ABSTRACT:
A method is set forth wherein powder is produced by melting metal in a melting furnace where it is then poured into a tundish which directs the molten metal onto a spinning disc means. The tundish is located at the center of a nozzle plate which contains a plurality of annular nozzle means for directing a coolant flow downwardly around the spinning disc means at different radial positions. Controls are provided for controlling atmosphere in said apparatus. Further, controls are provided to control the speed of the disc means and the mass flow of the cooling fluid through each of the nozzle means.
