    摘要: A control method of a metal powder manufacturing apparatus, the metal powder manufacturing apparatus including a crucible housed in a dissolving tank, a molten metal nozzle attached to a bottom surface of the crucible, a plurality of gas injecting nozzles arranged on a periphery of the molten metal nozzle within a spray tank, and an orifice portion disposed in an upstream portion of a flow passage in the molten metal nozzle, an inside diameter of the orifice portion being equal to or more than 0.8 mm and equal to or less than 3 mm, the control method including: making a pressure (Ps) of the spray tank higher than a total value of pressure (Ph) acting on an upper end of the molten metal nozzle and a pressure (Pm) of the dissolving tank when a melting raw material is molten within the crucible; and making the pressure (Ps) of the spray tank lower than the total value of the pressure (Ph) acting on the upper end of the molten metal nozzle and the pressure (Pm) of the dissolving tank when a molten metal within the crucible is made to flow down into the spray tank via the molten metal nozzle.

    摘要: Methods and apparatus for producing large diameter superalloy ingots are disclosed. A material comprising at least one of a metal and a metallic alloy is introduced into a pressure-regulated chamber in a melting assembly. The material is subjected to a wide-area electron field within the pressure-regulated chamber to heat the material to a temperature above the melting temperature of the material to form a molten alloy. At least one stream of molten alloy from the pressure-regulated chamber is provided from the melting assembly and is fed into an atomizing assembly, where particles of the molten alloy are generated by impinging electrons on the molten alloy to atomize the molten alloy. At least one of an electrostatic field and an electromagnetic field are produced to influence the particles of the molten alloy. The particles of the molten alloy are deposited onto a collector in a spray forming operation to form an alloy ingot.

    摘要: One non-limiting embodiment of an apparatus for forming an alloy powder or preform includes a melting assembly, an atomizing assembly, and a collector. The melting assembly produces at least one of a stream of a molten alloy and a series of droplets of a molten alloy, and may be substantially free from ceramic in regions contacted by the molten alloy. The atomizing assembly generates electrons and impinges the electrons on molten alloy from the melting assembly, thereby producing molten alloy particles.
