Abstract (en)
[origin: US2020261970A1] A device for continuously removing impurities from molten metal includes a molten metal flow path body, an inlet-side closed end plate and an outlet-side closed end plate are provided in the molten metal flow path body so as to form an impurity removal space, an electrode device composed of an inlet-side electrode and an outlet-side electrode that face each other in a longitudinal direction of the molten metal flow path body, a magnetic field device composed of a pair of permanent magnets that face each other in a width direction, sandwich the impurity removal space, and an urging device composed of the electrode device and the magnetic field device applies a Lorentz force downward to molten metal in the impurity removal space so as to increase a density of the molten metal and cause impurities in the molten metal to rise up to a surface of the molten metal.
