Последние (концевые) слябы имеют дефект в виде отклонения размеров поперечного сечения от заданных значений. Это приводит к дополнительным потерям металла на последующих металлургических переделах и уменьшает стоимость товарной продукции. В известных исследованиях и публикациях рассматривается технология непрерывного литья в установившиеся периоды. Переходные периоды изучены мало, так как в данном случае отсутствуют простые и надежные методы исследования теплообмена слитка с окружающей средой. В работе рассматриваются причины возникновения разноширинности в концевых непрерывнолитых стальных слябах. Выполнено численное моделирование напряженно-деформированного состояния слитка после порезки его на мерные длины. Расчеты проводились для заготовок из углеродистых марок стали. Установлено, что несимметричное по длине заготовки тепловое поле может вызывать в ней напряжения, превышающие напряжения текучести в диапазоне температур 800 – 900 °С. Это обуславливает возможность появления остаточных деформаций и отклонения ширины заготовки от номинального значения. Сравнение расчетных и экспериментальных данных показывает, что отклонение размеров поперечного сечения слябов происходит по следующим основным причинам: режим охлаждения хвостовой части слитка не является оптимальным; существует значительный перепад температур по длине концевой заготовки. Для уменьшения разноширинности непрерывнолитых стальных слябов, отлитых в период окончания разливки, необходимо усовершенствование технологии их охлаждения.</p></abstract><trans-abstract xml:lang="en"><p>At casting of steel on CCM quality of all ingots is almost identicalby creating stable conditions of continuous casting. The fi nalslabs have a defect in the form of the cross-sectional dimensions - the deviation from the desired values. This leads to additional losses of metal in subsequent metallurgical redistribution and reduces the cost of commodity products. The prior studies and publications consider continuous casting technology in the established periods. Transition periods have been poorly studied because there are no simple and reliable methods of investigation of heat exchange of the ingot with the environment during these periods. This article discusses the causes of different widths of the fi nal continuously casted steel slabs. The numerical modeling of the stress-strain state of the ingot after cutting to length it was made. Calculations were performed for ingots made of carbon steel grades. It was established that the asymmetric in length billet thermal fi eld may cause it stress exceeding the yield stress in the temperature range 800 – 900 °C. This leads to the possibility of residual strain and defl ection width of the ingot from the nominal value. Comparison of calculated and experimental data showed that the deviation of the cross-sectional dimensions of slabs occurs for the following reasons:1. Cooling mode of the tail section of the ingot was not optimal.2. There was a signifi cant temperature gradient along the length ofthe end of the ingot.To reduce the different widths of continuously casted steel slabs during the end of the casting it is necessary to improve their cooling technology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>непрерывная разливка</kwd><kwd>слябы</kwd><kwd>высокие температуры</kwd><kwd>напряжения</kwd><kwd>деформации</kwd><kwd>геометрические размеры поперечного сечения</kwd><kwd>технология непрерывного литья</kwd><kwd>моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>continuous casting</kwd><kwd>slabs</kwd><kwd>high temperatures</kwd><kwd>stresses</kwd><kwd>deformations</kwd><kwd>geometrical dimensions of the cross section</kwd><kwd>process of continuous casting</kwd><kwd>computer simulation</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">Sladkoshteev V.T., Akhtyrskii V.I., Potanin R.V.
