Chrome Corundum Brick Introduce
Chrome corundum brick refers to corundum refractory products containing Cr2O3, which is a refractory brick formulated with alumina powder and a certain proportion of chromium oxide, which is formed by high temperature melting. The main mineral composition is α-Al2O3-Cr2O3, which is green before burning and purple-red after burning. The bricks are not affected by H2, CO gase.
The application of more chrome corundum products, Cr2O3 content is mostly in the range of 9% ~ 15%, there are two kinds of fused chrome corundum bricks and sintered chrome corundum bricks.
According to the different chromium content, it can be divided into three types: low chromium chromium corundum, medium chromium chromium corundum, and high chromium chromium chromium corundum.
