MAGNESIA CHROME BRICK PROFESSIONAL MANUFACTURER

Magnesite chrome description

Magnesite chrome brick is mainly composed of magnesium oxide and chromium trioxide, crystalline phase are calcite and spinel. Magnesite brick with the characters of high temperature of refractories, high temperature of strength, Strong resistance to alkaline slag erosion,Good thermal stability and adaptability to acid slag,The main raw materials for making magnesite chrome brick are sintered magnesium-sand and chromite. The raw material purity of magnesia sand should be as high as possible. The chemical composition of chromite is Cr2O3, the content requirement is 30-45%, and CaO is 1-3.0%.

Magnesite chrome brick types
Magnesite chrome brick is divided into sintered magnesite chrome brick and non-sintered magnesite chrome brick, sintered magnesite chrome brick is divided into genera magnesite chrome brick and direct rebonded magnesite-chrome brick, semi-rebonded magnesite chrome brick and electro fused rebonded magnesite chrome brick.
In addition, there are also fused cast magnesite chrome bricks which directly poured with the fused magnesia-chrome material through the electric arc furnace.

Magnesite chrome applications
