ABSTRACT:
The invention disclosed herein utilizes magnetic forces to draw metal particles having magnetic characteristics into and beneath the surface of a molten metal stream flowing through a non-magnetic trough. The apparatus of the present invention includes a declined non-magnetic trough having an interior channel. Means are provided for introducing a molten metal stream into the trough. A magnetic source is provided which produces a magnetic field having flux lines which extend through the non-magnetic trough and to at least the surface of the molten metal stream. A particle discharge mechanism having contained therein substantially ferromagnetic metal particles is positioned above the surface of the molten metal stream. Gravity draws the metal particles onto the surface of the stream and the particles are drawn beneath the surface of the stream by the magnetic field.
