Brief introduction and Application:
Fire clay bricks also called sinterd clay bricks, are alumina silicate bricks with the refractoriness of SK 26-38 and contain 35- 55% alumina. Refractory fire clay brick are made of super calcined flint clay and calcined bauxite, with high Pressure formed and high temperature sintered.
Due to its low apparent porosity, strong resistance to erosion and high refractoriness under load. It is mainly used for carbon furnace, baking furnace, heating boiler, glass furnace, cement kiln, fertilizer gasification furnace, blast furnace, the hot blast stove, coking furnace, furnace, casting and casting steel brick, etc.
