"Is there no news from Xiaobin~?"
Qiquge new workshop.
Li Zexuan looked at Uncle Fu and asked.
Speaking of which, he is not responsible at all as a boss. A few days ago, after he handed over the drawings of the ironworks to Uncle Forbes, he basically never bothered him again. It was not because he was lazy, but because of the recent changes in Chang'an. Over there, the matter of Dou Ya and the spies in the house involved a large part of his energy.
"Master, that boy sent a message back two days ago, saying that he has found the white clay mine you want in Shuozhou, Master. He should send a batch back in the next two days!"
Fu Bo replied with a smile.
He had received the news from Fu Bin before, and wanted to report it to Li Zexuan, but he also heard about the recent ups and downs in Chang'an City, so he gave up the idea and thought of telling Li Zexuan when he was free.
Li Zexuan was overjoyed when he heard this, and secretly rejoiced that his memory was indeed correct, but he just felt sorry for his old classmates, and dug up their mines more than a thousand years in advance!
"Just think that it is to continue the glory of the Chinese nation in the world. The aluminum ore donated by your family, old classmates, is very meaningful!"
Li Zexuan muttered in his heart, and then said to Uncle Fu: "Well, after the white clay mine from Shuozhou is shipped back, we will start firing the refractory cement I told you about before, Uncle Fu! What's the problem? , send someone to call me at any time!”
The so-called refractory cement can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement according to different compositions. The easiest thing to fire under current conditions is aluminate cement. It is mainly made of bauxite and limestone as raw materials. It is calcined to produce clinker with calcium aluminate as the main component and an alumina content of about 50%. Refractory cement is ground into a hydraulic cementitious material.
The refractory temperature of refractory cement is generally above 1,580 degrees Celsius. Therefore, in modern society, refractory cement is often used as a refractory lining in some high-temperature kilns and in some high-temperature projects that are subject to long-term erosion by the atmosphere and rain. .
Uncle Fu nodded and said, "No problem~!"
When he asked Li Zexuan to get the drawings, Li Zexuan had already told him the formula and production method of refractory cement. The workshop is now different from the past, and it has accumulated a lot of technology, so Fu Bo felt that it would be possible to bake refractory cement. It shouldn’t be difficult!
Li Zexuan took out two drawings from his arms, handed them to Uncle Fu, and said: "Uncle Fu, I want to make two things recently, one is a stove, and the other is a mold. The structure is not very complicated. You can just ask the following Just give the craftsman time to help me forge two!"
Uncle Fu took it suspiciously, and after a quick glance, he understood what the thing Li Zexuan was going to build looked like. He couldn't help but ask, "Master, this stove is quite exquisite, especially its ventilation performance. It’s better than the stove we use now! It’s just this mold, and the things made with this mold, aren’t they like a hornet’s nest with holes everywhere? What on earth does the young master want to use it for~? "
Li Zexuan smiled and said: "Uncle Fu, what do you think of using it to shape coal powder~?"
The coal-making mold he provided to Forber is a modern connecting rod stamping type hand-made briquette mold. Many children in the city may have never seen this thing, but Li Zexuan in his previous life not only saw it, but also used it. His family was poor when he was a child. In order to support him and his sisters in studying, his father tried various ways to make money. Not to mention farming, other ways include fishing, selling dried fish, and helping others. While building a house, he even went to the streets to perform during his spare time.
When he was six years old, his father bought two large trucks of raw coal lumps from somewhere, the kind of coal the size of footballs, which must have been freshly dug out of the coal mine. After that, their family began to make money by making briquettes.
He was quite sensible at that time and would help his parents make briquettes every day after school. Children in rural areas are not so squeamish, and the handmade briquette molds are almost as tall as him. But at that time, he also knew that his family was poor, and if he didn't work, he might not even be able to go to school, so even though his hands were polished, Even though it was bubbling, he kept on doing it.
Later, after two years of making briquettes, their family stopped doing it because the manual work was too inefficient and they couldn't make much money.
But precisely because of that experience, Li Zexuan is deeply familiar with handmade briquette molds and can even draw them with his eyes closed.
To put it simply, this thing is similar to the principle of a syringe without a needle. Ground coal mixed with yellow mud is "stuffed" into the mold, tamped, and then pushed out by the "piston" and dried to form.
It's just that the "piston" at the end of the push rod of the honeycomb mold is very different in structure from the piston of the syringe. Its "piston" is composed of two parts. One part is about twelve iron pillars of equal diameter and height, and the other part is an iron piece with the same number, diameter, and distribution position as the iron pillars.
The iron piece with holes is nested on the iron column, and the push-pull connecting rod is connected to the iron piece. In this way, when the "slime" is "stuffed" into the mold, the iron piece will move upward with the connecting rod. And due to the existence of the round iron pillars, through holes will appear in the "coal slime". Finally, when the "coal slime" in the mold is pushed out through the connecting rod, honeycomb-shaped coal blocks will be obtained!
The principle is really simple!
Uncle Fu is also an expert in engineering. He frowned when he heard this, thought for a while, and finally shook his head and said: "I understand that the young master wants to make the shape of the briquettes into a honeycomb shape, so that the coal will burn more easily! This is indeed It’s a good idea! But has the young master ever thought that even if the coals are ground into coal powder, they are not sticky to each other and it is difficult to stick together~! "
Li Zexuan gave a thumbs up and praised: "Uncle Fu has great eyesight! Haha! This coal powder is indeed not sticky at all as you said, but we can add some sticky things to it to make it stick! In this way, we can make honeycomb-shaped coal! Combined with the stove on another piece of paper, Uncle Fu, do you think it will be particularly convenient for us to boil water in the future~?"
Uncle Fu couldn't help being startled. Only then did he realize that the two drawings Li Zexuan gave him were used in conjunction with each other. He thought about it in his mind. After a while, he said with admiration: "Young Master is really a great talent. ! Such a fantastic idea, even if I am forty years younger, I am afraid it is not as good as the worst case~!"
