摘　　要：热装铁水替代部分废钢,是目前电炉炼钢的发展趋势,既减少了钢液中的有害元素含量,也为降低炼钢成本、提高电炉生产率打下了基础。通过对实际生产中冶炼数据的分析,总结出了不同热装铁水比例对CONCAST110t超高功率电弧炉冶炼工艺的影响效果,并确定了合理的热装铁水比例。为优化电炉冶炼模式,提高钢水质量及降低消耗提供了参考。分析认为,选择30%～50%的热装铁水比例,对于CONCAST110t电炉而言,综合消耗较为理想。It is a development trend for contemporary EAF steel-making that hot molten iron substitutes partial scrap,which reduces detrimental element content in steel and lays a foundation for lowering production cost and improving productivity.Through analysis on smelting data in actual production,the authors summarize the influential effect of different molten iron hot charging ratios on Concast 110t ultra high power EAF smelting process and determine a reasonable ratio,which provides a reference for optimizing EAF smelting mode,improving steel quality and reducing consumption.By analysis,the authors deem that the overall consumption of Concast 110 t EAF is ideal with 30% ~ 50% molten iron hot charging ratio.
