Magnesia chrome bricks are mainly used in metallurgical industries, such as the construction of flat furnace tops, electric furnace tops, refining furnaces and various non-ferrous metal smelting furnaces.
The refractory product for RH furnace is mainly magnesia chrome brick. The fused magnesia chrome sand and chrome ore with high content of Cr2O3 and high purity are the main raw materials. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag corrosion, excellent thermal shock resistance and certain adaptability to acidic slag.
