Abstract：A hot metal tride pretreatment process combined with complex blowing predesulfurization for vanadium bearing hot metal，desilicon and detitanium during extracting vanadium，dephosphorization with dumping semi- steel was proposed. The complex blowing predesulfurization process was optimized by studying parameters of lance，blowing rate and desulfurizer ratio，and desilicon and detitanium in the Vanadium extraction process were realized. This study improved the oxidation rate and reduced the burden of converter through the dephosphorization technology research of semi- steel.
