摘　　要：为降低炼钢工序成本,实现转炉渣料成本最优,进行了转炉低成本造渣技术的研究与试验。以"留渣+双渣"为基础冶炼模式,确定了石灰石、铁矿石在转炉少渣冶炼中的使用方案,使石灰消耗由42.4 kg/t降低至26.5kg/t,铁矿石用量由0 kg/t增加至23.5 kg/t,转炉渣料成本降低4.8元/吨钢,金属料成本降低7.05元/吨钢。To reduce the cost of steel making process,achieving optimum cost of slag formation of converter,the research and experiment of low cost slag-making technology of converter are carried out.On the basis of the"leave a residue+double slag basic smelting mode,determine the limestone,dolomite,iron ore use plan in converter smelting with less slag,make the lime consumption reduced from 42.4 kg/t to 26.5 kg/t,iron ore consumption increased from 0 kg/t to 23.5 kg/t,slag material cost down 4.8 yuan/ton,metal material cost down 7.05 yuan/ton.
