Siheyuan: After being robbed of her marriage, she married Zheng Juan backhandedly

After the 21st century, my country's crude steel output ranks first in the world.

But the steel rolling technology that really entered the room began in the 70s when my country introduced advanced continuous rolling mills and adopted an automatic control system.

In the mid-60s, what Jinggang could do was only to accumulate volume.

Refining can only be done on very few parts.

Cheng Zhiguo majored in information management at University, so he is not very clear about the history of steel rolling, but he has learned about martensitic steel in an elective course of "Engineering".

This is the steel with the highest strength grade among commercial medium-strength steel plates.

Later aging steel, etc., can even be used in anti-collision bars, aviation, aerospace and marine technology and other fields.

As far as our country is concerned, the level of steelmaking can be achieved, but there is no specific technology.

More importantly, it is exactly what the country needs today.

And on the day when the two eighth-level workers left the factory, Lou Zhenhua received a letter, which contained detailed records of the martensitic steel refining drawings and specific operation methods.

At first, Lou Zhenhua thought that someone was joking with him. After all, this technology was blocked by foreign countries, and no one in China understood it, let alone sent it to him anonymously.

Why, in this day and age, patriotism still hides it?
But even though he thought so, he didn't dare to be careless, after all, this matter was too important.

He asked several experts to come over to check it, and what Lou Zhenhua never expected was that all the experts agreed: it is very likely to be true!
Now Lou Zhenhua couldn't calm down anymore, and pulled all the factory leaders over.

A group of people quickly made a decision to practice once!
Not long after, the workshop with the highest specification was vacated, and all workers above grade six in the factory gathered together.

The whole workshop was a mess, and it was full of famous people from the factory.

If this is handled by a nest, the entire rolling mill will be paralyzed.

The news spread quickly, and all the employees gathered around to join in the fun, regardless of their work.

After all, since the establishment of the factory, there has never been such a big battle, and everyone is very curious about what happened.

Cheng Zhiguo didn't follow the crowd, but went to the tapping workshop.

Xu Weijun is in charge of this workshop.

……

Yi Zhonghai, an eighth-level fitter, is naturally also on the call, and as the only eighth-level worker in the factory at the moment, he has a heavy burden on him. He is responsible for the scheduling of the entire process, the control of the fire, and the forging of the final product.

However, although the burden was heavy, it also made him show his face.

Every leader came up to shake hands and talk, with earnest words and earnest words, as if all hopes were placed on him, and the success of the factory depended on him and so on.

Even though Yi Zhonghai is not young, he is used to seeing all kinds of scenes. At this time, he couldn't help but feel agitated, his face was rosy, as if he had been injected with hormones, he felt that his whole body was full of strength, and he was just waiting to perform well.

"Leaders, please rest assured!"

Yi Zhonghai suppressed the excitement in his heart and promised.

This is simply a credit to the door!

The other two eighth-level fitters were not at home, and the anonymous letter they sent recorded every step in detail. As long as it was true, there was no reason for it to be unsuccessful.

Even if it is fake, the responsibility is not on him.

And once it's true...

Yi Zhonghai looked at the expectant factory leaders around him, and the workers who were crowded around the workshop door, and his heart was surging.

This is simply his highlight moment!
Wherever you go in the future, whoever meets you can't call Master Yi?

Moreover, judging from the importance attached to this steel by the factory leaders, it must be a big deal when this thing comes out, so this honor cannot be lost!

Salary increase?
He doesn't pay attention to small things.

"Lao Jia, Lao Zhao, who told you to go out at this time, it's unlucky for you..."

Yi Zhonghai sighed secretly, walked to the boiler with arrogance, and waved his hand:
"start!"

The whole workshop suddenly became agitated.

Liu Haizhong is a seventh-level fitter, and he can be regarded as a person in normal times, but at this time he can only help out, and was arranged by Yi Zhonghai in a place where he does real work.

If you want to say that although the courtyard is the most respectful of face and good official prestige, it is undoubtedly him.

So seeing Yi Zhonghai show off the limelight now, he really feels bad in his heart.

Made.

This old guy has done so many bad things in the past two days, God would have struck him with a thunderbolt, and even thrown him a pie.

It's really unreasonable.

It is estimated that after today, my life will be even more difficult.

The principal of the courtyard house is definitely out of business, and the issue of the workshop's treatment may also be suppressed for a while.

Heaven has no eyes!
He looked at Yi Zhonghai who was the focus of attention, and couldn't help cursing in his heart.

"Temperature adjustment, 400 to 450 degrees."

The temperature requirements of martensitic steel are extremely important. The refining stage requires three steps. The temperature and fire requirements in the three steps are very precise. In the case of only manual intervention, the technical requirements for workers are very high.

Yi Zhonghai commanded nervously while looking at the blueprint.

Whether he can become famous in one battle depends on this time, he naturally has to work hard.

"Temperature adjustment, 600 degrees to 750 degrees..."

Half an hour later, the molten steel came out of the furnace, and Yi Zhonghai quickly directed everyone to hot-roll, cold-roll, and then mix it.

After another half an hour, the first forged steel was finally ready.

Yi Zhonghai did it himself, controlling the forged steel hammer.

"Boom!"

"Boom!"

The rhythmic pounding of the machine was like hitting everyone's hearts, raising their nervousness little by little.

Lou Zhenhua clenched his hands together.

Whether it will be successful or not depends on now.

Martensitic steel has a very high status in steelmaking, and plays a pivotal role in a country's national defense and heavy industry.

Once successful, it will be of great benefit to his current situation.

"That's my master!"

Qin Huairu pointed at Yi Zhonghai, who was attracting everyone's attention, and said to the people next to him braggingly.

"is it?"

The people around curled their lips secretly, but they couldn't hide their envy on their faces.

One person ascends to heaven and attains Taoism.

Yi Zhonghai has shown his face in the factory this time, and his apprentices will probably rise in popularity in the future, and become the sweet pastry that all workshops are vying for.

Qin Huairu, a first-class worker, also got a big deal.

"Bang!"

At this moment, a dissonant harsh sound sounded amidst the even impact.

"Break--"

The forged steel controlled by Yi Zhonghai broke, and one part was still clamped in the pliers, while the other part hit the ground heavily!
