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.
Magnesia chrome bricks are mainly used in cement rotary kilns, glass kiln regenerators, steelmaking furnace linings, refining steel cladding, non-ferrous metallurgy furnaces, lime kilns, iron mixers and refractory high-temperature furnace linings.
