摘　　要：通过对电弧炉底吹搅拌工艺技术原理的研究,分析了电弧炉底吹搅拌工艺对炼钢冶金过程的影响,进而制定了合理可行的底吹工艺参数。在通钢第一炼钢厂在70tConsteel电弧炉上安装了电弧炉底吹搅拌系统,冶炼结果表明:电弧炉底吹工艺能有效加强熔池搅拌强度,从而提高电弧炉熔池脱碳速度、脱磷率,降低终渣FeO含量,降低氧气消耗,缩短熔炼周期,为电弧炉高效冶炼提供帮助;冶炼成本分析表明,电弧炉底吹搅拌能有效降低冶炼成本,为电弧炉高效化炼钢提供了廉价而有效的途径。By study of principles of bottom blowing stirring in EAF, the paper analysed the influence from EAF steelmaking bottom blowing stirring process to metallurgical process and formulated the feasible. In the first steel making factory in TONGHUA steel company, EAF bottom blowing stirring system was installed in the 70 tons＇ s Consteel Furnace. The result showed： EAF blowing stirring technology could effectively strengthen the stirring intensity of molten pool, and then improve the molten pool decarbonization speed, dephosphorization rates, reduce the content of FeO in end slag, oxygen consumption, shorten the tap to tap time, and provide efficient help for EAF melting. Smelting cost analysis indicated that EAF bottom blowing stirring process could effectively i＇educe the smelting cost, provide cheap and effective solutions for the EAF high-effectiveness steel making.
