Chapter 8 Electric Scum and Human Scum

The document in Gao Zhendong's hand was a printed draft of a PPT document with a string of large characters written on the cover: "Technical Principles and Latest Developments of Electroslag Remelting (ESR)". Although it was thin, it had about a hundred pages and was printed on both sides. Does the system also save paper?

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 hot capping, electroslag welding, electroslag composite, and electroslag tundish heating.

The basic and core technology is the electroslag remelting (ESR) in Gao Zhendong's hands. Its purpose is to further purify steel and alloys and improve the crystal structure of steel ingots on the basis of primary smelting, so as to obtain high-quality metal products.

The product itself can be cast or continuously cast by remelting cooling process to form castings or rough blanks, which can be used for further forging or rolling in a steel mill.

Electroslag remelting began industrial production in the Soviet Union and China in 1958, and in Western countries around 63.

Although this method has some disadvantages such as low production efficiency, high power consumption, fluorine pollution, low product cleanliness, easy oxidation of elements, high gas content, and serious solidification segregation of large ingots, it also has obvious advantages such as the remelted metal can be effectively refined by slag, the crystallization conditions of metal ingots can be improved, the yield rate of metal can be increased, the equipment is simple, the production cost is low, the operation is easy to master, the product variety is large, and the application range is wide.

With the continuous improvement of technology and processes, it is still the most widely used secondary refining method in the world, mainly used in the production of special steels and alloys.

Although the industrial production of ESR has started in China in 58, it is still in its infancy and there is not much related research.

More importantly, Gao Zhendong's materials not only explain the principles, but also the "latest developments" of ESR technology up to the 21st century. This is amazing. Although many things are just briefly mentioned, there are still some very detailed cases or practical technology introductions. It is no exaggeration to say that this material alone is enough for Gao Zhendong to eat for decades, provided that he really wants to switch to metallurgy.

Gao Zhendong didn't think so much. He still wanted to work harder on his major. However, 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 simple, and he could quickly produce results after thoroughly understanding some materials. As a graduate of automation, it was natural for him to take a small step into secondary refining production.

Moreover, even if it cannot be rolled out on a large scale due to investment issues, the results of this thing will not be wasted. ESR itself is suitable for small-scale production of special alloy materials. This type of material can be used as a highlight of the steel rolling mill. As long as the results are good, 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 my teacher, and read some books on metallurgy, and try to produce a result as soon as possible that is both distinctive and can be realized." Gao Zhendong thought to himself. However, this matter cannot be rushed in a short time, and he has confidence and patience.

After joining the work, Gao Zhendong planned to use the collective strength at the appropriate time to organize people to carry out related work, divide the work and the credit, and want to keep all the benefits in his own hands. Basically, nothing can be accomplished. Apart from anything else, the workload is not something that can be completed by one person.

Gao Zhendong spent this morning studying ESR technology over and over again. He just had a quick bite for lunch and then continued to read the materials.

Gao Zhendong kept watching until around three o'clock in the afternoon, when suddenly a loud commotion came from the middle courtyard where Sha Zhu and his family lived. The noise spread all the way from the middle courtyard to the front yard, and it was quite fierce.

Gao Zhendong put the materials into the storage room and walked out to watch the fun, just to rest his brain.
-
At noon, when Gao Zhendong was reading the materials, Sha Zhu was happily dressing himself up. An aunt introduced him to a distant relative and they were going to have a blind date. Sha Zhu was born in 1935 and was almost years old. His father had been dragged away to another province by a gang and abandoned him and his sister. In order to take care of his sister, Sha Zhu had never taken care of finding a partner. He had some potential, but it was ruined because of his sister.

Twenty-four years old is considered early marriage in the future, but now, it is definitely late marriage, and Shazhu himself is a little anxious. Auntie is kind-hearted, and she has watched Shazhu grow up since he was a child, and she doesn't have children of her own, so she pays more attention to Shazhu and arranges a partner for him.

At this time, the uncle's family should not have thought about Sha Zhu's retirement support. After all, the couple were not old enough to be completely hopeless, and their dear apprentice Jia Dongxu was still alive and kicking. In terms of closeness, it was not their turn to plot against Sha Zhu, not to mention that Jia Dongxu had a son and a daughter. If Jia Dongxu took care of the elderly, when Jia Dongxu was old and his son was grown up, wouldn't it be great if they could continue the relationship? The uncle could also calculate the account of losing watermelons to pick up sesame seeds.

By the time Shazhu put on a fake collar, a Zhongshan suit, and new white-edged cloth shoes made by the deaf old lady, and tidied his hair, when he was almost done, an old lady also led people to No. 95.

Along the way, the aunt introduced the situation to her distant niece as she walked.

"I've told your mother about this before, but I'm afraid that the message might be misspoken, so I'll tell you in detail so you can have a better idea."

"I have watched He Yuzhu grow up. He has a bit of a stubborn personality, but he is very quick-witted and has a lot of ideas when things happen. But he is a very nice person. He has a younger sister who is about to enter junior high school. She can manage her own affairs and does not need too much care."

"He supposedly has a father, but you just pretend he doesn't have one. I haven't heard from him for a long time."

"Silly Yuzhu works in the canteen of the steel mill as a regular worker, earning 37.5 yuan a month. Hey, why am I telling you this? He can brag about it eight times even if I don't tell you."

"Where were we talking just now? Oh, he's a cook at the steel mill. He and his family never starve. He's very kind to the elderly, and we can live together."

The girl who was with the old lady blushed a little. She kept her head down and listened to what the old lady said, occasionally responding with a low "hmm".

The two walked along and entered the front yard. At this time, Gao Zhendong was reading a book at his desk.

Just at the hanging flower gate in the front yard, the two men met a tall man with a horse face and a small mustache walking out. This man was none other than the number one scumbag in the courtyard, or even the only scumbag - Xu Damao.

There are many people in the courtyard who have problems, and many of them have serious problems. But in Gao Zhendong's opinion, others have problems for various reasons or are forced to do so. But the only one who is purely bad, has not forgotten his original intention, and remains the same as always, is Xu Damao.
