Product description
Magnesia chrome refractory brick is a refractory product with MgO and Cr2O3 as the main components, and cubic magnesite and spinel as the main mineral components. The main raw materials for the manufacture of magnesia chrome bricks are sintered magnesia and chromite, the purity of magnesia raw materials should be as high as possible, the chemical composition of chromite requirements are: Cr2O3:30 ~ 45%, CaO: ≤1.0 ~ 1.5%
The refractoriness is greater than 2000 ° C, the load softening temperature is generally above 1550 ° C, the high temperature volume stability is good, and the resistance to acute cold and acute heat is good.
Application of magnesia chrome refractory brick:
Mag chrome brick mainly used in cement rotary kiln, glass kiln regenerator chamber, steelmaking furnace lining, refining ladle permanent layer, non-ferrous metallurgy furnace, lime kiln, mixing furnace and refractory high temperature kiln lining.
