In the present invention, the electroplating continuous process line of the steel mill, the device operation by the action of the super strong magnet ring 15 is automatically adapted to the steel plate width when the steel plate width changes, so that the anti-stripe nozzle solution is appropriate to the steel plate width It is possible to prevent solution contamination streaks and plating roll contamination streaks by spraying a lot, and excessive solution is sprayed on the plating rolls to contaminate the plating band 4 to prevent defects such as plating spots. The present invention relates to a solution generation nozzle apparatus for preventing streaking of a plating cell conversion roll.

Stripping prevention nozzle solution of the plating cell conversion roll (2) used to provide a constant flow of the electrolyte at the proper flow rate to the steel sheet (1) during the plating operation in the cold-rolling side of the steel mill electroplating process The solution is uniformly sprayed and adsorbed into the plating roll (C / Roll) in a state that prevents the conversion line (D / R) contamination mark. In the case of the prevention nozzle, the nozzle injection liquid of the part wider than the width of the steel sheet is sprayed onto the plating band of the plating roll to contaminate the plating band, resulting in plating spots and plating contamination line marks. If spraying is narrower than the width and spraying nozzle is not properly applied to the steel sheet, the unsprayed portion of the steel sheet will have the stripe quality defect. Valves and nozzles that are closed at both edges are frequently clogged and stuck due to the Kcl component contained in the liquid flow. As a problem of the plating spot (spot), there was a problem that the solution contamination stripes and plating roll contamination stripes occur.

The present invention was devised to solve the above problems, the device operation by the action of the super strong magnet ring 15 is automatically made to match the steel plate width when the steel plate width is changed by working with the apparatus of the present invention Stripe prevention nozzle solution can be sprayed appropriately according to the width of steel plate to prevent solution contamination streaks and plating roll contamination streaks.Excessive solution is sprayed on plating rolls and contaminates the plating band 4, resulting in plating spots.
