High alumina brick is a kind of refractory material, one of the main composition of the refractory brick is Al2O3. The Al2O3 content is higher than 48% of the silicate aluminum refractory products.
It is formed by alumina or other higher raw material forming and calcined alumina content. Thermal stability, high refractoriness is more than 1770 ℃. It has good slag resistance and used for building steel-making furnace, glass furnace, and cement rotary kiln lining. The high alumina bricks is mainly used in lining of blast furnace, the hot blast stove, electric furnace roof, furnace and reverberatory furnace, rotary kiln lining. In addition, high alumina brick is widely used for open hearth regenerative checker brick, pouring system with the plug head, nozzle brick, etc.
