Product description of magnesia chrome brick
Ordinary magnesia chrome brick is made of sintered magnesia and chrome magnesia ore. Commonly referred to as magnesia chrome brick, it generally refers to magnesia chrome brick made of light burned magnesia and imported chromite ore.
Features of magnesia chrome brick
Strong erosion resistance
High softening temperature under load
High temperature volume stability is good
Details of magnesia chrome brick
Magnesia chrome brick is mainly used in cement rotary kiln, steel furnace lining, refining ladle permanent layer, non-ferrous metallurgy furnace, lime kiln, iron mixing furnace and refractory high temperature furnace lining, etc. The high temperature part of the wall of the electric furnace is made of magnesia chrome brick, the high erosion area of the refining furnace outside the furnace is made of magnesia chrome brick made of synthetic material, and the high erosion area of the non-ferrous metal melting furnace is made of magnesia chrome brick made of fused magnesia chrome brick and synthetic material. In addition, magnesia chrome brick is also used in cement kiln firing belt and glass kiln regenerator chamber.
