Abstract

Заявленное изобретение относится к валку (26) для прокатки длинномерных изделий (18). Валок, вращаемый вокруг оси вращения (r), включает паз (44) для образования расчетной дуги (h) внешнего профиля заготовки и плоскость паза (тт), которая пересекает перпендикулярно оси вращения валок вдоль его меньшего сечения. Валок ассиметричен относительно плоскости паза (тт). Заявленное изобретение также относится к прокатной станции (22) и непрерывному прокатному стану (20), которые включают множество упомянутых валков. Наконец, заявленное изобретение относится к способу восстановления упомянутых валков.
