Material Empire

Hearing Qin Hai's question, Su Changliang took out two things from the satchel he was carrying, put them in front of Qin Hai, and then kept silent, waiting to see Qin Hai's reaction.

Qin Hai picked up the first thing, and saw that it was a piece of glass with an irregular shape. After careful inspection, he could find that its surface luster was not the same as that of ordinary glass, but somewhat similar to the glaze layer on the surface of ceramics. Qin Hai lifted this piece of glass and looked at the sunlight, and found that its light transmission was also different from that of ordinary glass, and the light seen through this piece of glass was softer.

Qin Hai smiled slightly, put down the glass, and picked up the second thing Su Changliang put in front of him. This is a stone with an extremely rough surface, and there are countless holes in it. Ning Mo glanced aside and said in surprise, Isn't this just a piece of slag? The whole hill behind our steel plant is full of such things.

Of course Qin Hai recognized that this was a piece of slag left over from smelting steel, but it was difficult to see the composition of the slag for a while. He held up the slag and asked Su Changliang: Chief Su, where did this slag come from, and what are its main ingredients?

Su Changliang said: When you come to our Hanping County, you should have heard that there used to be a steel factory in Hanping, which is now closed. I picked this piece of slag from the waste slag mountain of the steel factory. Its composition, I Tested, mostly titanium dioxide.

It turned out to be a piece of ilmenite slag. Qin Hai nodded, then put down the slag, picked up the piece of glass again, and said, If I'm not wrong, this glass is produced from ilmenite slag as a raw material. slag glass-ceramics.

Qin Gong has really good eyesight! Su Changliang admired sincerely, I knew that only you, Qin Gong, could understand this.

The so-called glass-ceramic refers to a composite material in which microcrystals and glass are evenly distributed after heat treatment of a specific composition of glass at a certain temperature, and it is also a kind of glass in a broad sense. Glass-ceramic can be used as a substitute for ceramic materials and natural stone. It has the characteristics of soft texture, non-absorbent, high strength, and acid and alkali resistance. It is a high-end decoration material. In addition, glass-ceramic is also widely used in daily necessities, electronics, optical instruments and other fields.

The production process of glass-ceramics is not much different from ordinary glass, mainly in the preparation of raw materials and the processing of finished products. Through the technological transformation of ordinary glass factories, it is possible to switch to glass-ceramic production. The price of glass-ceramics is more than 10 times higher than that of ordinary glass, and it is a high value-added product. Therefore, the requirements for transportation conditions are not high, and it is suitable for production in places with inconvenient transportation such as Hanping.

After negating the idea of ​​increasing the production scale of Hanping Glass Factory, Qin Hai wondered whether the factory could switch to glass-ceramic production. The reason why he didn't mention this plan to Ning Mo was because he was not sure about two things. One was whether he could find raw materials for producing glass-ceramics in Hanping County, and the other was whether the Hanping Glass Factory knew about glass-ceramics. production process personnel. He invited Su Changliang here because he wanted to verify these two issues with Su Changliang, but he didn't expect that Su Changliang had the same idea as his hero, and not only thought of the product of glass-ceramic, but even developed a sample.

Chief Su, tell me how you produced this piece of glass-ceramic. Also, how did you think of studying glass-ceramic? Qin Hai asked with great interest.

Su Changliang said: It's a long story. I also inadvertently noticed glass-ceramics when I was looking at professional materials. Some domestic companies are trying to use slag as crystal nucleating agent and co-solvent, combined with waste glass Slag glass-ceramic was produced. I saw that our iron and steel plant also had a pile of slag, so I moved this idea, got some slag and started experiments in the laboratory of our factory. The hard work paid off, and it really made me create There are so many pieces of glass.

Qin Haidao: This is also a coincidence. Titanium dioxide is indeed a kind of crystal nucleating agent and cosolvent with excellent performance. When combined with the matrix glass of the sodium oxide-alumina-silica series, it can produce low expansion, high insulation and Glass-ceramics with high wear resistance. Chief Su, how much ilmenite slag does our Hanping Iron and Steel Plant have now, and can it support the demand for large-scale production of glass-ceramics?

It's absolutely possible. Su Changliang said, The iron ore in our Hanping is ilmenite. The steel plant has been producing it for decades, and the slag left behind is at least tens of thousands of tons. If we produce it on a scale of 30,000 weight boxes per year Glass-ceramic, these slags are enough for decades.

Since this is the case, did you mention this plan to the factory before we came? Qin Hai asked again.

Su Changliang sighed, and said: I have mentioned this matter to our factory manager Pang, and I have shown him the glass samples. However, there are still many obstacles in switching to glass-ceramics, and the factory manager Pang is not willing to bear the burden. For this risk, the county can’t afford so much money.”

Then do you think we can afford this risk? Qin Hai deliberately teased Su Changliang.

Su Changliang's complexion changed slightly, and he said, I am also a dead horse as a living horse doctor. Judging from what Qin Gong said to me this morning, I think Qin Gong is a person who understands glass. Just now, Qin Gong saw this at a glance. It is a piece of glass-ceramic. This alone proves that Qin Gong understands the technology of glass-ceramic. To be honest, there are not many people in our factory who have even heard of the word glass-ceramic. If it is not for seeing Qin I will not take out this piece of glass and replace it with a layman, I will count it as a hidden gem.

Qin Hai looked at the glass in his hand again, and said, Chief Su, with all due respect. Although you produced this piece of glass-ceramic in the laboratory, how about its strength, whether the thermal expansion coefficient can meet the requirements, whether the surface How about the density, I’m afraid it hasn’t been tested yet? As an experimental product, it is barely qualified, but there is still a long way to go before it can be put into commercial production.”

Su Changliang nodded his head desperately and said: I know, I know. To produce qualified glass-ceramics, a lot of experiments and electron microscope inspections are required. Our factory does not have these conditions. I told our factory manager He proposed to allocate some funds for this matter, but he firmly disagreed, so this matter was shelved.

If our group pays, please do follow-up research, but the patents obtained from the research belong to our group, and the production can be handed over to Hanping Glass Factory. Would you like it? Qin Hai asked tentatively.

Su Changliang hesitated for a second, then nodded solemnly, and said, I'm already old, what patent do I need? If we can save our factory, my family's livelihood will be guaranteed, and I am willing to do this.

If Section Chief Su can have such an idea, this matter is half successful. For the other half, we have to ask the group for instructions. After all, if we want to change the products of Hanping Glass Factory into glass-ceramics, the investment required It's a big deal, neither Ning Mo nor I can make a decision right away. Qin Hai explained with a smile.

Su Changliang said: I understand, I don't know much about the specific production process of glass-ceramic, but according to the information I have seen, it is estimated that at least 20 million yuan will be invested to change our existing production process to micro-crystalline glass. Glass technology, such a large investment, we never dared to think about in the past.

Speaking of this level, Su Changliang had nothing more to say. He ate for a while, then got up to leave. Qin Hai didn't keep him, but asked Heizi to call a car again to take Su Changliang back to the glass factory.

Seeing Su Changliang leave, Ning Mo asked Qin Hai eagerly, Qin Hai, is what you told old Su true just now?

Of course it's true. Qin Hai replied angrily, Old Su is already old, can I play him?

What's the matter with the glass-ceramics you mentioned? Can it be produced in Hanping Glass Factory? Ning Mo continued to ask.

Qin Hai briefly introduced the concept of glass-ceramics to Ning Mo, and then said: I just had this idea at first. After seeing the samples brought by Lao Su, I am basically sure now. The production of glass-ceramics, What is needed is nothing more than ordinary glass raw materials and raw materials used as crystal nucleating agents. If Hanping Iron and Steel Works can provide tens of thousands of tons of ilmenite slag, the problem of crystal nucleating agents will be solved, and the rest is the production process and There is a problem with the production equipment. As for the sales of glass-ceramics, there is no need to worry, this is a new material, and the market is very broad.”

That's great! Ning Mo clapped his fists and was so excited that he was about to jump up. Being able to help his prospective husband-in-law in a way that is beneficial to the group is of course what Ning Mo wants to see the most. Otherwise, even if he is willing to spend the money himself, he will feel a little unfair and inappropriate. When Xiao Qiqi asked, it was difficult for him to answer.

Looking at Ning Mo's expression, Qin Hai felt angry and funny. Unexpectedly, Ning Mo, who has always been carefree, also fell in love and couldn't extricate himself. Like countless young people who committed nympho, Ning Mo's IQ had dropped to the level of kindergarten. The level is completely unreasonable. However, Qin Hai is also happy to see that his buddies can find happiness, so he is willing to spend some energy to promote this matter.

During the conversation, Heizi had already returned. Qin Hai asked Heizi to sit down and explained to him: Heizi, you have heard what I talked about with Lao Su just now. If the glass-ceramic project is feasible, we must at least Hanping Glass Factory has invested more than 20 million yuan, at least 80% of the shares of Hanping Glass Factory. If this project is operated properly, the entire investment can be recovered in two or three years. The biggest problem now is that Hanping Glass Factory has No one else can take the lead. Do you know what I mean?

Heizi nodded and said, I understand, Mr. Qin, I'm going to the glass factory tonight to find out the situation of the whole factory thoroughly.

Be careful not to say anything. Qin Hai warned, and after finishing speaking, he turned his head to Ning Mo and said, Fatty, let Heizi find out about the matter at the glass factory. Isn't your father-in-law going to treat you tonight? Let's go again. Go talk to him.

Double monthly ticket period, the monthly ticket battle is fierce, do you have any idle monthly tickets?
