Furnace Insulating High Temperature Refractory Bricks Fire Retardant SGS
Mullite Lightweight white insulating fire brick used for industrial furnace
1. Description of Mullite lightweight insulation fire brick
Mullite lightweight insulation brick has small holes inside it, so it has high apparent porosity.Mullite lightweight insulation brick can decrease heat loss of furnace wall, then save fuel.Meanwhile, lightweight means less heat storage, fast temp-up and temp-down, which can increase cyclic operation.
2. Feature of Mullite lightweight insulation brick
Mullite lightweight insulation brick has High purity, small impurities,low thermal capacity.
Low thermal conductivity, high strength, good thermal resistance , strong anti-corrosion.
