Otaku Engineer in Great Tang Dynasty Chapter 1028: Coal!
"Is there no news from Xiaobin~?"
The new workshop of Qiquge.
Li Zexuan looked at Fu Bo and asked.
Speaking of him, the owner is not responsible at all. A few days ago, after he handed over the drawings of the ironworks to Fu Bo, he basically didn’t bother much anymore. It’s not because he was lazy. It was the bean sprouts and spies in Chang'an that had involved a lot of his energy recently.
"Master, the kid sent a letter back two days ago, saying that he has found the clay mine you want, Master, in Shuozhou. He should send a batch back in these two days!"
Fu uncle replied with a smile.
He had received the news from Fubin before, and he wanted to tell Li Zexuan, but he had also heard about the recent ups and downs in Chang'an City, so he dispelled the idea and told Li Zexuan when he was free.
Li Zexuan was overjoyed when he heard this, and secretly thanked his memory that there was nothing wrong with it. It was just that some old classmates who were sorry for him had digged the mine at home more than a thousand years in advance!
"It is to continue the glory of the Chinese nation in the world. The aluminum ore donated by your old classmates is very meaningful!"
Li Zexuan murmured in his heart, and then said to Fu Bo: "Well, after the white clay mines in Shuozhou are transported back, here will begin to burn the kind of refractory cement I mentioned earlier to Fu Bo! If you have any questions, please 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 their composition. The easiest to fire at this stage is aluminate cement, which is mainly made of bauxite and limestone as raw materials, and is calcined to obtain clinker with calcium aluminate as the main component and about 50% alumina content. The hydraulic cementitious material made by grinding is called refractory cement.
The refractory temperature of refractory cement is generally above 1,580 degrees Celsius, so in modern society, refractory cement is often used as a refractory lining in some high-temperature kilns and some long-term erosion by the atmosphere and rain High temperature engineering.
Fubo nodded and responded: "No problem~!"
When I asked Li Zexuan to get the drawings, Li Zexuan told him the formula and production method of refractory cement. The workshop is now different from the past and has a lot of technical accumulation, so Fubo felt that firing There should be no difficulty in producing refractory cement!
Li Zexuan took out two drawings from his arms, handed them to Fu Bo, and said, "Fu Bo, I want to make two things recently. One is a stove and the other is a mold. The structure is not very complicated. Let the craftsmen below take time to forge two for me!"
Fu Bo took it suspiciously and took a glance. He understood what Li Zexuan wanted to make. He couldn't help asking, "Master, this stove is very delicate, especially for this thing. The ventilation performance is better than that of the stove we use now! It’s just that this mold, and the things made with this mold, are like hornet’s nests everywhere? Why do you want to use it~?"
Li Zexuan smiled and said: "Fu Bo, what do you think about using it to shape coal powder~?"
The coal-making mold he provided to Forber is the modern hand-made briquette mold with connecting rod punching. Many children in the city may not have seen this thing, but Li Zexuan in his previous life has not only seen it, but also used it. When he was a child, his family was poor. His father tried various ways to make money in order to support him and his sisters to study. Needless to say, the way of farming is needless to say. The other ways include fishing, selling dried fish, and helping others. I went to the streets to sell art when I was building a house or even in the slack period.
When he was six years old, his father didn't know where he bought two large trucks of raw coal, the size of a football, probably just dug out from a coal mine. After that, their family began to make money by making briquettes.
He was pretty sensible at that time, and would help his parents make briquettes every day after school. Rural children are not so squeamish. The hand-made briquettes molds are almost as tall as his height, but he also knew that his family was poor at that time, and he might not even be able to study if he didn't work, so even though his hands were sharpened It blistered, and he kept doing it.
Later, after making briquettes for two years, their family stopped making them because the manual efficiency was too low to make much money.
But because of that experience, Li Zexuan has an unforgettable familiarity with hand-made briquettes molds, and he can even draw them with his eyes closed.
This thing is simpler. It is similar to the principle of a syringe without a needle. The ground coal is mixed with yellow mud and "stuffed" into the mold, compacted, 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 briquette mold~IndoMTL.com~ is very different in structure from the piston of the syringe. Its "piston" is composed of two parts, one part is about twelve The iron pillars of equal diameter and height, the other part is an iron sheet with the same number, diameter and distribution position as the iron pillars.
The iron sheet with holes is nested on the iron post, and the push-pull connecting rod is connected with the iron sheet. In this way, when the "slime" is "stuffed" into the mold, the iron sheet will bring the connecting rod together Moving upwards, and because of the existence of the circular iron pillars, through holes will appear in the "slime". Finally, when the "slime" in the mold is pushed out through the connecting rod, a honeycomb-shaped coal block will be obtained!
The principle is really simple!
Fuber is also an expert in engineering. He frowned when he heard that, thought about it, and finally shook his head: "The old man understands that the young man wants to make the briquettes into a honeycomb shape, so that the coal is easier to burn. ! This is indeed a good way! But Master, have you ever thought that even if the coal is ground into pulverized coal, there is no stickiness between them, and it is difficult to stick to each other~!"
Li Zexuan gave a thumbs up and admired: "Fu Bo has good eyesight! Haha! This coal powder does not have any stickiness as you said, but we can add some sticky things to it to make it Adhesion! In this way, honeycomb-shaped coals can be made! Coupled with the stove on another piece of paper, Fu Bo, do you think it will be particularly convenient for us to boil water in the future~?"
Fu Bo couldn't help but startled, he realized that the two drawings Li Zexuan gave him were actually used in conjunction with each other. He thought about it in his mind, and after a moment, he said with a look of admiration: "Master What a genius! With such a fantastic idea, even if the old man is 40 years younger, he might not be as good as in case~!"
