Эксперименты по межфазному распределению бора между шлаком системы СаО – SiО2 – MgO – Al2O3 – B2O3 и металлом проводили в высокотемпературной печи электросопротивления Таммана. Использовали низкоуглеродистую сталь с различным содержанием кремния. Результаты термодинамического моделирования и экспериментальные данные показали принципиальную возможность осуществления прямого микролегирования стали бором за счет его восстановления кремнием, присутствующим в металле. Теоретически обоснован и экспериментально изучен процесс восстановления бора кремнием из шлака. Полученные при термодинамическом моделировании результаты свидетельствуют о термодинамической возможности восстановления бора из оксидной системы СаО – SiО2 – MgO – Al2O3 – B2O3 кремнием несмотря на его низкую (0,1 – 0,8 %) концентрацию в металле. При этом увеличение исходного содержания кремния в стали приводит к повышению концентрации восстановленного бора в металле. Приведены результаты, характеризующие влияние содержания кремния и температуры металла на содержание бора в стали. Показано, что выдержка металла под шлаком, содержащим 4,3 % B2O3 , сопровождается восстановлением бора. Основным восстановителем бора является кремний, содержание которого в металле после опыта снижается на 15 – 22 %. При этом в образце стали с повышенной концентрацией кремния содержится большее количество бора. Коэффициент усвоения бора составил от 5,8 до 6,9 %, что принципиально коррелирует с результатами термодинамического моделирования. Концентрацию бора в металле можно регулировать изменением температуры процесса и изменением содержания в стали кремния. Результаты исследований могут быть использованы при разработке технологии процесса прямого микролегирования стали бором.</p></abstract><trans-abstract xml:lang="en"><p>The thermodynamic calculations have been performed to study the influence of silicon (0.1 – 0.8 %), aluminum (0.005 %) and carbon (0.1 %) contained in the metal on recovery process of boron from slag with the basicity equal to 5, at temperatures of 1400 – 1700 °C with the help of software package HSC 6.1 Chemistry (Outokumpu). The experiments of interfacial distribution of boron between slag system of СаО – SiО2 – MgO – Al2O3 – B2O3 and metal have been carried out in a high temperature electrical resis­tance furnace of Tamman. The low-carbon steels with different con­tents of silicon were the base metal. The results of thermodynamic modeling and experimental data have shown that direct microalloy­ing of steel with boron are crucially possible due to boron reduce with the help of silicon in metal. The reduction of boron with slag is possible with the help of silicon in metal and the process was theo­retically based and experimentally studied. The results of thermody­namic modeling indicate the possibility of thermodynamic recovery of boron from the system of СаО – SiО2 – MgO – Al2O3 – B2O3 with the help of silicon, despite its low (0.1 – 0.8 %) concentration in the metal. The increase of the initial silicon content in the steel increases the concentration of boron in the reduced metal. The results have shown the effect of silicon content and temperature of metal on the content of boron in steel. It has been shown that an extract of the metal by slag, containing 4.3 % B2O3 , is accompanied by boron reduction. The primary reductant of boron is silicon, whose content in the metal after the experiment is reduced by 15 – 22 %. Thus, the steel sample with high concentration of silicon contains greater amount of boron. Recovery rate of boron ranges from 5.8 to 6.9 %, it is essentially correlated with the results of thermodynamic mod­eling. The concentration of boron in the metal can be controlled by changing temperature of process and content of silicon in the steel. The research results can be used in the development of the process technology of direct steel microalloying with boron.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталь</kwd><kwd>шлак</kwd><kwd>бор</kwd><kwd>термодинамическое моделирование</kwd><kwd>экспериментальные исследования</kwd><kwd>межфазное распределение бора</kwd><kwd>прямое легирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel</kwd><kwd>slag</kwd><kwd>boron</kwd><kwd>thermodynamic modeling</kwd><kwd>experimental study</kwd><kwd>interfacial distribution of boron</kwd><kwd>direct alloying</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский научный фонд (проект № 16-19-10435)</funding-statement><funding-statement xml:lang="en">Russian Science Foundation (Project no. 16-19-10435)</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">Лякишев Н.П., Плинер Ю.Л., Лаппо С.И.
