Product information:
High alumina brick is formed by bauxite or other raw material with high Al2O3 which after forming and calcination.It have excellent thermal shock resistance and good slag resistance;its refractoriness is more than 1770 ℃ .
It mainly used for blast furnace,hot blast stove, electric furnace roof,reverberatory furnace,glass furnace,cement kiln ,lining of rotary furnace. In addition, high alumina bricks are widely used as open hearth regenerative checker brick, plug head of pouring system ,nozzle brick, etc.
