High alumina refractory brick is a kind of neutral refractory material with alumina content above 48%, which has high refractoriness, good corrosion resistance and thermal stability and is widely used in many industrial fields. The following are its main uses:

I. Steel industry

High alumina refractory bricks are mainly used in blast furnace, hot blast stove, electric furnace top, ladle, tundish and heating furnace in iron and steel production. Its high refractoriness and corrosion resistance can effectively resist the corrosion of high temperature slag and molten steel.

II. Cement industry

In cement production, high-alumina refractory brick is an ideal material for firing zone, transition zone and decomposition zone of cement rotary kiln, which can withstand high temperature and chemical erosion. In addition, it is also used in kiln door cover and cooler.

III. Glass industry

High-alumina refractory bricks are used in the lining of glass melting furnace, which can resist the high-temperature erosion of glass melt and ensure the stable operation of the furnace.

IV. Non-ferrous metallurgical industry

In non-ferrous metallurgy, high-alumina refractory bricks can be used in melting furnaces, refining furnaces and other equipment to resist the chemical corrosion of non-ferrous metal melt.

V. Petrochemical industry

High alumina refractory bricks can be used in high temperature reaction devices in petrochemical industry, such as cracking furnaces and reforming furnaces, to provide reliable high temperature protection.

VI. Other high-temperature equipment

High-alumina refractory bricks are also widely used in the lining of high-temperature equipment such as ceramic kilns, lime kilns, coke ovens and boilers, as well as open-hearth regenerative checker bricks, plug heads and nozzle bricks for gating systems.

Because of its excellent performance, high-alumina refractory bricks are indispensable in high-temperature industry, which can effectively improve the service life and operation efficiency of equipment.
