Magnesia Chrome Refractory Brick are mainly used in metallurgical industries, such as the construction of electric furnace tops, flat furnace tops, refining furnaces and various non-ferrous metal smelting furnaces.
Magnesia Chrome Refractory Brick is mainly used for RH furnace. 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.
