Siheyuan: Concentrate on arms, Eagle Sauce is frightened

Chapter 126: The Heat Wave Rolls, and the First Furnace of Special Steel Comes Out [Ask for flowers, ask for evaluation votes.

This kind of thing.

Yang Jianshe is also now the director of the steel mill.

Naturally, it is impossible to miss.

So, the first thing to do is to go to the steel mill and see the situation.

After cleaning up, I got up and went to the steel mill.

At this time, the steel mill is full of lights, big red lanterns and red flowers.

It looks especially festive.

Except because it was just after the New Year.

The main reason is to celebrate the refining of the first furnace of special steel.

Recently, the steel market has been sluggish, and its own products can only be sold by relying on low-price competition. Inside the steel mill, many people are clear.

Later, Yang Jianshe came over and merged the steel mill with the rolling mill.

This makes many old steelmakers actually feel more embarrassed in their hearts.

I was afraid that after that, the director of the plant changed his appearance.

However, the steel mill still focused on its own business and continued to make steel. And, success requires the first furnace of special steel.

The confidence of many people was lifted by this.

After Yang Jianshe arrived, he saw Wang Lihua, the deputy director of the factory, and a group of people greeting him early at the door.

In hand, he also holds a banner.

Welcome to Yang Jianjian.

The joy is beyond words.

“Director Yang, you came just right!”

“Soon, the first molten steel furnace will be converted.”

“The task you told us before should be completed!”

After getting off the car, Wang Lihua enthusiastically took him and went to the steelmaking workshop after putting on protective clothing.

In the steelmaking workshop, there is a heat wave at the moment.

The temperature has reached almost 40.

A lot of people are nervous, looking forward to it.

The first furnace of molten steel is about to come out.

“Director Yang, after the molten steel is just out of the oven, the temperature will be very high, do you want to go out first?”

“Wait a while the temperature will come down, and then take a look?”

Wang Lihua took a look at Yang Jianjian.

He was afraid that Yang Jianshe had not experienced this situation, and he was heated for a while.

“No need, I should be fine.”

“There are a lot of steelmakers next to me, they can withstand it, I’m so far away, what am I afraid of?”

Yang Jianjian rebuffed his words, his current body was not afraid of this temperature at all.

What’s more, he himself was also more curious, so he stared motionlessly at the molten steel.

I saw a huge tank-like furnace, under the control of the steelmakers.

Slowly tilting, the furnace opening and pouring molten steel outward.

The temperature of molten steel just baked is about 1700.

The fiery hot molten steel was poured into the steel drum.

Not only is the temperature high, but the appearance is also very frightening, like the sun being punctured and leaking liquid.

Suddenly, a heat wave was stimulated.

The workshop, which was already relatively hot, was directly raised by two degrees as soon as this molten steel was stimulated.

“Goo, goo.”

The molten steel fluctuates in the steel drum.

That color, bright enough, scorching fire, as if to pierce people’s eyes.

After smelting molten steel, this is not over.

Next, under the skilled operation of the workers.

Go to the next step. Converter steelmaking.

Because this is the first furnace of molten steel, there are still many impurities in it.

If used directly, the impurities are not purified.

It will cause the steel structure to be unstable, especially it is easy to crack or something.

Converter steelmaking to remove impurities.

The scalding molten steel was poured out again.

Normally, this step can already be completed.

As long as it goes to the mold for cooling, it can be sent to the rolling mill for rolling.

Qualified steel can be formed to leave the factory.

But because of this furnace, special steel is refined.

Especially used in ships.

The requirements for steel are particularly stringent.

You can’t be sloppy.

Therefore, the refining of this special steel is to have one more step.

That is to continue refining a little more.

Again, the molten steel was added to another furnace.

This time the step.

Mainly to add some other metals, as well as some non-metallic elements.

Let the ingredients combine with each other.

In this way, the steel smelted can be more stable, and the quality of all aspects can be greatly improved.

The quality is also raised a notch.

Due to the steel produced by the previous steel mill, there is no special steel, basically ordinary steel.

Therefore, there are only two steps, after removing impurities, you can leave the factory. There is no need for refining in a refining furnace.

This is the first time they have used this refining furnace, and it is still a little rusty.

Yang Jianshe looked at the workers and compared the type of steel that needed to be added0.

Carefully add some other metals and the like to the refining furnace.

After adding them, wait for them to melt away.

Under the stirring of the internal machine, it is integrated with the original molten steel.

After a while.

It’s not like just now, dumped in a steel drum.

Instead, slowly, little by little, it pours on top of the mold.

Come out piece by piece of billet.

Since the second steelmaking plant is purely steelmaking, it has no function of rolling steel.

In their factory, that’s done.

The premise is that the billet passes.

Since a refining furnace had never been used before, it had never been made of special steel.

Whether it can succeed or not, so many people actually do not have too much bottom in their hearts.

Now, in addition to Yang Jian.

Everyone is nervous.

I don’t know if I can make good steel.

If there is a defective product, it is bad.

After the billet has cooled down.

Wang Lihua was overjoyed when he saw the hunter, and quickly rushed over with Yang Jianjian.

He picked up this billet.

Turn over and over again.

He also held a small hammer and struck it.

The billet makes a “ding” sound.

Wang Lihua was amazed at this.

In his eyes, he was even more full of joy.

“Director Yang, look at this billet, it’s just perfect!”

“I can’t see any impurities, knock it up, and the sound is no problem at all!”

“Just by looking at it, I know that almost 5.4 is no problem!”

“Of course, you still have to go through testing to know the specific situation.”

Wang Lihua was excited and said again and again.

Yang Jianjian smiled: “Everything is difficult at the beginning, this is considered the first furnace to form.” ”

“I believe there should be no problem.”

The billet is taken to the inspection department of the steel mill for inspection.

Such as hardness, flexibility, resistance to blows, etc………… It will take a little more time.

Because it doesn’t take long.

So Yang Jianshe chose to wait at the steel mill for a while.

Because this steel mill does not include the function of rolling steel.

After the inspection is qualified, then you can call the car directly.

These billets are pulled to the rolling mill for rolling.

At that time, you can really leave the factory.
