Fire Clay Bricks in Rongsheng Kiln Refractory Company, a kind of cheap refractory bricks, are manufactured with fire clay (30%~40% content of Al2O3) as the raw material, mixed and fired in the high temperature of 1300~1400℃ after molding and drying. Fire Clay Bricks have various properties of strong chemical erosion resistance and thermal conductivity resistance, which are mainly used in the secondary position of coke oven, such as regenerative chamber regenerative chamber, fire door lining brick, furnace top and ascension pipe lining brick.

The refractoriness of fire clay bricks is about the same with silica brick reaching up to 1690~1730℃ and its refractoriness under load is lower 200℃ than silica brick. Because there are also almost half low-melting-point amorphous glass phase except for high-refractory mullite crystal.
