Description of Magnesite Brick
Magnesite Brick for Cement and Glass Plant are designed and manufactured as per the different usage parts and working conditions of electric furnace, converter and ladle. Magnesite Brick is shaped by high purity & high compact or large crystalline fused magnesia and high purity graphite as main materials and phenolic resin as binder.
Magnesite Brick is mainly applied for the lining parts of electric furnace and converter. Directly touching molten steel and slag, Magnesite Brick has the advantages of high strength, high slag resistance, good thermal stability and high refractoriness.
