Product Description

Wholesale Sk32 Sk34 Sk36 Sk38 Fire Brick for Industrial Furnaces

 

Product Description

 

Fireclay bricks use Chamotte that the fire clay is calcinated as the main material. These bricks consist of fire clay and binder. The chemical components of these bricks are SiO2 and Al2O3. (Al2O3=25~40%) fireclay bricks are cheap so that they are used for all kinds of industrial furnaces.

The main applications of fire clay brick are the low temperature parts such as blast furnaces and hot blast furnaces, waste incinerators and glass melting furnaces. Due to the scale-up of a variety of industrial furnaces and severity of operating conditions, super dense fireclay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before.
