Product Description
Fireclay bricks
is Al2O3 content of 42% to 45% 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 ℃. 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.
1.Excellent strength at ambient and elevated temperatures.
2.High compressive strength.
3.Very low levels of iron and other impurities.
4.Lightweight and energy-efficient.
5.Lower heat storage than denser refractory.
6.Heats quickly and economically to operating temperature.
