High purity Magnesia chrome brick Mag Chrome refractory brick for landle
Magnesite chrome brick to magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient,periclase and spinel as main mineral components of refractory products. 1.Common Magnesite chrome brick is made by sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate. 2.Direct-bonded Magnesite chrome brick is made by chrome ore with low content of impurities and pure magnesite,firing at the temperature above 1700°C. 3.Semi-rebonded and Fuse-rebonded magnesite chrome brick are made by fused magnesite chrome sinter.

Made of high purity magnesia and chrome concentrate, it is produced by high temperature firing, with properties of excellent thermal shock stability, slag attack resistance, thermal fatigues resistance, and vacuum damage resistance. In addition, they are resistant to oxidation reduction, comparatively better wear resistance and erosion resistance.
