摘　　要：通过对提钒转炉出钢前期以及后期的挡渣技术工艺进行尝试,并且对挡渣成功率、下渣量、经济效益等方面进行综合考虑,最终选择了挡渣球挡渣法。最后通过优化挡渣球结构和加入挡渣球的方式,降低了出钢过程中的钒渣流失率、提高了钒渣产量和钒回收率,使挡渣成功率提高到约90.32%,出钢平均下渣量减少到42 mm,取得了很好的经济效益。Through the trial of slag stopping technology before and after steel tapping of the vanadium extraction converter,under the comprehensive consideration of the success rate of slag,slag quantity and economic benefit,the slag stopping method is finally chosen.Finally,by optimizing the way of the slag ball structure and slag retaining ball,the turnover rate of vanadium slag is reduced,vanadium slag yield and recovery rate of vanadium are increased,and the success rate of the slag is increased to about 90.32%.The average slag amount of steel tapping is reduced to 42 mm,which makes good economic benefit.
