Abstract

On produit dans le bain de fusion 3 contenu dans la lingotière 2, un champ d'ultrasons basse fréquence produit par un convertisseur 6 et transmis, éventuellement par l'intermédiaire d'une pièce intermédiaire 5 à la pièce de transmission 1 au contact de la matière en fusion. Les longueurs de la piece intermédiaire 5 et de la pièce de transmission 1 au contact du bain 3 constituent des multiples entiers de la demi-longueur d'onde des ultra-sons basse fréquence.Is produced in the molten bath 3 contained in the mold 2, a low frequency ultrasound field produced by a converter 6 and transmitted, optionally via an intermediate part 5 to the transmission part 1 in contact with the molten material. The lengths of the intermediate piece 5 and of the transmission piece 1 in contact with the bath 3 constitute integer multiples of the half-wavelength of low-frequency ultrasound.
