Abstract
The present invention provides a method of cleaning steel sheet, said method of cleaning steel sheet feeding a cleaning solution activated by ultrasonic waves of a frequency of 0.8 MHz to 3 MHz to a surface of steel sheet at an angle inclined by 1 to 80° with respect to a line perpendicular to the surface of the steel sheet in a direction opposite to the running direction, thereby enabling megasonic waves to be applied to cleaning of running steel sheet and improving the cleaning effect and cleaning speed, and a continuous cleaning system of steel sheet.
