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. The trough is further manufactured to include a sump disposed within the trough. The trough is further manufactured to include a side braces connected to an outside wall of the connected walls. The side braces extend outwardly from the outside wall. The trough is further manufactured to include an inlet connected to the sump, the inlet disposed at a perpendicular angle relative to the outside wall and further disposed between the side braces.

A bearing system is configured for use between a roller journal and a support frame in a molten metal hot dip coating line for steel strip. The system includes a sleeve configured to attach to a journal and a bearing assembly comprising a bushing rotatably supporting the sleeve. The sleeve is made from solid cemented carbide. An elastically compressible layer joins the sleeve to the journal, wherein the sleeve and the journal are mechanically coupled to rotate together.

An installation for adjusting a thickness of a hot liquid coating on a traveling strip with suppression of angel wing flow defects, the traveling strip having a thickness equal to or greater than 2 mm, and for cooling the coating, the coating thickness being in a range above 25 m, the installation successively include, from a bottom upwards, on either side of the traveling strip: a wiping device having gas knives for wiping excess liquid from the coated strip at an outlet of a liquid bath; at least one conventional gas cooling header with gas blowers for solidifying the coating; and a water cooling and freezing header for producing airless spraying of demineralized water for skin freezing of the coating, the header being located as close as possible to the wiping device and between the wiping device and the at least one conventional gas cooling header.

Systems and methods for galvanizing objects are described. In some aspects, systems and methods incorporate a trough configured to hold a molten galvanization material. The trough can include connected walls configured to hold a molten galvanization material within the trough. In some aspects, the trough further includes a first end comprising a first gate system. The trough can further include 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.

It is provided a method and device to control the thickness of a metallic coating on a steel wire. A device (101) for controlling a metallic coating thickness on a steel wire comprises: a digital proportional valve (113); a digital flow meter (111); a pressure sensor (115); a thickness sensor (105); a gas nozzle (119); a computer (107); and is characterized in that the relation between the gas flow measured by said digital flow meter (111) and the coating thickness measured by said thickness sensor (105) for said gas nozzle (119) is linear or parabolic.
