The present application describes a method for stripping a moving metal product (3) having a layer of oxides, using laser stripping, which comprises the following steps: at least a first laser (6) sends a beam (7) which is reflected on the oxidised surface of the product (3) to be stripped, said reflected beams (9) being intercepted by sensors (8) which send the information collected to a processing unit (10); a processing unit (10) calculates the absorption of the beam (7) by the surface of the product (3), deduces therefrom the emissivity of the oxidised surface in the direction of said reflected beams (9) and correlates this emissivity with reference information pre-recorded in said processing unit (10); at least a second laser (13) sends a beam (14) to the product surface in order to strip it, the spots of said beams (14) covering all of the surface to be stripped via an optical and/or mechanical scanning process that laterally moves the spots of the beams (14) on the surface of the product (3), or via an optical system that converts the spots into lines, said second laser (13) being operated by a control unit (15) receiving information provided by the processing unit (10) in order to determine the operating parameters to be applied to said second laser (13) for stripping the surface of the product (3), by comparing with experimental results pre-recorded in the control unit(15); and means (16, 17) of inspection of the stripped surface of the product (3) check the effectiveness of the stripping. The present application also describes a plant for executing this method.
