Работа посвящена решению проблемы создания системы нагрева полосы движущегося металла атакующими струями нейтрального газа путем оценки интенсивности нагрева полосы металла при помощи методов математического моделирования. Дано описание дифференциальной задачи теплопроводности и ее последующее упрощение с учетом сделанных допущений для получения эффективного расчетного алгоритма. Приведены эмпирические соотношения, выбранные для расчета локальных и средних значений коэффициентов теплоотдачи, а также базовые параметры для вариантных расчетов. Для сравнительного моделирования рассматривался участок длиной 20 м, на котором происходит нагрев полосы, входящей с температурой 500 °С, нейтральным газом с температурой 800 °С. Представлены результаты расчета зависимости средней по сечению температуры полосы от скорости ее движения (в диапазоне от 0,1 до 2 м/с) при двух значениях скорости истечения газа (20 и 40 м/с). На их основании авторы делают выводы о том, что только при малых скоростях движения полосы достигается приемлемая интенсивность нагрева, а также что скорость истечения газа (в рассмотренном диапазоне) не является резервом для существенного увеличения этой интенсивности.</p></abstract><trans-abstract xml:lang="en"><p>The authors investigated the intensity of heating of a moving strip of thermally thin metal on a finite length section by a system of attacking neutral gas jets. The article is devoted to solving the problem of creating a system for heating a strip of moving metal by attacking jets of neutral gas by estimating the intensity of heating a metal strip using mathematical modeling methods. The main options for heat treatment of sheet metal are named. The article describes the differential heat conduction problem and its subsequent simplification, considering the assumptions made to obtain an effective calculation algorithm; the empirical relations selected for calculating local and average values of heat transfer coefficients; and the basic parameters for variant calculations. For comparative modeling, a 20m-long section was considered, where a strip entering with a temperature of 500 °С is heated by neutral gas with temperature of 800 °С. The results of calculating the dependence of average cross-sectional temperature of the strip on its movement speed (in the range from 0.1 m/s to 2 m/s) at two values of the gas flow velocity (20 m/s and 40 m/s) are presented, on the basis of which the authors concluded that acceptable heating intensity is achieved only at low speeds of the strip, and the gas flow rate (in the considered range) is not a reserve for a significant increase in this intensity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическое моделирование</kwd><kwd>нагрев движущейся полосы металла</kwd><kwd>термически тонкое тело</kwd><kwd>струйный нагрев</kwd><kwd>атакующие струи</kwd><kwd>локальный коэффициент теплоотдачи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical modeling</kwd><kwd>heating of a strip of moving metal</kwd><kwd>thermally thin body</kwd><kwd>jet heating</kwd><kwd>attacking jets</kwd><kwd>local heat transfer coefficient</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">Асцатуров В.Н., Краснокутский П.Г., Берковская П.С.
