Product Features:

The brick made from sintered magnesia clinkers and chrome ore,sintering at high temperature 1600°C is named sintered magnesia-chrome brick. It is usually called magnesia-chrome brick. The refractory, contains MgO 50-70%,Cr2O3 8-16%. It has good specifications in stability, high temperature constructure strength,resistance to basic slags, resistance to acid (better than magnesite brick) and refractoriness 2000°C .The brick is extensively applicated innonferrous furnane,steel electric arc, steel open hearh, converters, torpedo, vacuum treatment unit,burning zone of cement rotary kiln, thermal storage comber of glass kiln.
