Abstract

"APARELHO E MéTODO PARA A PRODUçãO DE MATERIAL SEMI-SóLIDO". Trata-se de um aparelho e processo para a produção de material semi-sólido adequado para a fundição direta formando um componente no qual o material semi-sólido é formado a partir de um material em fusão e o material em fusão é introduzido em um recipiente. O semi-sólido é produzido a partir do mesmo por meio de agitação, cisalhamento e controle térmico do material em fusão. O material semi-sólido é mantido em um estado substancialmente isotérmico dentro do recipiente pelo controle térmico apropriado e através da misturação tridimensional. Estendendo-se a partir do recipiente encontra-se um meio para a remoção do material semi-sólido a partir do recipiente, incluindo um mecanismo de temperatura para controlar a temperatura do material semi-sólido dentro do meio de remoção.
