Abstract: A continuous cleaning installation 1 of a passing strip S includes a tank 2, an aqueous solution 3 inside the tank 2. It also includes at least a roller 4 immerged in the aqueous solution 3, at least an ultrasound emitter-5, a feed for feeding 6 an aqueous solution and emptying 7 the tank. Moreover, it also includes an aqueous solution level estimator for estimating 8 the aqueous solution level, a distance calculator for calculating 9 for each ultrasound emitter 5 its distance to the aqueous solution level and a power controller for controlling the power 10 of the at least one ultrasound emitter 5 and at least an impermeable closable opening 11 on at least a lateral side of the tank through which the at least one ultrasound emitter 5 can pass.

Abstract: A method of treatment of a cutting piece (2) is provided. This method includes a first step in which a cutting surface (5) of this cutting piece (2) is subjected to shots thrown by an ultrasonic shot peening apparatus (10) to become a cutting surface (5) with shot impacts, and a second step in which the cutting surface (5) with shot impacts is grinded over a chosen thickness to become a treated cutting surface (5).

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.
