Magnesia Aluminum Brick alkaline refractory material for industrial
furnace include ordinary magnesia-aluminum bricks and magnesium-aluminum
spinel bricks.
Magnesia Aluminum Brick alkaline refractory material for industrial
furnace 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.
Magnesia Aluminum Brick alkaline refractory material for industrial
furnace 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.
