Abstract

TRATAMENTO ULTRASSÔNICO PARA REFINAMENTO DA MICROESTRUTURA DE PRODUTOS FUNDIDOS CONTINUAMENTE. A presente invenção refere-se a técnicas para melhorar a estrutura do grão de um produto de metal, aplicando energia ultrassônica para um produto de metal fundido continuamente, em uma posição à jusante da região de fundição, e possibilitando a energia ultrassônica se propagar através do produto de metal para a região de solidificação. Na região de solidificação, a energia ultrassônica pode interagir com os grãos de metal que estão crescendo, de tal maneira para desaglomerar e dispersar partículas nucleantes, e para romper e fragmentar dendritos quando eles crescem, que pode promover nucleação adicional e resultar em tamanhos de grãos menores.
