Chapter 8 Electroslag and Human Slag
The information in Gao Zhendong’s hand is a typed version of a PPT file, with a string of large words written on the cover: "Electroslag Remelting (ESR) Technical Principles and Latest Progress" 》, although it is thin, there are still more than a hundred pages, and it is printed on both sides. The system also saves paper. Is this so.
Electroslag metallurgy is a special smelting method that uses electric current to pass through liquid slag to generate resistance heat to heat and refine metals.
The development of electroslag technology has spawned many professional branches, forming a new cross-industry and cross-professional discipline, including electroslag remelting, electroslag casting, electroslag transfer, electroslag pouring, electroslag Centrifugal casting, electroslag thermal capping, electroslag welding, electroslag compounding, electroslag tundish heating, etc.
The basic and core technology is electroslag remelting (ESR) in the hands of Gao Zhendong. Its purpose is to further purify steel, alloys and improve the crystal structure of steel ingots based on primary refining, so as to obtain high-quality metal products.
The product itself can be cast or continuously cast using the remelting and cooling process to be cast into a casting or rough embryo. The rough embryo can be used for further forging or rolling in a rolling mill.
Electroslag remelting began industrial production in the Soviet Union and China in 1958, while Western countries began industrial production around 1963.
Although this method has shortcomings such as low production efficiency, high power consumption, fluorine pollution, low product cleanliness, easy oxidation of elements, high gas content, and serious solidification and segregation of large steel ingots. However, there are also remelted metals that can be effectively refined by slag, which can improve the crystallization conditions of metal ingots and increase the yield rate of metals. The equipment is simple, the production cost is low, the operation is easy to master, there are many product varieties, and the application range is wide.
With the continuous improvement of technology and processes, it will still be one of the most widely used secondary refining methods in the world in the future, mainly used in the production of special steel and alloys.
Although the industrial production of ESR has started in China in 1958, it has just started and there are not many related studies.
More importantly, in addition to the principle of transparency, the materials in Gao Zhendong's hands also have the "latest advances" in ESR technology as of the 21st century, which is amazing. Although many things are just mentioned, there are still some quite detailed cases or practical technical introductions. It is no exaggeration to say that this amount of material will be enough for Gao Zhendong for decades, provided that he really wants to switch to metallurgy. Professional words.
Gao Zhendong didn’t think so much. He still wanted to work more on his major, but this did not prevent him from using ESR as a stepping stone. What he valued most was that the equipment and principles of ESR were relatively good. It is simple and can produce results quickly after thoroughly understanding some of the materials. As a graduate of the automation major, it is natural for him to take a small step into secondary refining production.
And even if it cannot be rolled out in large quantities due to investment issues, the results of this thing cannot be wasted. ESR itself is suitable for small-scale production of special alloy materials. This type of material can be used as the highlight of the rolling mill. As long as the results are not problem, it is very easy to get support from the factory for small-scale production of special materials.
"Well, I have to go back to school and ask the teacher, get some books from the metallurgical major, and try to come up with a unique and tangible result as soon as possible." Gao Zhendong thought to himself, but this Things can't be rushed in a short time. He has confidence and patience.
After joining the work, Gao Zhendong plans to use the power of the collective at the right time to organize people to carry out relevant work, divide the work and the credit, and want to get all the benefits in his own hands. Basically It won't get done. If nothing else, the workload cannot be completed by one person.
This morning, Gao Zhendong spent his time repeatedly trying to learn ESR technology. During lunch and lunch, he dealt with two people casually, and then continued to read the materials.
Gao Zhendong just watched until three o'clock in the afternoon when suddenly there was a noise and noise from the middle courtyard where Sha Zhu and the others lived. There was a lot of noise and noise all the way from the middle yard to the front yard. They rushed over and made quite a fuss.
Gao Zhendong put the materials into the storage warehouse and went out to watch the excitement, thinking it was time to rest his head.
——
Just when Gao Zhendong was reading the materials at noon, Shazhu was happily telling himself that his aunt introduced him to a distant relative and was about to go on a blind date. Silly Zhu was born in 1935, and he is already two weeks old. He left the two siblings alone because of his father who helped him to go to other provinces. In order to take care of his younger sister, Silly Zhu has never cared about his partner. There were only a few hints of it, but it was because my sister was such a dragster.
Twenty-four years old will be considered an early marriage in the future, but now, it is a proper late marriage. Silly Zhu himself is also a little anxious. The eldest mother is a warm-hearted person, and she has watched Shazhu grow up since she was a child, and she doesn’t have any children, so she pays more attention to Shazhu and finds potential partners.
At this time, the first man’s family probably hasn’t thought about Shazhu’s support for the elderly. After all, the couple are not old enough to be completely desperate, not to mention that Qinqin’s apprentice Jia Dongxu is still alive and kicking. As far as close relatives are concerned, it is not the turn of the fool to plot, not to mention that Jia Dongxu has sons and daughters, Jia Dongxu takes care of him in old age, Jia Dongxu is old, and Jia Dongxu’s son is also old. Wouldn’t it be beautiful to continue the relationship~~~~Throw away the watermelon and pick up the sesame seeds. The boss can also calculate the account.
When Silly Zhu put on a fake collar, put on a Chinese tunic suit, and new white-edged cloth shoes made by the deaf old lady, and then straightened his hair until it was almost done, the aunt also led the people there. Number 95 is coming.
Along the way, the aunt introduced the situation to her distant niece.
"I told your mother before, but I'm afraid that there will be any mistakes if I convey the message in a hurry. If I tell you more carefully, you will have a clue in your mind."
"He Yuzhu is me. I grew up with a bit of a stubborn personality, but I am very quick-witted and have a lot of ideas when things happen. However, I have a little sister who is about to enter junior high school, and it doesn’t take much to be able to handle things on her own. Take care of me."
"Supposedly there is still a father, but I just pretend that he doesn't have one. I haven't believed him for a long time."
"Si Yuzhu is officially working in the canteen of the steel rolling mill. , a monthly salary of thirty-seven and five yuan. Hey, let me tell you what this is for. He would brag about it to you eight times even if I didn’t tell you.”
“Where did you say that? By the way, he is a cook in a steel rolling mill. He and his family are not hungry no matter what. He is very kind to the elderly and can live together. "
The girl who was with the eldest mother had a little red face. She kept lowering her head and listened to the eldest mother's words, and responded with a low "hmm" from time to time.
The two walked together and entered the front yard. At this time, Gao Zhendong was reading at his desk.
Just at the hanging flower gate in the front yard, the two of them met a tall man with a horse face and a mustache walking out. This man was none other than the biggest scumbag in the courtyard. It could even be said that he was the most scumbag in the courtyard. The only scumbag is Xu Damao.
To be said, there are many people in the courtyard who have problems, and there are quite a few problems that are quite big. But in Gao Zhendong’s feeling, other people have problems for some reason or as a last resort, but The only one who is pure in badness, never forgets his original intention, and remains the same as always, is Xu Damao.
