      Chrome Brick

      Chrome brick is a kind of refractory product made from Chrome ore with content of Cr2O3 ≥ 30%.  High chrome bricks are mainly applied in the key parts of the furnaces in coal chemical industry, chemical industry, alkali-free glass fiber and garbage incinerator, etc.

      Description of Chrome Brick:

       

      Chrome brick is a kind of refractory product made from Chrome ore with content of Cr2O3 ≥ 30%. In order to improve its high temperature performance, it usually adds more than 10% of magnesia.

       

      Chrome brick is neutral refractory brick with very weak effect to acidic and basic refractories at high temperatures. The load softening temperature and thermal shock resistance of Chrome Brick are lower than that of magnesia-chrome brick. Chrome Brick is mainly used for high temperature acidic and alkaline refractory barrier layer, but also for non-ferrous smelting furnace lining. But Chrome Brick is not suitable used for direct contact with the molten iron and at frequently changeable temperatures.

      High chrome bricks are mainly applied in the key parts of the furnaces in coal chemical industry, chemical industry, alkali-free glass fiber and garbage incinerator, etc. Chromium corundum bricks are mainly used for the lining of carbon black furnace and copper smelting furnace, Glass furnace molten bath, tapping platform of rolling mill furnace. Chrome corundum also can be used as upper structure and burner bricks for insulating fiber glass furnace.
