Abstract (en)
[origin: EP2711111A1] 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 11 supplies a downward flow 1 of molten metal, and a plurality of jet burners 12 emit flame jets 12a to the downward flow 1 of the molten metal supplied from the supply means 11. Each of the jet burners 12 is provided to emit the flame jet 12a from the same angle and from each of positions rotationally symmetrical with each other with respect to the downward flow 1 of the molten metal.
