| Abstract: | The main technical problems in the industrial production of ultra-thin and wide high quality cold rolled strip were analyzed. The key technologies for ultra-thin and of wide cold rolled strip were introduced from the aspects of dynamic optimization ofemulsion flow, gas mist mixing and oil-water mixing rolling lubrication system, shape quality control, coiling and uncoiling process, etc. The high-efficiency and stable plate pass control technology of ultra-thin wide strip continuous annealing process were briefly described from the aspects of deviation prediction and control and furnace roll shape optimization, and the key technologies of ultra-thin coating of ultra-thin and wide strip were described from the aspects of ultra-thin and coating control and characterization and prolongation of bath and anode life. Finally, the field application of the technology was described, and the development prospect of ultra-thin wide high quality cold rolled strip was prospected. |
