Abstract
A device (10) for manufacturing a metal alloy blank by centrifugal casting of a molten metal alloy, comprising a centrifugal casting wheel (20), the centrifugal casting wheel (20) being rotary about an axis of rotation (A) and comprising a mold (22) for receiving the molten metal alloy, the mold extending in a radial direction (R1) with respect to the axis of rotation (A). The device (10) comprises at least one magnet arranged in such a way as to induce an electric current in the mold (22) during the rotation of the centrifugal casting wheel (20) about the axis of rotation (A).
Claims12
A device for manufacturing a metal alloy blank by centrifugal casting of a molten metal alloy, comprising a centrifugal casting wheel, the centrifugal casting wheel being rotary about an axis of rotation and comprising a mold for receiving the molten metal alloy, the mold extending in a radial direction with respect to the axis of rotation,
- the device comprising at least one magnet, arranged in such a way as to induce an electric current in the mold during the rotation of the centrifugal casting wheel about the axis of rotation.
A method for manufacturing a metal alloy blank, comprising the following steps:
- melting of the metal alloy;
- pouring of the molten metal alloy into a centrifugal casting wheel, the centrifugal casting wheel being rotary about an axis of rotation and comprising a mold for receiving the molten metal alloy, the mold extending in a radial direction with respect to the axis of rotation;
- rotation of the centrifugal casting wheel about its axis of rotation and solidification of the molten metal alloy inside the mold, in such a way as to obtain the metal alloy blank;
- and
- extraction of the metal alloy blank from the mold,
- a magnetic field being applied to the mold during the rotation step in such a way as to induce an electric current in the mold.
