ABSTRACT:
A method of melting metal scrap in a molten melting media, the method comprising (a) providing a source of molten melting media in a furnace, the melting media in the furnace having a first surface level; (b) providing a first melting bay in fluid communication with the furnace to receive molten melting media from the furnace to provide a body of molten melting media in the first melting bay for purposes of melting floatable metal scrap, the first melting bay having: (i) a bottom; and (ii) an outer wall connected to the bottom defining the first melting bay, the outer wall having a generally spiral shaped cross section terminating in a mouth of a channel for removing melting media and molten scrap to an adjacent bay, the spiral shaped cross section receding away from a generally central axis of the first melting bay.
