ELECTROMAGNETIC VIBRATION SUPPRESSION DEVICE AND ELECTROMAGNETIC VIBRATION SUPPRESSION CONTROL PROGRAM

摘要

An electromagnetic vibration suppression device 1 includes a plurality of electromagnet pairs 2 (2A, 2B) disposed in the width direction of a steel sheet Sa. Each electromagnet pair is oppositely disposed in the thickness direction of the steel sheet Sa traveling in a predetermined direction. A control section 4 is adapted to control current to be applied to each electromagnet 2A, 2B to suppress the vibration of the steel sheet Sa traveling between electromagnets 2A and 2B. The control section 4 is arranged to determine an edge position Sae of the steel sheet Sa by computation based on an inputted width dimension of the steel sheet Sa and a meandering amount of the steel sheet Sa inputted therein, and separately control a current amount to be applied to the electromagnets 2A and 2B based on the edge position Sae of the steel sheet Sa.
