The refractory 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.
