摘　　要：This paper describes developments of high quality magnesite-chrome bricks used for secondary steelmaking furnaces,mainly including direct-bond-ed magnesite-chrome brick,fully synthesized(co-clinker) magnesite-chrome brick,semi-rebonded magnesite-chrome brick and fused grain rebonded magnesite-chroe brick,Investigations have also been conducted on the effects of various chromites on the properties of the direct bonded magnesite-chrome brick,effects of different sesquioxides (CrO3,Al3O3,Fe2O3) on the properties of the fully synthe-sized(co-clinker) magnesite-hrome brick and ef-fects of ZrO2,Cr-Fe alloy,ultra-fine powders on the properties of the fused grain rebonded brick and the semi-rebonded magnesite-chrome brick ,Applica-tions of the bricks in various secondary steelmaking furnaces have been briefly introduced as well.
