Abstract
An analysis of asymmetrical band rolling in the last two stands of a finishing sheet hot rolling mill has been performed in the study. Investigations were carried out to determine the range of values of roll peripheral speed asymmetry ratios which would assure the permissible bending of band upon its exit from the roll gap and to reduce the value of the overall metal pressure on the rolls without causing overloading of the drives of the finishing group of the continuous sheet rolling mill. The application of asymmetrical rolling on the last two stands has made it possible to reduce deviations in band thickness, decrease the minimum thickness of finished sheet from 2.00 mm to 1.80 mm and increase the width of sheets produced in the thickness range from 1.80 - 2.00 mm to above 925 mm.
