Abstract
Изобретение относится к способу изготовления бесшовного полого изделия из массивного стального круглого слитка, диаметр которого составляет <95% диаметра слитка, на двухвалковом стане поперечно-винтовой прокатки с помощью удерживаемой между косыми валками, имеющей прошивную часть и по меньшей мере одну прогладочную часть оправки с использованием калибровочных направляющих или на трехвалковом стане поперечно-винтовой прокатки с помощью удерживаемой между косыми валками, имеющей прошивную часть и по меньшей мере одну прогладочную часть оправки, причем определенным образом установлено расстояние между валками в самом узком сечении по отношению к диаметру слитка, а положение оправки - по отношению к самому узкому сечению валков.
