Product Description
High Alumina Refractory Brick
High alumina brick is a kind of alumina-silicate refractory material with Al2O3 more than 48%. It is calcined and formed by high alumina bauxite clinker. High thermal stability, the refractoriness is more than 1770℃.
Key Features of High Alumina Refractory Brick
*High refractoriness
*High temperature strength
*High thermal stability
*Neutral refractory
*Good resistance to acid and basic slag corrosion
*High refractoriness under load
*High temperature creep resistance
*Low apparent porosity
Application:
Metallurgical Industry‌
Used as linings for blast furnaces, hot blast stoves, electric furnaces, ladles, and tundishes, effectively resisting material abrasion and high-temperature erosion. 
‌Building Materials Industry‌
Serves as a core material for high-temperature zones such as the burning zone in cement rotary kilns, the pool wall/chest wall of glass furnaces, and ceramic kilns. 
‌Chemical & Energy Industry‌
Suitable for sulfuric acid roasters, waste incinerators, and circulating fluidized bed boilers. 
‌Specialized Components‌
Customized components like regenerative checker bricks for open-hearth furnaces and pouring system nozzles
