В качестве наиболее эффективного метода предложена технология ведения переплава на постоянном токе. Описание технологии затрагивает положительные и отрицательные эффекты, влияющие как на удельную производительность плавки, энергопотребление, так и на качество получаемых слитков в части их физико-механических свойств и химической чистоты. Способ ведения электрошлакового переплава с вращением расходуемого электрода предложен в качестве новой технологии, осуществлено краткое сравнение с используемой технологией наложения внешнего магнитного поля. Продемонстрированы схемы, которые наглядно показывают принцип управления формой фронта кристаллизации и локализацией теплового центра шлаковой ванны. Разработана стационарная численная модель для рабочей зоны действующей полупромышленной печи ЭШП А-550 на постоянном токе со сменой полярности. Создан математический аппарат, состоящий из электротермической, гидродинамической и конвективной частей. Геометрическая расчетная область спроектирована для шлаковой ванны, расположенной между расходуемым электродом и водоохлаждаемым кристаллизатором с диаметрами 60 и 90 мм соответственно. Высота подэлектродной зоны составляет 10 мм. Предельная величина тока 800 А, напряжение 46 В. Получены числовые поля распределения плотности тока и температуры в толще шлаковой ванны. Диапазон значений температуры располагается в пределах от 1400 до 2200 °С на периферийной и подэлектродной зонах шлаковой ванны соответственно. Приведена схема модернизации печи ЭШП за счет автоматизации механической части и перевода на постоянный ток.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes the problem of increasing the productivity of electroslag remelting (ESR) furnaces. The remelting technology on direct current is proposed as the most effective method. The description of the technology touches upon positive and negative effects affecting the specific productivity of smelting, energy consumption, and quality of the obtained ingots in terms of their physical and mechanical properties and chemical purity. The authors proposed the electroslag remelting method with rotation of the consumable electrode as a new technology, and realized a brief comparison with the external magnetic field application technology. The schemes that clearly demonstrate the principle of controlling the crystallization front shape and the thermal center localization in the slag bath are considered. A stationary numerical model for the slag bath of the operating semi-industrial furnace ESR A-550 on direct current with polarity reversing ability was developed. The mathematical apparatus consisting of electrothermal, hydrodynamic and convective parts was constructed. The authors designed the mesh domain for a slag bath located between the consumable electrode and the water-cooled crystallizer with diameters of 60 and 90 mm, respectively. The height of the sub-electrode zone is 10 mm. The current limit is 800 A and the voltage is 46 V. Numerical fields of current density and temperature distribution in the slag bath volume are obtained. The range of temperature values is located in the range from 1400 to 2200 °C at the peripheral and subelectrode zones of the slag bath, respectively. The scheme of the ESR furnace modernization is given in terms of mechanical part automation and transferring to direct current.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрошлаковый переплав</kwd><kwd>электротермия</kwd><kwd>расходуемый электрод</kwd><kwd>метод конечных объемов</kwd><kwd>вычислительная гидродинамика</kwd><kwd>компьютерное моделирование</kwd><kwd>математическое моделирование</kwd><kwd>технология</kwd><kwd>вращающийся электрод</kwd><kwd>постоянный ток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electroslag refining</kwd><kwd>electrothermy</kwd><kwd>consumable electrode</kwd><kwd>finite volume method</kwd><kwd>computational fluid dynamics</kwd><kwd>computer simulation</kwd><kwd>mathematical modeling</kwd><kwd>technology</kwd><kwd>rotating electrode</kwd><kwd>direct current</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет гранта Российского научного фонда № 22-29-20049, https://rscf.ru/project/22-29-20049/.</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation, grant No. 22-29-20049, https://rscf.ru/project/22-29-20049/.</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">Павлов В.А.
