STEEL STRIP STABILISATION DEVICE

Title:

STEEL STRIP STABILISATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/165679

Kind Code:

A1

Abstract:

Provided is a steel strip stabilisation device which allows shape correction and vibration suppression in steel strip, and particularly plated steel strip, in a non-contact fashion. The configuration of one example of the steel strip stabilisation device, consists of: a device support which is disposed on at least one side of advancing steel strip; and a steel strip stabilisation means incorporating a magnetic field generating pole of which one or more is provided facing the steel strip on the device support, and a pole expanding part provided so as to increase the steel strip attraction force on the end part on the steel-strip side of the magnetic field generating pole; and is configured so as to allow shape correction or vibration suppression in the steel strip. The present invention increases the (electro)magnetic attraction force on plated steel strip that has passed through a plating tank, and thereby effectively ensures shape (curvature) correction or vibration suppression (damping) in the plated steel strip and prevents plating variations in the steel strip, and ultimately makes it possible to improve the quality of the plating of the steel strip.
