ABSTRACT:
A method and apparatus is provided for filtering liquid-phase metal. The method comprises the steps of: (1) establishing a bath of liquid-phase metal; (2) providing a conduit connecting the bath to a filtering means; and (3) producing a magnetic field within the conduit to produce axial flow of the liquid-phase metal within the conduit to transfer at least a portion of the liquid-phase metal to the filtering means and cause at least a portion of the liquid-phase metal to flow through the filtering means.
