Chrome corundum brick
Description:
Chrome corundum brick is a corundum refractory product containing Cr2O3. Most of the chromium corundum products have 9%~15% Cr2O3. The main mineral composition is α-Al2O3-Cr2O3 solid solution, the minor mineral composition is a small amount of composite spinel (or no composite spinel), and the content of chromium oxide is 1%~30%.
Advantage:
Excellent resistance to thermal shock, excellent high temperature creep
Application:
Petrochemical industry, electric furnace for zinc smelting, copper smelting furnace, garbage incinerator
