Detailed Description

Magnesium Chromium brick Magnesite chrome fire brick to magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient,periclase and spinel as main mineral components of refractory products.Common Magnesite chrome fire brick is made by sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate. 1.Common Magnesite chrome fire 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.Refractory brick 3.Semi-rebonded and Fuse-rebonded magnesite chrome brick are made by fused magnesite chrome sinter.
