Even the most amateur Lin Zhuanxi knows that the current accuracy of machine tools is indeed inferior to that of developed countries.

The accuracy of machine tools is also a huge problem affecting the current manufacturing industry in China.

In order to make a machine tool with extremely high precision, it is necessary to make a truly strong steel material with a very high standard of hardness and toughness.

This is the realm of materials science.

In this regard, it is indeed much inferior to developed countries such as Europe and the United States.

And now, +7 valence iron has been discovered!

The discovery of +7 valence iron can make steel materials even tougher and stronger.

Make even more terrifying machines!

"The +7 valence iron in these ores shouldn't be a lot in total, right?"

"Even if you want to make a machine tool, I'm afraid you can only make one or two. ”

"It doesn't mean much. ”

Lin Zhuanxi opened his mouth and said.

"Not really!"

Ji Chen shook his head slightly.

"The discovery of +7 valence fills the gap in iron research around the world. ”

"This is a breakthrough step!"

"Scientists get these +7 valence iron, and they can do reverse research. ”

"In this way, the key technology will be obtained, and ordinary iron will also be turned into +7 valence iron. ”

Ji Chen said.

The greatest significance of the discovery of +7 valence iron is a qualitative change from scratch!

As long as the first stable +7 valence iron ion is available, chemists can then study and make second, third, and even fourth and fifth +7 valence iron.

As a result, a myriad of powerful new ferroalloys have been created.

Manufactured countless world-leading precision machine tools!

"I see!"

Lin Zhuanxi nodded immediately.

The discovery of +7 valence iron, its practical significance, is terrifying.

One step ahead in steel materials and manufacturing the world's top machine tools, we will be able to lead the world in various industries.

Let the whole world be out of reach!

One of the most common applications, and the most profitable ones, is the automotive industry.

The automobile industry is booming all over the world, and the automobile industry in China is also developing rapidly.

However, there are still some places where Huaxia's automobile industry lags behind Europe and the United States.

Engine technology is ok.

The main one, one is gearbox technology.

One is chassis tuning technology.

Transmission technology, mainly technical patents, are in the hands of European and American companies.

If Huaxia wants to study, it also needs to avoid their patents.

People have explored the fastest and best shortcut, but because of patent barriers, you can't go!

If you want to go, you have to take a detour from the side.

In this case, how to catch up?

Chassis tuning involves some aspects of machine tool precision.

Huaxia is also at a great disadvantage.

Now, once you have the most powerful machine in the world, and you can make a stronger and tougher steel alloy out of +7 valence.

These problems can be solved!

In the automobile industry, there have long been a lot of black technologies.

Because it is limited by the strength of the material, it cannot be applied!

For example, the engine, which is currently the best engine in Fuso, has a thermal efficiency of 40%.

In fact, Huaxia has developed some engines in extreme circumstances, and the thermal efficiency can reach 50% or even close to 60%!

The problem is that it is limited by the material of the cylinder block and so on, and it is not durable.

The engine rotates for a few minutes and is directly scrapped, and no matter how high the efficiency is, it cannot be applied.

Now, if we can make an extremely tough steel alloy into an engine block.

There is no problem in bringing the black technology into play and creating an engine with a thermal efficiency of 50 or 60 percent!

And the transmission!

Huaxia also has new transmission technology.

But it's basically too aggressive and not durable!

Replace it with strong and tough steel, and everything will be solved.

The same is true for chassis technology, at that time, Huaxia will make more powerful cars with lower costs, which can completely defeat all foreign car companies!

What a huge profit it brings!

It can be said that after getting the +7 valence iron, Suya Group can immediately start a Suya Automobile Group, and it will not take a few years to occupy the global market without the slightest problem!

The profits brought by it are more than hundreds of millions!

The global automobile, the annual profit is more than 50 billion US dollars.

When the time comes, it will inevitably be monopolized by the Suya Group.

And Jingcheng University of Technology, because of Professor Huang's decision to cooperate, may be able to net income of 10 billion US dollars a year.

How terrifying!

When the time comes, it will be very easy to reward Professor Huang with one or two hundred million dollars.

In the future, Professor Huang's sculpture will probably stand on the campus of the Polytechnic, and its fame will surpass that of previous presidents, and it will be admired by all Polytechnic students.

Thinking of this scene, Yang Hai's face was extremely ugly.

"Hmph, it's just shit luck!" Yang Hai snorted coldly in his heart, disapproving.

"Even if this +7 valence iron element can bring huge benefits and make Huaxia develop rapidly in the automobile industry, it will be useless!"

"Because, fuel vehicles, will soon be eliminated!"

"That is, it has been developed for more than ten years!"

"When the time comes, it's all electric cars!"

"No matter how good an engine is made out of your steel, it's useless!"

Yang Hai snorted coldly in his heart.

It's just that he forgot that even if fuel vehicles are eliminated, electric vehicles still need gearboxes and chassis.

It's also made of steel!

When the time comes, +7 valence iron will also need to be applied.

"Let's continue testing!"

Ji Chen said, continuing to test all kinds of iron ore from Professor Huang.

Most of the iron ore is tested.

Almost all contain +7 valence iron.

Even the ones that Ji Chen picked up in the valley before.

Since the ores that Ji Chen picked up also had +7 valence iron in them, it seemed very unwise for Ji Chen to spend a huge price to buy those ores in Professor Huang's hands. Because even if you don't buy it, relying on Ji Chen to pick it up, you can still study +7 valence iron.

Ji Chen didn't care about this.

Continue testing.

When the penultimate piece of iron ore in Professor Huang's hand was detected.

"Dididi!"

"Discover something new!, pay attention!"

In the elemental detector, the electronic female voice came out again.

"New element again?" This time, Professor Huang's eyes widened in surprise.

"The new element is -+13 valence iron elemental!"

The elemental detector makes a sound.

"+13 valence iron?"

Another new element of iron!

Professor Huang and Yang Hai were stunned.

They don't know what kind of application this +13-valence iron can have.

"+13 valence iron element?" This time, Ji Chen was a little surprised.

A smile appeared on the corner of his mouth.

"It seems that in the future, the automotive lithium-ion battery industry will become ...... +13 valence iron-ion batteries ......"

Ji Chen muttered to himself.

Neither Professor Huang nor Yang Hai knew the application value of +13 valence iron, but Ji Chen did.

This iron element can be made into iron-ion batteries!
