In order to improve the quality of cold rolling products,an automatic control system for cold rolling is independently developed by National Engineering Research Center for Advanced Rolling Technology of University of Science and Technology Beijing. The multi-target load distribution model, the mathematical model of various deformation resistance, the decoupling compensation strategy for shape/thickness step-by-step calculation, the self-learning model of deformation resistance, etc. are integrated in the L2 system,which uses a process control platform,to achieve the mathematical model of the high precision cold rolling and the self-optimizing system. The dynamic reduction technology for ultra thin products, the roll core eccentricity compensation technology, the shape/thickness decou-pling control strategy,etc. are integrated in the L1 system to achieve stable and high precision rolling of thin strips. The application results show that these new technologies are fully qualified for the stable production of 0. 2 mm cold rolling strips,the thickness deviation is controlled within ± 2μm,and the yield and quality of products are greatly improved.
