Use of Mullite Insulation Refractory Brick

Mullite Insulation Refractory Brick is high-alumina refractory materials with mullite (3Al2O3·2SiO2) as the main crystal phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the mineral composition with lower alumina also contains a small amount of glass phase and cristobalite; the higher alumina content also contains a small amount of corundum.
Mullite Insulation Refractory Bricks can be used at temperatures ranging from 1300°C to 1600°C with different materials. The body density can be between 0.5 0.6 0.8 0.9 1.0 1.2 1.5 according to user requirements. It acts on high-temperature kilns and directly touches the flame. Features high compressive strength and low thermal conductivity. It is suitable for the insulation of electric kilns, various high-temperature rotary kilns, tunnel kilns, nitrogen gas kilns, etc. The crystallization of fused mullite is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of mullite phase and glass distribution. Mullite bricks are mainly used for hot blast stove top, blast furnace body and bottom, glass melting furnace regenerator, ceramic sintering kiln, dead corner lining of petroleum cracking system, etc.
