Finished Magnesia Chrome is mixed by high-quality chrome 
concentrate and high purity magnesite at accurate proportion. After mixing powder or briquetting and being fused at high temperature in electric furnace, Cr2O3 can be adjusted from high content to low content for different needs. Chrome Magnesia is the ideal raw material for rebonded and semi-rebonded Fused Chrome Magnesia Brick, Chrome Magnesia Ramming Mass and Tundish coating due to its high purity, large crystal size, high temperature volume stability and fine slag resistance. Its brick could be widely used in secondary refining VOD furnace, AOD furnace, RH furnace and melting furnace for nonferrous metal.
