FIELD: metal powders.
SUBSTANCE: device relates to the production of metal powders. The device contains a water-cooled working chamber with a controlled atmosphere, a plasmatron installed in the upper part of the working chamber for forming a plasma flow, several devices for feeding bar material into the plasma flow and a powder collector installed in the lower part of the working chamber. The bar material feed devices are equipped with current leads that ensure the combustion of an independent electric arc between the free ends of the bar materials, as well as an annular gas nozzle installed in the chamber counterflow to the plasma jet to circulate the gas flow against the flow of powder particles.
EFFECT: increased productivity of obtaining spherical powders of fine fraction in the absence of particle adhesion.
