High Quality Refractory Bricks High Alumina Brick 

  High alumina brick refers to fire brick containing Al2O3 more than 48%, which is made of high  grade bauxite through high temperature calcinations. High alumina brick is a kind of  neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is an ideal  material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.     High alumina brick specification
