Abstract
Способ получения бесшовных тонкостенных труб, включающий прошивку заготовки в гильзу в стане поперечно-винтовой прокатки на перемещаемой оправке при прошивке заднего конца заготовки в направлении, противоположном направлению прокатки, и последующую раскатку гильзы в валках с гребнем на трехвалковом раскатном стане поперечно-винтовой прокатки, отличающийся тем, что прошивку заднего конца ведут с обжатием стенки гильзы за счет увеличения внутреннего диаметра, составляющего от 0,8Δ до 1,7Δ и на длине от торца гильзы, составляющей от 21Δ до 28Δ, где Δ - обжатие перед гребнем валка трехвалкового раскатного стана.A method of producing seamless thin-walled pipes, including piercing a workpiece into a sleeve in a cross-helical rolling mill on a movable mandrel when flashing the rear end of the workpiece in the opposite direction of rolling, and subsequent rolling of the sleeve in rolls with a comb on a three-roll rolling mill of cross-helical rolling, characterized the fact that the rear end firmware is driven with compression of the sleeve wall due to an increase in the inner diameter of 0.8Δ to 1.7Δ and a length from the end of the sleeve of 21Δ to 28 Where Δ - reduction before the crest of the roll the Print three-roller mill.
