<p>A metal handling system for delivering molten metals, such as magnesium and its alloys, to a continuous casting machine (11) without exposure of the molten metal (13) to the ambient atmosphere and at reproducible pressures and quantities. The metal (13) is conveyed from a crucible, melting pot or an electrochemical cell (10) to a casting machine (11), e.g. a die caster, strip caster, sand mold, and the like. The elements for conveying the molten metal (13) include a magneto-hydrodynamic pump (12) and heated conduits (14) to carry the molten metal (13) to the casting machine (11). Preferred features of the handling system include a flowmeter (15) and a shot size delivery mechanism (16). Optionally, two or more sources of molten metal, e.g. two remote melting pots, can be tied together to provide a continuous source of metal, pretreated by flow control elements, to one or more casting machines.</p> |
