“…Recently, the reduction of CO2 emissions in the iron and steel industry has mainly involved three aspects: the upgrading of existing mature energy-saving technologies, the development and industrialization of key energy-saving technologies and the development and application of cutting-edge technologies [7,8] . Extensive studies on carbon emissions in the iron and steel industry have been conducted, mainly focusing on the use of CCS [9][10][11][12] , CCU [13][14][15][16] , and CCUS [17][18][19][20] to reduce carbon emissions. CCS technology includes three parts: carbon dioxide collection / capture, transportation, and storage, which focuses on storage after capture.…”

CO2 has characteristic properties and reactions at converter smelting temperature, and the chemical reaction between CO2 and elements such as C and Si in the molten pool has bubble proliferation and cooling effects, which can effectively improve the kinetic and thermodynamic conditions of converter smelting. Here, an experimental study and industrial test on the application of CO2 in converter smelting were carried out. The smelting effects of Mode-1 and Mode-2 with total CO2 injection amounts of 229 Nm3 and 196 Nm3, respectively, were compared, and the changes in molten steel and slag compositions, dust removal, and gas are analyzed. The test results show that converter top and bottom blowing CO2 technology (COMI-B)technology had significant metallurgical advantages over the N-Mode; the dephosphorization rate increased by 4.2%, slag (FeO) content was reduced by 2.04%, end point nitrogen content of molten steel was reduced by 20%, gas recovery increased by 8.29 Nm3/t, and soot production reduced by 14.7%. The results of the study provide reference for the application of COMI-B technology in converters in the iron and steel industry and develop a new path for resource utilization of CO2.
