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.

A method and an apparatus for environmentally-friendly batch hot-dip coating of high-performance alloy are provided. The method is that workpiece is heated to the process temperature in the heating box with inner gas before galvanizing. The heating box body consist of two or three zones, which are waiting zone, heating zone and post-plating turnover zone (the post-plating turnover zone can be omitted). A zinc pot is arranged in the heating zone, and the zinc pot is configured for hot-dip coating. Workpieces can be processed with zinc or zinc-based alloys. A transporting device is configured to successively transport in a sealed state the workpiece to be processed to the waiting zone, the heating zone, the zinc pot, and the post-plating turnover zone (the post-plating turnover zone can be omitted). The new method realizes hot-dip coating with zinc and other zinc-based alloys without the use of the flux.

The present invention relates to a method for coating a component of a turbomachine in a bath, in which method, the component is partially immersed in the bath containing a coating material; the component is rotated at least intermittently around an axis of rotation, which lies outside of the bath, during the at least partial immersion; the component is at most immersed partially over and beyond the rotation.

A continuous galvanizing apparatus for rods and process therefor. The apparatus includes a liquid reservoir. A plurality of adjacent tubes each pass into, through, and out of the liquid reservoir. Each of the adjacent tubes has at least one opening within the liquid reservoir so the tubes are in fluid communication with the reservoir. A rod drive mechanism moves a plurality of adjacent rods into, through, and out of the plurality of adjacent tubes. A kettle is provided beneath both the liquid reservoir and beneath the tubes. At least one pump pumps liquid from the kettle to the liquid reservoir so that liquid is continuously cycled to the tubes.

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.

The present invention relates to a method and an apparatus for treating already galvanized steel parts having a zinc coating, in particular for remanufacturing used galvanized steel parts. The method comprises the following steps: A) checking the galvanized steel part for suitability with a view to remanufacturing; B) preparing the galvanized steel part mechanically and/or chemically; and C) rejuvenating the zinc coating of the steel part.

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. The trough is further manufactured to include a roller connected, inside the trough, to opposing inside walls of the connected walls.
