1. In combination with a furnace for maintaining metal that is within it in a molten condition as a melt, and further having a charging well which opens upwardly and contains a portion of the melt, so that the melt is exposed in the charging well, the improvement comprising:

  • a track located generally above the charging well as well as beyond the charging well and a vortex generator suspended from the track, the vortex generator including a trolley which rolls along the track, an elevator suspended from the trolley, an impeller suspended from the elevator and being exposed generally below the elevator, drive means for rotating the impeller, and elevating means for varying the distance between the trolley and the elevator to lower the impeller into the melt within the well, so that it creates a vortex within the portion of the melt that is in the well, and to further raise the impeller out of the well to an elevation high enough to permit the vortex generator to be displaced on the track to a position remote from the well.
