Abstract
Способ производства стальных полос, включающий формирование плоской заготовки со скругленными боковыми кромками регламентированной кривизны, по выпуклой криволинейной поверхности сопряженными с ее плоскими гранями, и последующую горячую прокатку заготовки в полосу с суммарным относительным обжатием не менее 90%, отличающийся тем, что заготовку формируют с кривизной сопрягающих поверхностей, в 3,4 - 12,7 раза меньшей кривизны скругления боковых кромок.A method for the production of steel strips, including the formation of a flat billet with rounded side edges of a regulated curvature, along a convex curved surface conjugated with its flat edges, and subsequent hot rolling of the billet into a strip with a total relative reduction of at least 90%, characterized in that the billet is formed with curvature mating surfaces, 3.4 - 12.7 times less curvature of the rounding of the side edges.
