摘　　要：为了分析石灰石代替石灰造渣炼钢这项技术在节能环保方面产生的效果,本文将石灰石直接进转炉造渣炼钢模式和原有的"煅烧石灰—造渣炼钢"模式的CO2排放进行详细的对比计算,结果得到用石灰石替代1kg石灰,在冷料为废钢和生铁块的情况下,分别能够减排1.29kg和1.12kg CO2。该技术为钢铁行业节能减排带来的效益巨大。In order to analyze the CO2 emissions reduction effect produced by the technology substituting limestone for lime to slag in BOF,some data of the energy consumption and CO2 emissions were calculated by comparing the mode charging limestone directly into converter for slagging with the mode calcining limestone for lime then charging lime into converter for slagging.The results showed the CO2 emissions of 1.29 and 1.12 kilogram can be reduced in the condition of 1 kilogram lime being replaced by limestone,using steel scrap and iron pig as cooling agent respectively.This technology will bring huge environmental benefits for the steel industry.
