ABSTRACT:
There is disclosed a combination of several novel elements in combination with improved designs of existing elements, to provide a relatively simple means for delivering high melting molten metals, such as magnesium and its alloys, to a continuous caster without exposure of the metal to the ambient atmosphere, at reproducible pressures and quantities to enable the advanced casting technologies to be utilized to their fullest potential. Thus in accordance with the present invention there is described a molten metal handling system, particularly useful for delivering high melting temperature metals in their molten state from a melting pot or crucible to a casting machine, e.g. die caster, strip caster, sand molds and the like, remote from the melting pot or crucible without exposure to the ambient atmosphere. The essential elements of the present molten metal handling system are a pump and heated conduits to carry the molten metal to the casting station. Preferred elements in addition to the pump and conduit are flowmeters and flow control elements. Optionally, two or more sources of molten metal, e.g. two remote crucible or melting pots, can be tied together to provide a continuous source of metal to one or more die casters or strip caster.
