Starting from a bankrupt steel mill, building a materials empire

The person in charge of the base received an order from his superiors to prepare for the test launch of an intercontinental missile at a desert island in the Pacific Ocean.

"Ah, how is this time!!".

The person in charge of the base panicked.

It turned out that a new situation had arisen at the missile launch base.

It goes back a year.

As we all know

Although the economy of the Dragon Kingdom is changing with each passing day, it is developing rapidly.

But after all, the background is very shallow.

For a long time, some important equipment needed to be imported.

For example, engines for large aircraft, missiles, and rockets all need to be imported.

However, with the continuous investment of state funds and talents.

The situation has improved considerably.

The housing of a solid engine not only needs to withstand very high pressures, but also requires a very low weight.

The technical requirements are very high.

After the research and development of scientists, a high-strength filament-wound composite material was finally developed, and the localization of the missile engine shell was realized.

However, there are still some other technical difficulties that have not been overcome.

The most representative is the swinging nozzle.

The swinging nozzle is a key part of the missile's first-stage engine.

It needs to be able to withstand high pressures and temperatures.

In particular, there are extremely high requirements for the tightness of the spherical surface of the swinging nozzle.

So a year ago, experts led by Liu Yang, an academician of the Academy of Sciences, began to study the swinging nozzle.

And successfully achieved a technological breakthrough.

Succeeded in localizing the oscillating nozzle.

The latest production of the Nanfeng 41 intercontinental missile uses this domestically produced swinging nozzle.

However, just a month ago.

Some domestic swing nozzles have spherical ruptures.

Liu Yang and other scientists urgently tackled key problems.

It was found that the materials used could not cope with the high levels of stress.

In this case, there are no technical defects.

It's that there is a problem with the material.

It's not even sure if all domestic swinging nozzles have problems.

So it needs to be replaced all.

But here's the problem.

Now there are no enterprises that provide steel materials that meet the technical requirements.

And because the engine has undergone technical iteration.

There is a mismatch between foreign imports.

Now the situation is very awkward.

in the laboratory.

The person in charge of the base looked at Academician Liu Yang with a blank eye, "Professor Liu, can you solve that technical problem within three or five days?"

Academician Liu Yang was already in a bad mood, and he was about to explode when he heard this.

He glared and said: "Leader, the problem of technical research cannot be solved in three or five days, and no one can guarantee how long it will take, maybe three or five months, or three or five years." "

The person in charge of the base was suddenly heartbroken, "It seems that I can only report!".

The situation will soon go to the top of the military.

High-level military meetings are held.

Vice Minister Gu of the Logistics Department also attended the meeting.

At the meeting, everyone was thinking about what to do.

"If it really doesn't work, I'll launch other types of ICBMs. "

"It's a pity!".

"Yes, the Nanfeng 41 ICBM is the most advanced ICBM in China, and it has a stronger deterrent power. "

Vice Minister Gu listened for a while, understood the truth of the matter, and took the initiative to speak: "Everyone, in fact, things still have a turning point. "

"Oh, do you have a way?" asked the minister.

Vice Minister Gu nodded: "Everyone must already know that a magical enterprise has recently emerged, the special steel used in the fourth aircraft carrier, and the stealth absorbing materials that have just been in the limelight, are all produced by this company." "

"In that case, why not give their special steels a try?"

After hearing this, the minister suddenly realized: "Oops, I almost forgot about this." "

In fact, it is mainly because of the two products produced by Anseong Iron and Steel Plant, although they are powerful, but because they appeared too suddenly.

A lot of people don't know about it.

At the first time, I didn't think of the special steel produced by Anseong Iron and Steel Plant.

"Lao Gu, you are responsible for contacting this matter. "

"No problem. "

After the meeting.

Minister Gu first contacted Liu Yang, an expert at the missile base, and told him about the incident.

Liu Yang was overjoyed.

Because of the secrecy of the construction of the 4th aircraft carrier.

He didn't know much about the process.

Now that I know it, my hope grows.

Immediately sent the drawings of the swinging nozzle to Li Xu through Vice Minister Gu.

After Li Xu got the drawings, he asked the workers to make a mold.

An hour later.

A one-piece oscillating nozzle was produced.

All of the special steel used is S-grade.

High temperature and high pressure resistance, as well as sealing performance, are all first-class.

"It's done, do you send someone to pick it up, or do you mail it?"

On the same day, Li Xu called back Vice Minister Guo.

"Haha, I knew that Director Li would not let me down. "

Vice Minister Gu was overjoyed, "I'll send someone to get it." "

Li Xu delivered a total of 100 swing nozzles.

One is worth 100,000 yuan.

In fact, the cost of the materials used is only 10,000 yuan.

The difficulty lies in the casting of one piece.

The oscillating nozzle is molded in one piece, and the sealing performance is very good.

Plus the special steel strength of the S grade.

There will be absolutely no cracking.

Of course.

If other businesses want to reach this level.

100,000 yuan is far from enough.

This is also the reason why the international price of a swing nozzle is 1 million yuan.

And it's priceless.

It is an international strategic embargo.

Ordinary countries can't buy it if they want to.

A day later.

A missile base in the northwest.

Academician Liu Yang looked at the shiny swinging nozzle with a look of surprise.

Although it has not been tested, it only looks good.

These swinging nozzles are much stronger than the ones he studied before!

"Hope to pass the test!".

Academician Liu Yang organized manpower to conduct the test as soon as possible.

Perform a high-temperature test first.

The temperature of the Spitfire in the tail of the missile is around 2000 ° C.

The temperature of the Nanfeng 41 ICBM is a little higher, reaching 3500°C.

So the oscillating nozzle can withstand a temperature of at least 3500°C without damage.

As the temperature of the laboratory increases.

Flames of up to 3,500°C scorched the oscillating nozzles made of special steel.

The swinging nozzle is unharmed.

"Increase the temperature to 5000°C. "

Academician Liu Yang said excitedly.

Soon, the temperature in the test chamber increased to 5,000 degrees Celsius.

The swinging nozzle still shows no signs of damage.

Liu Yang is also determined.

"Great!".

After that, a pressure test, a tightness test, was carried out.

The oscillating nozzle passed all tests perfectly.

A day later.

Liu Yang also found the person in charge of the base: "The problem of swinging nozzles has been solved, please tell the leader that the intercontinental missile can be launched." "

That day.

When answering reporters' questions, the spokesman for the defense of the Long State officially reported:

Two days later, the Dragon Kingdom will test-launch an intercontinental stealth missile.

Destination, the deep sea of the southern Pacific Ocean.

And on the official website, the approximate route was posted.

One of them passed over three military bases in the beautiful country.

The implications speak for themselves.
