Ultrasound degreasing management

Abstract

A method for continuously cleaning a moving strip in a cleaning installation including a tank containing an aqueous solution, at least a roll immerged in the aqueous solution for guiding the strip into the tank, at least an ultrasound emitter a feed for feeding an aqueous solution inside the tank, a tank emptier for emptying the tank, an aqueous solution estimator for estimating the aqueous solution level in the tank, a distance calculator for calculating, for each ultrasound emitter, its distance to the aqueous solution level and a power controller for controlling the power of the at least one ultrasound emitter including the following steps, performed continuously: —estimating the aqueous solution level in the tank, —calculating for each ultrasound emitter its distance to the aqueous solution level, —comparing for each ultrasound emitter its distance to the aqueous solution level to a determined threshold.
