US Patent:

41770650, Dec 4, 1979

Filed:

Jan 12, 1979

Appl. No.:

6/002843

Inventors:

Joseph A. Clumpner - Creve Coeur MO

Assignee:

Swiss Aluminium Ltd. - Chippis

International Classification:

C22B 902
C22B 908

US Classification:

75 93E

Abstract:

The disclosure teaches an improved method and apparatus for the treatment of liquids with gases and especially for use in the degassing and filtration of molten metal, especially aluminum, using an apparatus which employs a swirling tank reactor. The swirling tank reactor is in the form of a substantially cylindrical chamber and is characterized by having a liquid inlet at the top thereof and at least one gas inlet at the bottom of said substantially cylindrical chamber wherein at least either the liquid inlet or the gas inlet is positioned with respect to the wall of the cylidrical chamber for tangentially introducing either liquid or gas such that the liquid swirlingly flows from said liquid inlet to a liquid outlet. In a preferred embodiment for the degassing and filtration of molten metal, a filter-type medium is positioned beneath said molten metal inlet to filter the molten metal prior to delivering the same to a casting station. Dissolved gases and non-metallic inclusions are thereby abstracted and removed from the melt.

Appl. No.:

6/013029

Inventors:

Joseph A. Clumpner - Creve Coeur MO

Assignee:

Swiss Aluminium Ltd. - Chippis

International Classification:

C22B 902
C22B 908

US Classification:

75 93E

Abstract:

The disclosure teaches an improved design for a swirling tank reactor for use in the degassing and filtration of molten metal. The swirling tank reactor has a larger first cylindrical section and a second smaller cylindrical or converging conical section located beneath said first cylindrical section. Conical shaped fluxing gas inlet nozzles are provided in the walls of both the first and second sections so as to maximize fluxing gas bubble dispersion.
