<p>Provided are a steel sheet rinsing method for rinsing a running steel sheet, and a steel sheet continuous rinsing apparatus. A rinsing liquid, to which ultrasonic waves of a frequency of 0.8 MHz to 3 MHz are applied, is fed at such an angle to the steel sheet surface by a shower method or a curtain flow method as is inclined oppositely of the running direction by 1 to 80 degrees with respect to the line normal to the steel sheet surface. As a result, mega-sonic ultrasonic waves can be applied to the rising operation of the running steel sheet, thereby to improve the rinsing effect and the rinsing rate.</p> |
