Chrome Magnesite Bricks
The Chrome Magnesite Bricks 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.
