Soon, ten minutes passed, and the glass that was put into the cooling furnace was finally cooled, but when the glass was slowly pushed out of the cooling furnace.

The faces of Wang Bin and the workers present were very ugly, because the glass in the molds that were pushed out of the cooling furnace had been shattered at this time, and they were still shattered into slag.

It was obvious that the workers must have overlooked something when smelting this furnace of glass.

Then Wang Bin immediately picked up some glass slag and looked carefully. He found that there were many black things in this furnace of glass. Obviously, according to the original data, it is absolutely impossible for these glass to appear. A black substance that can be seen even with the naked eye.

"Don't carry out re-smelting, please first check the electric melting furnace to see if there is any problem. I will go to conduct some tests on these failed products to see where there is a problem." After finishing speaking, Wang Bin took some The glass slag went to his own laboratory to test the glass.

After the inspection was completed, Wang Bin found that in addition to the black matter that could be seen by the naked eye, there were more things invisible to the naked eye in these glasses, which can be said to be everywhere in every corner of the glass.

At the same time, Wang Bin also tested these black substances, but the material elements displayed by these black substances are exactly the same as the materials of special glass, which makes Wang Bin a little puzzled. After all, the same material has the same smelting procedure and process, but How could this smelting fail inexplicably, and even a black substance appeared inexplicably in the glass.

After thinking for a while, Wang Bin didn't come up with a clue, so he walked out of the laboratory. He wanted to see how the workers were doing with the inspection of the electric furnace, and whether it was because of the electric furnace.

However, when Wang Bin came to the workshop and conducted a series of inspections on the electric furnace with the workers, he found that there was no problem with the electric furnace and all the equipment was very normal, which made Wang Bin even more unhappy. solved.

When the crackdown was at a loss, Wang Bin said to the workers: "Everyone, get ready, start smelting again, and check the situation of the second furnace. If the second furnace is still like this, then it is very likely that there is a problem with the material."

But in fact, Wang Bin still doesn't think it's a material problem. After all, the materials used today are the same batch as the materials used yesterday. The smelted glass stock solution is fine, but today's glass is not. Could it be that the materials are still divided into dates?

However, just as the workers were preparing to put quartz sand into the electric furnace, Wang Bin discovered something strange in the electric furnace.

Because the temperature in the electric melting furnace was still relatively high before, Wang Bin and the workers did not find any abnormalities in the electric melting furnace, but now that the electric melting furnace has completely cooled down, he found that the glass remaining in the electric melting furnace The stock solution has completely changed from dark red to black at this time.

So he immediately said to the workers: "Wait!"

"What's the matter? Mr. Wang! Did you find the problem?" The workers asked a little puzzled.

Wang Bin nodded, came to the side of the electric melting furnace, used pliers to take out some glass slag from the natural cooling of the glass stock solution in the electric melting furnace, looked carefully, and after a while, he finally told the workers Said: "When you started production this morning, didn't you clean up the remaining glass slag in the electric melting furnace when the glass was produced yesterday?"

After hearing what Wang Bin said, a worker asked: "Mr. Wang, do we still need to clean up the glass slag in the electric melting furnace?

If you have to clean up the remaining stock solution in the electric melting furnace every time you smelt a furnace, what a waste of materials! These materials are not cheap! Especially those rare materials. "

After hearing what the worker said, Wang Bin was a little speechless.

You must know that even ordinary glass, after the production is completed, the glass slag in the electric melting furnace will have a great impact on the next production of glass, and these workers were still producing glass handicrafts in Tiangong technology before. , and when a small amount of glass is produced, basically there is no need to clean the electric melting furnace. After all, the quality requirements of glass crafts are not so high. Even if there are some defects, it is irrelevant to crafts, let alone in crafts In the process of processing, these defects can also be dealt with.

But it's different now, what they produce is special high temperature resistant glass! During the production process, there must be no problems with all the procedures. If you are not careful, the entire furnace of glass stock solution will be scrapped just like this morning, and it will even affect subsequent production.

So Wang Bin already knew that the problem this time did not appear in the materials and equipment, but in the fact that the workers did not clean up the glass melting furnace thoroughly before the start of work today.

Of course, the workers also had good intentions. They were afraid that some materials would be wasted during the smelting process. In addition, when Wang Bin left yesterday, he did not explain clearly to the workers. This led to the smelting of the glass stock solution this morning. fail.

So he said: "Okay! I already know the reason, it is because the electric melting furnace was not thoroughly cleaned before it was started this morning, but it is also my fault that I didn't make it clear in advance.

In the future, everyone must remember the lesson of this time. Don’t ignore the details because of saving materials. In the future, after the first furnace is smelted, all the remaining slag in the electric furnace must be cleaned before proceeding to the next furnace. smelting.

At the same time, during production, especially when the first smelting furnace is started every morning, don’t be afraid of wasting materials. After all, there is no way to produce special glass. Otherwise, this furnace of glass this morning is the best lesson.

Well, everyone is an old worker of our Tiangong Technology, and I don't want to say anything more, as long as everyone knows it in their hearts! Let's get to work! "

After speaking, Wang Bin and the workers began to clean up the electric furnace. Soon, with the joint efforts of everyone, the electric furnace was cleaned up. Then Wang Bin let the workers start to put it into the electric furnace Raw materials, and start the electric furnace.

When the workers began to put materials into the electric furnace, Wang Bin also kept an eye on the situation in the furnace all the time, for fear that there would be any accidents during the smelting process, or that the black things before would appear again.

Fortunately, after cleaning the electric melting furnace, during the smelting process this time, there was no accident in the glass stock solution, and there was no abnormal color of the red glass stock solution.

An hour later, today's second batch of glass stock solution was finally released, and then the workers poured it into the mold and pushed it into the cooling furnace for cooling. Instead of smelting glass stock solution, first clean up all the remaining slag in the electric melting furnace, and then wait for the glass in the cooling furnace to cool down!

Soon the glass in the cooling furnace was completely cooled, and was pushed out of the cooling furnace. Wang Bin and the workers immediately stepped forward and inspected it carefully. The pieces of glass were intact and crystal clear. There is no special glass in the mold.

It is obvious that the glass produced this time is not the same as last time, and even in terms of quality, it can be seen with the naked eye that it is better than yesterday, which makes Wang Bin heave a sigh of relief.

However, he still picked up a piece of glass and entered his laboratory to test the batch of glass.

After the inspection was completed, Wang Bin finally felt relieved. The glass produced from this furnace was in an unexpectedly good condition, even almost comparable to that produced by Wang Bin's laboratory.
