A dynamic model of the cold rolling process at the continuous rolling mill that combines the model of the electromechanical system, the model of the deformation zone and the model of the hydraulic clamping device has been developed. The paper presents the results of the statistical evaluation of the accuracy of the model for uncertainty calculation of rolling force. The results showed that more than 93% of the cases the calculation error does not exceed 6 %, the maximum error of 16.6 %. The mathematical model ensures high accuracy of predicting the magnitude and nature of the change of rolling force with the consideration of non-stationarity and stochasticity of technological parameters. This research was financially supported by the Ministry of Education and Science of Russian Federation within the framework of the project part of state task of Cherepovets State University (№ 11.3943.2024/ПЧ). Key words: Cold rolling, non-steady process, stochasticity of parameters, deformation zone, electromechanical system.
