Параметры истинного очага деформации определяются совокупностью факторов: калибровкой инструментов деформации и их позиционированием в очаге деформации, формой контактной поверхности, условиями протекания процесса (в особенности в неустановившейся его стадии) и т. д. Вследствие этого, точно определить параметры истинного очага деформации, опираясь лишь на геометрическое представление очага деформации, достаточно сложно. Указанные трудности аналитического описания характера формоизменения металла в очаге деформации не позволяют с высокой точностью определить ширину контактной поверхности по фактической геометрии очага деформации, а вместе с ней и площадь контактной поверхности, а следовательно – оценить энергосиловые параметры процесса. В работе проводились исследования процесса поперечно-винтовой прошивки заготовки с применением метода конечно-элементного (МКЭ) моделирования с целью корректировки расчетных параметров геометрического очага деформации для оценки энергосиловых параметров процесса. В статье представлены результаты применения методики оценки формоизменения заготовки при поперечно-винтовой прошивке с применением программы МКЭ моделирования. Методика позволяет учитывать сложный характер течения металла в очаге деформации и корректировать расчетные параметры для оценки энергосиловых параметров процесса. Результаты расчетов показали сходимость значений моментов прокатки с графиком момента прокатки, полученного с пульта управления прошивным станом в ТПЦ-1 АО «Северский трубный завод» при прошивке заготовки диаметром 360 мм в гильзу размером D×S = 433×26 мм из стали марки Д.</p></abstract><trans-abstract xml:lang="en"><p>Improving the process of billets piercing on helical rolling mills is closely related to the study of the nature of metal forming in deformation zone. The parameters of true deformation zone are determined by a combination of factors: calibration of the deformation tools and their positioning in the deformation zone, shape of the contact surface, the process conditions (especially in its unsteady stage), etc. As a result, it is quite difficult to accurately determine these parameters relying only on geometric representation of the deformation zone. These difficulties in the analy­tical description of the nature of metal forming in the deformation zone do not allow one to accurately determine the contact surface width from the actual geometry of the deformation zone, and with it the area of the contact surface, and therefore to estimate the process energy–power parameters. The work involved studying the billet helical piercing using FEM (finite-element method) modeling of the process in order to adjust the calculated parameters of the geometric deformation zone and to assess the energy-power parameters. The paper presents the results of the method application for assessing the billet forming during helical piercing using the FEM modeling software. This method makes it possible to take into account the complex nature of the metal flow in the deformation zone and to adjust the calculated parameters for estimation of the process energy-power parameters. The calculation results showed the convergence of the values of the rolling moments with the graph of the rolling moment obtained from the control panel of the piercing mill in the pipe rolling shop No. 1 of JSC Seversky Pipe Plant when piercing 360 mm diameter billets into a sleeve measuring D×S = 433×26 mm made of steel grade D.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поперечно-винтовая прошивка</kwd><kwd>формоизменение при винтовой прокатке</kwd><kwd>геометрия очага деформации</kwd><kwd>ширина контактной поверхности</kwd><kwd>площадь контактной поверхности</kwd><kwd>точность гильз</kwd><kwd>компьютерное моделирование процессов</kwd><kwd>энергосиловые параметры процесса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>helical piercing</kwd><kwd>forming during helical rolling</kwd><kwd>geometry of deformation</kwd><kwd>contact surface width</kwd><kwd>contact surface area</kwd><kwd>accuracy of sleeves</kwd><kwd>process computer simulation</kwd><kwd>energy-power parameters</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ (тема № FEUZ-2026-0013).</funding-statement><funding-statement xml:lang="en">The work was supported by the Ministry of Science and Higher Education of the Russian Federation (topic No. FEUZ-2026-0013).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Потапов И.Н.
