Product introduction of chrome corundum brick
Chrome corundum brick is also called high wear-resistant chrome corundum tapping brick. with α- Al2O3 is the raw material, added with appropriate amount of chromium powder and chrome corundum clinker fine powder, shaped and fired at high temperature.
Chromium corundum bricks are mainly used for the lining of the residue gasification furnace in petrochemical industry, the molten steel tap of the heating furnace, the slide rail and tapping platform of the steel rolling furnace, and the groove and other industrial furnaces. It can be used as the lining of glass furnace, brushed glass flow hole cover plate brick, and as the back lining of thermal metal pretreatment device, garbage incinerator, coal water slurry pressurized gasifier.
