Abstract

Изобретение относится к обработке металлов давлением. Прокатку тонкой полосы осуществляют в двух рабочих валках с рассогласованием их скоростей. Повышение устойчивости процесса деформирования полосы и снижение усилия прокатки обеспечивается за счет того, что прокатку осуществляют с рассогласованием скоростей по меньшей мере в два раза с единичной степенью деформации не менее 50% до суммарной степени деформации 75-95%. При этом прокатку ведут с передним и задним натяжениями, причем заднее удельное натяжение задают равным 0,10-0,20 от предела текучести, а переднее удельное натяжение регламентировано математическими зависимостями.The invention relates to the processing of metals by pressure. The thin strip is rolled in two work rolls with a mismatch of their speeds. An increase in the stability of the strip deformation process and a decrease in the rolling force is ensured due to the fact that rolling is carried out with a speed mismatch of at least two times with a unit strain rate of at least 50% to a total strain rate of 75-95%. In this case, rolling is carried out with front and rear tensions, and the rear specific tension is set equal to 0.10-0.20 of the yield point, and the front specific tension is regulated by mathematical relationships.
