Mullite Insulation Brick

 

Description:

  Lightweight mullite refractory bricks are made from good quality and superpure 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 grade of products has unique design to meet different thermal, physical and chomical demands.

 

Application:

 Mullite insulation brick can be used in linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc

 

Mullite Insulation Brick can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much
