Upon hearing Qin Hai's question, Su Changliang took out two things from the bag he was carrying and placed them in front of Qin Hai. Then he remained silent and waited 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. Upon closer inspection, he could find that its surface gloss was not the same as that of ordinary glass, but rather similar to the glaze layer on the surface of ceramics. Qin Hai put the
Lifting this piece of glass and looking at it towards the sun, I found that its light transmittance is also different from ordinary glass. The light seen through this piece of glass appears softer.
Qin Hai smiled slightly, put down the glass, and picked up the second thing Su Changliang placed in front of him. It was a stone with an extremely rough surface and countless holes inside. Ning Mo glanced aside and said in surprise
: "Isn't this just a piece of slag? The entire hill behind our steel plant is covered with something like this."
Of course Qin Hai recognized that this was a piece of slag left by smelting steel, but it was difficult to see the composition of the slag at the moment. 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 arrived in our Hanping County, you should have heard that there used to be a steel factory in Hanping, but it has now closed. I picked this slag from the waste slag mountain of the steel factory. Its composition, I
It’s been tested and it’s mainly titanium dioxide.”
"It turns 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 guessed correctly, this piece of glass is produced using ilmenite slag as raw material.
of slag glass-ceramic.”
"Qin Gong has really good eyesight!" Su Changliang admired sincerely, "I knew that only you, Qin Gong, can understand this thing."
The so-called glass-ceramic refers to a composite material in which microcrystals and glass are evenly distributed after heat treatment of glass of a specific composition at a certain temperature. In a broad sense, it can also be regarded as a kind of glass. Crystallized glass can be used as a ceramic material, which is natural.
A substitute for stone. It has the characteristics of soft texture, non-absorbent, high strength, acid and alkali resistance, etc. It is a high-end decoration material. In addition, crystallized glass is also widely used in daily necessities, electronics, optical instruments and other fields.
.
The production process of glass-ceramics is not much different from that of ordinary glass. The main differences are in the preparation of raw materials and the processing of finished products. By carrying out technical transformation of ordinary glass factories, it is possible to switch to the production of glass-ceramics. Glass-ceramics
The price is more than 10 times higher than 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 like Hanping.
After rejecting the idea of increasing the production scale of Hanping Glass Factory, Qin Hai was wondering whether the factory could be converted to produce crystallized glass. The reason why he did not tell Ningmo about this plan was because there were two things he still wanted to do.
He was not sure, firstly, whether the raw materials for the production of glass-ceramics could be found in Hanping County, and secondly, whether there were people in the Hanping Glass Factory who knew the production process of glass-ceramics. He invited Su Changliang over because he wanted to verify these two aspects with Su Changliang.
Question, I didn’t expect that Su Changliang had the same idea as his hero. Not only did he think of a product like glass-ceramics, he even developed a sample.
"Chief Su, please tell me how you produced this piece of glass-ceramic. Also, how did you come up with the idea of studying glass-ceramic?" Qin Hai asked with great interest.
Su Changliang said: "It's a long story to tell. I also accidentally noticed the glass-ceramics when I was reading professional information. Some domestic companies are trying to use slag as a nucleating agent and co-solvent, combined with waste glass
Produced slag glass-ceramics. I saw that our steel plant also had a pile of slag, so I came up with this idea. I got some slag and started experiments in the laboratory of our factory. The hard work paid off, and I was really able to make it.
So many pieces of glass came out.”
Qin Haidao: "This is a coincidence. Titanium dioxide is indeed an excellent nucleating agent and co-solvent. When combined with the base glass of the sodium oxide-alumina-silica series, it can produce products with low expansion, high insulation and
Glass-ceramics with high wear resistance. Chief Su, how much ilmenite slag does our Hanping Steel Plant have now, and can it support the demand for large-scale production of glass-ceramics?"
"Absolutely." Su Changliang said, "Our iron ore in Hanping is ilmenite. The steel plant has been in production for decades, and the slag left behind is at least tens of thousands of tons. If we produce it on an annual scale of 30,000 weight boxes
Crystallized glass, these slags are enough to last for decades.”
"If that's the case, did you propose this plan to the factory before we came?" Qin Hai asked again.
Su Changliang sighed and said: "I have told our Factory Director Pang about this matter, and I have also shown him glass samples. However, there are still many obstacles to switching to the production of crystallized glass, and Factory Manager Pang is not willing to take the responsibility.
For this risk, the county cannot afford so much money."
"Then do you think we can afford this risk?" Qin Hai teased Su Changliang deliberately.
Su Changliang's face changed slightly and he said: "I am also a dead horse. Judging from what Qin Gong said to me this morning, I think Qin Gong is a person who understands glass. Qin Gong just saw this at a glance
It is a piece of glass-ceramics. This alone proves that Qin Gong understands the technology of glass-ceramics. To be honest, few people in our factory have even heard of the term glass-ceramics. If he hadn’t met Qin
I wouldn't take out this piece of glass and replace it with a layman, it would be considered a secret investment by me."
Qin Hai looked at the glass in his hand again and said: "Chief Su, with all due respect. Although you have produced this piece of crystallized glass in the laboratory, how strong is it? Can the thermal expansion coefficient meet the requirements?
I'm afraid the density has not been tested, right? 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 desperately and said: "I know, I know. To produce qualified glass-ceramics, many experiments must be done, and electron microscopes must be used for testing. Our factory does not have these conditions. Our factory director and I
It was proposed to allocate some funds for this matter, but he firmly refused, so the matter was shelved."
"If our group pays for it, please do the follow-up research, but the patents produced belong to our group, and the production can be handed over to Hanping Glass Factory. Would you like that?" Qin Hai asked tentatively.
Su Changliang hesitated for a second, then nodded solemnly and said: "I am already at this age, so why do I need a patent? If we can save our factory, my family's livelihood will be guaranteed, and I am willing to do this.
"
"If Section Chief Su has 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 to glass-ceramics, it will require a lot of investment.
It's very big, and Ning Mo and I can't make the decision immediately." Qin Hai explained with a smile.
Su Changliang said: "I understand, I don't know much about the specific production process of microcrystalline glass, but according to the information I have seen, it is estimated that we will have to invest at least 20 million to change our existing production process to microcrystalline glass.
We couldn't even think of such a large investment in glass craftsmanship in the past."
At this point, Su Changliang had nothing more to say. He ate for a while, then got up and left. Qin Hai did not persuade him to stay, but just asked Heizi to call a taxi to take Su Changliang back to the glass factory.
Seeing Su Changliang leaving, Ning Mo asked Qin Hai eagerly: "Qin Hai, is what you just told Lao Su true?"
"Of course it's true." Qin Hai replied angrily, "Old Su is already very old, can I play tricks on him?"
"What is the crystallized glass you are talking about? Can it be produced at 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 before. 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 for crystal nucleation agents. If Hanping Iron and Steel Plant can provide tens of thousands of tons of ilmenite slag, the problem of crystal nucleation 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 fisted his hands and was so excited that he was about to jump up. Being able to help his prospective father-in-law in a way that is beneficial to the group is of course the result Ning Mo hopes to see most. Otherwise, even if
He himself was willing to take out the money, but he also felt that his name was not legitimate and his words were inconsistent. When his little Qiqi asked him in the future, it would be difficult for him to answer.
Qin Hai looked at Ning Mo's expression and felt angry and funny. He didn't expect that Ning Mo, who had always been carefree, would fall in love and couldn't extricate himself. Moreover, like countless young people with nymphomaniacs, Ning Mo's IQ had dropped to kindergarten.
The level is completely unreasonable. However, Qin Hai is happy to see his buddy find happiness, so he is willing to spend some energy to promote this matter.
While talking, Heizi had returned. Qin Hai asked Heizi to sit down and told him: "Heizi, you have heard what I talked about with Lao Su just now. If the crystallized glass project is feasible, we must at least
Hanping Glass Factory has invested more than 20 million yuan, and must occupy 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. So the biggest problem now is that Hanping Glass Factory has
No one can take the lead anymore. Do you understand what I mean?"
Heizi nodded and said: "I understand, Mr. Qin, I will go to the glass factory tonight to thoroughly understand the situation in the whole factory."
"Be careful not to make any noise." Qin Hai warned him. After that, he turned to Ning Mo and said, "Fat man, let Heizi know about the things at the glass factory. Your father-in-law is going to treat us tonight. Let's go there again." Let’s talk to him.” (To be continued, please search Piaotian Literature for better and faster novels!
