Siheyuan: Craftsmen of a Great Country

In the afternoon, Jiang Chen found Wan Li and began to draw a schematic diagram of the converter.

"The uppermost end of the converter is the furnace mouth, which is divided into three sections: furnace cap, furnace body and furnace bottom from top to bottom."

"The straight-mouth furnace cap is axially symmetrical in the shape of a truncated cone, the furnace body is in the shape of a straight cylinder, and the bottom of the furnace is in the shape of a spherical gap."

"The furnace shell should use the alloy steel we just developed as the raw material. After all, it has high strength and better temperature resistance. During our experiment, we produced a lot of semi-finished alloy steel, which is enough to make a medium-sized converter."

"The fireproofing material should be alkaline. It is tentatively decided to use dolomite bricks plus magnesia carbon bricks."

"There is a support ring at the bottom of the converter, which plays the role of supporting the furnace body and transmitting the tilting moment. The cross-section is rectangular, with a perforated rib plate standing upright in the middle to increase the stiffness of the support ring."

"There are trunnions on both sides of the support ring. The trunnions are supported on bearings and driven by gears."

"No, no, the function of the trunnion is to tilt the furnace body through the support ring, which is convenient for mixing molten iron, adding scrap steel, sampling, tapping and pouring slag. To make the converter rotate, it cannot be a dead structure like this."

“We need to use a suspended reduction system, that is, hang the reducer and motor on the trunnion, and always maintain a vertical relationship with the trunnion, so as to avoid the bending deformation of the trunnion and the supporting ring, which will cause the internal gear of the reducer to not mesh well, and increase the Wear and tear.”

"The tapping port is at three-quarters of the height of the furnace body. After tilting, the molten steel flows out from here and enters the container."

"The water-cooled oxygen lance is fixed in the center of the intersection, and oxygen is blown into the converter."

The two of them first worked together to draw an overall schematic diagram of the converter, and then began to draw subdivided schematic diagrams of important components.

Since converter steelmaking has successful precedents in the West, Jiang Chen did not hide it and directly gave the correct converter structure and parameters.

While Wan Li was drawing a picture, he said: "Director Jiang, according to your size, your converter is not small. A single furnace can hold 200 tons of steel, right?"

Jiang Chen smiled;

"This is the volume, but it does not mean that one furnace can produce so much steel. In actual operation, only about one-seventh of the area can hold molten steel, and the rest must be empty to accommodate foamed slag and avoid splashing."

"So this furnace can produce about 30 tons of steel per furnace."

This test is different from the development of alloy steel.

Alloy steel just needs to get the right ratio, so there is no need for a test furnace with too much output.

However, converter steelmaking is the study of steelmaking methods, and various parameters will change as the output of the furnace changes. Therefore, converter steelmaking experiments cannot use too small a furnace.

Of course, there is no need to make it too big, so Jiang Chen compromised and chose a 30-ton steel-making furnace.

By the time I finished drawing the design drawings of the converter, it was already time to get off work.

Jiang Chen nodded, put the drawings in the safe and locked it, and then said: "Okay, let's leave the drawings as they are. After communicating with Su Gong and the others tomorrow, we will determine whether they need to be modified."

Wan Li nodded: "Even if there is a problem, it is because there is a problem with Director Jiang's design concept. There is absolutely no problem with my drawing."

This guy has a brain like Einstein's when he's drawing, but other times his brain is weak.

After loading Liu Yue, the two chose to go home.

When Zhang Cui and Zhao Qi saw the two of them coming back, they put the fried food on the table.

Liu Yue said: "Mom, didn't you say I would cook?"

Jiang Chen likes the taste of her cooking, and she is also afraid that her mother will be tired, so she usually doesn't let Zhang Cui do it.

Zhang Cui smiled and said: "Qiqi cooked the food today. This child is good at studying and hard-working."

She still liked Zhao Qi very much, and she once thought that her daughter-in-law must be Zhao Qi.

Before coming to Sijiucheng, I received a letter from Jiang Chen saying that he already had a wife, so he scolded Jiang Chen in front of the security personnel.

It was only later that I met Liu Yue and found that this girl was also very good, so I gradually let go of my obsession.

I just felt a little indebted to Zhao Qi.

Then he couldn't bear to follow Jiang Chen's idea and drive Zhao Qi home.

It was just that she was praising Zhao Qi for her diligence, not her skills. Jiang Chen already had a bad feeling in his heart.

Zhao Qi said: "Come and try my craftsmanship."

Jiang Chen sat down and took a sip, frowning, this taste

It’s really hard to put into words.

Zhao Qi looked at Jiang Chen expectantly: "How is it?"

Jiang Chen sighed: "From now on, please stay away from our kitchen, otherwise I'm afraid I'll be poisoned to death by you one day."

Zhao Qin got a daughter in his later years and had a good family. This Zhao Qi really didn't want to get married, so it was really difficult for her to cook.

Even Luo Xue, who rarely does housework, is much better than her.

At least Luo Xue is self-aware and never asks for cooking.

Zhao Qi's high expectations instantly turned into full of disappointment: "Am I that bad?"

Then, he picked up a piece of vegetables and put it into his mouth, and spit it out immediately:

"Bah, bah, bah, too much salt."

Jiang Chen said: "That one has too much salt, and this one has no salt. If the two are mixed together to neutralize it, it should still be edible."

Zhao Qi's eyes lit up and he was eager to try: "Really?"

Jiang Chen said angrily: "What a fart, can you still eat these two dishes if they are mixed together?"

"Forget it, forget it, you've done everything, just eat it. Don't try to do it in the future. Just be good at the hall. Stop asking yourself to be good at the kitchen."

After saying that, he picked up the vegetables, ate the rice, and swallowed it down.

Zhao Qi pursed her lips: "Why don't you, Xiaoyue, cook a new dish? My dish is really..."

Liu Yue sat down with a smile: "We are all people who have lived a hard life, we don't have such high requirements, let's eat first!"

After saying that, he sat down and started eating without any disdain.

Zhang Huajun has not said a word from the beginning to now, just working outside the house.

Zhang Cui also picked up his rice bowl and started eating.

Seeing the family of three eating their food without any sign of disdain, something in Zhao Qi's heart was touched again.

It seems that it is quite good for four people to live together.

As for Zhang Huajun, he unfortunately became the object of her neglect.

While eating, Zhao Qi said: "Today I went to the Ministry of Industry and met the deputy minister. I thought I had a chance to find a job in the Ministry of Industry, but I didn't know that it didn't happen in the end."

"He said it would be fine if I majored in Russian, but majoring in English and other minor languages ​​is not needed by the Ministry of Industry."

Jiang Chen was stunned: "Deputy Minister, which deputy minister have you met?"

Zhao Qi said: "Vice Minister Lu."

Jiang Chen was stunned: "Lu Tianyi?"

Zhao Qi nodded: "It should be him. I don't know his name, but it's impossible for the Ministry of Industry to have two deputy ministers named Lu."

Jiang Chen said: "Hey, if you see Vice Minister Zhou, no chance will become a chance. If you see Lu Tianyi, then any chance will become no chance."

He can guess it all.

If it is not a very important position, how can a technical secondary school student who does not even have a letter of recommendation meet a minister-level person when he is looking for a job.

It must be because Zhao Qi and Jiang Chen are fellow villagers and the people below saw that his address was in the same place as Jiang Chen's, so she had the opportunity to meet Lu Tianyi.

It's just that now Chen Tongshan and Jiang Chen are competing for the development of alloy steel, and Lu Tianyi and Zhou Xinjian can't deal with each other. It's strange that Jiang Chen's fellow countryman can be allowed to enter the Ministry of Industry.

Zhao Qi was stunned: "You have a grudge against Vice Minister Lu?"

Jiang Chen shook his head: "It doesn't count as having a grudge, but it is certain that the relationship is not harmonious."

The entire Ministry of Industry regarded the Third Steel Factory as belonging to Zhou Xinyi's faction.

Moreover, Jiang Chen is still the sharpest sword in Zhou Xinjian's hand, so even if Lu Tianyi doesn't dare to do anything to Jiang Chen, he is definitely displeased with him.

Zhao Qi was stunned: "I failed to enter the Ministry of Industry because of you?"

"You have a good relationship with Vice Minister Zhou. Why didn't you tell me earlier so that I wouldn't hit a wall?"

Zhang Cui helped: "Even if you don't say anything to help Qiqi, she has been running outside all day today, how tired she is."

Jiang Chen snorted: "You will be admitted to the Ministry of Industry based on your own abilities and abilities. If you are not capable enough, you cannot blame the problem on me."

Zhao Qi snorted: "Why are you so old-fashioned in your thinking? If nothing else, we are at least fellow villagers. What's wrong with saying something to the fellow villagers?"

"Besides, that's not what you do in the factory. So Luo Xue, Bai Jingdaifang, even if there is nothing between you, you did your best to help them transfer positions. Why do you think it's all about your ability when you get to me? "

Jiang Chen waved his hand: "Can we not mention this matter? The rumor maker was caught yesterday, which proved my innocence. This matter has been over."

Zhao Qi snorted: "It's faster to let go of the relationship, man. Humph!"

Seeing the two people facing each other, he changed the topic and said, "The sister-in-law of the Jia family across the door is really cruel. Just because her daughter-in-law gave birth to a daughter, she now takes her grandson with her all day long and doesn't care about anything else. "

"Qin Huairu has only been born for a few days, and she has to work in the fields, cook and serve her. I just saw her washing clothes."

"The little girl who was just born is also very fussy. She cries during the day and at night. Once she starts crying, she won't stop crying."

Jiang Chen said: "That's what that person is like. Whenever something doesn't go according to her will, she has to kick her nose in and show off her face to others."

Zhao Qi asked: "Third Aunt, do you only like boys?"

Zhang Cui smiled and shook his head: "For me, a boy is the best. After all, the inheritance of the Jiang family cannot be broken. But girls can also accept it. They are not all of our Jiang family's blood. I will be very happy as long as I have a baby." La!"

"Besides, maybe if a daughter is born, it means that the sixth generation will end with Xiaochen. This is a great good thing."

Liu Yue lowered her head in discomfort.

Because it had been so long, there was no movement in her stomach, and her relatives still arrived on time.

This has something to do with the genes of the Jiang Chen family. It is definitely not a coincidence that the six generations have been passed down alone.

It also has something to do with her own endurance. She often can't hold on even before the last moment, which ultimately results in her hard work yielding no results.

She began to wonder how she could better cooperate with Luo Xue and increase her chances.
