| Abstract Scope |
Secondary aluminum production relies on effective melt treatment to remove impurities, optimization is limited by the availability of controlled and industrially relevant pilot-scale platforms. To address this limitation, a modular Liquid Metal Loop (LML) was constructed at NTNU to enable systematic investigations of melt treatment technologies under representative operating conditions. A permanent magnet pump (PMP) was used to achieve contactless circulation of liquid aluminum via the Lorentz force interaction.
Initial benchmarking focused on melt thermal stability and the relationship between flow rate and PMP operating parameters. Flow rates were determined using pressure drop correlations across orifice dams and showed a linear dependence on pump settings, consistent with predictions from solid-billet characterization. These findings were independently supported by compositional analysis of nickel silicide and yttrium oxide tracer particles. Thermocouple measurements indicated limited thermal gradients, with temperature differences below 5 °C between heated and unheated sections, demonstrating stable, well-controlled loop operation. |
