ABSTRACT:
This invention relates to a method and a system including apparatus for submerging, entraining, melting and circulating aluminum scrap in a molten metal media, which scrap is comprised of pieces not capable of self-submergence. The apparatus of the system includes means to introduce a supply of scrap into an open bay that has heated molten metal drawn from an entry point below the surface of the molten metal by the action of a molten metal scrap entrainment circulator submerged beneath the surface of the molten metal at a point beneath the entry point of the heated molten metal. The circulator continuously draws the heated molten metal including the scrap into the circulator wherein the scrap is completely entrained in the molten metal and delivered into a molten metal circulation path that delivers the scrap metal entrained in the molten metal for subsequent heating further melting and recirculation to the circulator.
