The Grandmother in the Siheyuan

Chapter 186 Rat
The leader was amused. From a physics point of view, this statement is quite new, but it must be said that it is quite convincing and the angle is also unique.

The leader nodded: "It seems that I need to re-examine my opinion of Li Huaide."

After talking with his leader, Liu Hua was pulled over by the group of engineers again. They wanted to discuss technical issues and they were really busy all the time.

As the conversation went on, the topic was drawn to the issue of steel and iron making, because this is the basic issue of all heavy industries.

Steelmaking has made great progress, but there has been no breakthrough in ironmaking technology, so everyone was discussing the breakthrough points in ironmaking technology.

Liu Hua smiled and said, "Actually, I have an idea, but it cannot be realized for the time being. If it can be realized, the iron smelting process can be shortened to only one minute, or even a dozen seconds."

Liu Hua knew this from reading a paper in his previous life. At that time, some people in our country were researching this technology, but until Liu Hua came here, there had been no breakthroughs in the technology.

However, what Liu Hua didn't know was that not long after he came here, iron-making technology was broken through, and flash smelting technology was widely used in the smelting of non-ferrous metals. In 04, our country had flash smelting furnaces for smelting copper and nickel.

"Oh, what's the idea?"

Liu Hua's words quickly aroused everyone's curiosity. It must be such an advanced technology to be able to forge iron in less than a minute.

Liu Hua thought for a moment and said, "I read a book before, I can't remember what it was, I glanced at it occasionally and thought it was nonsense at the time, but after I got involved in this industry, I found that what it said made a lot of sense."

Someone asked curiously: "What does the book say?"

"It seems that in 1949, a Finnish company proposed the concept of flash refining technology."

Everyone urged: "Tell me more details."

"First, the ore is ground into fine powder, and then a special spray gun is used to spray the fine powder into the reactor. At the same time, a reducing agent is sprayed in. The high temperature and the reducing agent react instantly, reducing the iron element behind the iron ore to form iron vapor, which is then condensed and collected to form molten iron. The whole process is very fast, only a dozen seconds, or even a few seconds."

"It's a bit fanciful." Someone shook his head: "It should be feasible in theory, but it's not easy to form mature technology."

Another person retorted: "When any technology or concept is first proposed, it is basically a bit fanciful. As long as the theory is valid and efforts are made in this direction, it will become a reality sooner or later as technology advances."

Someone held up his chin and said, "There are many difficulties here. First, it needs to be ground into powder. What kind of powder should be ground into? Secondly, what is the spray speed of the special spray gun? What is the temperature of the furnace? What reducing agent should be used? Finally, how to collect it?"

Liu Hua smiled and said: "To sum up, there are only four difficulties, which don't seem to be that difficult."

Everyone laughed, and the person who summarized said, "These are just four major difficulties. Each difficulty needs to be subdivided. I don't know how many obstacles there are."

"It doesn't matter." Someone said confidently, "Let's work towards this goal. If one year doesn't work, then ten years. If ten years don't work, then twenty years. I believe that sooner or later we will achieve it."

Liu Hua finally said: "We will make a research plan and take this flash refining technology as our future breakthrough direction. I believe that with the development of time and the advancement of science and technology, all the problems here will be solved little by little. When the technology is reached, everything will come naturally."

"That's right. We can't be impatient. When it comes to technology, we can't just focus on speed. When it comes to basic materials, that's a lot of hard work."

That night, the leaders toasted Liu Hua, and Li Huaide blocked many of them for him, which made the leaders a little unhappy. These days, blocking toasts is also frowned upon. Only a real man can finish the toast. The next day when Liu Hua went to work, he found that the atmosphere in the factory was a little wrong. There were two more people guarding the door today, and Liu Hua found that he was not familiar with these people and had never stood at the door before.

When we arrived at the office building, we found that there were people standing downstairs, fully armed.

When Liu Hua was going upstairs, he met the secretary who was coming downstairs. He asked curiously, "What's going on today? I feel like the atmosphere is a bit heavy."

The secretary whispered, "We caught two people last night. They were trying to pry open the door of your technical department. They were caught red-handed. The relevant departments have sent people over. They are being interrogated in the security department now."

Liu Hua nodded: "No wonder, fortunately I put all the information in the security department yesterday."

"The factory manager got drunk last night. He got a call right after he got home and stayed here all night." The secretary whispered, "I heard that the outcome of the last incident will be resolved this time."

"That's good." Liu Hua nodded. "It's not a human job to be on guard against thieves for a thousand days. I'm always on edge. I still bring my stuff to work every day. My wife is extremely worried."

"Don't worry, Engineer Liu." The secretary comforted him, "It will be over soon. It's a mouse. He is doomed to lose to a cat. He dares to come to our steel mill to cause trouble. It's like lighting a lamp in the toilet. He is looking for death."

The commotion outside did not disturb Liu Hua's solid work. Everyone has their own expertise, and that was not his job, so he did not need to worry about it.

People nowadays are very bored. Any new thing around them will be enough for them to talk about for several days. After get off work that day, everyone in the courtyard holds their bowls and sits in the yard while eating and chatting.

"What's going on in the factory today? Everyone entering and leaving the factory has to be checked." Someone asked curiously, "Shazhu, you have a good relationship with the leader, don't you know what's going on?"

"How would I know?"

Xu Damao said mockingly: "That's right, he's just a stinky cook, what can he know? He only knows about potatoes, cabbages, and radishes."

Sha Zhu mocked back: "I don't know, do you know?"

Xu Damao said proudly: "Don't tell me, I really know it. This matter is not a secret in our office at all."

Several people came up to him and said, "Tell us, Damao, tell us about it in detail."

Xu Damao said, "Don't ask around, or you'll get into trouble."

"Tsk, you already said it's not a secret in the office, why are you keeping it a secret from us workshop workers?"

"Hua Zi." Someone saw Liu Hua coming back and came up to him and asked, "Why is the factory so busy today? Do you know what's going on?"

"I know." Liu Hua said with a smile, "I just caught a few rats that are not worth mentioning. Now I want to turn over the rat's nest."

All of a sudden, more people gathered around him, asking Liu Hua about it. Liu Hua said helplessly, "Everyone, I just got back. Can you let me go home to put my things down and have a drink of water first?"
