主　　题：CO2 utilization carbon dioxide steelmaking enhanced stirring temperature control 

摘      要：In last decade,the utilization of CO?resources in steelmaking has achieved certain metallurgical effects and the technology is *** this review,we summarized the basic reaction theory of CO2,the CO2 conversion,and the change of energy-consumption when CO2 was introduced in converter steelmaking *** the CO2-O2 mixed injection(COMI)process,the CO2 conversion ratio can be obtained as high as 80%or more with a control of the CO2 ratio in mixture gas and the flow rate of CO2,and the energy is saving and even the energy consumption can be reduced by 145.65 MJ/t under certain *** addition,a complete route of CO2 disposal technology is proposed combining the comparatively mature technologies of CO2 capture,CO2 compression,and liquid CO2 storage to improve the technology of CO2 *** results are expected to form a large-scale,highly efficient,and valuable method to dispose of CO2.
