Abstract
L'invention concerne un procédé qui permet d'affiner la microstructure de métaux et d'alliages coulés par la technique des 'masselottes chaudes', en induisant une cavitation, au moyen de vibrations électromagnétiques ou mécaniques, à l'intérieur d'un résonateur magnétohydrodynamique ou d'un résonateur de Helmholtz, associée à un brassage modéré du métal fondu. Pour mettre en oeuvre le procédé, on utilise un dispositif comprenant une trémie d'entrée (18) pour le métal fondu (20), une lingotière supérieure (22) en céramique pour contenir le métal fondu (20), un réservoir d'eau (24) pour refroidir par eau le métal en train de se solidifier, un système pour agiter le métal fondu (20), tel qu'une pompe électromagnétique alternative (2), une cavité résonante (10), dans laquelle doit être induit le phénomène de cavitation, un champ magnétique fixe B0, et une bobine d'inductance (28) pour produire un brassage modéré le long du trajet de l'écoulement (30).
