Magnesia Chrome Refractory Bricks Intorduction
Magnesite chrome bricks are refractory products with magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components.
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 chromite brick Feature:
1.High refractoriness2000,
2.excellent anti-oxidation,
3.high strength
4.perfect thermal Stability;
5.Low bulk density, low thermal conductivity, good thermal insulation performance.
6.Refractory category allow direct contact of fire, suitable ofr various atmosphere
7.Good integrity with furnace lining, long service life, easy operation, could be shaped freely
8.Product specification: standard form, normal standard, shaped and special shaped bricks.
