FIELD: powder metallurgy.
SUBSTANCE: invention relates to the field of powder metallurgy, in particular, to production of metal powders with a spherical particle shape. The plasma unit for spheroidising metal powders by melting in a flow of thermal plasma of an inert gas consists of an electric arc plasma torch, supply and input assemblies for powdered raw materials, a cylindrical powder processing chamber, a filter, containers for unloading the processed powder with sealed gates, a gas recirculation system wherein an oxygen content sensor and a unit for purification of gases from oxygen are present, interconnected.
EFFECT: prevented introduction of oxygen impurities into the processed metal powder.
