55-65% Al2O3 Carbon roaster fire wall brick Special-shaped brick Fireway wall masonry
Carbon fired andalusite and mullite refractory brick for furnace wall is fired at 1500℃ by adding andalusite, mullite, kanite and other raw materials, which solves the defects of traditional refractory brick with high temperature creep rate, high porosity, low softening temperature under load and poor thermal stability, and greatly improves the high temperature volume stability performance of refractory brick. It is the ideal product to extend the life of baking furnace.
▌FEATURES
1. High temperature resistance；
2. High compressive strength；
3. High temperature creep resistance is superior；
