Advantage of Refractory JM Mullite Insulation Brick
1. Low thermal conductivity
2.High hot compressive strength
3.Perfect Energy saving
Description of Refractory JM Mullite Insulation Brick
Lightweight mullite kiln bricks refractory for sale 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 of Refractory JM Mullite Insulation Brick
Mullite insulation furnace bricks refractory material 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 furnace refractory material can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much
