Product description
The refractory mag chrome 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 mag chrome brick according to manufacturing method, which are:
1.Common mag 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 mag 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 mag chrome brick are made by fused magnesite chrome sinter.
Application of mag chrome brick:
Mag chrome brick mainly used in cement rotary kiln, glass kiln regenerator chamber, steelmaking furnace lining, refining ladle permanent layer, non-ferrous metallurgy furnace, lime kiln, mixing furnace and refractory high temperature kiln lining.
