Lightweight Mullite IFB Refractory Brick

Lightweight Mullite IFB Refractory Brick

Mullite insulation brick is a high-alumina refractory brick with mullite as the main crystal phase. It has uniform thermal expansion, heat insulation, high temperature resistance, and good chemical corrosion resistance. It is used in hot blast furnaces, metal melting furnaces, forging furnaces, etc.

Mullite insulation brick introduction
Mullite insulation bricks are high alumina refractories with mullite as the main crystal phase. The bulk density of lightweight heat-insulating brick is 0.60～1.25g/cm3. Working temperatures range from 900℃ to 1600℃ the refractory of mullite brick is relatively high, reaching above 1790 ℃. The starting temperature of load softening is 1600 ~ 1700 ℃. Good thermal shock resistance.

lightweight heat-insulating bricks are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades.this material profitable by lessening fuel costs, construction costs and reducing the amount of time spent in the high temp furnace
