Abstract

L'invention est un procédé pour former un lingot d'alliage d'aluminium (1). Pendant la coulée de l'alliage d'aluminium, un champ magnétique glissant est appliqué au marais et l'amplitude du champ magnétique est variée périodiquement selon une fréquence (f), de façon à appliquer une force de Lorentz (F) en différents points du marais, la force de Lorentz moyenne, durant une période (P), étant inclinée par rapport à l'axe vertical (Z) selon un angle d'inclinaison (?). Le procédé est caractérisé en ce que la vitesse de coulée (V) et la fréquence (f) sont telles que dans toute la zone médiane du marais, au niveau du front, interface entre le marais et l'alliage solidifié, l'angle d'inclinaison de la force est strictement inférieur à l'angle d'inclinaison du front.The invention is a method for forming an aluminum alloy ingot (1). During the casting of the aluminum alloy, a sliding magnetic field is applied to the swamp and the amplitude of the magnetic field is varied periodically according to a frequency (f), so as to apply a Lorentz force (F) at different points of the marsh, the average Lorentz force, during a period (P), being inclined with respect to the vertical axis (Z) according to an angle of inclination (?). The process is characterized in that the casting speed (V) and the frequency (f) are such that throughout the middle zone of the swamp, at the level of the front, interface between the swamp and the solidified alloy, the angle d The inclination of the force is strictly less than the angle of inclination of the forehead.
