ELECTROMAGNETIC WIPING DEVICE, STEEL SHEET WIPING DEVICE INCLUDING SAME, AND METHOD FOR MANUFACTURING STEEL SHEET

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.

主权项

1. An electromagnetic wiping device comprising:
a device base disposed to a side of a steel sheet having passed through a plating bath; and an electromagnetic wiper disposed on the device base to generate a varying magnetic field for controlling a thickness of a plating layer formed on the steel sheet.
