First Claim
1. A molten metal processing device for a casting wheel on a casting mill, the casting wheel including a containment structure for receiving and casting molten metal and a band enclosing a portion of the containment structure in which the molten metal is cast, the band extending around a portion of a perimeter of the casting wheel, comprising:
- an assembly mounted on an outer surface of the casting wheel band, including,at least one vibrational energy source which supplies vibrational energy to molten metal cast in the casting wheel, anda support device holding said at least one vibrational energy source,wherein the vibrational energy is supplied from the vibrational energy source to the molten metal cast through an intervening liquid medium in contact with the casting wheel band.

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.

23. A molten metal processing device comprising:
-
a source of molten metal; an ultrasonic degasser including an ultrasonic probe inserted into the molten metal; a casting wheel for reception of the molten metal; a band extending around a portion of a perimeter of the casting wheel; an assembly mounted on the band, including, at least one vibrational energy source which supplies vibrational energy through the band to molten metal cast in the casting wheel while the molten metal in the casting wheel is cooled, and a support device holding said at least one vibrational energy source, wherein the vibrational energy is supplied from the vibrational energy source to the molten metal cast through an intervening liquid medium. - View Dependent Claims (24)

25. A molten metal processing device for a casting wheel on a casting mill, comprising:
-
at least one vibrational energy source mounted in a fixed position on the casting mill and mounted so as to be in contact with a band of the casting wheel through a cooling medium and the vibrational energy source configured to supply vibrational energy to metal cast in the casting wheel while the metal cools and while a rim of the casting wheel rotates past the vibrational energy source, and wherein the vibrational energy is supplied from the vibrational energy source to the metal cast in the casting wheel through the intervening cooling medium. - View Dependent Claims (26, 27, 28)
