing a new steel type.

.

This special steel has a lower carbon content than the steel for bearings and wheels previously used on high-speed rail, and its strength limit is around 886 MPa. It is similar in strength to the r8t type special steel previously used on bearings and wheels on high-speed rail.

, but its impact resistance is more than one-third stronger than the original r8t model of special steel. In this way, the life of the bearings and wheels made of this special steel will be longer than the original wheels.

About three times.

Later, the Germans continued to conduct in-depth research on this steel material. They found that this kind of special steel mainly composed of bainite was better than the original ferrite plus pearlite in terms of wear resistance and smoothness.

The special steel was much stronger, so they continued to develop it and developed more advanced special steel with superior performance. They also optimized the smelting process and technology of this special steel, which greatly reduced the cost of smelting this special steel.

cost.

Later, a large number of bearings and wheels made of this special steel appeared on high-speed trains in Germany and France. The Chinese Railway Ministry had previously negotiated with the Germans and the French, and the main focus of the negotiations was

.Can the Germans and French transfer the smelting technology of this special steel to China?

But it is a pity that the last request was rejected with great shame. Unless the person is a fool, who would be willing to transfer such technology to the people of China? After all, our China is in the eyes of others. But a person who doesn’t

It's a big deal. No matter whether we give them technology today or not, these Chinese people will still come to them in the future and demand to buy their bearings.

In the original history, Germany's

It was precisely by relying on this technology that Schaeffler finally monopolized the supply of bearings for China's high-speed railway.

But in this life, if nothing unexpected happens, they won't even think about it.

In fact, the reason why Jin Xiaoqiang developed this kind of special steel is mainly because of the super sports cars they will launch this year. Why was it said before that a car can reflect a country's most important comprehensive industrial capabilities?

In fact, the simplest reason is the materials you use on this car. For example, the Fire Horse and the Son of Darkness that they released a few years ago. Because these two supercars are equipped with extremely powerful engines, they can use as much horsepower as they want.

It can reach more than 500, or even 700 or 800 horsepower. If modified, the horsepower will exceed 1,000 in a matter of minutes.

But while your engine can produce such a large power, don't ignore that the bearing on the output shaft of the engine will rotate crazily with the movement of the engine. The output shaft of a general engine rotates crazily every time.

It is already very impressive to be able to make five or six thousand rpm per minute, but the engines of these supercars have to turn to seven or eight thousand rpm at the craziest time in a minute, and even close to nine thousand rpm at the highest point.

After modification, it may even exceed tens of thousands of revolutions.

How can ordinary bearings bear such a speed?

In the end, in order to find a more suitable bearing material, Jin Xiaoqiang had no choice but to focus on this type of train bearing, which is widely used in European high-speed railways.

Don't look at it. According to the speed of high-speed rail, the rotation speed per minute that this kind of bearing can achieve is not very high, only 2,400 to 3,000 rpm. However, it is a high-speed rail train that has to withstand hundreds of tons or even thousands of tons.

of output power.

So if a bearing made of this special steel is used to withstand the power that a car weighing only one or two tons can output, it is more than enough.

After developing this bearing made of special steel, Jin Xiaoqiang's supercar plan has the most solid foundation.

But to be honest, he never considered at that time that he would use this special steel for China's high-speed rail, because he had never considered this before.

At that time, in order to find a suitable supercar bearing, Jin Xiaoqiang took great pains, went through the information in his head, and chose this special steel.

At that time, he also thought that if this special steel failed, he would have to choose another special steel from Japan to copy.

This special steel is the high-precision sae4320 steel that the Japanese later carefully crafted. This special steel was obtained from Japan by Shinyuki Naruto through some means.

This is also a new type of special steel that the Japanese government launched after seeing that Europe had developed a new type of special steel that broke their original monopoly in the high-speed rail bearing market.

This special steel uses the latest super technology, and this technology was originally used to make special steel for aircraft engines.

Later, Japan's Sanyo Heavy Industries used this technology to smelt bearings and achieved a major breakthrough. Later, the special steel-supported bearings and body steel wheels produced using this advanced process were all used on the Shinkansen.

On board the 700 series high-speed train.

After Jin Xiaoqiang obtained the formula and smelting technology of this special steel from Naruto Shinyuki, he was even more ecstatic. You must know that this special steel can not only meet their needs for automobile bearings, but also satisfy their needs.

The bearings of the machine tools produced are also applicable to the bearings used for aircraft in the future. This is a very impressive technology and process!

Although Huayang Dynamics currently does not plan to promote this technology on a large scale, because the materials produced by their current technology are sufficient. After all, after investing so much, they have to recover a certain amount of profits from the market.

But Jin Xiaoqiang did not give up. He wanted this special steel the most. After obtaining the material formula and smelting process of this special steel, he specially organized manpower to test and refine this special steel.

And in June this year, Huayang Power's special metal smelting center finally completed the production of this special steel, and has been able to truly master the core technology and processes of this special steel. Once it is

If there is demand, we can achieve rapid quantitative production.

After that, Jin Xiaoqiang asked the engineers in his special steel R&D center to continue to develop his own special steel based on this information, so that in the future, we Chinese people can have a place in the world's special steel field.

These technologies will also be reserved as Huayang Power's technology reserves. Although they do not need to be put on the market yet, they must be achieved so that they can be mass-produced as soon as the market requires them.

Now that Minister Liu has a need, and judging from his intentions, he still plans to buy foreign goods, Jin Xiaoqiang has to come up with these technologies in advance.

"Xiao Jin, what you said before is true?"

It was the first time that Minister Liu greeted Jin Xiaoqiang so intimately. At this time, he also seemed a little excited. His forehead, which was already shiny, showed slight sweat stains. He seemed a little excited.

"Then there's still a lie?"

Jin Xiaoqiang replied a little arrogantly, "Well, I finally shocked you, the old fox, right?" Jin Xiaoqiang felt a little proud.
