"Headquarters is preparing to experiment with seamless lines. I know you have a lively mind and a lot of ideas. Please take the initiative this time and sort out all your ideas and give them to me.
If you do this well, you can take whatever tea you have here. "
Yan Jiecheng laughed and said, "I'm not polite, Mr. Luo. I will definitely clear the place for you."
Yan Jiecheng was thinking about the seamless line.
Literally, it means a line without seams. To put it more professionally, it is a line where standard length rails are welded or glued into long rails.
Generally, railway lines are connected by rails one by one. When people sitting on the train pass the rail joints, they will make a clanging sound.
This seamless line has a very core problem, which is the problem of thermal expansion and contraction.
If not handled well, it will break in winter and rise in summer.
Yan Jiecheng has a big problem. There are only so many problems. From transportation to welding, they are all difficult for today's country.
Only then did he realize that he had been fooled by the old man again and said, "Oh, your tea doesn't taste good either."
"Haha, what do you think?"
Luo Gong took a sip of tea and looked at Yan Jiecheng and said, "I heard that you, kid, often go to the Jiaotong University's library recently, and the library is bustling every day."
"Hey, look at what you said, how can you say that borrowing books is a big deal?" Yan Jiecheng said unhappily.
Luo Gong looked at him with a smile and said, "How did I hear that the Jiaotong University Library won't let you in now? It's like guarding against thieves."
Yan Jiecheng said with a look of disdain: "Hey, for such a big university, it is too ungrateful to be a scholar.
I just took a few books from them and talked about them everywhere. "
"How many books do you have? I have a collection of more than 400 books. Have you read them all?"
Yan Jie was a little embarrassed when he saw that Luo Gong had exposed him.
It turns out that after Yan Jiecheng moved to the college to work, he went to Jiaotong University to borrow books when he had time.
But with his abnormal memory, he could only read a book in two days at most.
So I simply borrowed a few more books every time, but later I found out that their college didn’t have a library.
Yan Jiecheng suddenly thought and borrowed more than 400 books from Jiaotong University.
Jiaotong University also enthusiastically asked students to help move books.
When the book arrived in Yan Jiecheng's hands, he found an empty house in the Technical College and built a small library.
Yan Jiecheng also went to Dean Yan, and after a while of discussion, the two laughed horribly.
Subsequently, he sent an official letter to Jiaotong University, highly praising Jiaotong University for its selfless and enthusiastic spirit of helping.
He said that the technical college received the books donated by Jiaotong University, and the teachers and students of the school were very happy and everyone was very grateful.
Seeing Luo Gong's look of contempt, Yan Jiecheng suddenly became a little more confident.
Said: "It's not like we didn't thank them. Our college also issued them receipts and wrote letters of thanks."
"Hey, Luo Gong, I'm not talking about you, we are a family.
Why do you always speak for outsiders? "
Luo Gong looked at Yan Jiecheng's face carefully and said expressionlessly: "I have been the president of Jiaotong University for ten years, and my family is there."
Then he said: "I asked Jiaotong University to make a sign and put it at the entrance of the library, saying that Yan Jiecheng is not allowed to enter."
Yan Jiecheng opened his mouth and said: "Mr. Luo, this situation is too small. We, a great university, cannot be like those Japanese devils and do something so childish that Yan Jiecheng and dogs are not allowed in."
"Well, this is good. I'll ask them to change it later."
Yan Jiecheng:...
"You, stay away from Huohuo and the others recently. I heard that they are looking for you recently. Don't let them catch you and treat you like a donkey."
Yan Jiecheng smiled, how could it be possible?
Ever since he copied other people's books, he never went to Jiaotong University again.
At this point, he was still a little worried.
It is said that this matter has been brought to Minister Teng.
According to Dean Yan, Minister Teng seriously criticized Yan Jiecheng's gangster behavior in front of Principal Mao.
After Principal Mao left, Minister Teng said to the people around him: This young man is good, don't wait until you can rely on him. It is very traditional for us to make things by ourselves and have enough food and clothing.
After chatting with Luo Gong for a while, seeing that it was getting late, Yan Jiecheng said goodbye and left.
The next day, Yan Jiecheng asked about the seamless line at school, but no one knew about it.
In the eyes of Lao Xie and others, the rails are just connected one by one. They have been used well, so why do they need to be welded together?
Seeing this, Yan Jiecheng also knew that not many people in China knew about seamless lines, and it seemed that he would have to put a lot of effort into this task.
Call Chen Hanliang and ask him to assist. After all, he is a top student at Jiaotong University, so he can still do some tricks.
"Han Liang, I have an important project here and I need your help to complete it." Yan Jiecheng said warmly as he poured a glass of water for the young man.
When Chen Hanliang saw this, he was surprised. What important issues could their technical school have?
Yan Jiecheng knew what he was thinking by looking at his face, and explained: "This topic was assigned by Member Luo of the academic department.
It is a key issue of railway transportation in our country.
It’s the research and implementation of seamless lines I mentioned earlier. "
Seeing this, Chen Hanliang said: "Director, but, but I don't understand this at all. This is the first time I have heard of it."
Yan Jiecheng smiled and said: "It's okay, Han Liang, I understand.
Your task is to contact the rolling mill and ask them about the expansion coefficient of the rails.
Just calculate it, if we use one kilometer as the unit.
At what temperature is it laid, its shrinkage is the same as its elongation. "
“The other thing is to calculate the expansion and contraction of the rail as the temperature changes.
And the changes in temperature stress inside the rail. "
Chen Hanliang felt that Yan Jiecheng was important, and then he vaguely agreed.
Yan Jiecheng thought that the workload was not small and it would have to rely on the efforts of everyone in the department.
Then he said to Chen Hanliang: "Hanliang, tell everyone.
Let me just say that everyone should not leave after get off work today. I will tell you about the seamless line. As professionals, we still need to understand it.
It can be regarded as a professional and technical lecture given to them by me, the director. "
Wait for Chen Hanliang to leave.
Yan Jiecheng took out his pen and started writing in his notebook.
After all, I will be giving lectures to everyone soon, and they are all professionals. You still need to be prepared, otherwise it will be bad if you make a joke.
He thought for a while and wrote a few titles.
Advantages and Disadvantages of Seamless Lines.
Classification of seamless lines.
Construction of seamless lines.
Stress relief for seamless lines.
Seamless line maintenance.
Everyone in the office heard Chen Hanliang's words. There were heated discussions.
After all, their college has only been established for a short period of time and has not yet held any technical lectures.
Yan Jiecheng also held the first regular meeting in the hospital.
Even Dean Yan heard about this and said that he would also participate.
