High Temperature Refractory Magnesia Chrome Refractory Used For Cement Rotary Kiln
Magnesia Chrome Refractory
The Magnesia Chrome Refractory brick is a product made of
high-purity magnesia and imported chrome concentrate, which is made
by adding a small amount of additives and high pressure and high
temperature. Generally there are three different magnesia chrome
refractory bricks according to manufacturing method, which are:
1.Common magnesite chrome refractory 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 refractory 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 refractory brick
are made by fused magnesite chrome sinter.
CH Refractories will suggest you the most suitable and economical magnesia chrome refractory brick according to your kiln or furnace casting condition to save your money and achieve the best performance.
