Super Quality Insulation Fire Brick For Kiln fireproof board

Super Quality Insulation Fire Brick For Kiln fireproof board Fire Brick Introduction   Fireclay bricks is Al2O3 content of 30% to 40% aluminum silicate clay material products, with 50% clay and 50% soft hard clay clinker, As the size requirements for certain ingredients,   after forming, drying, firing at a high temperature of 1300 ~ 1400 ℃. temperature of 1300 ~ 1400 ℃. common brick, special-shaped brick. They are widely applied in coke oven,   blast furnance, air stove, molten steel ladel, gating system, boiler, cement kiln, glass kiln, kinds of kiln lining and thermal equipment.
