Electroslag remelting (ESR) is an extensively used process to produce metallic ingots with high quality standards. In order to investigate the possibly important impact of the behavior of liquid metal droplets in the slag on the solidification of the ingot, DNS and engineering modeling have been associated. At MU Leoben, several 3D simulations were performed to explore the effects of the electric current and electrode immersion depth on the dripping phenomena. Simultaneously a 2D multiphase model was used to estimate the distribution, speed, and overheat of the droplets entering the liquid pool. With adequate adaptations, the results given by this computationally cheap 2D model can fit the 3D results. The aforementioned results are then used to improve a 2D engineering model previously developed at IJL Nancy, aimed to help optimizing the operation parameters. For validation, several remelting experiments at industrial scale were performed under various geometrical and electrical conditions.
