Description

Fireclay bricks for stoves are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture.
 

Each face of the brick is machined to the required accurate size

  • Low thermal conductivity
  • Low heat capacity
  • Low content of impurities
  • High compressive strength
  • Accurate size.
  • The bricks can be processed into special shapes to avoid the joints and reduce the number of bricks.
Application

These bricks are widely used as the hot face linings on tunnel kilns and shuttle kilns. For most high temperature kilns, the kiln car platform is built using bubble alumina bricks. In most cases, the bricks are available in shapes such as rectangular, arch, end arch, key and wedge. Bricks with tongue and grooves are also available on request.
