Optimization of cold rolling mill process to improve productivity and Product Quality of steel - an overview

  Vivek Anil Vaidya

There are many advances on metal rolling technologies over the past half century, but due to intense global competition and the requirements for increasingly thinner, higher quality rolled metal products continue to force metal producers to seek new ways to outperform one another. The need to optimize cold rolling mill to achieve profitability, and the significant costs associated with capital upgrades, mean that the application of innovative rolling technologies presents the most attractive near term solution for many steel manufacturer to improve quality and productivity. Set-up generation or pass schedule is an important aspect in the operation of Single stand reversing and tandem cold rolling mills. It defines speeds and powers for the drives, stand reductions, roll forces and entry & exit tensions and % reduction in each pass for the cold mill control system. This paper focuses on the various optimization techniques used in cold rolling mill process to achieve productivity and Quality of steel through literature review. Various Process models for cold rolling mills have been intensively developed in the last years, hoping to increase quality of steel strip and productivity of rolling processes. Nevertheless, characteristics are only achieved using models sufficiently to be accurate and robust. The availability of accurate models is associated for cold rolling process parameter optimization, has been intensely explored in the literature.
