      Chrome corundum brick

            Chrome corundum brick The main mineral composition is alpha -Al2O3-Cr2O3 solid solution. The secondary minerals consist of a small number of refractory bricks with compound spinel (or without complex spinel) and chromium oxide content of 1% to 30%. There are two kinds of fused cast corundum bricks and sintered chrome corundum bricks. In general, chrome corundum bricks refer to sintered chrome corundum bricks.
      With alpha -Al2O3 as raw material, proper amount of chromium oxide powder and chrome corundum clinker fine powder were formed and sintered at high temperature. The chromium oxide content of sintered chromium brick is generally lower than that of fused cast corundum brick.

             Chrome corundum brick The main mineral composition is alpha -Al2O3-Cr2O3 solid solution. The secondary minerals consist of a small number of refractory bricks with compound spinel (or without complex spinel) and chromium oxide content of 1% to 30%. There are two kinds of fused cast corundum bricks and sintered chrome corundum bricks. In general, chrome corundum bricks refer to sintered chrome corundum bricks.
             Chrome corundum brick With alpha -Al2O3 as raw material, proper amount of chromium oxide powder and chrome corundum clinker fine powder were formed and sintered at high temperature. The chromium oxide content of sintered chromium brick is generally lower than that of fused cast corundum brick. It can also be prepared by mud casting method. The mixture of alpha -Al2O3 powder and chrome oxide powder is uniformly mixed, and the thickener slurry is made by adding the dissolving agent and organic binder. Meanwhile, some chrome corundum clinker is added, and the brick is made by grouting, and then sintered. It can be used as glass kiln lining, drawing glass, liquid flow hole cover brick and used for hot metal pretreatment device, garbage incinerator, coal water slurry pressurized gasifier backing.
      At present, the application of chrome corundum brick has been more widely applied. One kind of chrome corundum brick made of chromium slag is widely used in electric smelting furnace and volatile kiln. Chromium corundum brick has excellent thermal stability and high temperature creep performance, which is consistent with the requirements of the national circular economy.
      Another refractory brick, called Al Cr spinel, is widely used in copper smelting, breaking the monopoly of magnesia chrome bricks at one stroke.

      Widely used in zinc smelting electric furnace and volatile kiln, chrome corundum brick has excellent thermal stability and high temperature creep performance, and at the same time meets the requirements of the country's circular economy.
