High Alumina Brick

High alumina (Al₂O₃) is the main component of the refractory.

High alumina refractories have a high alumina content, which can be divided into several grades according to different content. Generally speaking, alumina content between 48% and 75% belongs to high aluminum refractory. Its main raw material is high bauxite or industrial alumina.

It has a high refractoriness, usually between 1750℃ and 1790℃, which makes it able to withstand high temperature environments, such as the transition zone and firing zone of cement rotary kilns, the lining of ceramic kilns and other high temperature parts play a key role.

High Alumina Brick

Features:
High alumina brick is a kind of neutral refractory material, which is formed and calcined by bauxite or other raw materials with high alumina content. It has high thermal stability and strong corrosion resistance.
Application:
High alumina brick is mainly used in blast furnace, electric furnace, blast furnace, reverberatory furnace, glass furnace, cement rotary kiln lining and so on.
