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.
