Abstract: Introduces briefly process parameters, mechanical parameters and configuration of key sensors of the new 1700 mm 5-stand cold-rolling mill with pickling line in Tangsteel. Investigates mainly the core function of the TCM automation control software package involving the CORUM^TM physical process model based on neural network and cost functions and the advanced high accuracy/response and multi-variable closed-loop system to control workpiece gauge, tension and flatness. The practical application results show that the preset based on the advanced process model in combination with online closed-loop control can ensure the strip quality so as to provide the accurate gauge and flatness of finished products.
