One of the local tasks of the “Cold Rolling Mill - Strip” system digital twin is the tension value choice in order to obtain a given quality strip with the required productivity. Taking into account non-distinct effect of tension on rolling process, the inter-stand tensions choice is a problem of multicriteria optimization with complicated on-line operation of digital twin. The relationships between tension level and technological parameters were obtained; they reflect well-known positive operating experience of different cold-rolling mills. Previously chosen tensions are assessed (taking into account restrictions of rolls retarding, strip bursting and non-flatness, and recommended based on the “tension level” characteristic. As a result of research on existing mills, dependencies were obtained to determine the rational values of the level of inter-stand tensions. An algorithm has been developed for assessing the cold rolling stability with allowance for tension. It allows to develop power-efficient technologies for production of cold-rolled strip with improved surface quality.
