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.
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.
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.

CH Refractories manufactured casting powder is widely applied for both opening and protected CCM casting condition as well as molded casting . Our engineer will design each order of casting powder composition according to steel grade, casting speed, and other related casting condition.
Low cement refractory castable made by CH Refractories with three levels, which are high aluminum low cement castable, mullite low cement castable and corundum low cement castable.
The EAF refractory gunning mix uses high quality magnesia as the main materials, by adding compound binding additives, the series of gunning mixes for EAF refractory repairs feature high adhesive strength, low rebound rate, good sintering, good erosion resistance, and can be used as cold or hot refractory repairs materials at slag line and side wall.
