Abstract

Steel sheet pretreatment procedure for single-layer enameling, where the sheets after electrolytic degreasing and pickling are galvanically nickel-plated and then endowed with a water-soluble protective layer of a polyphosphate and/or an organic polymer, film former; characterized in that the electrolytic pickling is carried out with a current intensity of 20 to 40 amps/dm2 in an acid solution containing sulfate and/or phosphate, at temperatures of 40 to 80ºC, for about 0.2 to 3 minutes.
