Fuse-rebonded Magnesia-chrome Brick
1.Fuse-rebonded magnesia-chrome brick are made by high grade fused magnesite chrome clinker as raw material and rebonded by super high temperature.
2.High strength,erosion resistance,high temperature resistance and good slag resistance.
3.Severe environment such as steel making EAF,converter,AOD,VOD,RH,DH, SKF refining ladle etc.
