The production process of chrome corundum bricks

chrome corundum brick raw material — chromium corundum brick raw material

Al₂Ó₃ is used as raw material, adding the appropriate amount of chromium oxide powder and chromium corundum clinker fine powder, after forming, and firing at high temperature. The chromium oxide content of sintered chromium corundum bricks is generally lower than that of fused cast chromium corundum bricks. It can also be prepared by slurry pouring method. Mix Al2O3 powder and chromium oxide powder evenly, add debonding agent and organic binder to make a thick slurry, add part of chromium corundum clinker simultaneously, make bricks by grouting method, and then burn.

Application of chrome corundum bricks

Chromium corundum bricks have high-temperature oxidation resistance and corrosion resistance and are used in iron and steel smelting and foundry industries, petrochemical industries, glass furnace linings, porcelain furnace linings, slag outlets slag immersion tanks, atd.
