Abstract

Guidelines for a cold crucible (CC) levitation melting furnace design have been examined in the literature and combined for a pilot CC concept. Meanwhile, by means of external coupling between electromagnetic and hydrodynamic problems a numerical model for liquid metal flow with free surface dynamics in an alternating EM field has been developed and verified. A 3D model with Large Eddy Simulation (LES) turbulence description is applied for a case of 1 kg of liquid titaniumlevitation in the CC furnace at two different AC frequencies. Calculation results are compared to a simplified model of the furnace section with the k-ω SST turbulence approximation.
