Development of Processing Technology for Flat Sheet Products

Over the last few decades, the production technology for flat sheet products has developed with the aim of producing products having higher quality, better functionality, and improved productivity. Of the many fruits of such development, this paper focuses first on the manufacture of deep-drawing sheets and high-tensile sheets through continuous annealing. Second, we address the production of highly corrosion-resistant sheets for automotive use through continuous hot-dip galvanizing. Finally, we determine measures to homogenize the coating weight of electrolytic tinplates and to enhance labor productivity.
