alumina cement

Main introduction of the High alumina bricks 

High alumina brick, also known as high alumina fire bricks or high alumina refractory bricks, 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 a n 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.
