Study on Final Equilibrium State and Process of CO2 Reacting with Fe-C Melt

Wenhe Wu et al.

Summary: The study found that injecting CO2 into Fe-C melt can affect the final equilibrium state of the system, with the gas able to remove or add carbon and oxygen elements. Experimental results showed that the behavior of carbon and oxygen differed from theoretical calculations at extremely low carbon content, requiring further research.

Reaction mechanism of CO/CO2 with low-carbon aluminium-killed molten steel during the ladle furnace (LF) refining process

Wenhe Wu et al.

Summary: In low-carbon aluminium-killed molten steel, the reaction mechanism of CO and CO2 depends on the concentration ratio of oxygen and carbon. If the ratio meets certain conditions, CO will dissolve in the metal phase, and CO2 will decompose into CO. Experimental results showed that increasing the aluminium content in molten steel increases the reaction rate of CO, but decreases the decomposition rate of CO2.

Effect of smelting temperature and CO2 gas flow rate on decarburization kinetics between CO2 gas and liquid Fe-C alloy

Wenhe Wu et al.

Summary: The study investigated the effects of smelting temperature and CO2 flow rate on the decarburization kinetics between CO2 and liquid Fe-C alloy. Results showed that at high carbon content, temperature had a significant impact on the decarburization rate, which increased linearly with CO2 flow rate. The establishment of a CO2 decarburization kinetics model considered various factors influencing the process, with good agreement between calculated and experimental data when the rate controlling step was identified.
