چکیده انگلیسی
The strip deformation resistance is an important factor for tandem cold mill control. The experiment data of strip yield stress measured in the laboratory cannot satisfy the requirement of accuracy for tandem cold mill online control. In this paper, an adaptive calculation method for improving accuracy of strip deformation resistance model is built up. Using measured rolling force of online control, the inverse calculation method of deformation resistance is conducted for tandem cold mill control. The adaptive learning coefficients of deformation resistance model can be determined with exponential smoothing. The deformation resistance model and Bland-Ford-Hill rolling force formula are used for the calculation. The influences of plastic deformation zone, entry and exit elastic deformation zones in the roll bite on metal deformation resistance are considered in the models. The practical application verifies that the accuracy and stability of calculated results can satisfy well the need of online process control of tandem cold mill.
