Abstract
An electromagnetic strip stabilizer includes: a pair of electromagnets, opposed to each other, that generate magnetic forces to act on a steel strip passing between the electromagnets after a surface coating process being applied to the steel strip; a pair of sensors, each sensor provided for each of the electromagnets, that detect a distance between a corresponding one of the electromagnets and the steel strip; and a control section configured to control a current supplied to each of the electromagnets and control a vibration of the steel strip at least based on the distance between the steel strip and each of the electromagnets detected by each of the sensors. The control section determines control gains used to control the current supplied to each of the electromagnets at least based on a thickness and a width of the steel strip.
