  • Patent number: 4702768
    Abstract: A process for the introduction of metal chips, especially scrap metal chips, into a molten mass of the metal of which said chips are formed, wherein the essentially dry chips are first compacted and placed into strip form, and then introduced into the molten metal bath in such strip form in an essentially continuous manner, is disclosed. A cleaning flux is also advantageously incorporated with the chips, into the compacted and strip form thereof, and then into the bath. The metal chips, after compacting and placing into strip form, are introduced directly into the molten metal bath through the skin of metal oxide existing on its surface and caused to become a part of the metal pool beneath the surface thereof without essential disturbance of the metal oxide skin except at the point of introduction.
