Сегментный способ прокатки круглых профилей большого диаметра на реверсивных обжимных станах, отличающийся от существующих способов прокатки в системе калибров «предовал-овал-круг» тем, что для получения круглого профиля из заготовки прямоугольного сечения (блюмса) требуется только один калибр специальной формы, в котором при прокатке заготовки за один проход формируется два противоположных сегмента (по 90° каждый) округлой формы по сечению раската и после кантовки раската на 90° и повторного прохода заготовки через этот калибр формируется раскат круглого сечения.The segmented method of rolling round profiles of large diameter on reversible crimping mills, which differs from the existing methods of rolling in the pre-oval-circle gauge system in that only one caliber of a special form is required in order to obtain a round profile from a rectangular billet (bloom) in which when rolling a workpiece in one pass, two opposite segments (90 ° each) are formed in a rounded shape along the roll section and after turning the roll 90 ° and re-passing the workpiece through this gauge, tsya roll of circular cross-section.
