Description

Magnesia Aluminum Brick include ordinary magnesia-aluminum bricks and magnesium-aluminum spinel bricks.
Magnesia Aluminum Brick is an alkaline refractory material fired from magnesia and a small amount of industrial alumina or alumina. The product has the characteristics of high temperature performance, high thermal shock stability, strong resistance to corrosion by alkaline substances, good wear resistance and good flexibility against high temperature heat load.
It is mainly used in the top of steelmaking open and electric furnaces, high temperature tunnel kiln, large cement rotary kiln and non-ferrous metal smelting furnace.
