| Abstract: | 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. |
