ALUMINUM SCRAP MELTING PROCESS AND SYSTEM

摘要

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 (2), the melting media in the furnace (2) having a first surface level; (b) providing a first melting bay (6, 40) in fluid communication with the furnace (2) 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 (28); and (ii) an outer wall (42) connected to the bottom defining the first melting bay, the outer wall having a generally spiral shaped cross section terminating in a mouth (60) of a channel (58) for removing melting media and molten scrap (30) to an adjacent bay (12, 56), the spiral shaped cross section receding away from a generally central axis of the first melting bay.
