Разработана эффективная технология силикотермического получения ферросиликобора, содержащего 0,6  ‒  2,0  %  B и 60  ‒  80  %  Si. Преимущество данной схемы обусловлено возможностью получения борсодержащего сплава попутно при выплавке ферросилиция. Экспериментально показано, что комплексный ферросиликобор имеет более высокие служебные характеристики, чем ферробор как с позиции его производства, так и  применения для обработки стали. Результаты промышленных испытаний технологии микролегирования бором трубных марок стали с использованием нового комплексного ферросплава подтвердили высокую степень усвоения бора ‒ до 96  %. Возможность широкого применения бора для микролегирования стали обусловлена его дешевизной, доступностью и экологичностью. Согласно проведенным расчетам, бор из комплексного ферросиликобора является наиболее дешевым микроэлементом, используемым для повышения прочностных характеристик стали. Добавки В2 О3 могут успешно использоваться для формирования высокомагнезиальных жидкоподвижных сталеплавильных шлаков. Показано, что 0,37  ‒  0,55  %  В2О3 эффективно стабилизирует высокоосновные шлаки сталеплавильного и ферросплавного производств, позволяя устойчиво получать товарный кусковый материал. Приведенный обзор, результаты лабораторных и  промышленных исследований показали возможность за счет широкого применения бора на разных стадиях металлургического производства повышать технико-экономические показатели производства и качество стали и ферросплавов, эффективно утилизировать отвальные шлаки. Выдвинутые и проверенные на металлургических предприятиях технические решения не требуют капитальных затрат и реализуются присадкой микродоз бора и его соединений в объекты металлургического производства.</p></abstract><trans-abstract xml:lang="en"><p>The second part of the article presents perspective directions of using boron and its compounds in the preparation processes, metallurgical processing of ore materials and steel smelting in order to improve the quality of the final product. An efficient technology of silicothermal production of ferrosilicoboron containing 0.6  –  2.0  %  B and 60  –  80  %  Si has been developed. The advantage of this scheme is the possibility of obtaining a  boron-containing alloy during ferrosilicon smelting. It has been experimentally shown that ferrosilicoboron has higher performance characteristics than ferroboron both in production and when used for steel processing. The results of industrial tests of the technology for microalloying pipe grades of steel with a new ferroalloy with boron confirmed a high degree of boron assimilation – up to 96  %. The possibility of widespread use of boron for steel microalloying is due to its cheapness, availability and environmental friendliness. According to the calculations, boron from complex ferrosilicoboron is the cheapest trace element used to increase the strength characteristics of steel. Additives of B2O3 can be successfully used to form high-magnesium liquid steel-making slags. It is shown that 0.37  –  0.55  %  В2О3 effectively stabilizes the highly basic slags of the steel and ferroalloy industries. This operation allows obtaining a marketable lump material. The above review, results of the laboratory and industrial studies have shown the effectiveness of boron usage at different stages of metallurgical production. An increase in technical and economic indicators of production and quality of steel and ferroalloys, and effective disposal of waste slags is shown. The technical solutions advanced and tested at metallurgical enterprises do not require capital expenditures. They are implemented by adding microdosing of boron and its compounds to metallurgical production facilities. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>металлургия</kwd><kwd>бор</kwd><kwd>ферросплав</kwd><kwd>сталь</kwd><kwd>шлак</kwd><kwd>физико-химические характеристики</kwd><kwd>микролегирование</kwd><kwd>стабилизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metallurgy</kwd><kwd>boron</kwd><kwd>ferroalloy</kwd><kwd>steel</kwd><kwd>slag</kwd><kwd>physical and chemical characteristics</kwd><kwd>microalloying</kwd><kwd>stabilization</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">Жучков В.И., Акбердин А.А., Ватолин Н.А. и др.
