Abstract: In this paper, a drip- and leakage-free approach for electromagnetic (EM) levitation melting of metallic samples in horizontal and orthogonal two-frequency fields is studied further. Numerical simulation is used to design an experimental furnace for a stable levitation melting of aluminum samples with increased weight. The scale-up of the method is validated by experiments with aluminum (Al) samples up to 0.5 kg.
