| 摘 要： | 介绍一种将含钒铁水复合喷吹预脱硫、提钒过程脱硅钛及出半钢过程脱磷技术相结合形成的新型含钒铁水“三脱”预处理工艺。通过研究复合喷吹脱硫工艺的喷吹枪位、喷吹速率、脱硫剂配比等参数对脱硫的影响，优化了含钒铁水复合喷吹脱硫工艺，并在提钒过程中实现了脱硅、脱钛。通过对出半钢过程预脱磷技术研究，取得了提高脱磷氧化率、降低炼钢转炉脱磷负担的冶金效果。

| 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. |
