The double cold reduction (DCR) process of ultra-thin plate rolling, which is seldom based on the model calculation is generally carried out by manual input rolling instruction parameters. The L2 process control model plays an important role in any process control system. In this paper, the DCR process control of continuous annealing is taken as the study object, and the control principle and function of each control module in L2 control models are studied, and the significance of L2 model to process control and technology application is analyzed. Some suggestions for the improvement of the control model application are proposed, which can provide effective guidance for the high automatic control of the double cold reduction of the ultra-thin strip steel.
