Siheyuan: The Era of Struggle

Chapter 46 I won't do it, even if I'm beaten to death
The four-roll rolling mill is a national heavy equipment, especially the thick plate four-roll rolling mill, which is an important equipment for manufacturing tanks and ship armor.

Hans was the first country to produce medium and thick plate rolling mills. That was at the end of the last century, which means that the Qing Dynasty was still in existence, and Empress Dowager Cixi had not yet shouted "I want the foreigners to die!"

During World War II, various countries vigorously developed thick plate four-roller rolling mills, but Rabbit, until thirty years later, still had to rely on imports for four-roller thick plate rolling mills above 5000mm.

When Yang Ning shouted out four-roller rolling mill, Professor Dong subconsciously thought it was a thick plate rolling mill, so he looked at Yang Ning as if he was a fool.

"Of course I know that a four-roller rolling mill is good, but with our current industrial manufacturing capabilities and material technology level, do you think we can make that thing?"

"Let's not talk about anything else. Let's talk about the working rolls and support shafts of the four-roller rolling mill. Where do we get them? We simply can't produce materials that meet the requirements."

Yang Ning saw that Professor Dong seemed angry, so he quickly stepped forward to explain: "Professor Dong, calm down, don't I know that thick plate rolling mills are difficult to build?

I was thinking about whether we could first design a short-stress cold rolling mill for thin plates, such as that used for rolling tinplate. This type of rolling mill does not have high requirements for the working rolls, and we should be able to produce it ourselves.

In this way, we can accumulate some experience in this area and also meet domestic needs, right?"

"Why would I design that thing? Not only would it be laborious, but it wouldn't contribute much to national defense. I don't have the time for that."

When Professor Dong heard what it was, he refused with a look of disgust.

After all, thick plate rolling mills can be used in the manufacture of ships, tanks and submarines, but those things have too high requirements for materials.

Although the thin plate rolling mill has lower material requirements, it is not very useful and can only be used to produce cans and some simple things. Isn't this a pure waste of resources?
No, I definitely won’t do it!
Now all the scientific researchers are gearing up to do something big. If he designs something like this at this time, it would be really embarrassing.

If they meet each other, one will say that what he designed is used in airplanes, and another will say that what he designed is used to produce guns.

What do you want Professor Dong to say? Will he say, "The things I designed are used in the production of cans?" That would make people laugh to death.

"No!" Yang Ning was not going to give up. After all, what Professor Dong designed was a two-roller cold-rolling mill. With a little improvement, a four-roller thin plate cold rolling mill would be ready. After all, they were all cold-rolled, and people's requirements were not high during this period, so the roll molds were universal.

"It's just a few more things. Please bear with it."

"Is this a matter of a few more strokes?" Professor Dong saw Yang Ning said it so lightly, raised his eyelids and glanced at him: "The balance structure of the four-roller rolling mill and the two-roller rolling mill is different, not to mention other things..."

At this point he seemed to have thought of something, he looked up at Yang Ning and asked: "By the way, I remember that your graduation thesis hasn't been finalized yet, right? Since you want to build this thing so much, then use this as your graduation project. Like you said, with these drawings of mine as a reference, it shouldn't be difficult, right?"

After saying that, he gloated at Yang Ning and thought smugly in his heart: "Hey, you kid want to embarrass me, then come and try it yourself."

"No..." Yang Ning looked at Professor Dong in surprise. Is that what I meant? I just exaggerated a little. Do you have to embarrass me like this?

Maybe this is not difficult for Professor Dong, but it is a bit difficult for Yang Ning.

But Professor Dong's face turned serious and he scolded, "What do you mean by not? Stop nitpicking. It's settled. If you have any questions, feel free to ask me."

Then Professor Dong took out two envelopes and handed them to him: "These are your things. One is a thank-you letter from the 320 Factory, and the other is a reward from the Second Ministry of Machine Building."

After saying this, Professor Dong picked up the teacup and signaled that it was time for him to leave.

But Yang Ning took the envelope without even looking at it and put it directly into his pocket, but he didn't leave.

"Why, you still want to eat with me? Let me tell you, I can't afford you. You can spend a day's salary on one meal."

"No, I just want to ask about my joining the organization. What are the rules?" Yang Ning was almost laughed at by Professor Dong. Not only did he give him such a difficult project, but he was even reluctant to treat him to a meal.

"Really!" Of course, Yang Ning only dared to say this in his heart. "Did Dean Guo tell you?" Professor Dong also became serious when he heard about this.

"You have to hurry up on this matter. Don't be careless. Just write the application as soon as possible and give it to me. Don't worry about the rest."

Then he asked, still worried: "Do you know how to write an application?"

"I know. Dean Guo gave me a draft." Yang Ning nodded and said.

"Now that you know it, why don't you just write it? What are you wasting time on?"

"Oh!"

"Go home!" After saying goodbye to Professor Dong, Yang Ning sat back in the car and said to Chen Jingguo.

The leader had already informed Chen Jing about the situation at Yang Ning's home, so after hearing what Yang Ning said, Chen Jingguo immediately started the car and drove towards the newly purchased courtyard of Yang Ning's family.

After Yang Ning asked them to park in a deserted place nearby, he sent Chen Jingguo and Hu Yinghong away and walked to the gate of the courtyard alone carrying his luggage.

"Mom, open the door!"

Yang Ning walked up and knocked on the door a few times, then shouted inside.

There was a crackling sound, and Yang Liu's voice came from the yard: "Is it the boss?"

"Mom, it's me!"

After Yang Liu opened the door and saw Yang Ning, she looked at him for a while to see if anything was missing.

"Hey, Mom, I'm back!" Yang Ning said with a simple smile as he looked at Yang Liu.

Seeing Yang Ning standing there intact, Yang Liushi breathed a sigh of relief, then looked at Yang Ning who was still standing there and said, "It's good that you're back. Are there any parts missing?"

"No, I'm fine." Yang Ning patted his chest and said.

"Okay, come in!" Yang Liu was about to take Yang Ning's luggage from behind, but was stopped by Yang Ning.

As soon as he entered the yard, Yang Ning saw the second monster, who had grown a lot, clinging to the door frame of the main room and looking at him, his big eyes full of curiosity.

"Second Monster, what's wrong? Don't you recognize your elder brother?"

Yang Ning put down his luggage, walked up quickly, picked up the two monsters, and asked with a smile.

"Big Brother?" The second monster was a little scared at first, but then he remembered something and smiled at Yang Ning: "Big Brother!"

"Hey, you still have a conscience. It's not in vain that I love you!"

Yang Ning put him back on the ground with a smile, then carried the luggage into the main room.
