Magnesite chrome brick with magnesium oxide (MgO style) and three oxidation 2 chromium Cr2O3) as the main ingredients (, FangMei stone and spinel as the main mineral components of the refractory products. This kind of brick high refractoriness, high temperature strength, strong resistance to basic slag erosion resistance and good thermal stability of acid slag, also have certain adaptability. Manufacturing magnesite chrome brick of main raw material is sintered magnesite and chromite. The purity of raw materials to be as magnesite high chemical composition of the bed, but the requirements as the: Cr2O330 ~ 45%, CaO is not more than 1.0 ~ 1.5%.

Application field

Magnesite chrome brick is mainly used in metallurgy industry, such as steel mill building electric stove top, outside the furnace stove top, and all kinds of finer melting furnace of non-ferrous metal. High power electric stove wall of high temperature parts adopt mg-chrome bricks casting, outside the furnace high erosion area to use synthetic finer material made of brick, magnesite chrome non-ferrous metal flash melt furnaces area USES high erosion profiles of mg-chrome bricks, synthetic material made of mg-chrome bricks. In addition, magnesite chrome brick is used in cement rotary kiln firing belt and glass kiln of regenerator and other parts.
