Abstract: In this work, large-scale electromagnetic levitation melting of metals in two-frequency horizontal fields is investigated. A coupled electromagnetic field and free surface flow problems are solved with a three-dimensional model that incorporates a Large Eddy Simulation turbulence description. The developed numerical model is used to design a pilot furnace for stable levitation melting of Al and Ti-6Al-4V samples up to 500 g. The new FastCast concept that utilizes the novel crucibleless levitation melting method for industrial mass production of single-shot castings (e.g., Ti-6Al-4V turbocharger impellers up to 500 g) is introduced.
