1. A molten metal conveyor comprising:
a receptor plate in contact with molten metal during transport of the molten metal;
said receptor plate extending from an entrance where molten metal enters onto the receptor plate to an exit where molten metal exits the receptor plate; and
at least one vibrational energy source which supplies vibrational energy directly to the receptor plate in contact with molten metal;
wherein the at least one vibrational energy source comprises a plurality of transducers arranged in an ordered pattern on the receptor plate having a higher density of said transducers at an outlet of the receptor plate.
 
17. A casting mill comprising:
a casting mold configured to cool molten metal, and
the conveyor of claim 1.
