Abstract: To provide an apparatus for producing a metal powder and a method of producing a metal powder capable of obtaining a metal powder having a finer particle size of excellent quality. A supersonic combustion flame is intensively injected into a downwardly supplied molten metal, the intensive combustion flame is jetted directly downwardly as a focused jet flow, the focused jet flow thrusts into a turning water flow formed along an inner peripheral surface of a pulverization cooling cylinder whose axis line is inclined from a vertical direction, and an intensive position of the combustion flame is in an open space above the turning water flow.

Abstract: A metal powder production method and a metal powder production device capable of reducing the size of the device, reducing costs, and obtaining spherical metal powder are provided. Supply means supplies a downward flow of molten metal, and a plurality of jet burners emit flame jets to the downward flow of the molten metal supplied from the supply means. Each of the jet burners is provided to emit the flame jet from the same angle and from each of positions rotationally symmetrical with each other with respect to the downward flow of the molten metal.
