Starting from a bankrupt steel mill, building a materials empire

Aircraft carriers have very high requirements for steel.

For example, the deck of an aircraft carrier.

It is necessary to carry a strong impact force and high friction force for the take-off and landing of carrier-based aircraft.

It also endures the flames of jet planes up to several thousand degrees Celsius.

Therefore, special steels with high temperature resistance, impact resistance, high strength and high toughness are needed.

This special steel,

Originally, there were only three countries in the world that could produce it.

Two years ago, the Dragon Kingdom finally broke through this key technology.

It became the fourth country that can produce special steel for aircraft carrier decks.

And this is just one special steel that aircraft carriers need.

The steel needed for the bottom of an aircraft carrier is exposed to seawater corrosion and torpedoes.

Therefore, special steels with excellent corrosion resistance and impact resistance are required.

And it can't be too thick.

If it is too thick, it will cause the weight of the entire aircraft carrier to increase significantly.

Affects the speed of the aircraft carrier.

Generally speaking, the thickness of steel required for the bottom of the aircraft carrier is between 150~230 mm.

This piece of steel sent by Li Xu.

Although the corrosion resistance is somewhat worse.

But strength, toughness and high temperature resistance, no problem at all.

Although there is no way to use it as steel for the bottom of the aircraft carrier.

But it can be used as a different part entirely.

Therefore, Academician Xue Shuzhen was very excited.

The third aircraft carrier of the Dragon Nation has been launched.

The fourth aircraft carrier has also been approved for a long time.

Construction is in full swing.

But.

In recent years, Western countries, especially beautiful countries, have imposed more and more sanctions on the Dragon Kingdom, which are becoming more and more serious.

Some special steels cannot be imported at all.

Other than that.

This is the fourth aircraft carrier of the Dragon Country.

The state wants to go further.

There are some innovations in some technologies.

Among them, reducing the weight of the aircraft carrier itself is the top priority.

The aircraft carrier itself is lighter, not only sailing faster.

And with the same displacement, carrier-based aircraft, fuel, and living supplies are carried more.

To

reduce the weight of the aircraft carrier itself, the most fundamental thing is to use thinner steel to achieve the same effect.

For example, 200 mm of special steel would have been required.

If you can use 150 mm of special steel, you can achieve the same high temperature resistance, corrosion resistance, impact resistance, and high strength.

Doesn't it reduce its own weight?

In the past three months, Academician Xue Shuzhen has led the team to study day and night.

Unfortunately, not much progress has been made.

"This kind of steel is not only stronger, but also reduces the thickness. "

Academician Xue Shuzhen couldn't sleep all night.

Although samples were received.

But he is also concerned that the steel plate was not produced by the Anseong steel plant.

It was Chen Fan's classmate who didn't know where to get a piece of special steel to fool him.

"I'm going to go myself. "

......

Early the next morning.

Academician Xue Shuzhen convened the researchers in the team.

Told me about it.

"Chen Fan and I will go to Ancheng County, and you will stay here and continue to study using Baosteel's equipment and materials. "

Xue Shuzhen commanded.

"Teacher, don't worry, leave it to us here. "

"Professor Xue, you can rest assured. "

The rest of the research team said.

Academician Xue Shuzhen and Chen Fan hurriedly went to Ancheng County.

Others stayed at Baosteel and continued their research.

Baosteel.

The largest steel plant in the Dragon Country, there is no one.

Whether it is technology or scale, it is the first in the country.

Baosteel has a dedicated research laboratory for steel materials.

Du Mingcai, the director of the laboratory, is the chief engineer of Baosteel.

He cooperated with researchers from the National Institute of Materials Technology and Engineering to study special steels.

"Professor Gao, why didn't Academician Xue come today?"

Du Mingcai asked curiously.

Academician Xue Shuzhen is obsessed with scientific research.

Since taking over the project of special steel research.

Sleepless nights.

Coming over every day.

"There is a steel mill that sent a piece of special steel, saying that they can produce special steel, and Professor Xue went to see it today. Professor Gao explained.

"What steel mill?".

Du Ming was even more curious.

Since the restructuring of the steel industry more than 10 years ago.

Baosteel has acquired many large steel mills.

It can be said that

Baosteel's branches are all over the country.

At the same time, Baosteel is also one of the few steel mills in China that can produce special steel.

"Is it Angang?".

Du Mingcai guessed.

"It's not. Professor Gao shook his head, "It's a steel mill in a county town...... It seems to be called ...... By the way, Anseong Iron and Steel Plant, have you heard of Professor Du?".

Du Mingcai thought about it carefully.

Sure haven't heard of the name.

It shows that the other party is a small steel mill with a small name.

"How is it possible? It is absolutely impossible for a steel mill in a county town to produce special steel. "

Du Mingcai didn't believe it at all.

On the contrary, I think that Academician Xue Shuzhen is making a big fuss.

"Chief Engineer Du, there is a high-level meeting at 9 o'clock today, and you need to attend. "

A phone call came.

Du Mingcai: "I know, please send me the content of the meeting and the address of the meeting room." "

Hang up the phone.

Du Mingcai said: "Professor Xue, I have a meeting, please do your research first." "

Professor Xue: "No problem. "

......

Baosteel, Conference Room 701.

Du Mingcai looked at the materials in his hand and was very puzzled.

There were several topics on the agenda of the meeting.

All other topics are normal.

There is only one issue, which is very unusual.

Biardi Automobile Company terminated its cooperation with Baosteel.

All the time.

Baosteel is the steel supplier of Piardi Automobile.

It is an important customer of Piardi Automobile Company.

"Why?".

Du Mingcai was very puzzled.

"Our bid is not high, and the quality of the steel is guaranteed, and Piardi is in the midst of an explosion of business, so why not use our steel?".

The vice president who presided over the meeting said: "As far as I know, they have found a better steel supplier, which seems to be able to supply special steel, and it is a one-piece cast body. "

"Chief Engineer Du, let you attend the meeting this time, is to renovate our steel. "

"Now the ordinary steel market is saturated and piled up, and only by producing more high-quality steel can we occupy the market. "

Although Baosteel is the largest steel mill in the Dragon Kingdom.

But life is not easy.

This time,

Biardi Motors terminated its cooperation.

It has a direct impact on their sales this year and beyond.

"How is that possible?".

Du Mingcai shook his head frantically.

Cars are made of special steel

When did special steels become so common?

Truly.

In automobile manufacturing, a part of special steel is required.

However, the amount required is small.

Most of them are still ordinary steel.

And Biadi terminated the cooperation,

Meaning, they don't even need ordinary steel anymore.

Is it all made of special steel?

"Are they crazy?".

"By the way, which steel mill is their new steel supplier?".

The vice president of Baosteel thought for a while and said, "Anseong Iron and Steel Plant." "
