The craftsmen on the () side watched the whole thing. Although Zhong Jinwei did not eat with them in the end, this behavior was noticed by them. This Zhong Xingbo is really different!
After eating, the craftsmen went back to their residences to rest, and found that their families had been taken in by factory guards, and they also had another big pot of rice to eat. They couldn't help but feel even more grateful to Zhong Jinwei.
In the evening, this group of craftsmen gathered together to discuss what happened today, especially Zhong Jinwei. In addition to sighing, they also sighed, especially Wu Shengda, who was called Uncle Wu by the adults. In the end, everyone encouraged each other and must
Good job.
Zhong Jinwei felt that if he didn't finish it today, it should be almost done tomorrow. He stayed in the ceramics factory, which showed that he was dedicated. He just suffered a lot from the director of the Ministry of Industry and those officials. He didn't know what Mr. Zhongxing was up to. Although he couldn't see him, he didn't dare to leave.
, I had no choice but to sleep with him.
Unexpectedly, the cement manufacturing process was not going smoothly the next day. The situation was seriously beyond Zhong Jinwei's expectation. While working and observing the flame from time to time, he felt that it had reached the highest temperature in the furnace in the past. He breathed a sigh of relief. It shouldn't be.
Will live up to adults' expectations.
Because the raw materials for calcination this time were much smaller than the amount of ceramics fired in the past, the calcination time was also shorter than before, but to be on the safe side, it still took a whole morning.
Maybe it was to repay Zhong Jinwei, or maybe it was to have food and clothing, but the craftsmen were working very hard. Zhong Jinwei could see this and was looking forward to the results.
As a result, after the fire stopped and the temperature cooled down in the afternoon, the craftsmen went to the kiln to take out the lime-clay mixture and looked at each other. There was no change. It was obvious that the lime was still lime, and the clay was still clay.
This time, I gave Zhong Jinwei a blow and thought I was done, but in the end nothing changed.
Zhong Jinwei just sat on the chair, looking at the lime clay in front of him in a daze. The raw materials were these two items, he just didn't remember the proportions. If the conditions were met, the chemical reaction would definitely occur, and even if the proportions were wrong, at least part of it would occur.
Thinking from this point of view, it should be that the reaction conditions have not been reached, which means that the temperature is not enough. Thinking of this, Zhong Jinwei looked up at the craftsmen gathered around the raw materials, found Wu Shengda who looked frightened, and asked:
"Uncle Wu, can the temperature still be raised?"
Wu Shengda shook his head and said feebly to Zhong Jinwei: "Sir, the common people have been operating according to the highest temperature operation method. This time the temperature is already the highest."
"What about other places, such as places where iron is made and glass is burned, will the temperature be higher than here?" Zhong Jinwei asked unwillingly.
Wu Shengda still shook his head: "Sir, as far as the common people know, the furnace that can reach the highest temperature is this kind of inverted flame furnace."
Zhong Jinwei suddenly thought that the reason why cement was not invented in ancient China was because the temperature could not be reached, so no one could invent cement. Yes, it seems that glass could not be burned, which should be the same reason.
But at least glass has been burned in Europe for a long time, which means that the temperature reached by burning glass should not be difficult to achieve. Zhong Jinwei does not believe that Europe is hundreds of years ahead of the Ming Dynasty, and it is not the Manchu Qing Dynasty now.
Wu Shengda saw that Zhong Jinwei was worrying about the maximum temperature. He thought for a while and reminded Zhong Jinwei: "Sir, if you come to bake in summer, the temperature will be higher."
When Zhong Jinwei heard this, he stared at Wu Shengdao: "Can summer fever be higher? Can I add something?"
"No, the firing method remains the same. The temperature inside will be higher. This can be seen from the fired ceramics." Wu Shengda explained to Zhong Jinwei. The other craftsmen also nodded in agreement with Wu Shengda.
statement.
The operation method remains unchanged, but the temperature in the kiln will be higher in summer. Is it related to the climate? Zhong Jinwei began to think about the entire operation process of the craftsmen just now.
Zhong Jinwei suddenly slapped his thigh, stood up, and said excitedly: "I know the reason!"
An Guiyi was comfortably served by the director of the Ministry of Works and a group of officials outside the construction site. When he heard that the firing was unsuccessful, he left them alone and rushed over to see the situation.
As soon as he came over, he saw Zhong Jinwei standing up excitedly. He didn't understand the situation, so he flattered Zhong Jinwei: "Uncle Zhong Xing is indeed very knowledgeable. No difficulty can trouble you."
Zhong Jinwei glanced at him and didn't bother to talk to him. He said to Wu Shengdao who looked expectant at the side: "You just blow the air into the furnace. In such a cold weather now, the air blown in is too cold and will blow the air inside the furnace."
The temperature has dropped; and in the summer, the temperature of the air blown in is much higher than this temperature, so the temperature in the furnace will be different."
When Wu Shengda heard what Zhong Jinwei said, it was really true. He couldn't help but admired: "Your Excellency is indeed wise!"
Zhong Jinwei ignored their flattery and thought that the reason had been found. How to solve it? It was impossible to wait for the summer to bake. Moreover, even in the summer, with this little temperature difference, the temperature required for the chemical reaction of the cement would not be enough.
Naturally, Zhong Jinwei thought, if the air is heated first to a temperature higher than the summer temperature, and then sent into the kiln, the temperature will be higher. But how to heat it and how to send it to it?
Zhong Jinwei told the group of craftsmen in front of him his thoughts. Wu Shengda understood what Zhong Jinwei wanted to do, so he smiled and said to Zhong Jinwei: "Sir, this shouldn't be difficult. The fire kang at home actually has this principle. It can be done.
Let's try making one according to the method of making a fire bed at home." The other craftsmen also agreed. They gradually no longer feared Zhong Jinwei and began to show their sense of existence.
When Zhong Jinwei heard that there were ready-made cases for reference, this was the best, so he nodded and said: "Okay."
An Guiyi was also thinking about what would be better, but before he could think of it, Wu Shengda told him, and he felt a little annoyed. He was not as smart as this cheap man, so he solved it in one go.
Intake air temperature problem.
Suddenly an idea flashed in his mind, and An Guiyi quickly said to Zhong Jinwei: "Uncle Zhongxing, we also thought of something. Do you think it will be useful?"
"Oh, what did you think of?" Zhong Jinwei turned to look at him in disbelief.
"Since Mr. Zhongxing said that the temperature in the furnace will be affected when the air is taken in, will it also affect the temperature in the furnace when the air is discharged?" An Guiyi said a little proudly.
When Zhong Jinwei heard this, he slapped An Guiyi on the shoulder and praised: "Mr. An is really smart. I will definitely praise you in front of the emperor."
An Guiyi was suddenly photographed, and he was about to complain in his heart. When Zhong Jinwei said this, his face immediately turned into a smile, as bright as a flower. Is there any better reward than this?
After Zhong Jinwei finished speaking, he ignored him and said to Wu Shengda: "Bring your brains together and use your professional knowledge to quickly draw a sketch for me to take a look at, taking into account both the cooling of the inlet air and the solution of taking away the furnace temperature by the outlet air.
"
Wu Shengda was very happy to receive Zhong Jinwei's trust, and immediately left and took the craftsmen to discuss the drawings.
Zhong Jinwei wiped away his depression of not firing cement and happily chatted with An Guiyi.
After chatting for a while, Zhong Jinwei suddenly remembered that the key to firing cement, glass, and yes, steel in the future is the lack of sufficient high temperature. Now if Wu Shengda and the others want to make a new kiln for firing cement, they are afraid of glass.
and steel came out easily.
If it really succeeds, this new kiln needs to be kept secret compared to the cement formula. Zhong Jinwei mentioned this idea to An Guiyi.
An Guiyi thought for a while and said to Zhong Jinwei: "This ceramics factory has been out of use for a long time. Our family suggests that Zhongxing Bo propose to the emperor that this ceramics factory be directly renovated. Those irrelevant people can be expelled from the surrounding area.
Build a wall and use factories to guard it. Do you think this is good?" The irrelevant group of people An Guiyi refers to are the directors and officials of the Ministry of Industry outside. These people cannot be trusted and must be isolated.
Zhong Jinwei thought about it, this is okay. Then he can mention it to Emperor Chongzhen after the experiment is completed. It should be no problem.
In the evening, Wu Sheng came to Zhong Jinwei excitedly and showed the drawings he had drawn.
Well, Zhong Jinwei, a college student, didn't understand the drawings handed over by Wu Shengda, so Zhong Jinwei had to ask for an explanation.
Today I took the time to watch the ending of the theatrical version of "Proof of the Leader". I was a little bit sad, but it was the ending. I personally feel that this TV series is much better than the movie version, and I recommend it.
