“…First, the incoming material composition in hot rolling will affect the composition of compounds in the strip steel, and further affect the hardness of the strip steel. Then, in the hot rolling process, the difference in the hot rolling process will also have a great impact on the deformation resistance of the hot-rolled finished strip, among which the final rolling temperature and coiling temperature have a great impact [6]. The difference in strip deformation resistance caused by hot rolling will be reflected in the cold rolling process.…”

“…Considering the elastic compression and recovery of the rolled piece, using the measured rolling force in the rolling force formula is necessary to correct the roll radius and external friction coefficient after flattening. The modified model can be described as follows (6): where Q F denotes the external friction coefficient. R ′ refers to the flattened radius of the roller, unit mm.…”

In view of the influence of the fluctuation of incoming material composition, finishing temperature and coiling temperature on the deformation resistance in the cold rolling process during the hot rolling process, the optimization objective function is established by combining the analytic method and big data regression. Further, the relevant characteristic coefficients are calculated through a large number of on-site actual data, and the deformation resistance model of hot-rolled finished strip and the rolling pressure prediction model of cold rolling process are obtained. Through the field test, the deviation between the predicted rolling force and the actual rolling force is less than 2%, and the accuracy of the model can meet the engineering requirements. More importantly, after using the research results described in this paper, the quality of cold rolled strip shape has been significantly improved, which can greatly improve the economic efficiency and market competitiveness of enterprises.
