ABSTRACT:
In a charge well for adding scrap metal pieces or particles to a molten metal bath, a stationary diverter is provided within a charge well for diverting the circular flow of molten metal, caused by the orientation of the inlet port, in a downward direction, thereby creating a downward flow of molten metal which results in quick and efficient submergence of incoming lightweight scrap metal pieces or particles. Preferably, the diverter includes a leading edge which extends in a generally radial direction within the charge well and a flat top surface which tapers from the leading edge to a point or narrowed trailing edge. A downward curved surface extends from the leading edge to facilitate the downward flow of molten metal. The diverter may be mounted on a support member extending above the charge well.
