The paper presents the results of research on the effect of working roll peripheral speed asymmetry applied in the process of rolling feedstock being fed at an angle into the roll gap. The variable process parameters were: the working roll peripheral speed asymmetry ratio, roll gap strip feed angle, deformed strip temperature and the strip shape factor. The purpose of the research was to determine the optimal values of speed asymmetry ratios assuring a strip to be obtained, which would be either straight or having a small allowable curvature not hindering the introduction of the strip to
the subsequent pass. Tests were carried out for both the symmetric and the asymmetric rolling processes. The grade steel was used for the tests. The asymmetric rolling process was run by varying the rotational speed of the
upper roll, which was lower than that of the lower roll.
