In a continuous galvanizing line, oscillation of a steel strip 10 withdrawn from a molten zinc metal bath (12) is reduced by liquid-cooled anti-vibration magnets (34, 36, 38, 40) disposed in the vicinity of the respective side edges of the steel strip (10). The magnets cause tension in the strip in the direction of the strip width and amplitude of the oscillation of the strip perpendicular to the strip surfaces is reduced. Also, by magnetic force of the magnet, bending of the running strip is cured and a uniform coating is obtained. The gap between the magnets and the strip side edge is automatically controlled using a motor 48, actuated by detecting signals derived from sensors scanning the gap. Such anti-vibration magnets can also reduce oscillation in other strip processing lines, and an application to a strip inspection line is disclosed. <IMAGE> |
