Applications of Computational Fluid Dynamics (CFD) in iron- and steelmaking: Part 1

This review paper explores the critical role of computational fluid dynamics (CFD) in modeling iron- and steelmaking processes, which involve complex transport phenomena such as momentum, heat, and mass transfer. The objective is to evaluate how advancements in CFD over the last three decades have enhanced our understanding and operational efficiencies in these metallurgical processes. The methodology includes a comprehensive review of various applications of CFD from blast furnace operations through to continuous casting, emphasizing the evolution of modeling techniques for both single and multiphase flows. Results indicate that the integration of commercial CFD packages and increased computational power has made CFD the dominant tool for predicting dynamics in ironmaking processes. The review addresses the impact of CFD on understanding essential phenomena like three-phase reactions, melt temperature control, and the effects of fluid movements on quality and efficiency in metallurgy. In conclusion, the paper underscores the necessity of using CFD to avoid failures in metallurgical operations and drive future innovations in iron- and steelmaking processes.
