Review of experimental laboratory and industrial studies of asymmetric sheet rolling

A review and analysis of works describing the experience of laboratory and industrial studies of asymmetric sheet rolling have been carried out. The main methods of asymmetric sheet rolling are given, which make it possible to obtain a product with improved properties as compared to the traditional rolling method. It was established that almost all the authors of existing studies on laboratory and industrial testing of asymmetric sheet rolling claimed about improving the microstructure of rolled products, increasing its mechanical characteristics and reducing rolling forces. However, when organizing and implementing the asymmetric rolling technology at existing rolling mills, attention should be paid to the design features and technical capabilities of the rolling mills’ drive systems in terms of ensuring the stable implementation of the technological process in conditions of differing speeds of the upper and lower working rollers, as well as speed alignment when using rollers of different diameters. This is especially true for group drive systems, when the upper and lower rollers are driven by a single motor.
