Product Information

Refractory clay thermal insulating fire brick  is a kind of insulation refractory product taking refractory clay as main raw  materials and including 30%~46% of AL2O3. It has a wide range of application and is mainly used in thermal equipment and insulation layer of industrial furnaces.

 

Key feature

1. Low bulk density, low thermal conductivity, good thermal insulation performance.

2. Refractory category allow direct contact of fire, suitable for various atmosphere.

3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely.

  

Application 

1. Furnaces of metallurgy industry, heat treatment furnace.

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace .
