Electromagnetic Levitation Melting

In this paper a new drip-and leakage-free method for the electromagnetic levitation melting of metallic samples with greater weights, stabilized position and free surface shape is presented. The method can be used in a melting furnace, as well as for the coreless induction valves applied for the flow rate control, e.g. in the continuous casting of molten metals.The applicability of the method was examined numerically and experimentally proved by tests conducted with different types of laboratory setups.

AbstractIn this paper, the velocity field and turbulence effects that occur inside a crucible of a typical induction furnace were investigated. In the first part of this work, a free surface shape of the liquid metal was measured in a ceramic crucible. Then a numerical model of aluminium melting process was developed. It took into account coupling of electromagnetic and thermofluid fields that was performed using commercial codes. In the next step, the sensitivity analysis of turbulence modelling in the liquid domain was performed. The obtained numerical results were compared with the measurement data. The performed analysis can be treated as a preliminary approach for more complex mathematical modelling for the melting process optimisation in crucible induction furnaces of different types.
