A non-ferrous metal melting furnace includes a non-ferrous metal melt pump (1), a vortex chamber body (2), and a magnetic field device formed of permanent magnets. The vortex chamber body (2) makes a non-ferrous metal melt flow into a vortex chamber (6) from an inlet (5) in a spiral shape by applying a driving force to the non-ferrous metal melt (M) melt in the vortex chamber (6), and discharges the non-ferrous metal (M) melt from the vortex chamber (6) to an outlet (7). The magnetic field device formed of permanent magnets is disposed outside the vortex chamber (6) and below a bottom plate of the vortex chamber, (6), and applies the driving force to the non-ferrous metal melt by an electromagnetic force that is generated by current flowing in the non-ferrous metal (M) melt and magnetic lines of force from the magnetic field device formed of permanent magnets (56, 56). |
