Изобретение относится к области прокатного производства и может быть использовано при горячей прокатке полос из углеродистых, низколегированных, легированных и коррозионно-стойких сталей. Способ включает формирование плоской заготовки со скругленными боковыми кромками регламентированной кривизны, сопряженными с ее плоскими гранями, и последующую горячую прокатку заготовки с суммарным относительным обжатием 90 - 99%. С целью увеличения выхода годного и повышения качества полос сопряжение скругленных кромок с плоскими гранями осуществляют по выпуклой криволинейной поверхности с величиной кривизны в 3,4 - 12,7 раза меньшей кривизны скругления боковых кромок. 1 с. п. ф-лы, 1 табл.The invention relates to the field of rolling production and can be used when hot rolling strips of carbon, low alloyed, alloyed and corrosion-resistant steels. The method includes the formation of a flat billet with rounded side edges of a regulated curvature, associated with its flat edges, and subsequent hot rolling of the billet with a total relative compression of 90-99%. In order to increase the yield and improve the quality of the bands, the mating of the rounded edges with flat edges is carried out on a convex curvilinear surface with a curvature of 3.4 - 12.7 times less than the curvature of the side edges. 1 sec. the item f., 1 tab.
