Chapter 440: Cryogenic material

Qin Hai felt a little guilty under the quiet persecution. He said negligently, "I don't mean that, I mean, if you really see it, you tell me the name."
"What?" Quietly didn't respond, and asked strangely.
Qin Haidao: "I cut the girl to death."
"You're swearing, you're swearing!" Tranquility turned to joy, but also embarrassed to show a happy mood directly, but could only grasp Qin Haifeng's swearing fault, and raised a fist to a storm. Qin Hai smiled and laughed, dodging, and there was a bright spring in the room.
"Uh ... I'll go to the school library to read a book." Qin Shan really couldn't stand it anymore. Although one was her brother and one was her girlfriend, but this kind of inappropriate scene for children, how could a big girl's house be able to Look at it calmly. She stood up and planned to pack her schoolbag.
"Okay, no problem. Xiaoshan, let's let Qin Hai take us to the movies? I haven't seen a movie in a long time." Quietly released Qin Hai, holding Qin Shan's arm.
"I can ..." Qin Shan just wanted to refuse, and her eyes suddenly turned, and she smiled, "Okay, brother, please invite me to watch a movie quietly."
"It's easy, let's go. Let's go to dinner first, and then go to the movies after dinner." Qin Hai agreed quickly.
Three people had a simple dinner at a restaurant not far from Huaqing University (meal. When they came out of the restaurant and were about to drive to Wudaokou Cinema not far away to watch a movie, Qin Shan suddenly seemed to remember something , Patted his head and said, "I'm going to die, I'm going to die. I remember that my sister and sister asked me to do an experiment tonight. How can I forget it ... brother, Xiao Jing. You two go to the movies, I Back to school. "
After all, she ran away without waiting for the two to have a taste.
Qin Hai looked at his sister's back, and muttered, "This is such a big person, and it's so sloppy. It's ..."
Speaking of this, he suddenly noticed that Tranquility was looking at himself with stubborn eyes. He froze for a moment, and then realized that what kind of fur grass was Qin Shan, clearly did not want to be a light bulb, and found an excuse to run away. After understanding this, he said to Serenity with an awkward smile, "Look, Qin Shan is gone. Otherwise, let's go to the movies together ..."
"Are you unhappy?" Serenity looked at Qin Hai with a smile.
"No, I'm very happy." Qin Hai said, "I was thinking just now, should I also care about Qin Shan's life, and quickly find her a boyfriend or something."
"Ha, you just remember now, your brother is too incompetent. Now I just want to care about my sister." Serenity said.
With a loyal face, Qin Hai said, "That's not what I meant. I mean, hurry up and marry her, so as not to be annoying ..."
"Qin Hai, you are so insidious!"
"Otherwise, let's find a way to get Ning Mo out, where to go ..."
"Who told you 'we'. Qin Hai, you are too narcissistic!"
"..."
That night, Qin Hai lived in a house rented by Tranquil and Qin Shan. Of course, he lived in Qin Shan's room. Qin Shan went to sleep in a room with Tranquility. In the early 1990s, Chinese society was not open enough, and Qin Hai did not dare to run the risk of being strangled by Ning Zhongying.
In the early morning of the next day, Qin Hai drove the car back to Beijing University and then took Qin Shan to the Chemical Design Institute. He made an appointment with Fan Zhiyuan of the Chemical Engineering Design Institute, and today he is going to discuss the design of ethylene equipment.
Ethylene is a basic chemical product, and many polymer materials require ethylene as a raw material. Qin Hai's breakthrough in the field of basic chemical engineering with ethylene as a breakthrough is a long established policy. As early as a year ago, he commissioned Huaqing University's Department of Chemical Engineering and the National Chemical Engineering Design Institute to jointly carry out the design of 800,000 tons of ethylene equipment. It has been a year now.
Before accepting Qin Hai's commission, the Chemical Engineering Design Institute had designed 300,000 tons of ethylene equipment and had certain experience, so the work of principle design progressed very smoothly. However, when it comes to the problem of equipment manufacturing technology, the Chemical Design Institute is a bit blind. The main obstacle is the low-temperature materials used in ethylene equipment.
Ethylene production involves many low-temperature links. The so-called "three ethylene machines" used in the production process, that is, ethylene compressors, propylene compressors, and cracking gas compressors all work under low temperature conditions, among which the inlet temperature of propylene compressors Generally it is minus 40 degrees Celsius, and the inlet temperature of the ethylene compressor reaches minus 102 degrees Celsius.
In low temperature conditions, the strength of many materials will be greatly reduced, so normal use of the equipment cannot be guaranteed. Therefore, to manufacture ethylene equipment, low-temperature materials are the most critical link. In a compressor, there are many different components, such as rotor impellers, spacers, shaft sleeves, screws, nuts, welding casings, and casting casings. Each component has different materials due to different working conditions. China has not been able to achieve 100% domestic production of ethylene three machines for a long time. The main reason is that some brands of low-temperature steel cannot be produced independently.
In response to this situation, Qin Hai resolutely invested 20 million yuan to help the Chemical Equipment Institute establish a low-temperature materials research center, and then made a special trip to Russia to hire experts such as Victor-Ceretelli to engage in low-temperature materials. Recently, Zhiyuan Fan, the director of the Research Center for Cryogenic Materials, called him and informed him that significant progress has been made in the research of cryogenic materials. He made a special trip today to learn about the specific situation.
As for her sister Qin Shan, Qin Hai has decided to arrange her as the group's supervisor at the Cryogenic Materials Research Center. In the future, Qin Hai will use this low-temperature materials research center and several other chemical laboratories as the core to set up a Daqin chemical engineering technology research company, and Qin Shan will be appointed as the chairman of this company.
During the period when Qin Hai was not in the capital, Qin Shan walked around these laboratories every three points, learned about the specific research situation, and reported to Qin Hai by phone. Although Qin Hai did not explicitly tell Fan Zhiyuan and others about arrangements for Qin Shan, everyone knows that Qin Shan is Qin Hai's sister and can guess the purpose of Qin Hai to arrange her to walk in the laboratory, so she will not reject her. Tour.
"Welcome welcome, Chairman Qin to the Chemical Design Institute for inspection."
At the entrance of the Design Institute, Fan Zhiyuan and several heads of the laboratory were waiting for Qin Hai and his party. When they saw Qin Hai's car stopped, everyone gathered around and greeted them warmly.
Qin Hai and Qin Shan got out of the car separately, Qin Hai shook hands with the crowd one by one, Qin Shan followed with Qin Hai, smiling behind Fan Zhiyuan and others. After greeting each other, Fan Zhiyuan asked: "Chairman Qin, shall we go directly to the research center, or go to our research room to sit first?"
Fan Zhiyuan's official identity is the director of the first research room of the Chemical Design Institute. Inviting Qin Hai to sit in the research room is a more official reception etiquette, and it is more casual to go directly to the research center. Qin Hai wasn't originally a fancy person, he waved his hand: "Director Fan, we don't have to be polite, just go to the research center."
"That's fine." Fan Zhiyuan responded. He explained to a subordinate that he went back to the research room to inform everyone to come to the research center for a meeting. He got in Qin Hai's car and took Qin Hai downstairs to the newly built research center. As for the other people who went to meet Qin Hai at the door, they arrived on their bikes.
Qin Hai, under the leadership of Fan Zhiyuan, had just entered the research center's building door, and met an acquaintance on the face, who was the Celjeli he had dug from the Soviet Union. Celjeli made a special trip to meet Qin Hai. When he saw Qin Hai, he opened his arms with a smile on his face. Qin Hai was not disgusted with this Russian etiquette. Haha hugged each other with a smile, and then asked in English:
"Mr. Celetelli, are you and your wife still used to living in China?"
"Thank you Mr. Qin, my wife and I are very accustomed in China." Zeljeli said with a smile, "especially my wife, except for some complaints about the hot summer weather, she thinks everything in China is very makes people happy."
"Is Mr. Rajimov in good health?" Qin Hai greeted Celetelli's father-in-law in the Soviet Union again.
Ceretelli said: "His health is also very good, and he intends to return to China for a while to check it out ~ EbookFREE.me ~ We are very welcome." Qin Hai said, he turned around and explained to Fan Zhiyuan around him Tao: "Director Fan, if Mr. Rajimov comes to China, all the reception costs will be borne by the research center, and he must provide the best treatment to the old man."
"Haha, please rest assured, we will take care of Mr. Rajimov." Fan Zhiyuan said.
Qin Hai did not ask Tseretelli about his son Xie Liaosha's situation, because Xie Liaosha is now working with Xie Qijin, in fact, he can be regarded as an outsider of the Daqin Group. Qin Hai knows his current situation very well. According to Xie Qijin, Xie Liaosha is now well-known in Chita and the surrounding states. Everyone knows that he is a client of a large Chinese company. Many technicians who think of going to gold in China are contacting him.
After talking a few other words, Qin Hai said, "Mr. Zheljeli, I am here today to learn about the research on low-temperature steel. Listen to Director Fan said that the research in this period is mainly led by you. Can you please give me a more detailed introduction? "
Ceregeli nodded and said, "Director Fan has explained to me yesterday. I would be happy to introduce to you our latest research progress. Please come with me." (To be continued ...) R12)
