ABSTRACT:
In apparatus for producing metal powder by rapid solidification of molten metal particles flung into a quenching chamber from a rotating disk through vertical zones of cooling fluid, improved cooling fluid flow, improved operating efficiency and low pressure losses are provided by having the cooling fluid introduced into the quenching chamber via a plurality of cylindrical tubes each having an inlet within a coolant fluid manifold and an outlet opening into the quenching chamber. Each tube including means for creating a cooling fluid vortex flow therein which exits from the tube outlet into the quenching chamber as an expanding cone of swirling fluid. A plurality of these tubes are appropriately located around the rotating disk to create a desired pattern of cooling fluid flow around the disk and through which the molten metal particles will pass as they solidify into the powder.
