High quality factories refractories material alumina 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.
High quality factories refractories material alumina brick is one kind of High alumina refractory brick.The High alumina refractory brick is an aluminum silicate material which content of more than 48% alumina. It is formed and calcined from alumina or other raw materials with high alumina content. The advantage of this material are high thermal stability, refractoriness above 1770℃,good slag resistance.
JHigh quality factories refractories material alumina brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.
Features:
