With the increasing standard of living in China, the demand for tinplate for the production of foodstuff cans andtins for other products is rising. Apart from sophisticated mechanical equipment and reliable processing line design, highly developed process technology and process components are required for the production of electrolytically tinned ultra-thin sheet.The main process steps to be performed during strip coating are pre-cleaning, tension leveling, electrolytic pickling,preconditioning, electrolytic tin coating as well as re-melting and passivation of the surface. Each of these steps must meet high requirements to ensure the demanded surface quality of the final material. In the electrolytic tinning lines of SMS Siemag soluble tin anodes are used, resulting in considerable economic advantages. For example, the reduced expenditure on the tin used and the continuously high surface quality and efficiency of the system without the need for edge masks. Moreover, there are no costs for restoring the anode surface and no oxygen is required for tin-dissolving. SMS Siemag offers also various innovative technologies for the electrolytic tinning process. For example, a preconditioning cell activates the strip and removes Fe-hydroxide right before the strip runs into the first tinning cell, which creates some benefits for the tinning process. Another example is an evaporator behind the tinning process, which recovers the tin out of the rinsing water. In this paper, the plant technology for electrolytic tinning lines with soluble anodes from SMS Siemag is presented. In this case, special emphasis is placed on the process components.
