(54) СПОСОБ ПРОИЗВОДСТВА ТРУБ(54) METHOD OF PIPE MANUFACTURE
1one
Изобретение относитс к производству гор чекатаных бесшовных труб на трубопрокатной установке с трехвалковым раскатным станом.The invention relates to the production of hot-rolled seamless pipes in a pipe-rolling plant with a three-roll mill.
в технической литературе известен р д способов, совершенствующих процесс раскатки труб на трехвалковом раскатном стане. Известен спосо производства труб, включающий прошивку , винтовую раскатку трем валками на длинной оправке и обкатку на короткой оправке l . Процесс обкатки примен ют дл снижени продольной и поперечной разностенности и он характеризуетс небольшими обжати ми .In technical literature, a number of methods are known that improve the process of pipe rolling on a three-roll rolling mill. Known method of pipe production, including firmware, screw rolling with three rollers on a long mandrel and run-in on a short mandrel l. The run-in process is used to reduce the longitudinal and transverse wall thickness, and it is characterized by small cuts.
Наиболее близким к описываемому изобретению по т ехнической сущности вл етс способ производства труб, включающий прошивку нагретой заготовки , винтовую раскатку гильзы рем валками на длинной оправке, дополнительную раскатку на той же оправке и калибровку 2 . Способ повышает точность труб, но не способствует расширению сортамента труб и не может существенно увеличить производительность трубопрокатной установки .The closest to the described invention in terms of its technical nature is the method of producing pipes, including flashing the heated billet, screw rolling the liner with rollers on a long mandrel, additional rolling on the same mandrel, and calibration 2. The method improves the accuracy of pipes, but does not contribute to the expansion of the range of pipes and can not significantly increase the performance of the pipe mill.

Целью изобретени вл етс расширение сортамента труб.The aim of the invention is to expand the pipe mix.
Цель достигаетс тем, что в способе производства труб, включающем прошивку нагретой заготовки, винтовую раскатку гильзы трем аалками на длинной оправке, винтовую дополнительную раскатку и калибровку, дополнительную винтовую раскатку гильзы ведут на короткой оправке с деформацией по совенке и наружному диаметру 5-15%. При этом соотношение деформации по толщине стенки винтовых раскаток гильз на короткой и длинной The goal is achieved by the fact that in the production method of pipes, which includes the firmware of the heated billet, screw rolling of the sleeve with three aals on a long mandrel, screw additional rolling and calibration, additional screw rolling of the sleeve is carried out on a short mandrel with a deformation of 5–15%. The ratio of deformation through the wall thickness of the screw roll sleeves for short and long
5 оправках составл ет 1: (1,2-20), а по наружному диаметру 1: (0,8-1,2).The 5 mandrels are 1: (1.2-20), and the outer diameter is 1: (0.8-1.2).
Винтова раскатка гильзы на короткой оправке не сдерживает производительность установки, так как Screw rolling of the sleeve on a short mandrel does not constrain the installation performance, since
0 невысока степень обжати по толщине стенки в, пределах 3-25% (при обжатии 30-60% на трехвалковом раскатном стане с длинной оправкой) позвол ет вести прокатку на углах подачи 0 low degree of reduction in wall thickness in the range of 3-25% (when compressing 30-60% on a three-roll rolling mill with a long mandrel) allows rolling on feed angles
5 8-12° (процесс прокатки на трехвалковом раскатном стане осуществл ют на углах подачи 4-8 ),5 8-12 ° (the rolling process on a three-roll rolling mill is carried out at feed angles 4-8),
Наличие операции винтовой раскатки труб на короткой конической оправке The operation of the screw rolling pipes on a short conical mandrel
