Specifications
Fire clay bricks with good high temperature resistance capability, widely used for boilers and different kilns and furnaces.High Tempreture Working Fire Brick
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.
