Chapter 423: Ilmenite Slag is a Treasure
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 said nothing, waiting to see Qin Hai's reaction.
Qin Hai picked up the first thing, only to see that it was a piece of glass with an irregular shape, and when he looked closely, 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 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 that Su Changliang had placed in front of him. It is a stone with an extremely rough surface and numerous holes in it. Ning Mo glanced at the side and said in surprise: "Isn't this just a piece of slag?" There's a whole hill behind our steel mill that's it. ā
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 the slag and asked Su Changliang: "Section Chief Su, where did this slag come from and what are the main ingredients?" ā
Su Changliang said: "When you arrive in our Hanping County, you should have heard that there used to be a steel factory in Hanping, but now it is closed. This slag was picked up by me from a mountain of slag from a steel mill. I've tested its ingredients, mainly titanium dioxide. ā
"It turned out to be a piece of ilmenite slag." Qin Hai nodded, then put down the slag, picked up the glass again, and said, "If I'm not mistaken, this glass is slag glass-ceramic produced from ilmenite slag as a raw material." ā
"Qin Gong is really good eyesight!" Su Changliang sighed heartily, "I know that only Qin Gong can understand this thing." ā
The so-called glass-ceramic refers to a composite material in which the microcrystals and glass are evenly distributed after the heat treatment of the glass of a specific composition at a certain temperature, which is also a kind of glass in a broad sense. Glass-ceramic can be used as an alternative to ceramic materials and natural stone. It has the characteristics of soft texture, non-absorbent, high strength, acid and alkali resistance, etc., and belongs to a high-grade decoration material. In addition, glass-ceramic is also widely used in daily necessities, electronics, optical instruments and other fields.
The production process of glass-ceramic is not much different from that of ordinary glass, mainly in the preparation of raw materials and the processing of finished products. By transforming the technology of an ordinary glass factory, it was possible to switch to glass-ceramic. The price of glass-ceramic 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 rejecting the idea of increasing the production scale of the Hanping Glass Factory, Qin Hai was wondering whether he could make the factory switch to glass-ceramic. The reason why he didn't tell Ning Mo about this plan was because he was still unsure about two things, one was whether he could find raw materials for the production of glass-ceramic in Hanping County, and the other was whether the Hanping Glass Factory had personnel who understood the glass-ceramic production process. He invited Su Changliang over to verify these two problems with Su Changliang, but he didn't expect Su Changliang to see the same thing as his hero, not only did he think of glass-ceramic. Even samples have been developed.
"Section Chief Su, tell me how your glass-ceramic is produced. Also, how did you come up with the idea to study glass-ceramic? Qin Hai asked with interest.
Su Changliang said: "It's a long story to talk about. I also accidentally noticed the glass-ceramic when I was looking at professional materials. Some domestic enterprises try to use slag as a crystal nucleating agent and co-solvent to produce slag glass-ceramic with waste glass. I saw that our steel mill also had a pile of slag, and I thought about it. I got some slag and started it in the real yĆ n room of our factory. The work paid off, and it really allowed me to make such a few pieces of glass. ā
Qin Haidao: "This is also a coincidence. Titanium dioxide is indeed a crystal nucleating agent and co-solvent with excellent properties, and together with the matrix glass of the sodium oxide-alumina-silica series, it can produce glass-ceramic with low expansion, high insulation and high wear resistance. Section 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-ceramic. ā
"Absolutely." Su Changliang said, "The iron ore in our Hanping is ilmenite. The steel mill has been producing for decades, leaving at least tens of thousands of tons of slag behind. If we were to produce glass-ceramic at a scale of 30,000 weight boxes per year, the slag would be enough for decades. ā
"Since that's the case, did you mention this plan to the factory before we came?" Qin Hai asked again.
Su Changliang sighed. Said: "I told our director Pang about this matter, and I also showed him the glass samples." However, there are still many obstacles to switching to glass-ceramic, and Director Pang is unwilling to take this risk, and the county can't afford to come up with so much money. ā
"Do you think we can afford to take the risk?" Qin Hai deliberately teased Su Changliang.
Su Changliang's face changed slightly, and he said, "I am also a dead horse and a live 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 could see at a glance that this was a piece of glass-ceramic, and this alone proved that Qin Gong understood the technology of glass-ceramic. To be honest, there aren't even a few people in our factory who have heard of the word glass-ceramic. If I hadn't seen Qin Gong, I wouldn't have taken out this piece of glass and replaced it with a layman, I would have made a secret investment in the pearl. ā
Qin Hai looked at the glass in his hand again and said, "Section Chief Su, with all due respect. Although you have produced this glass-ceramic in the real room, I am afraid that it has not been tested for its strength, whether the coefficient of thermal expansion can meet the requirements, and what the surface density is, right? As a real product, it is barely qualified, but there is still a long way to go before it can be put into commercial production. ā
Su Changliang nodded desperately and said, "I know, I know." In order to make qualified glass-ceramic, we need to do a lot of real glass, and we also need to do electron microscope testing, which our factory does not have. I proposed to our factory director to allocate some funds to do this, but he firmly disagreed, so the matter was shelved. ā
"If our group pays money, please do follow-up research, but the patent researched belongs to our group, and the production can be handed over to Hanping Glass Factory to complete, are you willing?" Qin Hai asked tentatively.
Su Changliang hesitated for a second, then nodded solemnly and said, "I'm this age, what more patents do I need?" If we can save our factory, my family's livelihood will be guaranteed, and I am willing to do this. ā
"If Section Chief Su can have such an idea, this matter is half the success. For the other half, we still have to ask the group again, after all, if we want to change the products of Hanping Glass Factory to glass-ceramic, the investment required is very large, and Ning Mo and I can't make decisions 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 more than 20 million will be invested in order to change our existing production process to glass-ceramic process, such a large investment, we would not dare to think of in the past." ā
Speaking of this, Su Changliang didn't have anything more to say, he ate for a while, and then got up to say goodbye. Qin Hai didn't keep him, but just asked Heizi to call a taxi again and send Su Changliang back to the glass factory.
Seeing Su Changliang leaving, Ning Mo eagerly asked Qin Hai, "Qin Hai, is what you just said to Lao Su true?" ā
"Of course it's true." Qin Hai replied angrily, "Old Su is a handful of years old, can I fool him?" ā
"What do you mean by glass-ceramic? Can it be produced in Hanping Glass Factory? Ning Mo continued to ask.
Qin Hai briefly introduced the concept of glass-ceramic to Ning Mo, and then said: "I just had such an idea, and after seeing the samples brought by Lao Su, I am basically sure now." The production of glass-ceramic requires nothing more than ordinary glass raw materials and raw materials as crystal nucleating agents. If the Hanping Iron and Steel Plant can provide tens of thousands of tons of ilmenite slag, the problem of crystal nuclide will be solved, and the rest will be the problem of production process and production equipment. As for the sales of glass-ceramic, there is no need to worry, this is a new material, and the market is very broad. ā
"That's great!" Ning Mo high-fived with his fist, so excited that he was about to jump up. Being able to help his quasi-father-in-law in a way that is beneficial to the group is, of course, the result that Ning Mo wants to see the most, otherwise even if he is willing to come up with the money, he will have a feeling of being unjustified and unspeakable, and when his little Qiqi asks in the future, he will not be able to answer.
Qin Hai looked at Ning Mo's expression, feeling angry and funny, he couldn't imagine that Ning Mo, who had always been very aggressive, also fell in love and couldn't extricate himself, and like countless nymphomaniac youths, Ning Mo's IQ had dropped to the kindergarten level, which was completely unreasonable. However, the fact that his buddies can find happiness is also something that Qin Hai is happy to see, so he is willing to spend some energy to promote this matter.
While speaking, Heizi had already returned, Qin Hai asked Heizi to sit down, and explained to him: "Heizi, you also heard what I talked about with Lao Su just now. If the glass-ceramic project is feasible, we will invest at least 20 million yuan in Hanping Glass Factory, and at least occupy eighty percent of the shares of Hanping Glass Factory. If the project is run properly, it will be able to recoup the entire investment in two or three years. So the biggest problem now is whether there is anyone in Hanping Glass Factory who can pick this beam. Do you understand what I mean? ā
Heizi nodded and said, "I understand, Mr. Qin, I will go to the glass factory tonight and thoroughly understand the situation of the whole factory." ā
"Be careful not to make a noise." Qin Hai admonished, and after that, he turned his head to Ning Mo and said, "Fatty, the matter over there in the glass factory, let Heizi understand, isn't your father-in-law going to have a treat tonight, let's go talk to him again." (To be continued......)
