Starting from a bankrupt steel mill, building a materials empire

All the time.

The body of a car is made up of individual parts welded.

But two years ago.

Envoy Ra introduces the concept of integrated die-casting to the Dragon Kingdom.

With one-piece die casting, all parts are die-cast in one go, and the benefits are unmatched.

The more than 70 stamping and welding parts required for traditional automobile production are simplified into one, and the one-piece die-casting molding can be completed in less than two minutes.

The number of solder joints has been reduced from 700-800 to 50.

At the Envoy La Modu factory, a Model Y rolls off the assembly line in an average of two minutes.

The large die-casting machine can complete a die-casting process in less than two minutes, 80-90 seconds, 40-45 castings per hour, and 1000 castings a day.

To put it simply, the efficiency of producing automobiles with a one-piece die-cast body is greatly improved.

A car body can be produced in a matter of minutes.

The resulting costs are significantly reduced.

A welding factory in a mainstream automobile factory in China is about 200-300 production line workers

With the introduction of integrated die casting technology, the number of skilled workers required can be reduced by at least one-tenth of the original size.

In addition, a large die-casting machine covers an area of only 100 square meters, reducing the factory footprint by 30%.

As we all know, body parts have solder joints everywhere, and when a car collides, they often play the role of bearing and transferring pressure.

Therefore, the quality of solder joints is closely related to the safety of the whole vehicle, and finding spot welding defects is also the key to quality inspection.

The monolithic body, on the other hand, has almost no solder joints and the connection between each of the two planes is absolutely reliable, unless there are unpredictable cracks and damage during the extrusion process.

As a result, the body stiffness of the one-piece body is much higher than that of the welded body during the collision process.

In addition, because welding is reduced, it is possible to reduce weight production.

The weight of the body has also been reduced by 10%.

Reduction of weight,

The result is a reduction in fuel consumption.

In general,

The advantages of a one-piece body are great.

Absolutely

It also has a fatal drawback, that is, once the body is severely deformed after being hit.

The cost of repairs required is very high.

There was a very hot news last year.

An envoy pulls the owner of the car, after the vehicle is damaged.

The maintenance cost of a 280,000 car is as high as 200,000!

It is precisely because of this fatal flaw.

Many companies are waiting and seeing the one-piece body.

Of course.

Various companies are carrying out technology research and development.

An attempt to overcome the fatal shortcomings of the one-piece body.

How to overcome?

As long as the one-piece body is hard enough.

Withstand more force of impact.

This shortcoming can be avoided naturally.

For example, in the face of a pressure of 10 tons, the body of an ordinary car is directly pressed into a piece of iron.

The one-piece body, even if it is damaged, is stronger than the body of an ordinary car.

In He Zhiyuan's view,

Although the Anseong Iron and Steel Plant is capable of producing special steel.

However, it is not always possible to produce the steel required for one-piece car bodies.

"Mr. He, please take a look. "

Li Xu instructed the workers to pull over a piece of steel that had just been produced.

This is related to the fact that the steel has not yet cooled completely.

Li Xu gently clamped it with an iron clip, leaving an obvious mark on it.

"So soft?".

He Zhiyuan was stunned.

But the next moment,

He was directly stunned.

I saw Li Xu instructing the workers to use a few iron clips to pull out a rough car frame with the steel.

How rough is it...... It's the same as a three-year-old's drawing.

I can barely tell it's a car frame.

Then it goes through technical processing,

By the time the frame had cooled down completely, it had become very stiff.

"Get it to the press. "

Li Xu instructed the workers and put the frame on the press.

A press is a type of machine that tests the pressure of steel.

With the air pump turned on.

The press descends slowly.

The pressure plate pressed against the iron frame.

on the counter on the side,

Numbers move fast.

One ton, two ton, three ton......

Soon came the pressure of 10 tons.

And under normal circumstances.

The maximum pressure on the roof of a car is about 10 tons.

The numbers continue to fluctuate.

Just a minute,

That's more than 20 tons of pressure.

Then 30 tons, 40 tons, 50 tons, ......

"This ......

".

He Zhiyuan was stunned.

If it doesn't happen right in front of you

Someone told him about a shoddy body capable of holding 50 tons of pressure, and he would have thought that person was crazy.

After the value reaches the pressure of 70 tons.

Stopped.

It's not that I can't afford it.

The maximum pressure that can be applied by the press at the Anseong Iron and Steel Plant is 70 tons.

"It's incredible......

".

He Zhiyuan finally understood

Why that car accident in the morning,

An old man can be safe and sound between two big trucks.

Such a sturdy body,

Of course there will be no problems.

And most importantly,

This is a one-piece body.

The pressure is higher than that of the old man made by Haile New Energy.

Lower cost and faster to build.

"And lighter!".

He Zhiyuan looked at the car body, his eyes shining.

Because he found out

The steel made of the body is pulled very thin, not even 0.5 mm.

Such a thin body,

And with such high strength and pressure capacity.

The weight is definitely light.

"All the shortcomings of the one-piece body, solved. "

He Zhiyuan was extremely excited.

He didn't expect that,

A technical problem that is difficult for the whole world to solve

It would have been solved in a steel plant in a small county town.

"Great, great!".

He Zhiyuan couldn't be more excited.

He understands very well the importance of the one-piece body in front of him to Piadi.

Piadi has been developing new energy vehicles.

There is a disadvantage of new energy vehicles, that is, the battery has the possibility of spontaneous combustion and self-explosion.

And if the body is hard,

Even if the battery explodes, it will not hurt the passengers.

The safety factor is greatly improved.

"All the problems and difficulties have been solved. "

He Zhiyuan's eyes lit up, and his attitude was very low: "Director Li, please be sure to cooperate with our Biadi Automobile Company, if there are any conditions, you can mention it." "

Li Xu said: "There are no other conditions, because this batch of new steel we are studying has plasticity in a short period of time, so I propose to set up a separate casting workshop in our steel plant, and the steel produced is directly integrated into the casting body, which requires your investment in Biardine." "

He Zhiyuan nodded: "Absolutely no problem, how much to invest, you can mention it, and, when will we sign the agreement?"

Li Xu smiled: "Of course, the sooner the better." "

That's when it happened.

County Magistrate Cui finally arrived.

Without waiting for him to ask,

He learned a pleasantly surprised news: the new Biati Automobile Factory decided to settle in Anseong County, and first invested 100 million yuan in Anseong Iron and Steel Plant, which will arrive tomorrow.
