スワイピング装置。[Scope of claim for utility model registration] (1) Continuous molten zinc having gas wiping nozzles for adjusting the zinc coating amount on both the front and back surfaces of the steel strip, and an edge overcoat prevention plate on the widthwise extending surface of the steel strip. In the gas wiping device for plating, the lower part of the edge overcoat prevention plate is shaped to prevent the downwardly escaping gas of the wiping gas injected from the wiping nozzle from colliding directly with the bath surface of molten zinc. Gas wiping equipment for hot dip galvanizing. (2) The gas wiping device for continuous hot-dip galvanizing according to claim 1, wherein the lower front and back surfaces of the edge overcoat prevention plate are curved so as to be further apart from each other as they move downward. (3) The gas wiping device for continuous hot-dip galvanizing according to claim 1, characterized in that projections parallel to the bath surface are provided on the lower front and back surfaces of the edge overcoat prevention plate. (4) The gas wiping device for continuous hot-dip galvanizing according to claim 1, characterized in that the edge overcoat prevention plate has projections inclined outwardly and downward on the lower front and back surfaces of the edge overcoat prevention plate.
