Chapter 170 Researching New Materials
Back in the dormitory, Chen Zhihe and Fang Jiaming were there.
"Everyone has run away? You two are the only ones looking after the house."
"We have all gone to the playground to learn how to play ball. Quickly open your bags and see if you can bring something delicious for everyone. I seem to smell the fragrance."
In just a few days, Chen Zhihe and Fang Jiaming have become very familiar with Zhu Xuefeng, and they are not welcome at this time.
“Look at how greedy you are, why don’t you wait for them? Besides, didn’t you say that the food in the canteen is better than the food at home.”
“Now I know that eating more will make your stomach better. The more motivated you are, the faster you’ll get hungry.”
“Haha, you can make it up.”
Zhu Xuefeng didn’t prepare anything, so he just brought a bottle each of chili sauce and mushroom sauce. Let everyone prepare the meal, and then some snacks bought in the afternoon. I secretly roasted a few sweet potatoes and hid them. It is not appropriate to bring the others.
"Let's save the snacks for everyone to eat together. This sauce is so delicious. Why am I hungry again..."
"Between comforting my stomach and waiting for them, I obviously sided with my stomach. I decided to taste the sauce now."
Fang Jiaming took out his chopsticks and dipped some in the sauce. After tasting the chili sauce, I couldn't help but stick out my tongue.
"It's too spicy. Do you northerners eat it so spicy? Oh, oh, oh, I can't stand it. I can't stand it."
Looking at Fang Jiaming's embarrassment, the two couldn't help but laughed.
"Come on, come on, use this to relieve yourself."
Zhu Xuefeng simply took out the roasted sweet potatoes and threw one in each person. He originally planned to satisfy everyone, but now it became an emergency.
“Try it, it’s just roasted, it should still be warm.”
“Wow, good stuff, it tastes best only when it’s roasted. I’m afraid of eating it any other way.”
The two of them didn't care about the image. As expected, it was still warm. The outside of the skin was still a little sticky, and the sugar was baked out.
“What are you eating secretly? It’s so delicious, sweet potatoes, right?”
The door was pushed open immediately, and a few people who had been sweating on the court came back. Except for Zhou Jidong, who was reserved for a while, the others were about to get started.
Zhu Xuefeng quickly took out the bag and took out the sweet potatoes.
"Boss, don't grab it, everyone has it, yours is here...".
"Lao Wu, close the door. The one next door came back with us. What if...".
Before he finished speaking, several people came in from the door, smelling the aroma of roasted sweet potatoes, and came in sweating profusely.
"You are eating alone in your dormitory. Take it out and share it with the revolutionary comrades."
As long as someone takes the lead, you can imagine that metal physics is like a monk class. This will make everyone The boys in the class quickly got into a group.
We usually don't tell each other apart, and we will definitely not be polite when we have something to eat. We call it euphemistically and enter GCism in advance.
Zhu Xuefeng shook his head and could only watch from the side. More than a dozen large animals were squeezed into the small dormitory. They probably had to eat all the sweet potatoes even with their skins.
Usually they look gentle and gentle, but now that I know them, they all look like bandits.
It took a while for it to quiet down. Everyone looked at the messy table and laughed, scrambling to eat everything.
"I obviously eat better than at home, but why do I always feel hungry..."
"Me too...".
"Thanks, come back next time, haha" Finally left, Fang Jiaming took out snacks and sauce from under the table.
“Fortunately, I have sharp eyesight and quick hands, otherwise the real treasure would definitely suffer.”
“I said it was gone in the blink of an eye, but you still have quick hands, old man, hurry up Put it away and take it out for dinner tomorrow.”
…
After finishing it, everyone went to study separately. The dormitory seemed very quiet, and Zhu Xuefeng was also studying hard. The students study very hard. Except for necessary exercises and activities, they spend all their time racing against time.
We are in the construction period of another five-year plan. Although it is still very difficult, we can all feel that the entire country is booming and prosperous. The country calls on young people to march into science, and everyone is full of expectations for the future. and vision, all want to contribute to development.
According to everyone, with such good learning conditions, if I don’t study hard, I won’t be able to afford daily food.
In this environment, you can't even think about not studying. This is one of the reasons why Zhu Xuefeng runs out every night.
…
I took a morning class, which was all about the People's Education Press version of "General Physics". This course has many branches, including molecular physics, thermodynamics, optics, electromagnetism, etc. part.
The molecular physics class in the morning gave Zhu Xuefeng some inspiration and brought back some memories, so he hurriedly came to the library to look up information.
The ductile iron technology was indeed found. This technology, which has been vigorously developed decades later, indeed has information now. Zhu Xuefeng borrowed several books at once, and he had to study these carefully.
The information is very clear. Due to its excellent properties of high tensile strength and good toughness, ductile iron entered large-scale industrial production in developed countries in 1948.
What surprised Zhu Xuefeng was that ductile iron was successfully developed in China in 1950, but it was not very mature. It used a pressure plus magnesium spheroidization method to treat ductile iron with pure magnesium. Just in 1958, it was Rare earth magnesium ductile iron was developed.
In fact, the level of national scientific and technological research during this period was not far behind the world. The research on many projects was still at the forefront of the world, especially the research on some new technologies, even ahead of the United States and Maozi. It's just that future generations don't know it clearly.
The research on ductile iron should have started very early, but it has not yet been industrialized, let alone ductile iron products. In the final analysis, it is still technically immature.
This technology has been widely used in later generations, including trains, cars, tunnels, bridges, sewer pipes, telephone poles, etc. There are countless.
The current development of high-power engines is not going smoothly, and materials are also an important constraint. The broken axles of heavy-duty trucks are all due to material reasons.
Zhu Xuefeng has long wanted to change the material of the engine. Unfortunately, aluminum alloy seems to be difficult at present. One is the restriction of casting technology, and the other is the shortage of materials. These are not problems for ductile iron.
The cast iron engines commonly used in later generations contain silicon, carbon, manganese, sulfur, and phosphorus. Although I don’t remember the specific proportion, due to work reasons, I know it is within a few thousandths to five percent. This Once you have a clear direction, just keep experimenting, which is better than others groping blindly.
I am currently studying metal physics. It makes sense to do research and experiments in this area. There is also the Materials Research Institute of the steel rolling mill, which should also be able to provide some help.
Having found a short-term breakthrough, Zhu Xuefeng was very excited. The metal physics in the Department of Physics really came to the right place by accident.
During this period, Zhu Xuefeng, in addition to going back to the courtyard to practice martial arts at night, and sometimes going to the laboratory to do some research, spent all his energy on the research of ductile iron technology, forgetting to eat and sleep like his classmates.
During the period, I went to the steel rolling mill and talked with the factory director and deputy director Jiang about the international application of ductile iron technology and the current domestic situation.
Secretary Chen was thoughtful and took a while before speaking.
"I have an impression of what you are talking about. The substitution of iron for steel that was strongly advocated in the past few years should be the case, but it has not been implemented."
"The technology is not yet mature. The United States and Europe have used it. The annual output of ductile iron has exceeded 100,000 tons. We still don't have a kilogram."
Zhu Xuefeng also introduced the development prospects, This must be deceived. Without the support of the steel rolling mill, Zhu Xuefeng alone has no hope. It is not a one-person thing at all. It must be the strong support of the team and the back.
Everyone was silent for a long time, and the smoke had filled the whole room. It seemed that the leader was also under great ideological pressure.
"Then the car you mentioned..."
Director Yang still couldn't forget Zhu Xuefeng's original idea. What would happen to the car behind this if he went to study the materials.
