Magnesite brick, the content of magnesium oxide is more than *0%,periclaseas the main crystal phase of basical
refractory brick.
Magnesite with high temperature refractorness, high begining temperature of softing under loading,good alkali
resistance of slag.
According to differnence of the production technology and raw materials,it is names general magnesite brick
and fused magnesite brick.
Magnesite brick is mainly used for open hearth furnace,bottom and wall of the EAF,conventer, high temperature
tunnel
kiln,cement kiln,lime kiln, glass furnace regenerator.
