Mag Chrome Brick is mainly used in metallurgical industry, such as for building open-hearth furnace top, electric furnace top, finery out of furnace and all kinds of non-ferrous metal metallurgy furnace. Fused cast magnesite chrome brick is adopted for high temperature position of furnace wall in electric furnace with ultra high power.
Magnesia chrome brick that made of synthetic compost is adopted for strong erosion area in finery out of furnace. Fused cast magnesite chrome brick or magnesia chrome brick that
made of synthetic compost is adopted for strong erosion area of non ferrous metals flash smelting furnace. Besides, Magnesia Chrome Brick also can be used for burning zone in
rotary cement kiln and regenerative chamber in glass furnace.
