Abstract
A method for controlling coating weight on a hot-dipped steel strip comprises the steps of positioning at least one pair of high-frequency (alternating) current conducting paths near one side of a steel strip and near another side of the steel strip drawn out of a coating bath, each of the high-frequency (alternating) current conducting paths being parallel with a surface of the steel strip above the coating bath, and flowing a-high-frequency (alternating) current strong enough to magnetically saturate the steel strip through the at least one pair of high-frequency (alternating) current conducting paths to induce a high-frequency (alternating) current of an opposite phase in the steel strip, a magnetic pressure acting on surfaces of the steel strip being generated by an interaction of the induced high-frequency (alternating) current with a high-frequency (alternating) current of the high-frequency (alternating) current conducting paths.
