Phosphate combined with high alumina refractory bricks specifications and size are very accurate with high temperature softening temperature, high compressive strength, thermal shock stability ,wear resistance and anti-peeling. It has the characteristics of stable performance, short construction period and energy saving. It is mainly used for calcining cement, bauxite, dolomite and other rotary kiln, the lining of the cooler, the working layer of the cement kiln, the top position of the steelmaking furnace and so on.
