摘　　要：利用生产高炉冶炼参数,计算得到不同焦炭溶损反应起始温度下的高炉操作线,分析了焦炭溶损反应起始温度对高炉冶炼和技术经济指标的影响。结果表明:焦炭溶损反应起始温度对高炉操作参数有显著影响。随着焦炭溶损反应起始温度的降低,高炉还原剂消耗降低,炉顶煤气利用率提高,直接还原度降低。Base on the smelting parameters of blast furnace , the blaster furnace operating lines with different starting temperature of coke solution loss reaction were derived .The effect of staring temperature of coke solution loss reaction on smelting parameters and technical -economical index was analyzed.The results indicated that starting temperature of coke reaction was discovered to has a significant impact on carbon consumption in BF .With the increasing of initial reaction temperature , reduction agent consumption and degree of direct reduction in BF decreased and simultaneously , utilization ratio increased.
