Product Introduction

Direct combination of magnesia chrome brick using high purity magnesia and chrome concentrate as the main raw material, add special magnesia chrome composite pointed stone, by high pressure molding, high temperature sintering. The product has less impurities, the glass phase is concentrated in the triangular area of the product body, and the crystal phase is directly combined with the product phase. It has the characteristics of low porosity, high compressive strength, wear resistance, corrosion resistance and peeling resistance. In 2009, it won the national invention patent (patent number ZL 200710189924.0). The product is mainly used in anode furnace, flash furnace, reverberatory furnace, side blowing furnace, converter and other non-ferrous smelting furnace non-harsh parts.
