Abstract: 용융공급원료로부터금속분말을생산하기위한장치는고체공급물을용융공급물로용융시키기위한가열원및 용융공급물을담기위한도가니를포함한다. 용융스트림으로서용융공급물을공급하기위해액체공급관이또한제공된다. 플라즈마소스는플라즈마스트림을전달하고, 플라즈마스트림은초음속속도로가속되도록조정되며, 용융스트림에충돌하도록조정되어금속분말을생성한다. 공급튜브는도가니에서초음속플라즈마플럼이용융스트림을분무하는위치까지확장된다. 플라즈마소스는용융스트림을향하여조준된적어도하나의초음속노즐이제공된적어도두 개의플라즈마토치를포함한다. 다중플라즈마토치는, 예를들어, 링형구성과같이초음속플라즈마플럼들이용융스트림을분무하는위치에대해대칭적으로배치된다.

Abstract: An apparatus for producing metallic powders from molten feedstock includes a heating source for melting a solid feedstock into a molten feed, and a crucible for containing the molten feed. A liquid feed tube is also provided to feed the molten feed as a molten stream. A plasma source delivers a plasma stream, with the plasma stream being adapted to be accelerated to a supersonic velocity and being adapted to then impact the molten stream for producing metallic powders. The feed tube extends from the crucible to a location where a supersonic plasma plume atomizes the molten stream. The plasma source includes at least two plasma torches provided with at least one supersonic nozzle aimed towards the molten stream. The multiple plasma torches are disposed symmetrically about the location where the supersonic plasma plumes atomize the molten stream, such as in a ring-shaped configuration.
