Технология электрошлакового переплава с вращением расходуемого электрода вокруг собственной оси ведет к образованию восходящего потока тепла в шлаковой ванне, делая гидродинамическую обстановку в кристаллизаторе более рациональной с точки зрения использовании образующегося тепла. При вращении расходуемого электрода на пленку жидкого металла, образующуюся на торце электрода, действуют центробежные силы, которые беспечивают радиальное течение капель расплавленного металла. Последующий отрыв происходит с внешнего периметра электрода. Таким образом, капли электродного металла попадают в металлическую ванну ближе к стенке кристаллизатора, выравнивая температурный фронт ванны. Уменьшение температурного градиента ванны по сечению приводит к более плоскому фронту кристаллизации. Исследуемая технология электрошлакового переплава с  вращением расходуемого электрода должна оказывать влияние на физико-механические свойства получаемого слитка (заготовки). С целью установления влияния вращения расходуемого электрода при электрошлаковом переплаве на свойства получаемого металла были проведены экспериментальные переплавы. Представлены данные об экспериментальных электрошлаковых переплавах электродов марки стали 20Х13 по различным технологиям на установке А-550. В ходе эксперимента устанавливалось влияние технологии вращения расходуемого электрода на условия процесса переплава, кристаллизации слитка, изменение механических и физических свойств. Проанализировано влияние способа переплава на свойства получаемого слитка. В качестве основного инструмента исследования использована обработка полученных данных о  микротвердости, плотности, размере дендритной ячейки экспериментальных образцов. Анализ результатов исследований слитков в поперечном направлении показал повышение равномерности микротвердости при реализации технологии электрошлакового переплава с  вращением расходуемого электрода по ходу плавки. Также показано, что применение технологии вращения уменьшает размер дендритной ячейки отливки и повышает плотность формируемой заготовки в сравнении с классической технологией без вращения электрода.</p></abstract><trans-abstract xml:lang="en"><p>The article presents theoretical substantiation of the influence of electroslag remelting technology with rotation of consumable electrode on physicomechanical properties of the formed casting (billet). The technology of electroslag remelting with rotation of consumable electrode around its own axis leads to formation of upward flow of heat in the slag bath, making hydrodynamic environment in mold more rational from the point of using generated heat. During rotation of consumable electrode, centrifugal forces act on liquid metal film formed at the end of the electrode, providing radial flow of molten metal droplets. Subsequent separation occurs from the outer perimeter of electrode. Thus, drops of electrode metal fall into the metal bath closer to the wall of the mold, aligning temperature front of the bath. Decrease in temperature gradient of bath over the cross section leads to a flatter crystallization front. Studied technology of electroslag remelting with rotation of consumable electrode should have an impact on physical and mechanical properties of resulting casting (billet). In order to establish effect of rotation of consumable electrode during electroslag remelting on properties of metal obtained, experimental remelting was carried out. The article presents data on experimental electroslag remelting of electrodes of 20Kh13 grade steel using various technologies at A-550 unit. In course of experiment, influence of rotation technology of consumable electrode on conditions of remelting process, billet crystallization, changes in mechanical and physical properties was established. The influence of remelting method on complex properties of resulting billet was analyzed. As the main research tool, processing of the obtained data on microhardness, density, dendritic cell size of experimental samples was used. Analysis of the research results of billets in transverse direction showed an increase in microhardness uniformity in implementation of electroslag remelting technology with rotation of consumable electrode along the course of smelting. It is also shown that use of the rotation technology reduces size of dendritic cell of billet and increases density of the ingot formed in comparison with traditional technology without rotating electrode.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрошлаковый переплав</kwd><kwd>вращение электрода</kwd><kwd>микротвердость</kwd><kwd>дендритная ячейка</kwd><kwd>анизотропия свойств</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electroslag remelting</kwd><kwd>electrode rotation</kwd><kwd>microhardness</kwd><kwd>dendrite cell</kwd><kwd>anisotropy of properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа проведена в рамках выполнения гранта Президента РФ по договору № 14.Y30.18.2874-МК</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">Медовар Б.И., Цыкуленко А.К., Богаченко А.Г. и др.
