Analysis of Galvanized Steel Sheets Fabrication in Cold Rolling Shop and Identification of Local Impacts Contributing to Corrosion of Metal-Products

Abstract:

An urgent need has been identified, associated with the validity of improving the process for the manufacturing of galvanized steel, in the analysis and improvement of each stage of production in the conditions of the particular cold-rolled shop of the Iron and Steel Work. As a novelty, the processes and equipment for cleaning a hot-rolled strip, pickling a strip, rolling of pickled strips, physicochemical surface treatment, zinc coating, passivation, and other elements were reviewed from the point of view of possible corrosion consequences of the production. For the first time in the considered production system, elements and operations, their errors and imperfections, which can lead to poor-quality coating, violation of the zinc layer and reasons that contribute to the corrosion of galvanized metal products in the future, were identified at each stage.
