Abstract
Described herein are techniques for improving the grain structure of a metal product by applying ultrasonic energy to a continuously cast metal product at a position downstream from the casting region and allowing the ultrasonic energy to propagate through the metal product to the solidification region. At the solidification region, the ultrasonic energy can interact with the growing metal grains, such as to deagglomerate and disperse nucleating particles and to disrupt and fragment dendrites as they grow, which can promote additional nucleation and result in smaller grain sizes.
