摘　　要：结合现有生产态势,介绍了在高铁耗模式和低铁耗模式两种不同的生产条件下,第一炼钢厂炼钢车间对石灰消耗的不同控制方法。现阶段低铁耗生产模式下,对造渣料组分和吹炼工艺进行优化后,转炉阶段的石灰消耗已经控制到46.6 kg/t,为后续进一步降低石灰消耗打下坚实的基础。Based on the current production situation,this paper introduces the different methods to control the lime consumption under both high and low iron consumption modes in the steel-making workshop of Steel-making Plant 1#.By optimizing the slag composition and the blowing process under the low iron consumption mode,the lime consumption of converter process is reduced to 46.6 kg/t,laying a solid foundation for further reducing the lime consumption in the future.

关 键 词：石灰消耗 转炉炼钢 低铁耗模式
