摘要：PURPOSE:To remove the scales on the surface of a band stainless steel with an excellent capacity and to clean the surface by anodizing a cold-rolled and annealed band stainless steel in an aq. NaCl soln., and then pickling the steel with sulfuric-hydrofluoric acid and nitric-hydrofluoric acid. CONSTITUTION:The cold-rolled and then annealed band stainless steel 1 is pasd through an electrolytic cell 2 filled with an electrolyte contg. 50-200g/l of NaCl and kept at 20-80 deg.C, then pasd between anode plates 3 and 3 and between cathode plates 4 and 4, and anodized to mostly dissolve and remove the scales on the surface in the electrolyte. The product of the current density and electrolyzing time in the anodization is controlled to 200-800A, c/cm<2>. The steel is then pasd through a brush roll 12, the inside of a first pickling tank 10, and a pickling soln. contg. 150-250g/l sulfuric acid and 5-50g/l hydrofluoric acid and kept at 70-90 deg.C. The steel is then introduced into a cond pickling tank 11 through a brush roll 12, pasd through the pickling soln. contg. 50-100g/l nitric acid and 5-50g/l hydrofluoric acid and kept at 50-70 deg.C to completely remove the remaining scales and to dissolve the ba metal immediately under the scales, and the surface is cleaned.
