Title:
APPARATUS FOR MANUFACTURING METAL POWDER AND GAS INJECTOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/162037
Kind Code:
A1
Abstract:
This apparatus for manufacturing metal powder comprises: a first gas injection nozzle (71) that includes a plurality of injection holes (91) arranged on the bottom surface of a gas injector (200) such that a first ring (61) is drawn near each of a plurality of molten metal nozzle insertion holes (12A, 12B), and injects gas to molten metal flowing down from molten metal nozzles (11A, 11B) to crush the molten metal; a second gas injection nozzle (72) that includes a plurality of injection holes (92) arranged on the bottom surface of the gas injector (200) such that a second ring (62) is drawn outside each first ring (61), and injects the gas in order to prevent metal particles (15) crushed by the first gas injection nozzle (71) from scattering; and a third gas injection nozzle (73) that includes a plurality of injection holes (93) arranged on the bottom surface of the gas injector (200) such that a third ring (63) is drawn outside the second gas injection nozzle (72), and injects the gas onto the inner wall surface of a spray tank (4).
