Перспективным направлением с точки зрения снижения себестоимости производства наплавочных материалов и обеспечения их требуемых технологических свойств является разработка новых составов порошковых проволок и флюсов на основе техногенных металлургических отходов. Проведенными в рамках развития указанного направления экспериментальными исследованиями показана принципиальная возможность и эффективность использования барий-стронциевого карбонатита при изготовлении сварочных флюсов на основе ковшевых электросталеплавильных шлаков. При проведении лабораторных исследований по наплавке стальных образцов использовали барий- стронциевую флюс-добавку двух видов: смешанный с жидким стеклом барий-стронциевый модификатор и пыль барий-стронциевого модификатора фракции менее 0,2 мм. По полученным данным при использовании различных вариантов составов флюсов с варьированием доли вышеуказанных компонентов обеспечивается удовлетворительное качество макроструктуры наплавленного слоя и снижение загрязненности металла сварного шва такими неметаллическими включениями, как силикаты недеформирующиеся, оксиды точечные и силикаты хрупкие.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Analysis of existing methods to increase the stability of rolls calibers has shown that one of the most effective methods is surfacing with solid or powdered wires, which is confirmed by the numerous research materials of domestic and foreign authors on improving the compositions of powder wires and welding fluxes. A promising direction in terms of reducing the cost of surfacing materials production and ensuring their required technological properties is the development of new compositions of powder wires and fluxes based on man-made metallurgical wastes. Experimental studies carried out within the framework of the development of this direction show the principal possibility and effectiveness of the use of barium-strontium carbonatite in the manufacture of welding fluxes based on ladle electric-furnace slags. When conducting laboratory studies on surfacing of steel samples, a barium-strontium flux was used. An additive was prepared in two ways: a barium-strontium modifier mixed with liquid glass and a barium-strontium fraction modifier of less than 0.2  mm. According to the data obtained, when using different variants of flux compositions with varying proportions of the above components, a satisfactory quality of the deposited layer macrostructure is ensured and the contamination of the welded joint is reduced by such nonmetallic inclusions as silicates that are not deformed, point oxides and silicates are brittle.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наплавка</kwd><kwd>прокатные валки</kwd><kwd>сварочные флюсы</kwd><kwd>техногенные отходы</kwd><kwd>барий-стронциевый модификатор</kwd><kwd>электросталеплавильный шлак</kwd><kwd>микроструктура</kwd><kwd>неметаллические включения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surfacing</kwd><kwd>rolling rolls</kwd><kwd>welding fluxes</kwd><kwd>man-made waste</kwd><kwd>barium-strontium modifier</kwd><kwd>electric-furnace slag</kwd><kwd>microstructure</kwd><kwd>nonmetallic inclusions</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">Трайно А.И.
