Abstract
A nozzle assembly for atomizing a stream of molten metal includes a refractory metal-transmitting nozzle having a short metering orifice at its entrance end and a relatively long divergent discharge passage terminating at a flat annular land formed at the bottom end of the metal-transmitting nozzle. The metal-transmitting nozzle is seated in an opening in the bottom of a tundish or other source of molten metal with its upper end containing its metering orifice projecting into the molten metal reservoir. The lower-end portion projects from the bottom of the tundish and through the central portion of an atomizing fluid nozzle assembly in which it seats. The central portion of the atomizing fluid nozzle assembly projects below the bottom member of the atomizing fluid nozzle assembly and forms an atomizing fluid orifice therewith. The process of utilizing the apparatus for atomizing powder is described in which a molten metal film is formed around the outer bottom portion of the metal-transmitting nozzle which extends below the central portion and orifice of the atomizing fluid nozzle assembly.
