When the technicians in the factory really understand the smelting materials about special metals they have obtained from Japan, hehe!

When Li Yifan thought of this, he couldn't help but feel excited.

Let’s talk about the most basic special steels, such as galvanized steel plates. This galvanized steel plate is the most basic steel plate material for automobiles.

This most basic material will enter a period of explosive growth in the next few years and will be sought after by many automobile manufacturers in the market.

The cost of this galvanized steel plate is not high and the price is not high. However, due to the large amount of use, it will have a market share of tens of billions every year in the steel market, especially in the domestic steel market.

But even the most basic galvanized steel plate, to be honest, even ten years later, our domestic major factories will not be able to do it well.

For example, Baosteel, which is regarded as the leader by the country, has specially introduced this technology from South Korea's Posco Iron Manufacturing, but even the technology introduced is still not good at production.

The galvanized plates we produce often have the disadvantages of uneven galvanized plates and high waste rate, which leads to excessive production costs. In this way, our products are not competitive in the market compared with those of other and foreign galvanized plates.

This can be seen from the local automobile manufacturer in Puhai that when people produce higher-end cars, they would rather import galvanized steel plates from Europe in large quantities than use galvanized plates produced by Puhai. This is the most advantageous proof.

A few years later, a small and medium-sized automobile manufacturing enterprise in the south, in order to save costs, entered a batch of galvanized plates produced by a domestic steel mill. As a result, the automobiles produced were used for only three years and the chassis steel plates were rusted and rotten, and even attended the 315 complaint party of the imperial court.

That time, a domestic automobile manufacturer and a domestic steel company were well-known.

I have been in joint ventures with a state-owned automobile manufacturer for decades, but even a simple galvanized plate could not be done with the engine. At that time, domestic automobile manufacturers were scolded by consumers for a long time on this issue.

Of course, this cannot be blamed on other automobile manufacturers. The domestic steel mills also have great responsibilities.

Now, the simplest galvanized steel plate technology is just a piece of cake for Li Yifan’s special metal smelting company.

After the factory technicians have completed the large-scale smelting and quantitative production technology of special metal profiles for construction, they will enter this field.

With the help of Li Yifan's information, their work can be said to be twice the result with half the effort.

And this is just the mid- and low-end products of Li Yifan's special metal smelting company. He himself is more interested in mid- and high-end technologies.

And this mid-to-high-end technology is quite remarkable, such as the technology of producing diamonds under high temperature and high pressure, to put it bluntly, it is the technology of artificial diamonds.

If this technology is developed, it will definitely make up for a big gap in China. This kind of artificial diamond is of great use, especially in the field of machine tool production and processing.

There are many machine tools that use diamond tools or tools coated with a layer of diamond powder film. We can't produce such tools now.

Another one is boron nitride technology. When it comes to boron nitride, many people don’t know so, but this is also a powder material, and it also needs to be plated on metal tools through coating technology.

Tools plated with this boron nitride film are basically used on machine tool processing tools. Moreover, this boron nitride film has a low cost diamond film, so it is more popular.

It was the mainstream product in the world's processing machine tool tool industry a few years later.

Let’s not talk about machine tools for now. Ten years later, the scale of the tool used in domestic processing machine tools alone can reach 70 billion every year, and this market has basically been monopolized by Japan, the United States and Germany.

If we can master this technology, it means that this market will definitely have a place.

These are all small colors. What Li Yifan is most concerned about is the application of these coating products in the automotive industry.

One of the three giants in Japan's automobile manufacturing industry, Nissan, has always been a very diverse and distinctive automobile manufacturing company.

While other automobile manufacturers are working on the research and development of six-speed, seven-speed, or even eight-speed transmissions in the field of transmissions, this company has been working on the research and development of their CVT continuously variable transmissions.

This kind of continuously variable transmission also has a considerable reputation in the field of automotive transmissions.

This kind of transmission has been born for many years, but due to some inherent defects, this kind of transmission has never become the mainstream of automotive automatic transmissions.

For example, a chain is needed between such transmissions as a transmission link. In the early stages of the car, belt slips due to low speed and high torque output.

In other words, it is easy to lose files in the early stages.

Moreover, this kind of transmission usually fails due to bond metal fatigue after use for 40,000 kilometers. Once it fails, it will face a situation of overhaul. Therefore, this transmission has always been a transmission criticized by many consumers.

However, this kind of transmission also has its own benefits. For example, because it does not require a hydraulic matrix to shift gears like a hydraulic transmission, there is no gear shifting impact and the driving comfort is very high.

And because of its simple structure, it has outstanding performance in fuel-saving performance, etc.

It was precisely because of the two points of the CVT transmission that Nissan took this transmission as its main research and development direction.

After years of research, it is the breakthroughs in the above coating technology that have also made corresponding breakthroughs in the research and development of such transmissions.

Especially the diamond production and coating technology have made Nissan's transmission and engines very good technological progress.

One of their engines is based on the technology of placing a layer of diamond film on the piston and cylinder head, which greatly reduces friction resistance, improves fuel economy, and greatly reduces noise.

With this coating technology alone, this engine has been rated as one of the top ten engines in the world for several consecutive years without any new technologies such as turbines and direct injection. The reason is simple, it is fuel-saving, low noise and comfortable.

Their transmission also uses this diamond coating technology. After using this coating technology, their transmission metal bonds have stronger strength, longer life, and significantly improved economicality, and slippage has been effectively curbed.

Their continuously variable transmission has become a unique landscape among many automatic transmissions in later generations with such a unique technology.

While other automobile companies were still worried about increasing the gears of the transmission, Nissan had already relied on their unique CVT transmission and became a proud man.

Fuel-saving, comfortable and reliable have become their selling points. The first two are true. As for reliability, although it is worth discussing, how can ordinary consumers understand so much?

Li Yifan is also very optimistic about these two technologies, which are used in the fields of automotive engines and transmissions, so he brought these two technologies back from Japan.

As long as these two technologies are made breakthroughs, in the future, these two technologies will have more scope of application in China.

So these are promising technologies. Apart from these two technologies, he still has a lot of technologies waiting for the technicians of those factories to develop.

When Li Yifan thought of this, he decided to go to the special metal smelting company tomorrow to take a look.

Another thing that Li Yifan is very concerned about is that the two domestic 3D printing masters he contacted before, Yao Chongshan and Hu Bin, should have been in place.

When he met Hu Bin in Central China last time, Yao Chongshan and Hu Bin hit it off at first sight and were not even willing to go back to Bincheng. They also wanted to stay by Hu Bin's side to ask him about some knowledge about 3D printing technology.

When Li Yifan left, they chose to stay in central China and settled the annoying Japanese first. It was their statement, but in fact, it was because Li Yifan was in trouble and wanted them to trick the Japanese.

Later he returned to the capital, and he didn't know how the two of them implemented it.

However, some time ago, Hu Bin called himself and said that he had completed the handover in Central China. He also completed the procedures for suspending salary from Huazhong University of Science and Technology and was about to go to Bincheng.

When Li Yifan received his call, he was very happy and called his home specifically, asking his father not to neglect these two and to settle their food and accommodation well.

However, it is getting late now, and it is not suitable to continue discussing this topic with my father and others, especially after Li Yifan saw that his father and mother on the opposite side could not hide his tiredness.

Although the old couple's current physical fitness is much better than in their previous life, they are old after all, and it seems that there is no trouble to worry about this day, but in fact they are quite a lot of things to worry about.
