Wait until the technicians in those factories really eat the smelting materials about special metals that they got from Japan, hehe!

As soon as he thought of this, Li Yifan couldn't help but feel his blood boiling.

Let's talk about the most basic special steels, such as galvanized steel, which is the most basic steel sheet material for automobiles.

This most basic material will enter an explosive period in the domestic automobile industry 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, but because of the large amount, there will be tens of billions of market shares in the steel market, especially in the domestic steel market.

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

For example, Baosteel, which is regarded as the leading brother by the state, has specially introduced this technology from South Korea's POSCO, but even if it is the imported technology, it is still not competitive in terms of production.

The galvanized sheet we produce often has the shortcomings of uneven galvanization and high scrap rate, which leads to high production costs, and in this way, our products have no market competitiveness in the market compared with foreign galvanized sheets.

This can be seen from the local Puhai and German joint venture automobile manufacturing enterprises, when people produce high-end cars, they would rather import galvanized steel sheets from Europe in large quantities than use your local Puhai galvanized sheets, which is the most favorable proof.

And 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 sheets produced by a domestic steel mill, and the resulting cars were used for only three years, and the chassis steel plates were rusted and rotten, and even went to the 315 complaint party of the imperial court.

That time made a domestic automobile manufacturing enterprise and a domestic steel company very famous.

It has been a joint venture with other state-owned automobile manufacturing enterprises for decades, but it turns out that even a simple galvanized sheet can't be used for the engine. At that time, it was just on this issue. Domestic automobile manufacturers have been scolded by consumers for a long time.

Of course, this can't be blamed on other automobile manufacturers, and those domestic steel mills also have a lot of responsibility.

And now this simplest galvanized steel plate technology is for Li Yifan's special metal smelting company. It's just a piece of cake.

Wait until the factory technicians have it done. Large-scale smelting of special metal profiles for those constructions. Once the production technology is quantified, 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 only Li Yifan's special metal smelting enterprise. For low-end products, he himself is more interested in mid-to-high-end technology.

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 man-made diamonds.

If this technology is developed, it will definitely be able to make up for a big gap in China, and the usefulness of this synthetic diamond can be great, 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, and we can't produce such tools at all.

There is another one is boron nitride technology, speaking of boron nitride, many people don't know, but this is also a powder material, which is also plated on metal tools through coating technology.

The tool coated with this boron nitride film is basically used in the machine tool processing tool, and this boron nitride film has a low cost of diamond film, so it is more popular.

A few years later, it is the mainstream product of the world's machining machine tool industry.

Machine tools aside, ten years later, in the domestic processing machine tool market alone, the size of the market can reach 70 billion per year, and this market has basically been monopolized by Japan, the United States, and Germany.

If we can master this technology, then it means that there will definitely be a place for us in this market.

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

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

While other car manufacturers are working on the 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 great reputation in the field of automobile transmission.

This kind of transmission has been born for many years, but due to some congenital defects, this kind of transmission has not been able to become the mainstream of automobile automatic transmission.

For example, a chain is required between the transmissions, and in the early stages of the car, the belt often slips due to the low speed and high torque output.

In other words, in the initial stage, it is easy to lose gears.

And this kind of transmission, generally after 40,000 kilometers of use, will be due to the fatigue of the link metal, and failure, once it fails, it will face the situation of overhaul, so this kind of transmission has been criticized by many consumers as a transmission.

But this transmission also has its own advantages, such as because it does not require a hydraulic matrix to shift gears like a hydraulic transmission, so there is no shift shock, and the driving comfort is high.

And because of the simple structure, it is outstanding in terms of fuel-saving performance.

And Nissan is following these two points of this CVT transmission, and it is taking this transmission as its main research and development direction.

After years of research, it is the breakthrough of the above-mentioned coating technology that has allowed them to make corresponding breakthroughs in the research and development of this kind of transmission.

In particular, this diamond production and coating technology has enabled Nissan to make very good technological progress in both transmissions and engines.

One of their engines relies on the technology of coating the piston and cylinder head with a layer of diamond film, which greatly reduces frictional resistance, improves fuel economy, and greatly reduces noise.

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

Their transmissions also use this diamond coating technology, and after using this coating technology, their transmission metal ties have stronger strength, longer life, and the economy has also been significantly improved, and the slippage phenomenon has been effectively curbed.

And their continuously variable transmission, relying on such a unique technology, has become a unique landscape in many automatic transmissions in later generations.

When other auto companies are still desperately worrying about increasing the gears of the transmission, Nissan has already relied on their unique CVT transmission, and is proud of the rivers and lakes.

Fuel-efficient, comfortable, and reliable, have become their selling points, the first two are true, as for reliability, although it is debatable, but how can ordinary consumers understand so much?

And Li Yifan is also very optimistic about the application of these two technologies in the field of automobile engines and transmissions, so he brought these two technologies back from Japan.

As long as there is a breakthrough in these two technologies, then in the future, in China, these two technologies can be applied to a wider range.

So these are all promising technologies, and apart from these two technologies, he has a lot of technologies in his hands, waiting for the technicians of those factories to develop.

As soon as he thought of this, Li Yifan decided to go to the special metal smelting company tomorrow to have a look.

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

The last time he met Hu Bin in Central China, Yao Chongshan and Hu Bin hit it off at first sight, and they didn't even want to go back to Bincheng, but they wanted to stay by Hu Bin's side and ask him for some knowledge about 3D printing technology.

And when Li Yifan left, the two of them chose to stay in Central China, and first ended up with those hated Japanese, it was the two of them who said, in fact, it was because Li Yifan was in bad water, and he wanted the two of them to pit those Japanese.

Later, when he returned to the capital, he didn't know exactly how the two of them carried it out.

However, some time ago, Hu Bin called himself, saying that he had completed the handover in Central China, and he himself had gone through the procedures for leave without pay from Huazhong University of Science and Technology, and was about to go to Bincheng.

When he received his call at that time, Li Yifan was still very happy, and he made a special call to the family, asking his father not to neglect these two, and to settle their food and lodging well.

But now that it's getting late, it's not suitable to continue discussing this topic with his father, especially after Li Yifan has seen that his father and mother on the other side can't hide their tiredness.

Although the physical fitness of the old couple is much better than in the previous life, after all, they are older, and at the end of this day, it seems that there is nothing to worry about, but in fact, there are a lot of things to worry about.

Li Yifan hurriedly greeted his parents, saying that he was a little tired and wanted to rest, let them rest early, Li Liqiang and his wife were also a little tired, so they readily agreed, Li Yifan said goodbye and left the office and went back to his room...... (To be continued......)
