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.
Claims20
A method for melting solid aluminum utilizing a system that comprises:
- (a) a vessel having a first chamber, a second chamber, and a raised surface;
- (b) a molten metal pump in the vessel;
- (c) a first dividing wall between the first chamber and second chamber, the first dividing wall having a first height, and an opening that is beneath the height;
- and
- (d) a second dividing wall between the second chamber and the raised surface, the second dividing wall having a second height that is less than the first height;
- wherein the method comprises the following steps:
- (e) placing solid aluminum on the raised surface;
- and
- (f) operating the pump to move molten metal through the opening in the first dividing wall, so that the molten metal exceeds the second height and flows across the raised surface until at least some of the solid aluminum is melted into melted aluminum.
