A device for the preparation of an alloy in powder form, by rapid solidification.

摘要

The invention relates to a process for the production of metal powders by centrifugal atomization, and a device for implementing said method. & br / the process of production of metal powders by centrifugal atomization according to the invention, consisting in supplying a cup in rotation by the molten metal, is characterized in that the molten metal contained in a crucible equipped at its lower part of a nozzle, is extracted from said crucible by the depression created by the disk in rotation about a vertical axis, the upper face of the cup and the lower opening of the nozzle being opposite and substantially parallel, the opening of the nozzle being centered on the cup, the distance between the upper face of the cup and the lower opening of the nozzle being such that the molten metal contained in the nozzle wets the face of the cup when that - latter is static.
