Mullite Insulation Kiln Refractory Bricks In Lining Or Heat Insulating Materials
Description:
mullite insulation 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 chemical demands.
Applications:
Mullite insulation 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
