Production process:
High Alumina Fire Brick Refractory Material Brick are mainly made from chamotte, being high pressure pressed and sintered in high temperature. Main minerals compositions are mullite phases. These products are widely used in all parts of furnace lining for middle and small capacity blast furnaces because of their excellent physical and chemical properties in high temperature. It also can be used in lining for other kinds of furnace.
Production practice proves that high-alumina clinker is strictly selected and classified before crushing, and is stored in tiers. The co-fine grinding method of bauxite clinker and combined clay can improve the quality of high-alumina refractory brick
Aluminum oxide (Al2O3) content of the High Alumina Fire Brick Refractory Material Brick is more than 48%
A neutral refractory with an alumina content of more than 48%.Made of bauxite or other raw materials of high alumina content after molding and calcining.High thermal stability, refractoriness in 1770℃ above.Good slag resistance, used for lining steelmaking electric furnace, glass furnace, cement converter, etc.
