摘要 The rolling force model is the basis for reasonable selection of rolling equipment and optimization of rolling process, and the establishment of an accurate mathematical model as well as doing the corresponding parameter analysis has been the focus of research in this field for many years. Different modeling methods of the rolling force and their research progress were introduced, the main methods of which are the theoretical analysis, the finite element simulation, the artificial neural network modeling, the hybrid modeling of theory and neural network, as well as the hybrid modeling of finite element and neural network. Meanwhile, the application examples of rolling force models in thickness control, strip crown control, and schedule optimization were presented, and an outlook on the new directions of future development was made, including establishing new type of hybrid models, solving the black box problem, and realizing the multi-objective optimization accounting for some special requirements.
