Rebirth of Business Domination of the Two Worlds

Chapter 165 Manufacture of Refractory Bricks
Mo Mo turned to Li Gang and asked, "Uncle Li, have you found the clay that you were looking for a while ago?"

"Master, I've found several places of clay, but I don't know if the talisman meets your requirements." Li Gang replied, wrote down the location of the clay he had recorded on a piece of paper, and handed it to Mo Mo for review.

粘土砖的矿物组成主要是高岭土。粘土砖的烧成过程，主要是高岭石经1300～1400℃高温煅烧后，不断失水分解生成莫来石(3Al2O3·2SiO2)结晶的过程。

Clay bricks are also divided into many kinds. Among them, the refractory bricks used in masonry blast furnaces are alumina clay bricks. The alumina content index is not less than 42%, and the softening temperature is required to be not lower than 1450°C. Therefore, it is sufficient for ironmaking furnaces.

Mo Mo roughly looked at the record, then handed it back to him, and said with praise: "Well, yes, the engineering and construction department is responsible for making refractory bricks now, Fang Bo, you are in charge of this matter. Digging clay, digging brick cellars, and burning refractory bricks Waiting for the tutorial, there are teaching videos on the mobile phone.”

"Okay, I have learned the clay brick making process according to your plan, and I will organize and arrange work immediately after I finish the meeting."

Mo Mo was afraid that he would not be able to memorize and understand clearly, so he took out the materials of clay bricks, unfolded the drawings, and communicated with Fang Shi bit by bit.

For example, the mold of refractory bricks, the number of clay bricks, the location and size of brick cellars, moving tools, manufacturing techniques, etc. all need to be determined.

With the help of the system, Mo Mo will avoid many detours. What he is afraid of is that Fang Shi will misinterpret or even misunderstand the production process. Now that he has time, he can communicate with him, explain the technical details, and clarify the key points of the technology, so that the progress of the project will be faster. , they will not go in the wrong direction.

As for the details, Mo Mo didn't need to tell him clearly, and he didn't have the time.

This is what Mo Mo does. He is responsible for technical drawings and requirements, conducts technical clarification, checks out the key processes, and then the final acceptance.The supervisor is in charge of the supervision, and there is no need for him to do everything by himself.

The next morning, the person in charge of finding the clay brought back several samples. After Mo Mo tested them, he found that two samples were suitable for blast furnace refractory bricks, that is, there were two places.

One of them is in a shady area 15 miles southwest of the residential area, and it is also the most suitable for making blast furnace clay bricks recently.

Brick cellars are easy to build. Find a taller hillside with firmer soil and less prone to collapse as the site for the cellar, and then dig holes and make chimneys.

In order to prevent the residential area from being polluted, the brick cellar was built downstream of the river, about ten kilometers south of the residential area.

It is rare for Mo Mo to have leisure time, so he went to the scene to watch the digging and building of brick cellars.

The personnel in charge of digging the holes were ten members of the Flying Tigers and ten workers from the engineering construction team. As a military engineering training task, the Qinglong Group did not have any advanced tools. They used shovels for loose soil and iron picks for hard soil. Loose with a hoe.When encountering places where the soil is prone to subsidence, after the soil is solidified, build stone supports.

There are also some people who use molds to make clay bricks at the clay production site. After the bricks are dried, they are transported to the vicinity of the brick cellar by animal carts.

There are also some people who pull firewood for burning bricks.

"Master, we are digging dirty soil, so don't go near the brick cellar." Fang Shi, who was in charge, saw Mo Mo squatting outside the brick cellar, just in the place where the soil was piled up, and the dust was flying, and his body was covered with a layer Dust.

"It's okay, just go about your business, don't worry about me." Mo Mo looked at the dug out soil, it was really dry, and turned to Fang Shi to remind,
"By the way, the soil is dry, and there is a lot of dust in the hole. Let everyone wet a towel around the nose and mouth before digging the hole, or even spray the soil with water, otherwise the dust will enter the lungs, and it is easy to get dust disease. In the future, if you encounter this situation, you must Pay attention to protect your body, don't underestimate these dusts, if they accumulate, they will become diseases, and I don't have magic medicine to cure them."

"Okay." Fang Shi couldn't be more stubborn than Mo Mo, nodded and left to hurry. He had been in the cave just now, his body was covered in dust, his nostrils were black, and he felt uncomfortable.

There are many people and strength, and everyone is strong. The brick cellar to be dug is not very large. The cellar has a space of more than 1000 cubic meters. By the next day, the brick cellar will be ready.

It took a long time for the adobe to dry. Mo Mo didn't have to wait any longer. He asked someone to carry it over and dry it directly with firewood. This is also the fastest way, but it only costs firewood.

For Mo Mo, the cost is not a problem, the key is to grasp the progress and race against time to meet the deadline.

On the third day, it was ready to start firing bricks.

The adobes are stacked according to certain requirements in the brick kiln, the kiln door is sealed with bricks and mud, and then fired at the craters around the kiln.

It took three or four days to burn the bricks, and Mo Mo also left the brick kiln with special personnel watching.

While making clay bricks, the cement factory is also ready to start construction.

制造水泥的主要原料是石灰石（80％～90％，为质量分数，以下同）、粘土（10％～15％）和铁矿粉（1％～2％）。为了控制凝结速率），还要在熟料中加入3％以下的石膏。

Limestone is calcium carbonate CaCO3, the main component of marble, granite and other stones, which can be found everywhere.There is no crushing equipment in Caigu, and the hardness of marble and granite is too high, so it is better to find easy-to-break limestone as limestone raw material.

The purpose of adding gypsum to cement clinker is to delay the hardening rate of cement, to infiltrate enough, to make the cement evenly distributed, and to make the gel more and stronger.

The process of making cement is much more complicated than making clay bricks, especially if there is no electric equipment.

People who know a little about the cement production process will talk about "two grinding and one burning" when it comes to cement production, which are: raw material preparation, clinker calcination, and cement grinding.

This morning, Mo Mo took his mobile phone to communicate with Fang Shi and the others about cement production.

"Master, is this cement really so magical? It can firmly bond sand, stone and other materials together." Wang Dong, the deputy head of the engineering construction team, asked curiously. If it is shaped, the dam they intercept will not leak.

"Well, this thing is not magical, you will know when it is produced." Mo Mo said with a faint smile.

"Master, you just said that the process of making cement is a process of chemical reaction, so what exactly is chemical reaction?"

Mo Mo was silent for a while, and explained patiently: "Uh, what we usually see is accompanied by light emission, heat generation, discoloration, and formation of precipitates, all of which may have chemical reactions.

For example, when firewood burns, it means that the firewood reacts with the oxygen in the air. If there is no oxygen, such as the burning firewood, if you cover it with a bucket, will the firewood go out after a while? In fact, it is the oxygen in the air. there is none left. "

"Then what is oxygen? Why didn't I see it?"

Mo Mo further explained: "Oxygen is colorless and odorless. There are many gas components in the air, including oxygen, nitrogen, carbon dioxide and rare gases. If you hold your nose closed, it feels uncomfortable. In fact, there is no oxygen.

Just like yourself, you have bones, blood, flesh, and hair. Oxygen is like human blood. Without blood, you cannot live; nitrogen is like human flesh, accounting for most of it; and rare Gas is like human hair, it occupies a small amount and is dispensable. "

"Oh, I see, the young master is a real god, you know all about it!" Several adults raised their thumbs up in admiration.

Mo Mo waved his hand, and then continued to explain the production of cement to them, and explained the key points clearly. More details cannot be explained in a short time. There is a video of cement production on the mobile phone, and he gave the information to Fang Shi, let them research and produce by themselves.

The construction of the cement plant took a long time, and after Mo Mo was busy with these chores, the affairs of the other world were over.
