ABSTRACT:
In a continuous galvanizing line, oscillation of a steel strip withdrawn from a molten zinc metal bath is prevented by anti-vibration magnets disposed in the vicinity of the respective side edges of the steel strip. The magnets cause tension in the strip in a direction of 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 uniform coating is obtained. A gap between the magnet and the strip side edge is automatically controlled by detecting the gap continuously.
