Fused chrome corundum brick main mineral composition

 

Fused chrome corundum brick:

The main mineral composition of chrome corundum is α-Al2O3-Cr2O3 solid solution.

Secondary mineral composition of a small amount of composite spinel (or without composite spinel), chromium oxide content of 1% to 30% of the refractory bricks.

There are two kinds of cast chrome corundum brick and sintered chrome corundum brick.

In general, chrome corundum brick refers to sintered chrome corundum brick. Α-Al2O3 as raw material, adding appropriate amount of chromium oxide powder and chrome corundum clinker powder, by molding, firing at high temperatures. Sintered chrome brick is generally lower than the chrome chrome brick. Can also be prepared by slurry casting method, the α-Al2O3 powder and chromium oxide powder evenly mixed with gelants and organic binder made of thick mud, while adding part of the chrome corundum clinker, made of grouting brick, And then burned. Can be used as glass kiln lining, drawing glass flow hole cover tiles and for the hot metal pretreatment device, waste incinerator, coal slurry pressurized gasifier lining and so on.
