Product Description
Magnesia Chrome Brick Information
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 Brick Features
1. Low bulk density, low thermal conductivity, good thermal
insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr
various atmosphere
3. Good integrity with furnace lining, long service life, easy
operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped
and special shaped bricks.
China magnesite chrome refractory bricks for industrial furnace
Standard sizing: 230 x 114 x 65 mm ,Special size and OEM Service
also provide!
The size is precise, providing kinds of shapes according to
customer's drawing
