Abstract: The solid metal to be melted is placed on a support, within an induction coil which is adapted to provide a greater electromagnetic force towards the lower portion of the quantity of metal. When energy is provided to the coil, the metal melts from the top downward, but the concentration of electromagnetic force towards the bottom of the metal causes the liquid metal to retain a cylindrical shape. When most of the metal is melted, the liquid metal passes through an opening in the support. In a preferred embodiment, the coil is movable relative to the quantity of metal, and at the beginning of the melting process only the top portion of the quantity of metal is disposed within the coil. As the quantity of metal melts, the coil is moved downward. The method may also be used for removing impurities from the quantity of metal.

Abstract: Method and apparatus for the production of metal granules from a molten metal are disclosed. A molten metal stream is directed against an impact element located above the surface of water in a water tank. The impact of the molten metal upon the impact element causes the molten metal to disintegrate into drops which spread out radially from the impact element. The drops fall down into the water below the impact element in an annular region a certain radial distance from the impact element. The radial distance is varied by varying the velocity of the molten metal stream relative to the impact element at the instant of impact, and/or by varying the height of the impact element above the water surface, in order to substantially continuously vary the radius of the annular region in which the molten metal drops hit the water surface.By using the method and apparatus of the present invention it is possible to granulate metals and metal alloys having a low sinking rate in water and a high enthalpy.
