Otaku Engineer in Great Tang Dynasty

"Is there no news from Xiaobin~?"

Qiquge new workshop.

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 iron smelting plant to Fu Bo, he basically didn’t bother much anymore, not because he was lazy, but Changan recently. Because of bean sprouts and spies in the house, a lot of his energy was involved.

"Master, that 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!"

Fubo replied with a smile.

He had previously received the news from Fubin, but wanted to report it to 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 that, 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 mines at their home more than a thousand years in advance!

"It's just 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 shipped back, here will begin to burn the kind of refractory cement I mentioned earlier with Fu Bo! 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 their composition. At this stage, the easiest to fire 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 certain high-temperature kilns and certain high-temperature projects that are long-term corroded by the atmosphere and rain .

Fu Bo nodded and said, "No problem~!"

When I asked Li Zexuan to get the drawings, Li Zexuan had already told him about the formula and production method of refractory cement. The workshop is no longer the same as in the past, and has accumulated a lot of technology. So Fuber felt that the refractory cement was fired. It should be no difficulty!

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. The craftsman takes the time to forge two for me!"

Uncle Fu 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 the ventilation performance of this thing. It’s better than the stove we’re using now! It’s just that this mold, and the things made with this mold, are like hornet’s nest with holes everywhere? What does the master want to use it for~?"

Li Zexuan smiled and said, "Fu Bo, how do you think of using it to shape coal powder~?"

The coal-making mold he provided to Fubo 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, this 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.

When he was six years old, his father did not know where he bought two large trucks of raw coal, the size of a football, probably just dug 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 without working, so even though his hands were sharpened It blistered, and he kept on doing it.

Later, after making briquettes for two years, their family did not continue 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 is quite different from the piston of the syringe in structure. Its "piston" is composed of two parts, one part is about twelve, etc. The iron pillars of the same diameter and height, and 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 move upward with the connecting rod. Moreover, due to the existence of the round 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 can be obtained!

The principle is really simple!

Fubo 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 master wants to make the briquettes into a honeycomb shape, so that the coal is easier to burn! This is true. It's a very 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 together if they stick together~!"

Li Zexuan gave a thumbs up and exclaimed: "Fu Bo has good eyesight! Ha ha! This coal powder does not have any stickiness as you said, but we can add some sticky things to it to make it stick! In this way, a honeycomb-shaped coal block 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~?"

Uncle Fu 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 while, he said with a look of admiration: "Master is really a talent. ! With such a fantastic idea, even if the old man is 40 years younger, I am afraid it is not as good as in case~!"
