摘　　要：依据物料平衡和热平衡,计算石灰石造渣炼钢减少铁矿石/烧结矿装入对CO2排放量的影响。结果表明,用1.6kg石灰石替代1kg石灰,需少装入0.94kg铁矿石多装入0.58kg铁水,或少装入1.04kg烧结矿多装入0.54kg铁水,分别能够减少CO2排放0.89和1.1kg。Based on material balance and thermal balance in BOF,the influence of CO2 emission was calculated when using limestone for Slagging in BOF Steelmaking by decreasing addition iron ores / sinters in BOF. The results show that 1kg lime need 1. 6kg limestone replaced,which cause the BOF require decrease 0. 94 kg iron ores and add 0. 58 kg hot metals or decrease 1. 03 kg sinters and add 0. 54 kg hot metals instead,the CO2 emission of 0. 89 and 1. 1 kilogram can be reduced.
