Chapter 309 Fusion

These bricks are not like ordinary clay bricks - they are not solid.

The interior of the brick body is full of pores of various shapes, and the pores of each stack are different. It can be seen that someone is doing experiments.

And if Yang Dongsheng looked right, these were all internal combustion bricks.

The kind of clay brick we often see, the fuel is added from the outside, which is called external combustion brick.

The internal combustion brick is different, the fuel will be mixed with the clay and mixed into the brick. When it is baked in the kiln, no fuel can be added, or a small amount of supplementary fuel can be added to adjust the fuel.

Yang Dongsheng grabbed a brick and threw it on the ground.

bang!
Pretty solid, didn't break much.

Yang Dongsheng jumped up again and stepped on it.

At this time, several people in the room came out after hearing the sound, and Li Suqin introduced them to everyone.

It turned out that these people were all teachers from the University of Geology and Mineral Resources, and this project belonged to them.

These people are very young, generally around 30 years old, and the oldest one is only 35 or [-] years old.

After Yang Dongsheng asked, he found out that this was their own project. The site was an idle house in the school.

"What did you add as fuel?" Yang Dongsheng asked.

"We have added fly ash, slag, coal gangue, and mixed various fuels!"

This is the most prominent advantage of internal combustion bricks. Industrial waste can be used as fuel. This alone can reduce the fuel cost of each brick by more than 50%.

“Fuel costs can be further reduced by using an annular rotary tunnel kiln!” adds another.

The most common wheel kilns and tunnel kilns we see are that the kiln body does not move and the brick body moves.

The circular rotary tunnel kiln is the reverse. The kiln body is built on a ring-shaped rail, and the bricks are placed in a fixed position inside the rail.

The circular rotary tunnel kiln is divided into three sections: preheating, roasting, and cooling. The fan can pump the heat from the rear to the front for drying bricks. Therefore, unlike traditional kilns, bricks need to be dried after they are made.

The operation is good, the circular rotary tunnel kiln can work non-stop for 24 hours, and the efficiency is several times that of the rotary kiln.

"The black heart problem, the circular rotary tunnel kiln problem, have you all solved it?"

Because the fuel is inside the brick adobe, the pores of the adobe are too small, or if it is simply made into a solid adobe, it will not burn through and appear black. However, in order to ensure full combustion, if the internal pores are too large, it will become a hollow brick, and the hollow brick cannot be built. load bearing wall.

The annular rotary tunnel kiln is a new thing that has appeared in recent years. Although it seems to have many advantages, it also has many problems.

As the current largest kiln owner in Guazhou, Yang Dongsheng still has some understanding of these two things.

"We have considered these issues!"

For the circular rotary tunnel kiln, their method is to improve the automation level of the kiln and change manual operation to mechanical operation.

For the problem that solid adobes cannot be burned through, they proposed a multi-method solution, including adding combustion accelerants to the material, increasing oxygen externally, and improving the shape of adobes... As for whether to use only one or two, or All of these will depend on follow-up research.

But the cost of the next step of research was beyond the reach of a few poor scholars, so they found Yang Dongsheng.

Yang Dongsheng pondered for a while. According to the law of development in his previous life, within a few years, the country will introduce policies to restrict clay bricks, and finally ban the production of traditional clay bricks.

Since it is a matter of time to solve internal combustion bricks and circular rotary tunnel kilns, doing it later is worse than doing it early, especially these teachers seem to be saving money.

"I support your projects in principle! I will let Director Zhao of the company discuss how to cooperate with you." Yang Dongsheng said.

Saying goodbye to Li Suqin, Yang Dongsheng went to the library to read books about gemstones all day, especially about various gemstones in Australia, and borrowed some books to take back to the nursing home for reading.

As soon as I got home, the phone rang.

"Boss, good news! We have won the sapphire mine. We just completed the formalities today. Several other nearby mines are also in the process of contacting, and the progress is smooth!" Edward Jones said a little ostentatiously.

"Good job! But I think in addition to sapphire mines, we should also pay attention to other mines, such as opal and emerald!"

Reading the book today, Yang Dongsheng discovered that there are really many good things in Australia. In addition to iron ore, coal, and bauxite, which are well-known bulk minerals, Australia is also a source of many gemstones.

And rare things are more expensive, if Yang Dongsheng just grabs sapphires and makes as many sapphires as bricks, then the price of sapphires is bound to fall like bricks.

It is better to choose a few more!

Yang Dongsheng hung a world map and a map of Australia on the wall.

After selecting the ground, Yang Dongsheng pulled the map upwards.

Many places on the map are highlighted, which are Yang Dongsheng's land and mines.

Gradually, the entire map showed the outline of eastern Asia. It was the first time that Yang Dongsheng adjusted the map like this. It felt a bit like looking at an electronic map. At this time, there was only a small bright spot left on the map.

According to the instructions on the world map, Yang Dongsheng found Australia, and through the map of Australia, he successfully found Queensland and found a small bright spot in the east of Queensland.

Yang Dongsheng clicked on this small bright spot, selected aluminum oxide, and the three-dimensional map rose.

Whether it is sapphire or ruby, its main component is aluminum oxide.

What a coincidence, Yang Dongsheng just talked about clay bricks with someone this morning. One of the main components of clay bricks is aluminum oxide.

However, in addition to aluminum oxide, ruby ​​also contains some chromium oxide, so it appears red.

Sapphire, on the other hand, contains iron and titanium, which give it its blue color.

Yang Dongsheng put down the books he borrowed from the library, these damn books are all a virtue.

All the things are only half told, saying that iron and titanium are the cause of the blue color, and then the most precious cornflower blue in sapphire, from the place of origin to the history, and even listed several famous sapphires since 1979. The price of sapphire, but it just doesn't say how much iron and how much titanium should be contained in cornflower blue.

Yang Dongsheng could only experiment with some sapphires first, and he chose dozens of sapphires to move to one place.

But when Yang Dongsheng moved these dozens of sapphires to one place and was about to operate, he suddenly found that the number of these light spots had decreased by more than half. Although the number of light spots was less, the brightness was much greater than before.

It seems that these sapphires are fused!
