METAL STRIP STABILIZATION APPARATUS AND METHOD FOR MANUFACTURING HOT-DIPPED METAL STRIP USING SAME

WIPO Patent Application WO/2016/080083

A1

This metal strip stabilization apparatus is provided with a displacement measurement unit, a control unit, and an electromagnet unit. The displacement measurement unit performs non-contact measurement of displacement of a metal strip during travel. On the basis of a metal strip displacement measurement signal provided by the displacement measurement unit, the control unit generates a vibration suppression signal for controlling vibration suppression of the metal strip and a position correction signal for controlling position correction of the metal strip. The electromagnet unit has a vibration suppression coil for generating a first magnetic energy on the basis of the vibration suppression signal, a position correction coil for generating a second magnetic energy on the basis of the position correction signal, and a core about which the vibration suppression coil and the position correction coil are concentrically wound, and which guides the first magnetic energy and the second magnetic energy to the metal strip. The number of turns of the position correction coil is 2-5 times the number of turns of the vibration suppression coil. The electromagnet unit uses the first magnetic energy to suppress vibration of the metal strip and the second magnetic energy to correct the position of the metal strip.
