Abstract
Изобретение относится к обработке металлов давлением и может быть использовано для изготовления полосы. Холодную прокатку полосы в валках осуществляют при рассогласовании их окружных скоростей с единичной степенью деформации не менее 50%, причем прокатку ведут до суммарной степени деформации 75-95%. Одновременное повышение прочностных и пластических свойств на 5-10% с получением градиентной структуры металла обеспечивается за счет того, что прокатку осуществляют в валках разного диаметра, причем шероховатость первого валка Ra составляет 10,0-12,0 мкм, a Ra второго валка - 0,5-2,5 мкм, при этом окружная скорость валков регламентирована математической зависимостью.The invention relates to the processing of metals by pressure and can be used for the manufacture of strip. Cold rolling of the strip in rolls is carried out with a mismatch of their circumferential speeds with a unit deformation of at least 50%, and rolling is carried out to a total deformation of 75-95%. A simultaneous increase in strength and plastic properties by 5-10% with obtaining a gradient metal structure is ensured due to the fact that rolling is carried out in rolls of different diameters, and the roughness of the first roll Ra is 10.0-12.0 μm, and Ra of the second roll is 0 , 5-2.5 microns, while the circumferential speed of the rolls is regulated by a mathematical relationship.
