Siheyuan: Cooking journey

It's bizarre that I understand stainless steel welding rods. They are two completely unrelated things.

And, most importantly,

In China, the manufacturing technology of stainless steel welding rods is almost blank. If it comes out of nowhere, it will definitely cause a sensation. We have to think about how to make stainless steel welding rods quietly without causing trouble. Otherwise, once the dough mixer is unveiled, there will be experts who are curious about how stainless steel barrels are welded and where the stainless steel welding rods come from. That will be a big trouble. This thing cannot be made secretly by ourselves, and we have to find a reason to cover it up.

After Director Yang left,

He Yuzhu thought for a long time and came up with an idea. He wrote down the manufacturing process of stainless steel welding rods in detail.

The most critical part of this process is the coating of the welding rod.

Although the ingredients that make up the coating are not many, the proportion has to be explored bit by bit through countless experiments, and there is no shortcut.

It's like cracking a six-digit password, you have to try each number.

It is even harder than decrypting the code, because there are far more than ten types of elements, and there is no other way except trial and error.

The process data has been finalized.

A few days later,

He Yuzhu said hello to Director Yang on the pretext of going to Siji Changqing, and went to Jincheng to throw the information out anonymously. The handwriting was the same as the previous drawings, and it was cleverly modified with the painting skills.

The information is detailed, and with the existing welding rod production line, the finished product can be made in a few days according to the efficiency of the current workers. However, in order to be safe and avoid suspicion, I would like to wait for the other party to verify it.

He Yuzhu waited for another month.

No one will immediately believe a piece of information of unknown origin, but once they see the information, those who know the subject will definitely do experiments with a verification mentality. As long as the experiment is successful, the true and false will naturally become clear.

Of course, testing is testing.

It is also possible that you do not trust the information at all and just throw it away without even trying it.

After all, at that time, everything was based on steel, and stainless steel was not widely used. Researching stainless steel welding rods was not a pressing matter. There was a project under research, and there was no strict requirement on when to produce results.

Because the things that are researched are not necessarily better than imported ones. Even if the most advanced welding rods in the world are not used, they are useless.

More likely, like refining stainless steel, although it is not needed temporarily, the company's own warehouse has enough of this stuff, so it makes sense to "save face".

one way or another,

A month has passed.

It's time to get some information.

He Yuzhu went to see Director Yang.

"Director, I've thought about it and it would be a shame to give up the dough mixer after it has been developed to this stage.

"Didn't you say last time that the stainless steel welding rods independently developed by the welding rod factory?

“Even if there are many problems and the welding is not strong enough, we can weld it a few more times. It is better than giving up.

"Besides, it's just kneading dough, not a sophisticated industrial product. There are no special requirements. Just don't leak the batter. Can you help me get the latest research results of the welding rod factory, and let's try it...

"..."

A few more days passed,

The dough mixer was finally assembled and put into use.

He Yuzhu felt both relieved and tired.

It’s so difficult to do anything right now.

From stainless steel to heating furnace, to stainless steel welding rods, nothing is easy.

Fortunately, everything was solved and the dough mixer was successfully launched.

He Yuzhu made up his mind to be a cook and not get involved in anything else.

As a result, just a few days after the innovative results were reported, reporters came directly to the door.

There were photo taking and interviews.

He Yuzhu had anticipated this.

These days people like to set up examples and learn from visits.

I just underestimated the influence of the dough mixer.

It was on the front page for three days in a row and was played non-stop on the radio.

All the factories in the city that have canteens organize people to visit and learn.

The canteen of the steel rolling mill has turned into a zoo.

I saw the effect of the dough mixer with my own eyes.

The dough mixer has become the most coveted equipment in every canteen.

Each factory should have careful discussions with the steel mill.

There is no other way, only steel rolling mills have the ability to make this.

He Yuzhu watched silently from the side, and his idea of ​​becoming a small chef became more determined.

Of course, all this has nothing to do with him. The head of the innovation team is Director Yang. He is the one who takes the lead and reports the example.

He Yuzhu took the 300 yuan innovation reward and quietly became an unknown person.

At the same time, I was secretly glad that I didn't become the leader of this innovation group.

Otherwise, if he were to be so prominent at such a young age, I don’t know how many people would be jealous of him.

It is easiest to get into trouble when you are at the peak of your popularity.

The craze for dough mixers lasted for a few months and finally cooled down.

He Yuzhu just breathed a sigh of relief, thinking that the cafeteria was no longer a zoo, but he found that the steel mill was even more lively.

There are endless groups of people coming here every day.

However, the target of this visit was no longer the canteen, but the hot rolling workshop.

Later, more and more people came.

He Yuzhu roughly guessed that they were here to see the heating furnace.

As for that!

This heating furnace is not much better.

I was puzzled and asked Director Yang when he came to the cafeteria.

Director Yang said with emotion:

"Xiao He, you don't know how great the old professor's contribution is. I am really unworthy of such a great achievement.

Big contribution?

This heating furnace hasn't improved much.

He Yuzhu was puzzled, frowned slightly, and tried to ask:

"Is this heating furnace good?"

"Okay, great."

Director Yang nodded solemnly, knowing that he didn't understand, and explained:

"Remember what I told you before?

The steel billet is heated to a specific state in a heating furnace. It should not be too soft or too hard, but should be burned through.

It's like cooking noodles. The heat must be just right so that the noodles are chewy and delicious. They cannot be overcooked, nor can they be undercooked.

In the past, the temperature of the heating furnace was difficult to control. We knew that the steel billet had to be heated to a specific state, but it was difficult to operate.

In most cases, the steel is overheated, and there is nothing that can be done about it. If it is not burned through, the hot rolling mill cannot roll at all, so it has to be overheated and then cooled down.

As a result, the quality of the steel after rolling is very average or even unqualified.

But this heating furnace is different. It has stable temperature, uniform heating and easy control. The steel billet is burned just right when it passes through it.

After multiple rough rolling and final finishing rolling, each piece of steel obtained has top-notch indicators and the best quality.

In the past, our rolling mill could occasionally produce steel of this grade, but it was purely a matter of luck.

It's not just our steel mill, it's the same all over the country. If the higher-end steel is needed, the steel mills can only piece it together.

Now, our rolling mill can produce this steel stably;

This is a huge achievement;

I just received a notice that the heating furnace will be upgraded nationwide. Every steel rolling mill must come to us to learn. In the future, we will no longer lack good steel...

After listening to Director Yang's explanation,

He Yuzhu didn't know what to say for a moment.
