The brick is made from sintered special grade high alumina bauxite, phosphate acid as binder, with high thermal stability and strength.Be applied in preheating zone,calcine zone,firing hood and cooler part of cement kiln.
The brick is made from sintered special grade high alumina bauxite, added with zirconia, silimanite and andalusite by reasonable ration, pressed by high pressure and sintered at high temperature, with excellent spalling resistance, alkali, sodium, sulfur, chlorine and alkalic salt corrosion. Low thermal conductivity, a better and ideal choice for transition and calcining zone of cement kiln.
