In the conventional steelmaking process, dust generation poses a significant challenge, resulting in reduced recovery rates of metal and increased energy consumption. The primary objective of this study is to investigate the effects of a stepped carbon dioxide (CO2) blowing rate on dust generation during the Basic Oxygen Furnace (BOF) process, contributing to greener steel production methods. Employing a combination of thermodynamic analysis and experimental measurements at Fujian Sanming Iron and Steel Plant, the research explores the novel CO2 and O2 Mixed Blowing steelmaking process (COMB). The results demonstrate that the stepped CO2 blowing rate substantially reduces the average dust generation rate by 12.5% compared to traditional methods, alongside a 12.7% decrease in the total iron (T-Fe) content within the dust. This study highlights the potential of CO2 application in dust management during BOF operations, promoting energy-saving solutions and emission reductions while addressing the growing environmental demands of the steel industry.
