Abstract (en)
[origin: WO9221462A1] A method and a device for making metallic powder, by which irregularity in cooling speed is hardly caused, high speed cooling and solidification are made possible, and fine grain powder can easily be obtained. Cooling liquid is spouted along the inner peripheral surface of a cooling cylinder (1) so that a cooling liquid layer (9) is formed which moves while turning along the inner peripheral surface of said cylinder (1), toward the side of a cooling liquid discharging end of said cylinder (1); molten metal (25) is supplied into the inner space (23) inside said cooling layer (9); jetting gas (26) directed toward the cooling liquid layer (9) is blown to said molten metal (25) for fragmentation and molten metal thus fragmented is supplied to the cooling liquid layer (9); and cooling liquid containing metallic powder solidified in the cooling liquid layer (9) is discharged from the discharging end of the cooling cylinder (1) to the outside.
