Title:
METHOD OF PRODUCING METAL POWDER
Document Type and Number:
WIPO Patent Application WO/1999/033598
Kind Code:
A1
Abstract:
A method of producing metal powder by spraying a cooling liquid to a molten metal flowing down, characterized in that the cooling liquid is continuously discharged towards the molten metal flow passing through a ring-like nozzle from the ring-like nozzle so disposed as to encompass the molten metal flow so that the cooling liquid encompasses the molten flow in the shape of a hyperboloid of one sheet. This invention can efficiently produce metal powder which is very fine and pseudo-spherical and moreover has a small width of particle distribution.
