050 Comprehensive Model of Oxygen Steelmaking Part 2 Application of Bloated Droplet Theory for Decarburization in Emuls

This paper presents a comprehensive model for oxygen steelmaking focusing specifically on the decarburization reaction in the emulsion zone by incorporating the bloated droplet theory, building upon the findings of Part 1. The objective is to enhance the understanding of the kinetics involved in the decarburization process under practical industrial conditions. Utilizing a computer-based model, the study evaluates the factors that influence decarburization rates in the emulsion phase through analytical methods and industrial data validation. Results indicate that the decarburization rates can reach up to 60% of the total rate during the primary blow, with significant variations in residence time observed, ranging from 0.4 to 45 seconds for metal droplets. The findings underscore that droplet size and ejection angle critically affect the decarburization rates; smaller droplet sizes and more direct ejection angles correspond to increased decarburization efficiency. This research provides practical insights that can potentially improve the operational control of the oxygen steelmaking process, ultimately enhancing productivity and efficiency in industrial applications.
