Abstract

FIELD: pipe and tube mills. SUBSTANCE: according to method, blank heated to rolling temperature is subjected to plastic flow in piercing press to obtain a hollow press blank which is then subjected to gauge reduction by means of helical rolling mill with the use of internal tool. Simultaneously blank undergoes drawing, and finally drawn hollow blank without bottom is subjected to plastic flow operation by means of pilgrim mill for producing a hot pilgrim milled pipe. Press blank without bottom is subjected by deformation by introducing it into spiral mill by that end which earlier had bottom as viewed in direction of milling. Before inserting a hollow blank into pilgrim mill, it is turned through 180 C. EFFECT: high efficiency.

Предложен способ изготовления бесшовных труб с помощью поперечно-винтовой и пильгерной прокатки, в котором заготовку, нагретую до температуры прокатки, пластически деформируют в прошивочном прессе с получением полой прессовой заготовки и затем обжимают по толщине стенки с помощью стана поперечно-винтовой прокатки с использованием внутреннего инструмента, при этом подвергают ее вытяжке. Затем вытянутую полую заготовку без дна подвергают пластической деформации с помощью пильгерного стана с получением трубы горячим пильгерованием. Прессовую заготовку без дна подвергают деформации, вводя в стан поперечно-винтовой прокатки тем торцом, где раньше было дно, если смотреть в направлении прокатки, и перед вводом полой заготовки в пильгерный стан ее поворачивают на 180o.A method for manufacturing seamless pipes using transverse helical and pilger rolling is proposed, in which a billet heated to a rolling temperature is plastically deformed in a piercing press to obtain a hollow billet and then crimped along the wall thickness using a cross-helical rolling mill using an internal tool while exposing it to a hood. Then the elongated hollow billet without a bottom is subjected to plastic deformation using a pilger mill to obtain a pipe with hot pilger. The billet without a bottom is subjected to deformation by introducing it into the cross-helical rolling mill with that end where the bottom used to be when viewed in the rolling direction, and before entering the hollow billet into the pilger mill, it is rotated 180 ° .
