Intorduction:
Magnesite chrome bricks are 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.
Features:
1. Low bulk density, low thermal conductivity, good thermal insulation performance;
2. Refractory category allow direct contact of fire, suitable for various atmosphere;
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely;
Specifications:
Standard size (230*114*65mm) and special shape.
