Abstract

1. Process for feeding discrete metal particles into a flowing metal melt, especially for melting metal scrap or waste metal granules, characterised in that the metal melt is divided up into two component streams, each component stream is set into a rotating movement about its direction of flow whereby two melt rolls rotating in opposite directions to one another are produced, in that the two melt rolls are conducted together, an angle of their directions of flow being formed, and generate in the region where they meet a furrow drawing in the discrete metal particles, the metal particles being added at this position.
