Publication number: 20210220905Abstract: A method for casting a metal alloy in an ingot mold extending along a vertical axis, the horizontal section of the ingot mold being parallelepiped in shape. During casting, a travelling alternating magnetic field is applied to a liquid phase of the alloy, the magnetic field having a maximum amplitude propagating along an axis of propagation. Under the effect of the magnetic field, a Lorentz force is applied to the liquid phase of the alloy, such that a Lorentz force of maximum intensity propagates along the axis of propagation. The method includes modulating the maximum intensity of the Lorentz force propagating along the axis of propagation. This modulation is obtained by varying, over time, one or more parameters, referred to as force parameters, governing the Lorentz force. An ingot obtained by the method is also described.Type: ApplicationFiled: May 17, 2017Publication date: July 22, 2021Applicant: CONSTELLIUM ISSOIREInventors: Philippe JARRY, Fabio TAINA, Jean-Louis ACHARD, Marc BERTHERAT, Pierre-Yves MENET, Mircea CABLEA
