摘　　要：为适应连铸节奏,济钢第三炼钢厂通过优化钢铁料结构、提高转炉终点命中率、优化LF造渣及吹氩工艺、强化LF脱氧、脱硫等措施,缩短精炼周期17min,降低精炼电耗6.7kW.h/t,满足了高附加值钢种的工艺要求并实现了多炉连浇。In order to adapt the rhythm of the continuous casting, No.3 Steelmaking Plant of Jigang optimizes specific iron and steel structure, increases the percentage of goal hits of the converter, optimizes LF slag-making and argon blowing processes and intensifies LF deoxidation and desulphuration etc, shortening refining period 17min, reducing he electric consume 6.7kW.h/t. Then the process demands of high additional value steel grades are satisfied and many heats continuous casting is realized.
