Special Alumina Brick
Special alumina brick is a compact super-grade high-alumina brick with high compressive strength and high density. The firing temperature of this kind of high-alumina brick is similar to that of ordinary high-alumina bricks. It has low energy consumption and low cost. The service life of the kiln It is twice that of ordinary high alumina refractory bricks.
- High temperature resistance
- Customization
- Excellent thermal shock stability
- Extremely wear-resistant
Special Alumina Brick Description
Special high alumina brick is a kind of refractory brick made of bauxite as raw material and fired at high temperature. It has high alumina content and good slag resistance.It is mainly used for the lining of metallurgical furnace, such as electric furnace, open hearth furnace, converter, etc., and the lining of various thermal equipment, such as the regenerator of glass furnace, the wall of high–temperature stove, the combustion chamber of boiler, etc.

The Application Of Special Alumina Brick
Special alumina bricks are used in Electric Arc Furnaces (EAF) due to their high strength, thermal shock resistance and low thermal conductivity. The brick is designed to resist heat, slag attack and chemical attack from the furnace environment.
Special alumina bricks are used as lining materials in the hot zone of blast furnaces to provide protection from the heat and pressure generated by blast furnaces. It also has high wear resistance and is suitable for long-term use.
Special alumina brick is a kind of refractory material with high alumina content, which is widely used in glass furnace. It is mainly used for lining the bottom and side walls of the furnace, and also used for lining the ceiling and the bottom of the tank.
