Abstract

FIELD: rolled tube production, particularly manufacture of seamless hot rolled tubes by helical rolling. SUBSTANCE: at rolling tubes in helical rolling mill sleeve-type blank is used. Said blank has wall thickened near its bottom and leading end with variable diameter. Blank is deformed on held mandrel at least in two passes for achieving ratio of tube diameter to its thickness consisting 15-25. It is advisable to use as blank waste bodies of shells. EFFECT: enhanced efficiency. 2 cl

Изобретение относится к трубопрокатному производству и может быть использовано при производстве бесшовных горячекатаных труб винтовой прокаткой. При прокатке на стане винтовой прокатки используют стакановидную заготовку с утолщенной стенкой к дну и передним концом переменного диаметра. Заготовку деформируют на удерживаемой оправке не менее чем за два прохода до достижения отношения диаметра трубы к толщине ее стенки в пределах 15 - 25. В качестве заготовки целесообразно использователь утилизированные корпуса снарядов.The invention relates to pipe rolling production and can be used in the production of seamless hot rolled tubes by screw rolling. When rolling on a helical rolling mill, a glass-like billet is used with a thickened wall to the bottom and the front end of a variable diameter. The workpiece is deformed on the held mandrel for at least two passes until the ratio of the pipe diameter to the thickness of its wall reaches 15–25. It is advisable to use disposed shell shells as the workpiece.
