Physical simulation when students study theories and technologies of rolling

The article describes the training and research rolling mill DUO-130, designed and manufactured for educational and research organizations. The rolling mill developed by LLC RPE “Uchtekh-Profi” has the design features of typical rolling mills used in modern rolling production, which makes it in demand in the training of engineering personnel for metallurgical enterprises. Currently, these mills are used as training equipment in the following educational institutions: Nosov Magnitogorsk State Technical University, Volzhsky Polytechnic Institute (branch) of Volgograd State Technical University, Chelyabinsk State Industrial Humanitarian Technical School named after A.V. Yakovlev, Lipetsk Metallurgical College and others. An automated mill control system, a system for collecting, processing and storing digital information allows it to be used to study the rolling process for both educational and research purposes. On the example of physical modeling of the basic laws and regularities of the rolling process, the methodological aspects of the use of modern educational equipment in the educational process in universities and colleges in the study of the theory and technology of rolling are presented. The article presents the results of experimental studies of the law of volume constancy, the conditions for capturing metal by rolls, the patterns of advance and lag, broadening and the effect of the friction coefficient on these indicators. In subsequent publications, it is planned to consider the issues of studying the behavior of metal in calibers during section rolling, the rules for designing calibers and determining the causes of the formation of defects in section profiles. It is also planned to devote a separate publication to physical modeling and experimental determination of the energy-power parameters of rolling using the DUO-130 mill automation system, which allows not only determining the rolling force but also displaying and saving recorded values in files in the form of oscillograms, graphs, diagrams and arrays of data.
