摘要： Provided are an electromagnetic wiping device for controlling the amount of coating of a steel sheet, a steel sheet wiping device including the same, and a method for manufacturing the steel sheet. The present invention can prevent overcoating at least at the edge of the steel sheet by removing a coating layer of at least an edge part of the steel sheet passing through a plating bath by using electromagnetism and forming the gas wiping, and can reduce gas wiping capabilities while maintaining the line speed of the steel sheet so as to reduce the amount of scattered material or dross due to the scattered material, thereby ultimately improving the coating quality and the productivity of the steel sheet.

摘要： There are provided an electromagnetic wiping device, a plated steel sheet wiping apparatus including the electromagnetic wiping device, and a method for manufacturing a plated steel sheet. A portion of a plating layer of a steel sheet having passed through a plating bath is preliminarily removed at least in an edge region of the steel sheet, and a gas wiping operation is performed. Therefore, overplating is prevented at least in the edge region of the steel sheet. In addition, since the load of gas wiping can be reduced while maintaining the line speed of the steel sheet, the quantity of scattered particles and the formation of dross can be reduced for improving the plating quality of the steel sheet and the productivity of a manufacturing process.
