The application of an O 2 –CO 2 mixture gas in the steel industry makes an important contribution to energy savings and emissions reduction. To clarify the reaction mechanisms of this gas mixture, isotope gases ( 18 O 2 and 13 CO 2 ) are used to study the competitive oxidation of O 2 and CO 2 , for Fe–C melts at 1873 K. Changes in gas mix composition during the decarburization of Fe–C melts with O 2 –CO 2 are monitored using an online mass spectrometer. The results show that when the O 2 /CO 2 ratio at the inlet is 4:1, the O 2 oxidation rate is approximately four times that of CO 2 . O 2 and CO 2 decarburization abilities are found to be basically the same, even when the O 2 supply is more than sufficient. As for the ability to oxidize Fe in molten steel, when the ratio of O 2 /CO 2 at the inlet is 4:1, the O 2 oxidation rate is approximately seven times that of CO 2 , allowing us to conclude that CO 2 is less able to compete with molten iron oxide.
