A characteristic feature of the regime are obtained almost the same reduction ratio of the web  and flanges  during rolling in every universal groove: the difference values  and  are 0,4-2,4%, ie uniform deformation of the metal is achieved along the profile elements, which contributes to a high quality I-beam.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>двутавровый профиль</kwd><kwd>прокатка</kwd><kwd>рельсобалочный стан</kwd><kwd>группа тандем</kwd><kwd>математическая модель</kwd><kwd>корреляционно-регрессионный анализ</kwd><kwd>статистическое обобщение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>H-beam</kwd><kwd>double-T section</kwd><kwd>rolling</kwd><kwd>rail-beam mill</kwd><kwd>tandem group</kwd><kwd>mathematical model</kwd><kwd>correlation and regression analysis</kwd><kwd>statistical generalization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ФГАОУ ВПО "Уральский федеральный университет им. первого Президента России Б.Н.
