The pickling process of the present invention is designed for pickling electrical steel strip in a continuous fashion and comprises at least one pickling tank equipped with at least one set of sprayers designed to spray the top and bottom surfaces of a steel strip with a solution comprised of hydrogen peroxide prior to and/or after the strip is immersed in a solution contained in a pickling tank. The set(s) of sprayers in each of the pickling tanks are located above the level of the pickle bath solution, rather than being located in separate spray tanks. Upon exiting the final pickling tank, the strip is brushed/scrubbed to loosen any residual scale to form a clean strip. |
