Для интенсификации процесса упрочнения окатышей на стадии жидкофазного спекания и улучшения металлургических свойств достаточно наличия в них 0,20 ‒ 0,35 % оксида бора. По данным лабораторных исследований, наличие в окатышах оксида бора повышает их прочность на сжатие в 1,5 ‒ 1,7 раза, горячую прочность ‒ в 3 ‒ 4 раза. При изучении механизма и кинетики удаления серы показано, что присутствие борного ангидрида значительно ускоряет процессы десульфурации окатышей и смещает их интенсивное протекание в область более низких температур (1050 ‒ 1100 °С). Для повышения прочностных характеристик агломерата возможна добавка в шихту В2О3 . Исследования показали, что ввод 0,44 % В2О3 приводит к снижению содержания мелочи (0 ‒ 5 мм) в 1,5 раза по сравнению с базовым образцом и не влияет на истираемость агломерата. Использование борсодержащих окатышей в доменной плавке позволило без технологических осложнений увеличить основность конечного шлака с 1,10 до 1,16, в связи с чем коэффициент распределения серы возрос с 48 до 74. Благодаря этому произошло снижение содержания серы в чугуне на 0,005 %. На основании приведенных теоретических, лабораторно-экспериментальных и промышленных данных показана возможность за счет использования бора и его соединений в процессах подготовки и металлургической переработки рудных материалов повысить технико-экономические показатели производства и качество окатышей, агломератов и чугуна.</p></abstract><trans-abstract xml:lang="en"><p>On the basis of literature and our own data, the effect of boron on characteristics of all stages of metallurgical processes (from sintering, smelting of cast iron and ferroalloys, to steel production) and on the properties of the resulting slag and metal was studied. To intensify the pellets hardening at the stage of liquid-phase sintering and to improve their metallurgical properties, it is sufficient to have 0.20 – 0.35 % of boron oxide in them. According to the laboratory studies, the presence of boron oxide in pellets increases their compressive strength by 1.5 – 1.7 times and hot strength by 3 – 4 times. While studying the mechanism and kinetics of sulfur removal, it was shown that the presence of boric anhydride significantly intensifies processes of pellets desulfurization. Their intensive progress goes to the zones of lower temperatures of 1050 – 1100 °С. To increase the sinter strength characteristics, it is possible to add B2O3 to the charge. The introduction of 0.44 % of B2O3 does not affect the sinter abrasion. The content of fines (0 – 5 mm) in comparison with the base sample is reduced by 1.5 times. The use of boron pellets in blast-furnace smelting makes it possible to increase the basicity of the final slag from 1.10 to 1.16. In this regard, the sulfur distribution coefficient increases from 48 to 74. The sulfur content in cast iron decreases by 0.005 %. The possibility of using boron and its compounds to improve the technical and economic indicators of production and the quality of pellets, sinter and cast iron is shown on the base of the presented theoretical, laboratory-experimental and industrial data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металлургия</kwd><kwd>боратовая руда</kwd><kwd>борный ангидрид</kwd><kwd>бор</kwd><kwd>низкотемпературная эвтектика</kwd><kwd>десульфурация</kwd><kwd>физико-химические свойства</kwd><kwd>механические  характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metallurgy</kwd><kwd>borate ore</kwd><kwd>boric anhydride</kwd><kwd>boron</kwd><kwd>low-temperature eutectic</kwd><kwd>desulfurization</kwd><kwd>physicochemical properties</kwd><kwd>mechanical characteristics</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed in accordance with the State Order of the IMET UB RAS within the framework of the Program of Fundamental Research of State Academies.</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">Еремин Н.И.
