A trough including connected walls configured to hold a molten galvanization material within the trough. The trough further includes a first end comprising a first gate system. The trough further includes a second end, opposing the first end, comprising a second gate system. The trough further includes a roller connected, inside the trough, to opposing inside walls of the plurality of connected walls. The trough further includes a sump disposed within the trough. The trough further includes an inlet connected to the sump.

Disclosed is a device for removing mattes from the surface of a liquid metal bath inside a duct of a line for continuously coating a metal strip having first and second faces, the first face being intended to come into contact with a bottom roller, comprising a compartment via which the liquid metal inside the duct is replenished by being drawn off by a pump to which the compartment is connected, characterized in that the compartment is capable of being removed by disassembly means without the metal strip needing to be cut.

A continuous galvanizing apparatus for multiple rods. The apparatus includes a kettle for heating and retaining a liquid therein with at least a portion of the kettle having an open top. A trough assembly retains liquid therein. The trough assembly is arranged above the kettle open top above the liquid level, with the trough assembly having at least one lower chamber within the kettle below a level of the liquid in the kettle. A pump in the lower chamber draws liquid from the kettle to the trough assembly. A plurality of entry openings are provided in the trough assembly along with a plurality of exit openings opposed to and aligned with the entry openings. Adjacent tubes in the trough assembly are aligned with the plurality of entry and exit openings.

A device for removing foreign material from a molten metal surface in a steel sheet hot-dip galvanizing process, of the present invention, comprises: a snorkel part of which the end portion is submerged under the molten metal surface of a hot-dip galvanizing bath so as to encompass a steel sheet inserted into the hot-dip galvanizing bath, in order to prevent the oxidization thereof; a snout including a dam unit having a dam forming part which encompasses the steel sheet from the end portion of the snorkel part so as to be spaced a predetermined gap from same, and which allows a molten galvanizing solution inside the hot-dip galvanizing bath to flow over toward the inner peripheral surface of the snorkel part so as to prevent the foreign material that falls onto the molten metal surface inside the snorkel part from attaching to the steel sheet; and a molten zinc discharge unit which is provided inside the snorkel part so as to pump, toward the molten metal surface inside the hot-dip galvanizing bath, the molten galvanizing solution having flowed over the dam forming part of the damp unit, thereby preventing the foreign material included in the molten galvanizing solution, having flowed over the dam forming part, from mixing into the molten galvanizing solution inside the hot-dip galvanizing bath and re-polluting the molten galvanizing solution or flowing into the snorkel part again.

A method of galvanizing a workpiece. The method is performed using a trough. The trough includes connected walls configured to hold a molten galvanization material within the trough. The trough also includes a first end including a first gate system. The trough also includes a second end, opposing the first end, including a second gate system. The trough also includes a roller connected, inside the trough, to opposing inside walls of the connected walls. The trough also includes a sump disposed within the trough. The method also includes pumping the molten galvanization material into the sump until the molten galvanization material submerges the roller. The method also includes driving the workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system.

A method including manufacturing a trough. The trough includes connected walls configured to hold a molten galvanization material within the trough. The trough is further manufactured to include a first end including a first gate system. The trough is further manufactured to include a second end, opposing the first end, including a second gate system.
