Clay refractory brick is a kind of widely used fire resistance, and the material is used in many industrial fields because of its good fire resistance, thermal shock resistance and economy. The following are the main uses of clay refractory bricks:

I. Metallurgical industry

Coke oven: Clay refractory brick is one of the main refractory materials of coke oven, which is used to build the carbonization chamber, combustion chamber, chute area and other parts of coke oven. Its fire resistance and corrosion resistance can withstand the working environment of coke oven under high temperature, high pressure and frequent temperature changes.

Blast furnace: used in the shaft and bottom of blast furnace, which can withstand the erosion of high temperature molten iron and slag.

Hot blast stove: used in the vault, furnace wall and other parts of hot blast stove, which can withstand the erosion of high temperature airflow.

II. Glass industry

Glass melting furnace: clay refractory bricks are used in the wall and bottom of glass melting furnace. Its good corrosion resistance can withstand the corrosion of molten glass, while maintaining the stable operation of the furnace.

Annealing furnace: used for the furnace wall and roof of glass annealing furnace, which can withstand high temperature and frequent temperature changes.

III. Cement industry

Cement rotary kiln: Clay refractory bricks are used as kiln lining of cement rotary kiln, which can withstand high temperature and chemical erosion while maintaining the structural stability of kiln body.

Preheater and cooler: used for the lining of preheater and cooler, which can withstand the erosion and thermal shock of high temperature airflow.

IV. Ceramic industry

Ceramic kiln: used as the lining of ceramic firing kiln, which can withstand chemical erosion and thermal shock during high temperature firing.

Tunnel kiln: used for the vault and side wall of tunnel kiln, which can maintain the structural stability and temperature uniformity of kiln body.

V. Chemical industry

Chemical furnace: used as the lining of chemical furnace, which can withstand high temperature and chemical medium erosion, such as sulfuric acid furnace and nitric acid furnace.

Reaction kettle: used as the lining of reaction kettle, which can withstand the erosion of high temperature and chemical reaction.

VI. Power industry

Boiler: Used in the furnace wall, furnace bottom and other parts of the boiler, which can withstand the erosion and thermal shock of high temperature flue gas.

Garbage Incinerator: Used for the lining of garbage incinerator, which can withstand the erosion of high temperature and corrosive gas.

VII. Other industrial areas

-Ceramic fiber furnace: used as the lining of ceramic fiber furnace, which can withstand high temperature and chemical erosion.

Heating furnace: lining for metal heating furnace, which can withstand high temperature and corrosion of molten metal.

Ceramic brick kiln: It is used as the lining of ceramic brick firing kiln, which can withstand the chemical erosion during high temperature firing.

VIII. Civil buildings

Kiln: used for masonry of small kilns, such as ceramic handicraft kilns and glass kilns.

Household stove: used as the lining of household stove, which can withstand high temperature and frequent temperature changes.

IX. Summary

Clay refractory bricks are widely used in metallurgy, glass, cement, ceramics, chemical industry, electric power and other industrial fields because of their good fire resistance, thermal shock resistance and economy. It is versatile and can meet the needs of different industrial furnaces under complex working conditions such as high temperature, high pressure, chemical erosion and frequent temperature changes.
