Abstract：The effects of the control of the speed optimization，the control of the looper level and the control of the tension on increasing the stability of mills and production rhythm，and improving the surface quality of strips are extremely important in continuous pickling process. Aiming at 1 740 mm continuous pickling line and tandem cold rolling mills，based on the principle of penalty function，the objective function model of speed was established to calculate the pickling speed. And consequently，the speed coordination and stability of continuous pickling process for high strength steels were guaranteed. Meanwhile，the synchronous control for the looper level was achieved through the control of the entry and exit speed of looper，to meet the requirement of the looper level and tension. The setup calculation model of the tension for continuous pickling process was built，and then the accuracy of the tension control and the response performance of the system were improved，which realized the coordination of pickling speed and the control of rolling rhythm. The application results showed that the setup model with high computational accuracy could make the surface quality and flatness quality of high strength steels after pickling significantly improved，in addition，the qualified product ratio of production of high strength steels was further increased. Therefore，the model was suitable for the practical production.
