TEK-IFB ALUMINA INSULATION FIRE BRICKS

Insulating Fire Bricks are applicable up to 1260, 1427 or 1538 C. They are light in weight and they have low thermal conductivity. They are made of  high pure refractor clay and other ceramic materials. They have uniform porosity distribution, uniform shape, and low Fe2O3 concentration because of producing from high purity materials.

 

Advantage:

Made from high purity raw materials.
Low dimensional tolerances.
Low thermal shrinkage.
High compressive strength.
Low thermal conductivity.
Can be used directly to heat sources.
High thermal shock resistance.
Low heat capacity because of low density.
Easy to use.

 

Typical Application Areas :

Combustion chamber,
Ceramic and porcelain furnaces,
In thermal operation furnaces which contain protective gaseous atmosphere,
Box type heat treatment furnaces,
As insulation layer in ladles,
As sidewalls in glass furnaces,
General industrial insulation.
