Title:
METAL STRIP STABILIZER, METHOD FOR MANUFACTURING HOT DIPPED METAL STRIP, AND METAL STRIP
Document Type and Number:
WIPO Patent Application WO/2013/022004
Kind Code:
A1
Abstract:
Provided is a metal strip stabilizer with which loss in vibration suppression performance caused by an induced current between a vibration suppression coil and a position correction coil may be prevented. The metal strip stabilizer of the present invention comprises: a non-contact displacement sensor which measures displacement of a metal strip (2) during online running; a control unit (5) which outputs a vibration suppression signal and a position correction signal after inputting a signal from the non-contact displacement sensor; a vibration suppression coil (7a) which generates a magnetic force according to the vibration suppression signal output from the control unit (5); a position correction coil (7b) which generates a magnetic force according to the position correction signal output from the control unit (5), a winding number thereof being larger than a winding number of the vibration suppression coil (7a); a core (6) where the vibration suppression coil (7a) and the position correction coil (7b) are wound concentrically, the magnetic force generated by the vibration suppression coil (7a) and the position correction coil (7b) being induced to the metal strip (2); and a counter induced current coil (13a) which is disposed in series in an electric circuit supplying electricity to the position correction coil (7b).
