Abstract

The application of O2-CO2 mixture injection to achieve decarburization is an effective technology for reducing emissions in steelmaking. In order to reveal the non-equilibrium reaction mechanism, online mass spectrometry and 18O2-13CO2 dual isotope gases were used to analyze the decarburization process in real time. The results show that the real-time analysis method can reflect the evolution process dynamically. Although the overall decarburization rate keeps basically constant, the proportion of O2 directly producing CO2 decreases, whereas the proportion of post-combustion increases because part of the injected O2 and produced CO undergo a post-combustion reaction on the surface layer. O2 still reacts with [C] to form CO2 when the gas supply is sufficient, but when the gas supplies are critical and insufficient, the proportion of O2 reacting with [C] to form CO2 decreases to 0 and O2 only reacts to form CO during the decarburization.
