Supply High Quality Fire Brick Mullite Insulation Brick

Fire clay mullite insulation brick
1.Low thermal conductivity
2.High hot compressive strength
3.Perfect Energy saving

 High Quality Fire Brick 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:

  The refractory linings of hot surfaces or backing heat-insulating layers of other refractory materials. The refractory 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.
