Phase evolution simulation of A12O3-SiC-C castable with Cr2O3 addition by thermodynamic calculation
In order to make sure whether the Cr2O3 would change to Cr6+ during the service, 4wt ％ Cr2O3 was added to the calcium aluminate cement bonded Al2O3-SiC-C castables for blast furnace main trough, then the phase evolution was analyzed through thermodynamic calculation done by Factsage 6.1 ? under air atmosphere, which is close to its real work conditions. Calculations results show that Cr2O3 was reduced to Cr3C2 with low air amount, with amount of air increase, Cr3C2 transformed to Cr4C and Cr5Si3 successively, and turned to Cr2O3 at last with much more air, and no compound including Cr6+ was founded.
