With the natural logarithm applied to the division of layers of thickness, the division of deformation resistance parameters is carried out according to different layers of thickness to solve the self-learning of rolling force. Then, the method of exponential smoothing is introduced into the model to deal with the deformation resistance parameters of each and every layer of thickness.
