Development and application of friction model for cold rolling control model

Friction model is one of the most important models in cold rolling. At present,a lot of researches focusing on it were carried out in the experimental environment. Based on the process principle of the classical friction model,considering the influence of the key factors such as roll roughness and rolling speed,a suitable friction model was proposed combining with the actual situation of production control and the overall design of the rolling model. Moreover,the debugging method of the key parameters of the friction model was briefly introduced,and a set of methods for indirectly evaluating the accuracy of the model was proposed. Through field test and long-term practical application,it was proved that the control effect of the model was excellent.
