Abstract
A molten metal processing device including an assembly mounted on the casting wheel, including at least one vibrational energy source which supplies vibrational energy to molten metal cast in the casting wheel while the molten metal in the casting wheel is cooled, and a support device holding the vibrational energy source. An associated method for forming a metal product which provides molten metal into a containment structure included as a part of a casting mill, cools the molten metal in the containment structure, and couples vibrational energy into the molten metal in the containment structure.
