PURPOSE:To change the direction of a plated steel strip of high temp. in noncontact by arranging plural electromagnets in such a manner that the shape of the sucking face against the steel strip is formed into a circular-arc one, controlling an exciting current and floating the steel strip up to a certain place by a magnetic force. CONSTITUTION:Electromagnets 11a to 11c are arranged in a curcular-arc state against a steel strip 1. Sensors 12a to 12c measure the distance between the electromagnets 11a to 11c and the steel strip 1 to control an exciting current and to float the steel strip 1 up to a certain place by a magnetic force. An auxiliary roll 13 is needless in the process of ordinary operation, but it is used in the case of sheet passing in the initial stage or in the case of an accident at the time of power failure. The progressing direction of the plated steel strip 1 of high temp. can be changed in noncontact.
