ABSTRACT:
A casting assembly has a casting nozzle for dispensing a melt puddle upon a casting surface of a continuously moving chilled substrate. A vibratory support contacts the chilled substrate opposite the casting nozzle and includes an ultrasonic transducer for exciting the substrate. The support applies ultrasonic vibrations through the substrate to the melt puddle prior to the critical period of solidification for enhancing wetting of the substrate and improving heat transfer between the melt puddle and the chilled substrate.
