Method For Controlling The Production Of Atomized Powder

View page
US Patent:
45856010, Apr 29, 1986
Filed:
May 3, 1984
Appl. No.:
6/595610
Inventors:
A. David Booz - New Kensington PA
Kalman E. Buchovecky - Oakmont PA
Walter S. Cebulak - New Kensington PA
Ray A. Kuchera - Rockdale TX
David D. White - Rockdale TX
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
B29B 900
US Classification:
264 12
Abstract:
An improved system for the production of particulate metal is disclosed. The system comprises a containment vessel having a sidewall extending to an endwall, a source of metal external to said vessel and nozzle means carried by said endwall, said nozzle means including a central bore and providing communication between said vessel and said external source of metal, the sidewall and endwall cooperating with the nozzle means to seal off the interior of said vessel and the metal particles therein from the area adjacent said source of molten metal. Further, the system comprises a source of atomizing gas flowing through said nozzle means into said vessel and means for redirecting said atomizing gas flowing into said vessel into said central bore to remove deposition in said bore.

Apparatus For The Production Of Atomized Metal Particles

US Patent:
44641036, Aug 7, 1984
Filed:
Aug 31, 1982
Appl. No.:
6/413514
Inventors:
Robert A. Ramser - New Kensington PA
A. Daivd Booz - New Kensington PA
Daniel R. Barch - Natrona Heights PA
Walter S. Cebulak - New Kensington PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
B01J 204
US Classification:
425 7
Abstract:
Apparatus is provided for the production of atomized metal comprising a containment vessel having a sidewall terminating in a bottom plate through which atomizing gas and molten metal from a molten metal source external to said vessel enter said vessel through nozzle means sealed thereto. An air ingress port is provided in the vessel spaced from said bottom plate; the sidewall and bottom plate cooperating with said nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal; thereby providing an essentially closed vessel, particularly with respect to the area in which the nozzle means are mounted.

Method For Collection Of Atomized Metal Particles

US Patent:
44578814, Jul 3, 1984
Filed:
Sep 10, 1982
Appl. No.:
6/416603
Inventors:
A. David Booz - New Kensington PA
Daniel R. Barch - Natrona Heights PA
Walter S. Cebulak - New Kensington PA
John B. Kapustay - Pocos De Caldas, BR
Adam J. Sartschev - Allison Park PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
B01J 204
US Classification:
264 12
Abstract:
An improved method for the production of particulate metal utilizes a containment vessel having a cylindrical shell and an bottomplate, a source of metal external to the vessel, nozzle means carried by the bottomplate and providing communication between the vessel and the external source of metal, gas ingress port spaced from the bottomplate and an exit port, means provided downstream of the vessel for collecting the metal particles swept from the vessel, and aspirating means for drawing collecting gases into the vessel through the ingress port and for carrying the particulate metal from the vessel to the collecting means.

Metal Article And Powder Alloy And Method For Producing Metal Article From Aluminum Base Powder Alloy Containing Silicon And Manganese

View page
US Patent:
41359224, Jan 23, 1979
Filed:
Dec 17, 1976
Appl. No.:
5/751731
Inventors:
Walter S. Cebulak - New Kensington PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
C22C 2102
US Classification:
75143
Abstract:
A method is provided for producing a metal article from an Al-Si-Mn powder alloy. The alloy is produced by alloying elements in a molten state and a powder of the alloy is produced by atomization. Powder is heated, worked into a finished article of at least 99% density. A metal article produced has a coefficient of thermal expansion less than 11. 0. times. 10. sup. -6 inch/inch/. degree. F and relatively high strength at temperatures greater than 400. degree. F (478. degree. K). Article produced is ideally suited for uses, such as piston, requiring limited thermal expansion while maintaining high temperature strength. An aluminum base powder alloy provided consists essentially of 10 to 25%, Si, 2 to 5% Mn, the balance essentially aluminum and incidental elements and impurities, and is substantially free of Mg, Zn and Ni. Additive elements may be Fe or Cu and Cr, V Zr and Ti. The powder alloy can be atomized in a temperature range of 1400 to 1600. degree.
