Product Introduction
Chrome corundum brick is also known as high wear-resistant chrome corundum cast iron brick. The main mineral components are: α- Al2O3-Cr2O3 solid solution. The mineral composition of the refractory brick is a small amount of composite spinel (or does not contain composite spinel), and the chromium oxide content is 1%-30%.
There are two kinds of bricks: fused cast chrome corundum brick and sintered chrome corundum brick. Generally speaking, chrome corundum brick refers to sintered chrome corundum brick.
Chrome corundum brick is mainly used for lining of slag oil gasifier in petrochemical industry, steel wire cone of heating furnace, slide rail of steel rolling furnace, tapping platform, groove and other industrial furnaces. It can also be used for glass kiln lining, drawing glass flow hole cover brick, and backing of hot metal pretreatment device, garbage incinerator and coal water slurry pressurized gasifier.
