refractory brick
Product Detailed

clay refractory brick consist of fire clay and binder. The chemical components of these bricks are SiO2 and Al2O3

Clay 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

 

The main applications 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 clay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before
