Оправки имели одинаковый диаметр калибрующего участка. Прошивка осуществлялась при тем­пературе слитков 400 °С. Исследовано влияние формы оправки на изменение наружного диаметра и толщины стенки по длине гильзы, а также плотности гильзы по длине. Для измерения плотности гильз они были разрезаны на 15 равных по толщине колец, плотность которых определялась с помощью гидростатического взвешивания. Экспериментальные исследования смоделированы с помощью вычислительных сред конечно-элементного анализа. Получение слитка напол­нительным литьем моделировалось с помощью ProCAST, а прошивки — QForm. Путем компьютерного моделирования также оценивались изменения диаметра, толщины стенки и плотности гильз по длине. Проведено сравнение результатов экспериментальных исследований и компьютерного моделирования с целью оценки адекватности полученных моделей в QForm. Отличие данных по плотности не превышает 2 %, по размерам гильз — 20 %. Полученные результаты позволили установить влияние формы прошивной оправки на точность получаемых гильз и их плотность. С точки зрения точности размеров получаемых гильз наиболее предпочтительно использовать полую оправку или оправку с углублением. Каждая из рассмотренных схем прошивки позволяет уплотнить до истинной плотности весь объем гильзы, за исключением при- торцевых областей, где плотность ниже на 1 %.</p></abstract><trans-abstract xml:lang="en"><p>Mannesmann piercing of ingots, which were made of aluminum alloy by casting, was done using plugs of different shape: entire plug, plug with cavity and hollow plug. Plugs had same diameter of calibrating segment. Piercing was carried out at 400 °C ofbillets. Influence of plugs’ shape on variation of hollow shells’ diameter, wall thickness and density along their length was estimated. Hollow shells were cut into 15 equal rings to measure density using hydrostatic (Archimedean) weighing. Experimental operations were simulated using FEM computer software. Casting was simulated using ProCAST, piercing — using QForm. Variation of hollow shells’ diameter, wall thickness and density along their length was estimated after simulation had been done. Experimental and simulation data were compared to check FEM simulation accuracy. Difference between experiment and simulation for density was not more than 2 %, for hollow shells’ dimensions — 20 %. Conducted investigation allowed estimation of how plug’s shape affects hollow shells’ dimensions accuracy and density. It was established that hollow plug or plug with cavity, in terms of dimensions accuracy and density variation, are preferable for piercing. Each of plugs being used, provides manufacturing of hollow shells with maximum density for all volume except close to hollow shell’s edges domains, where density is 1 % less than maximum value.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наполнительное литье</kwd><kwd>ProCast</kwd><kwd>компьютерное моделирование</kwd><kwd>прошивка</kwd><kwd>винтовая прокатка</kwd><kwd>двухвал¬ковый стан</kwd><kwd>QForm</kwd><kwd>плотность</kwd><kwd>толщина стенки</kwd><kwd>диаметр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ingot casting</kwd><kwd>ProCAST</kwd><kwd>computer simulation</kwd><kwd>piercing</kwd><kwd>screw rolling</kwd><kwd>Mannesmann rolling mill</kwd><kwd>QForm</kwd><kwd>density</kwd><kwd>wall thickness</kwd><kwd>diameter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Erman E.
