Fire Brick High Alumina Brick For Furnance
High alumina brick packing
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.
