"Is there still no news from Xiao Bing?"
Strange Taste Pavilion's new workshop.
Li Zexuan looked at Faubert and asked.
Speaking of which, as the owner, he was not responsible at all. A few days ago, after he gave the blueprint of the ironworks to Faubert, he basically did not ask about it anymore. It was not because he was lazy, but because of the sprouts and the spies in Chang 'an, which took up a lot of his energy.
"Young master, that guy sent a message back two days ago, saying that he had found the bauxite you wanted in Shuo Province. He should be sending a batch back in two days!"
Faubert replied with a smile.
He had received the news from Fubin and wanted to report it to Li Zexuan, but he had heard about the recent turmoil in Chang 'an City, so he gave up the idea. He wanted to wait until Li Zexuan was free to tell him.
Li Zexuan was happy to hear that. He was secretly glad that his memory was not wrong, but he felt sorry for his old classmate. He had dug up his family's bauxite more than a thousand years in advance!
"Just take it as a continuation of the glory of the Chinese people in the world. Old classmate, the bauxite that your family contributed is very meaningful!"
Li Zexuan muttered in his heart, and then said to Faubert, "Well, after the bauxite from Shuo Province is shipped back, we will start firing the refractory cement that Faubert and I talked about previously! If there are any problems, send someone to call me at any time! "
The so-called refractory cement could be divided into aluminate cement, low-calcium aluminate cement, calcium-magnesium aluminate cement, and dolomite refractory cement. At present, the easiest cement to fire was aluminate cement, which was mainly made of bauxite and limestone. It was calcined to produce a clinker with calcium aluminate as the main component and alumina content of about 50%. After that, it was ground into a hydraulic cementitious material, which was called refractory cement.
The refractory temperature of refractory cement was generally more than 1,580 degrees Celsius, so in modern society, refractory cement was often used as the lining of some high-temperature kilns and some high-temperature projects that were eroded by the atmosphere and rain for a long time.
Faubert nodded and replied, "No problem!"
When he had asked Li Zexuan for the blueprint, Li Zexuan had already told him the formula and production method of refractory cement. The workshop was no longer the same as before, and had accumulated a lot of technology, so Faubert felt that it should not be difficult to fire refractory cement!
Li Zexuan took out two blueprints from his arms and handed them to Faubert. He said, "Faubert, I want to make two things recently. One is a furnace, and the other is a mold. The structure is not very complicated. You can just ask the craftsmen to help me make two of them!"
Faubert took them suspiciously and roughly glanced at them. He roughly understood what Li Zexuan wanted to make. He couldn't help but ask, "Young master, this furnace is very delicate, especially the ventilation performance of this thing. It's better than the furnaces we use now! But this mold, if you use this mold to make something, won't it be like a hornet's nest with holes everywhere? What do you want to use it for, young master? "
Li Zexuan smiled and said, "Faubert, what do you think of using it to shape coal powder?"
The coal mold that he provided to Faubert was the kind of modern hand-made honeycomb coal mold that was used for pressing connecting rods. Many children in the city might not have seen this kind of thing before, but Li Zexuan in his previous life had not only seen it, but also used it. When he was young, his family was poor. His father tried all kinds of ways to earn money in order to provide for him and his sisters to go to school. There was no need to talk about the way to earn money. Other ways included fishing, selling dried fish, helping others build houses, and even going to the streets to sell his art when he was not in the fields.
When he was six years old, his father bought two trucks of raw coal from somewhere. It was the kind of coal that was the size of a football. It was probably just dug out from a coal mine. After that, his family began to rely on making honeycomb coal to earn money.
At that time, he was still quite sensible. Every day after school, he would help his parents make honeycomb coal. The children in the countryside were not so delicate. Those hand-made honeycomb coal molds were almost as tall as him. But at that time, he also knew that his family was poor. If he did not work, he might not even be able to go to school. So even though his hands were blistered, he continued to work.
Later, after making honeycomb coal for two years, his family did not continue to do it. Because the efficiency of manual labor was too low, they did not earn much money.
But it was also because of that experience that Li Zexuan was very familiar with the honeycomb coal mold. He could even draw it with his eyes closed.
To put it simply, it was a bit similar to a syringe without a needle. Ground coal mixed with yellow mud was "stuffed" into the mold, compacted, and then pushed out by the "piston" and dried to form the mold.
The only difference was that the "piston" at the end of the honeycomb coal mold's push rod was very different from the piston of a syringe. The "piston" was made up of two parts. One part was about twelve iron pillars of equal diameter and height. The other part was an iron plate with the same number, diameter, and distribution as the iron pillars.
The iron plate with holes was embedded in the iron pillars, and the push rod was connected to the iron plate. In this way, when the "slime" was "stuffed" into the mold, it would cause the iron plate to move up with the connecting rod. And because of the existence of the circular iron pillars, there would be holes in the "slime". Finally, when the connecting rod pushed out the "slime" in the mold, the honeycomb-shaped coal would be obtained!
The principle was very simple!
Faubert was considered an expert in engineering. When he heard this, he frowned and thought for a while. Finally, he shook his head and said, "I understand. Young Master wants to make the shape of the coal into a honeycomb shape, so that the coal can burn more easily! This is indeed a very good idea! But has Young Master ever thought that even if the coal is ground into coal powder, there is no adhesion between them. It is very difficult to stick together! "
Li Zexuan gave a thumbs up and praised, "Faubert has good eyesight! Haha! This coal powder is indeed as you said, there is no adhesion. But we can add something sticky to it to make it stick together! In this way, we can create honeycomb-shaped coal! Together with the stove on the other paper, Faubert, do you think it will be very convenient for us to boil water in the future? "
Faubert couldn't help but be startled. He finally understood that the two drawings that Li Zexuan gave him were actually used together. He thought for a while, and after a while, he said with a face full of admiration, "Young Master is really a genius! This kind of wonderful idea, even if I were forty years younger, I am afraid I would not be able to come up with it! "
