Material and Technique: made from high purity and density magnesia and sintered magnesia dolomite clinker with major components of percales and lime. The brick is shaped under high pressure and fired with high temperature, with appropriate Mgo/Cao ratio to meet with the requirement of various applications.
Properties: good thermal shock resistance and anti-spelling performance, purifying the steel by removing sulfur and phosphorus, providing good coating protection to the kilns when used in cement rotary kilns.
Application: applied mainly in stainless refining furnaces such as AOD, VOD, and ladles, widely applied in the burning zone of cement kilns as the replacement of magnesia chrome brick.
