Abstract In the process of basic oxygen furnace steelmaking, high-velocity jet impacts molten metal pool, resulting in generation splashing droplets with varying particle sizes. The expansion decarburization emulsion phase is one main steel-slag reaction behaviors. this paper, firstly, a theoretical model droplet was established, finding biases their calculation results. Then, solid ratio different FeO content slag analyzed, demonstrating its significant impact on reactivity performance slag. Finally, an improved comprehensive for expanded droplets, based and data fitting, developed validated using experimental data. results indicate that decarburisation shows good agreement predicting changes carbon content, Pearson correlation coefficient exceeding 0.94 contents. ‌For contents 3%, 10%, 20%, 30%, achieves MAE (0.035%, 0.024%, 0.056%, 0.059%) RMSE (0.0034%, 0.0019%, 0.011%, 0.018%), respectively. This can accurately calculate change under various complex multiphase conditions.
