Product Description

Special Shape Refractory Brick High Alumina Brick Fireclay Brick for Heating Furnace
The Description:
High alumina brick is a kind of high temperature refractory material, mainly made of high purity bauxite through melting, forming, drying and sintering and other processes, with good high temperature resistance, acid and alkali corrosion resistance and wear resistance. High alumina brick is widely used in furnace, kiln, converter, electric furnace, heat treatment furnace and other high temperature equipment to meet the use requirements under high temperature conditions. This paper will introduce in detail the manufacturing process, performance characteristics, application fields and other related content of high alumina brick.

Performance characteristics

(1) High temperature resistance: the high aluminum content and dense structure of high aluminum bricks make it have excellent high temperature resistance, and can be used for a long time in a high temperature environment without melting, softening, and expansion.

 

(2) acid and alkali corrosion resistance: high aluminum bricks contain a lot of aluminum oxide, so that it has good acid and alkali corrosion resistance.

 

(3) Wear resistance: The surface hardness of high aluminum bricks is high, and it is not easy to wear and break.

 

(4) Good thermal conductivity: high aluminum bricks have low thermal conductivity and excellent heat conductivity.
