Application scope of high-purity corundum bricks

Refractory materials industry: High-purity corundum bricks are treasures in the field of refractory materials. They are widely used in the lining of high-temperature industrial equipment such as furnaces, converters, electric furnaces, and crucibles, effectively ensuring long-term stable operation of equipment in high-temperature environments.

Steel smelting: In the steel smelting process, high-purity corundum bricks are an indispensable lining material. They have excellent fire resistance and corrosion resistance and can withstand harsh environments at high temperatures.

Aluminum electrolytic cell: In the aluminum electrolysis industry, high-purity corundum bricks can be used as lining materials for electrolytic cells. Because of their stability at high temperatures, they can effectively resist high-temperature erosion during the aluminum electrolysis process.

Glass furnace: High-purity corundum bricks can be used as the lining of glass furnaces. Its high melting point and excellent heat resistance enable it to withstand the corrosion of high-temperature molten glass in the glass furnace.

Chemical industry: In high-temperature, highly corrosive chemical environments, high-purity corundum bricks also play an important role and are used to manufacture the linings of reactors, catalyst carriers, and other equipment.
