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.
Claims18
A zinc recovery system that reduces the buildup of bottom dross, comprising:
- a coating pot defined by a sidewall and a base, and having a bottom;
- and
- a pump having an intake and an outflow;
- at least one of the intake and the outflow being located near the bottom of the coating pot.
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 an interior defined by a sidewall and a base;
- wherein the pump is configured to move material from the coating pot into the reaction apparatus.
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 an entry port and an exit port;
- wherein the outflow of the pump is in communication with the entry port of the reaction apparatus;
- and
- wherein material exiting the reaction apparatus is directed towards the bottom of the coating pot.
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 vessel;
- wherein the pump is configured to move material from the bottom of the coating pot into the reaction apparatus.
A method for reducing bottom dross in a molten zinc bath, comprising:
- adding aluminum to the molten zinc bath having bottom dross;
- and
- agitating the bottom dross.
A method for reducing bottom dross in a primary molten zinc bath in a coating pot, comprising:
- providing a secondary molten zinc bath in a reaction vessel, wherein the aluminum concentration of the secondary zinc bath is greater than the aluminum concentration of the primary zinc bath;
- and
- interacting the secondary zinc bath with the bottom dross.
