Siheyuan: Craftsmen of a Great Country

Two furnaces a day speeded up the experiment a lot.

At noon on New Year's Day, all three furnaces of tungsten steel required for the experiment had been refined.

Lu Yuehua is indeed a fanatic, and he hardly gives himself any time to rest.

While waiting for the last batch of tungsten steel to cool down, Lu Yuehua arranged for the refining of chromium steel.

After waiting for the molten steel to cool down, he and Jiang Chen began to calculate the optimal ratio of tungsten.

Since Jiang Chen had set the ratio range for the experiment in advance, the two quickly calculated the same result—the theoretical optimal ratio of tungsten elements in tungsten steel.

The reason why this is theoretical is because the ratio of tungsten elements in tungsten steel is not equivalent to the content of tungsten steel.

By conducting several experiments around the theoretical optimal ratio, we can obtain a value that is infinitely close to the optimal ratio.

This value can be used as the optimal ratio. The slight error in the middle will have little impact on the overall result and is within the acceptable range.

What's more, there is a cheater like Jiang Chen, so in the final experiment, there must be a furnace of steel with the best ratio.

Looking at the calculation results, Lu Yuehua said happily: "Director Jiang is so powerful and domineering. We are heading in the right direction."

"Now we only add a single element of tungsten, but the quality of the steel produced has exceeded the original data provided by the Sichuan Steelmaking Plant, and far exceeds the quality of existing steel."

"It has higher hardness, more wear resistance, better strength and toughness, and the heat resistance and corrosion resistance have also been greatly improved. It remains basically unchanged at a temperature of 500c and still has a high hardness at 1000c."

“When tungsten and chromium are truly combined to create alloy steel, its quality will definitely far exceed the quality of current steel.”

Jiang Chen smiled and said: "Theoretically it should be like this, but don't be too happy too early."

"Because we are still not sure whether the combination of these two alloys will have a positive or negative impact on the quality of steel. Maybe the price of chromium will be lower than the quality now."

Lu Yuehua nodded: "It is possible, but I believe that the two alloys added together will definitely make the quality higher."

Jiang Chen smiled and said, "Oh, are you so confident?"

Of course he knew that the combination of these two elements would make the steel higher quality.

Lu Yuehua said: "Ahem, I have nothing to worry about when I got home. I quietly calculated again. According to a certain decline curve, I reduced the tungsten element ratio used in our experiment to the point where the natural content in the water is equal. The quality of the steel is not as good as that of Sichuan. Refined on the side."

"So the chromium element must have played a positive role. Of course, I was just playing around with it when I had nothing to do. I also added the concept of adhesion rate. Although it is not accurate, it should not be wrong."

"Bar!"

It can be seen that he has no confidence either.

In fact, he was just too excited to take any time off. Even though he knew it was useless, he still couldn't help but want to do some calculations.

Just like the novels written by Pujie in later generations, I know that the collection recommendations are not of much reference value, but I still want to read them at any time.

Jiang Chen did not answer the question: "When the experimental results come out, you will know at a glance."

Lu Yuehua nodded: "Okay!"

"Director Jiang, I think you are good at everything, but you are too calm and have no passion at all."

Jiang Chen smiled and said: "You can be emotional when you are an executor, but you must be calm when you are a manager."

"I was impulsive and a wrong decision could cause losses to the country."

Lu Yuehua waved his hand: "I'm not saying that it's not good for you to be like this, I just think that people are not frivolous and young. They are too calm and lifeless, like a little old man."

At noon on New Year's Eve, the second furnace of chromium steel is being refined.

"I have something to do and may have to come back later. You can just make steel as planned." Jiang Chen explained, then left the steel-making furnace and headed to the factory director's office.

Yang Weimin looked up from a pile of documents: "Is something wrong?"

Just after the New Year is his busiest time.

Jiang Chen nodded: "Don't you want to make alloy steel? I specially called someone from my hometown who had been involved in the refining of special steel."

Yang Weimin smiled and said, "Is he your cousin? Which department do you want to arrange for him to join?"

"Although rural household registration is a bit troublesome, after all, they are skilled workers with experience in steelmaking. Your laboratory is doing research in this area and should be useful. Lao Tao and I can think of a way and we can still arrange it."

He misunderstood what Jiang Chen meant and thought Jiang Chen came to him to arrange a job for Zhang Huajun.

They even wanted to place him in a laboratory with the best benefits.

Although this matter is troublesome, Yang Weimin and Tao Yuan can still think of a way if they really want to arrange it.

It is not difficult to arrange one person for two department-level cadres.

Jiang Chen waved his hand: "That's not what I meant. We will consider his work issues later. It's just that he brought a lot of things when he came here this time, and it was inconvenient to catch the bus."

"So if it's convenient, could you ask Master Yang to come with me and pick him up from the train?"

Yang Weimin was stunned: "That's it?"

Jiang Chen nodded: "Yes, if it's inconvenient, I will"

After all, it is a public car, so it is not good for private use.

So Jiang Chen found a justifiable reason.

Yang Weimin said: "You come to me for such a stupid thing, you are so idle. Just tell Xiao Yang and ask him to go with you."

"Go ahead, I'm busy."

Jiang Chen nodded: "Okay!"

After leaving the door, he went straight to the side to find Xiao Yang.

Xiao Yang didn't say anything, didn't even ask Yang Weimin for instructions, and drove Jiang Chen straight to the train station.

At the entrance of the train station, Jiang Chen threw a cigarette to Xiao Yang, opened the window a little, and puffed away in the car.

It was still freezing cold in Sijiucheng in February.

If you get out of the car and smoke, you are asking for trouble.

Although Jiang Chen's current body is not afraid of the cold, he is still used to staying in a comfortable place.

Soon, a large number of people walked out of the station, and the train from Chengdu arrived at the station.

Jiang Chen got out of the car, tightened his clothes habitually, and stood on the roadside.

He is tall and has an obvious target, making it easier for Zhang Huajun to see him.

But this time it was Jiang Chen who discovered the other party first.

Because he is so conspicuous, even without eagle eyes you can see him at a glance.

There was a large linen bag on his left shoulder, which was held in place with his left hand. .

His right hand was bent to his shoulder, holding the opening of a linen bag, and apparently there was another one on his back.

From far away, you can smell the faint scent of bacon.

Zhang Huajun was pressed so hard that he couldn't straighten his waist. Jiang Chen said, "Xiaojun, this."

Then he walked forward quickly: "Why are there so many? Come on, give me a pocket on your back."

He staggered his body and reached out to pick up a bag on his back.

Before his hand even touched the pocket, he saw Zhao Qi behind Zhang Huajun, who was helping him carry the pocket.

Zhao Qi smiled: "Jiang Chen, long time no see!"
