Abstract: A system and method for filling a mold with molten aluminum includes a molten metal pump, a vessel configured to contain molten metal, a mold for receiving molten metal, and a conduit between the vessel and the mold. Molten metal is pumped in the vessel until it reaches a level at which it flows through the conduit and into the mold. The flow of molten metal into the mold is stabilized to maintain a level of molten metal in the mold. A skin of solid metal forms between the mold and the conduit, at which time the pumping of molten metal can cease. The mold with solid metal in it can be moved.

Abstract: A vortex metal insertion system for a metal recycling furnace, the system
having a molten metal flow cycling through the furnace and through a vortex bowl in the system. The system includes one or more process sensors in the furnace, an automated molten metal flow adjustment device, and a computer controller. The computer controller reads the sensor(s) and adjusts the adjustment device to control the flow of molten metal through the vortex bowl based on the reading(s). The system has an insertion port through which scrap metal and other materials may be controllably inserted into the molten metal flow.

Abstract: A scrap melting system and method includes a vessel that is configured to retain molten metal and a raised surface about the level of molten metal in the vessel. Solid metal is placed on the raised surface and molten metal from the vessel is moved upward from the vessel and across the raised surface to melt at least some of the solid metal. The molten metal is preferably raised from the vessel to the raised surface by a molten metal pumping device or system. The molten metal moves from the raised surface and into a vessel or launder.

Abstract: An exemplary furnace system for melting stock metal includes a main hearth and a side well subsystem, which includes a melting well disposed downstream of the main hearth for receiving flow from the main hearth, an input flow inducer disposed upstream of the melting well and downstream of the main hearth, and an output flow inducer disposed downstream of the melting well and upstream of the main hearth. The input flow inducer drives molten metal into the melting well, thereby forming a differential metal head in the melting well. The output flow inducer evacuates molten metal from an output conduit, thereby reducing counter-pressure at an output port of the melting well communicating with the output conduit. This allows atmospheric pressure to add to the differential metal head in the melting well, resulting in an increase in productivity of the side well subsystem and of the furnace system as a whole.
