摘要： An apparatus, system and method for viewing an industrial process in an obscuring environment, such as molten metal atomization, is disclosed. An enclosure defining a chamber for containing a particulate form from atomized liquid metal has a nozzle for atomizing liquid metal mounted thereon in communication with the chamber whereby particles recirculate throughout the chamber. The nozzle being comprised of a cylindrical plenum means and a melt guide tube extending axially therethrough to an exit orifice. The plenum means is configured to provide a jet of atomizing gas converging in an atomizing zone extending from the exit orifice. A viewing means extends through the enclosure to a viewing orifice adjacent the atomization zone, the viewing means being configured to extend a field of view through the chamber to the atomization zone. A purging gas flow is provided in the viewing means to minimize atomized particles from contacting the window, and an image of the atomization zone is generated by viewing through the window.

摘要： An apparatus and method for atomizing liquid metal are disclosed. A liquid metal supply is coupled to a nozzle for atomizing a stream of liquid metal in an atomizing zone extending from the nozzle. A viewing instrument provides a field of view extending to the atomization zone. A sensor coupled with the viewing instrument generates an image of the atomizing zone, and a control adjusts a flow rate of the stream responsive to the image.

摘要： An apparatus for viewing the atomization of liquid metal is disclosed. A nozzle for atomizing liquid metal having a cylindrical plenum, and a melt guide tube extending axially therethrough to a melt exit orifice. The plenum defines an inner chamber coupled with an atomizing gas orifice spaced from the exit orifice and configured to provide an annular jet of atomizing gas converging in an atomizing zone extending below the exit orifice The plenum having an inner sidewall and an outer sidewall defining the inner chamber therebetween. The inner sidewall extends below the exit orifice so that the inner sidewall is spaced from the atomizing zone. A cylindrical sleeve extends through the outer sidewall to a first end in the inner chamber. A camera mounted in the sleeve has a field of view extending from the first end. A transparent window is mounted to seal the first end. The sleeve is positioned so the field of view extends through the atomization zone. A porthole extends through the inner sidewall along the field of view to provide a view of the atomization zone to the camera, and for a gas flow therefrom.

摘要： A nozzle for atomizing molten metal to provide a powder having improved yield of fine particles is disclosed. The nozzle is comprised of a gas plenum, a melt delivery tube, and an annular inner wall means within the gas plenum for delivering atomizing gas to the exit orifice of the melt delivery tube. The exit orifice of the melt delivery tube has a ratio of inside diameter to outside diameter that provides a reduced flow of liquid through the tube during atomization.
