摘要： A method for the electrolytic tinning of steel strip in an electrolytic bath wherein the steel strip is the cathode and insoluble anodes are used, the electrodes are immersed in an electrolyte solution containing tin ions and wherein the concentration of the tin ions in the bath is controlled by passing the solution exterior of the bath in contact with tin in particulate form, while simultaneously maintaining a high content of dissolved oxygen in the solution. This latter treatment replenishes the tin concentration of the solution and the thus replenished electrolytic solution can be returned to the bath in a manner so as to consistently maintain the tin ion concentration at the desired level.

摘要： A surface-treated steel sheet is provided, at a low cost, which has high weldability and is useful for a material of containers of foods and beverages. The surface treatment is conducted by applying flattened granular tin coating deposits having a specified diameter and high adhesion on a steel sheet surface at a specified plated area ratio, and applying thereon a metallic chromium coating and a chromium hydrate oxide coating.In the surface treatment, firstly, the surface of a steel sheet is subjected to tin-plating in an acidic tin plating bath containing a conventionally used brightener in an amount of from 0,001 to 0.05 g/l so as to form flattened granular tin coating deposits having a diameter of 0.4-2.4 .mu. at a plated area ratio of 5 to 30% and to improve the adhesion to the steel sheet and decrease falling-off of the granular tin coating deposits until completion of chrome-plating, thereby the variation of the amount of tin coating being decreased. Subsequently, the sheet is plated with metallic chromium in an amount of 50-150 mg/m.sup.2, and further chromium hydrate oxide layer is formed in an amount of 2-40 mg/m.sup.2 as chromium. Thus a surface-treated steel sheet, which has satisfactory surface appearance, paint adhesiveness, under-paint-coating corrosion resistance of conventional tin-free steel sheets, and stable weldability, is producible at a low cost.
