1. A galvanizing bath apparatus for reducing the buildup of bottom dross, comprising:
- a coating pot defined by a sidewall and a base, and having a bottom;
a pump, the pump having an intake and an outflow; and
a reaction apparatus having a sidewall and a bottom wall, an entry port in said sidewall and an exit port in said bottom wall;
wherein the outflow of the pump is in communication with the entry port of the reaction apparatus;
wherein said exit port faces said coating pot bottom such that material exiting the reaction apparatus is directed towards the bottom of the coating pot;
wherein the reaction apparatus is configured to allow matter in the interior of the reaction apparatus to move into the coating pot and introduce the matter into the coating pot near the bottom; and
wherein the reaction apparatus further comprises a pipe in fluid communication with said exit port which opens near the bottom of the coating pot.

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.

2. A galvanizing bath apparatus for reducing the buildup of bottom dross, comprising:
-
a coating pot containing a primary zinc bath defined by a sidewall and a base, and having a bottom; a pump, the pump having an inlet adjacent the coating pot bottom and an outlet remote from the coating pot; and a reaction vessel separated from the coating pot and containing a second zinc bath; wherein the primary zinc bath and the second zinc bath are not in fluid communication other than the pump configured to move material from the bottom of the coating pot into the reaction vessel. - View Dependent Claims (6, 7)
