| Abstract: | Under the special hot metal condition in ChengSteel (wV=0.15%-0.25%, temperature of molten iron at 1280-1380℃) and theoretical analysis, the qualified vanadium slag and semi-steel were obtained by taking N2-O2 vanadium extraction mode which controlled the parameters of vanadium extraction by converter processes. The production practice indicated that the low-vanadium extraction from high temperature molten iron was achieved and good economic benefits were realized. |
