When applied under appropriate conditions vibration can cause substantial refinement of grain structure in solidifying metals. It is generally accepted that the refinement is due to an increase in dendritic debris acting as nuclei for equiaxed grain formation and there is strong evidence to suggest that the onset of this mechanism is governed by the frequency amplitude product of the vibration. This report describes research into the refinement of continuously cast billet solidification structures by application of vibration in or around the area of the mould. Finite element modelling was carried out to investigate the response of a continuous casting strand to vibrational excitation in terms of resonant modes and forced excitation. A series of control and vibration pilot plant trials for high carbon and ferritic stainless steels was completed and billets from control and vibrated casts were sectioned and compared.
