This study focuses on the development of a comprehensive model for the decarburization process in the impact zone of oxygen steelmaking. The objective is to evaluate key process variables affecting decarburization kinetics by utilizing a semi-empirical approach based on experimental data. Methodologically, the model integrates diffusion through gas and surface control mechanisms to calculate decarburization rates, and it is validated against experimental and plant data. The results demonstrate that the model is consistent with observed data, effectively predicting that about 40% of the decarburization occurs within the impact zone during the main blow. Notably, the predicted decarburization rate shows sensitivity to variations in partial pressures of carbon dioxide and oxygen. Specifically, it indicates a decrease in reaction rate from 202 kg/min to 134 kg/min as the partial pressure of oxygen decreases from 26.4 to 16.2 kPa. This underscores the relevance of optimizing gas concentrations to enhance carbon removal efficiency in the steelmaking process.
