Appl. No.:

12/595757

Inventors:

Mark A. Bright - Sewickley PA, US
Gregory C. Becherer - Hinckley OH, US
Robert L. Grodeck - Cleveland OH, US

International Classification:

US Classification:

427433, 118429

Abstract:

A continuous galvanizing line uses a coating pot containing a molten zinc bath having bottom dross and further comprises a pump. The pump agitates the bottom dross so the bottom dross interacts with aluminum and converts to top dross, which can be removed without needing to stop the galvanizing line. A reaction vessel may also be used to provide a higher concentration of aluminum to react with the bottom dross.
