Abstract
Disclosed is a system for remelting light gauge scrap metals which includes a remelting furnace with separate heating and melting chambers and pump means for inducing circulation of molten metal between the two. Also included are auger means adapted to include light gauge "floating" scrap metal from the melt into the central zone of the melt.
Claims13
A system for remelting light gauge scrap metals comprising:
- a. remelting furnace means separated into at least one heating and at least one melting chamber;
- b. heating means associated with and operable on each of said at least one heating chambers but separated from each of said at least one melting chambers;
- c. port means located to enable the flow of molten metal between each of said at least one heating chambers and at least one of said at least one melting chambers and positioned to be below the surface level of molten metal within remelting furnace means;
- d. molten metal pumping means operable to produce a flow of molten metal and positioned to direct said flow of molten metal from each of said at least one heating chambers into at least one of said at least one melting chambers and from each of said at least one melting chambers into at least one of said at least one heating chambers through said port means;
- and
- e. auger means, separate from said molten metal pumping means, located within each of said at least one melting chambers, positioned below and adjacent to said surface level to produce a gravity flow of said surface level of said molten metal thereto and downwardly therethrough, and operable to mechanically force light gauge scrap metals, which are located adjacent to said surface level of said molten metal, downwardly and substantially beneath said surface level of said molten metal concurrent with said gravity flow of said surface level of said molten metal.
