Provided are a device and a method for controlling the traveling position of a steel sheet, whereby it becomes possible to continue the control sustainably without bringing an electromagnet into contact with the steel sheet even when the position of the steel sheet deviates from a predetermined position. The traveling position of a steel sheet can be stabilized by controlling in such a manner that the current to be passed through an electromagnet for controlling the traveling position is increased or decreased in accordance with the distance between the traveling position of the steel sheet and a preset target position when the traveling position of the steel sheet is farther away from a preset threshold value relative to the position of the electromagnet, and the current to be passed through the electromagnet is decreased by a certain value regardless of the above-mentioned distance when the traveling positon of the steel sheet is closer to the preset threshold value relative to the position of the electromagnet. |
