Обоснована актуальность определения температурных полей и термоупругих напряжений в калиброванных бойках с буртами при формировании нескольких сортовых заготовок при обжатии сляба и на холостом ходу при охлаждении бойков водой. Приведены прочностные и теплофизические свойства стали, из которой изготовлены бойки. Показана геометрия бойка с буртами для получения трех сортовых заготовок за один проход. Приведены исходные данные для расчета температурного поля бойка с буртами установки совмещенного процесса при получении сортовых заготовок. Представлены температурные граничные условия для расчета температурных полей бойков с буртами. Описаны граничные условия для определения температуры бойка с буртами и приведены значения теплового потока и эффективного коэффициента теплоотдачи. Результаты расчета температурных полей выполнены в четырех сечениях и приведены для характерных линий и точек, расположенных на контактной поверхности бойка с выступами и в приконтактном слое на глубине 5 мм от рабочей поверхности. Приведены размеры сетки конечных элементов, которая использована при расчете температурного поля бойков с буртами. Температурное поле бойков с буртами определено на основе решения уравнения нестационарной теплопроводности с соответствующими начальными и граничными условиями. Представлены величины и закономерности распределения температуры в основаниях и в вершинах среднего и крайнего буртов калиброванного бойка при обжатии сляба и на холостом ходу при получении за один проход трех сортовых заготовок на установке совмещенного процесса непрерывного литья и деформации.</p></abstract><trans-abstract xml:lang="en"><p>The article describes the main loads affecting shaped backups of the unit of combined process of continuous casting and deformation in billets production. Importance of determining the temperature fields and thermoelastic stresses in shaped backups with collars is provided at formation of several billets, at slab compression and at idle during water cooling of backups. The authors describe strength and thermophysical properties of steel from which the backups are made. Geometry of backups with collars used for obtaining billets of three different shapes in one pass is shown. Initial data of the temperature field calculation are given for backups with collars of the combined unit. Temperature boundary conditions are considered for calculation of temperature fields of backups with collars. Boundary conditions determining temperature of such backups are described and values of the heat flow and effective heat transfer coefficient are given. The results of calculation of temperature fields are performed in four sections and are given for typical lines and points located on contact surface of backups with collars and in contact layer at depth of 5 mm from the working surface. The sizes of finite elements grid which is used at calculation of temperature field of backups with collars are provided. Temperature field of backups with collars is determined on the basis of solution of unsteady thermal conductivity equation corresponding initial and boundary conditions. Values and regularities of temperature distribution in bases and in tops of the middle and extreme edges of the shaped backups are presented during slab compression and at idle when obtaining billets of three shapes in one pass at the unit of combined continuous casting and deformation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>установка совмещенного процесса</kwd><kwd>кристаллизатор</kwd><kwd>сляб</kwd><kwd>сортовая заготовка</kwd><kwd>разделение</kwd><kwd>температурное поле</kwd><kwd>конечный элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>unit of combined process</kwd><kwd>crystallizer</kwd><kwd>slab</kwd><kwd>shaped billet</kwd><kwd>separation</kwd><kwd>temperature field</kwd><kwd>finite element</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">Лехов О.С., Михалев А.В.
