The EAF steelmaking process is a complex, high-temperature physico-chemical process in which gas, solid, liquid, and arc plasma coexist, and momentum, mass and heat transfer are coupled. Attempts to concurrently capture all of the complex physical phenomena through traditional simulation are difficult, time-consuming and prone to divergence. In this study, a comprehensive computational fluid dynamics (CFD) model was developed for a full-scale industrial EAF. A new integration approach was proposed in this study based on the momentum transfer between the jet and the molten bath. In-bath decarburization characteristics were investigated.
