Abstract

The invention is directed to a process for producing metal powder through atomizing in which a molten metal stream is subjected to the influence of a plurality but correlated sets of atomization jets by virtue of which a disintegrating medium exits from the jets at a velocity of at least Mach No. 1, the medium from one set of jets being angled to strike the falling molten body at a point below and at an angle less than the medium dispensed from the other set of jets, whereby less flake and filigree are formed, a higher powder yield obtains, lower medium pressure can be used, etc.
