Document Type and Number:
WIPO Patent Application WO/2019/112052
Kind Code:
A1
Abstract:
This metal powder manufacturing device comprises: an atomization chamber (4); and a plurality of atomization nozzles (20A, 20B) that carry out liquid atomization of a melted metal, in the atomization chamber (4). The plurality of atomization nozzles (20A, 20B) each include: molten metal nozzles (11A, 11B) for causing the melted metal to flow downward toward the inside of the atomization chamber (4); and gas injection nozzles (2A, 2B) a plurality of which are disposed around the molten metal nozzles and that are for causing a gas stream to collide with the melted metal which flows downward from the molten metal nozzles.
