Следствием этого является увеличение сложности и длительности предварительной подготовки данных, поступающих от датчиков и измерительных систем, для последующего математического и статистического анализа. Поэтому весьма важно и актуально разрабатывать новые и совершенствовать существующие методики автоматизированного процесса первичной подготовки данных. При разработке методик первичной подготовки данных следует учитывать, что точность и адекватность результатов последующего математического анализа определяются точностью и адекватностью используемых исходных данных. Параметры профиля поперечного сечения горячекатаных полос, такие как клиновидность, выпуклость, разнотолщинность, смещение выпуклости, прикромочная клиновидность, локальные утолщения и утонения полосы являются расчетными параметрами, т. е. вторичны по отношению к фактическим измерениям толщины полосы по длине и ширине горячекатаных полос. По мере совершенствования технологии в цехах холодной прокатки тонколистовой стали растет число сортаментных групп, для которых технологические режимы обработки горячекатаных полос, осуществляющихся на агрегатах холодной прокатки и отделки стальных полос, а также маршруты их обработки выбирают, исходя из фактических значений параметров профиля поперечного сечения. Целью является последующее снижение вероятности образования несоответствующей продукции и повышенного расхода металла. В статье приведен обзор общепринятых методов расчета параметров профиля поперечного сечения горячекатаной полосы и дана оценка точности и адекватности применения усредненных по длине полосы параметров.</p></abstract><trans-abstract xml:lang="en"><p>Increasing the level of automation of metallurgical units and the development of industrial information systems increases the number of p ters of production and technological processes available for analysis. The consequence is an increase in the complexity and duration of preliminary data preparation for subsequent mathematical and statistical analysis. It is therefore important to develop new and improve existing techniques for the automated process of primary data production. When developing methods of primary data preparation, it should be taken into account that accuracy and adequacy of results of subsequent mathematical analysis are determined by accuracy and adequacy of used initial data. The cross-sectional profile parameters of hot-rolled strips, such as wedge, convexity, thickness variation, displacement, wedge in near-rim zones, local thickenings and thinning of the strip are calculated parameters, i.e. secondary to actual strip thickness measurements over the length and width of hot-rolled strips. As technology is improved in cold rolling shops, the number of grade groups is increasing, for which technological modes of units and processing routes are selected. They are based on actual values of parameters of cross-section profile in order to further reduce the probability of formation of inappropriate products and increased metal consumption. The presented article provides an overview of conventional calculation methods for parameters of cross-section profile of hot-rolled strip and gives an assessment of accuracy and adequacy of application of the parameters averaged along strip length to the whole strip.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тонколистовая прокатка</kwd><kwd>профиль полосы</kwd><kwd>прикромочная клиновидность</kwd><kwd>вероятность обрыва</kwd><kwd>предсказательный интервал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thin-sheet rolling</kwd><kwd>strip profile</kwd><kwd>edge wedge</kwd><kwd>probability of break</kwd><kwd>predictive interval</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-38-90257.</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Russian Foundation for Basic Research within the framework of scientific project No. 19-38-90257.</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">Ginzburg V.B.
