Разработана математическая модель и выполнен расчет параметров течения сверхзвуковой нерасчетной струи с учетом присоединения в рабочем объеме конвертера емкостью 350 т не только газа, но и частиц шлака. Получены среднемассовые значения температуры и скорости по длине газовой струи. Установлено влияние присоединенной массы шлака на присоединенную массу газа, температуру газовой струи и ее скорость с учетом изменений расхода азота через сопло и относительной температуры в рабочем пространстве конвертера. Анализ результатов численных расчетов показал, что эжектирование шлака существенно изменяет картину взаимодействия трехкомпонентной сверхзвуковой нерасчетной струи с расплавом, при этом даже незначительное присоединение шлака к газовому потоку способствует заметному уменьшению скорости распространения струи</p></abstract><trans-abstract xml:lang="en"><p>This paper presents a method for calculating the basic parameters of the gas jet (average temperature and power) at a certain distance from the nozzle exit in the technology implementation of blowing molten slag on the refractory lining of the converter. The mathematical model has been worked out and the ﬂ ow parameters of the supersonic noncalculated jet, considering joining in the working volume of 350-t converter not only gas but also slag particles, have been calculated. Average weight values of temperature and velocity over the length of the gas jet have been obtained. The effect of the added slag mass on the added mass of gas, the temperature of the gas jet and its rate subject to the changes in the ﬂ ow of nitrogen through the nozzle and the relative temperature in the working space of the converter has been established. The analysis of the results of numerical calculations has showed that the slag ejection changes signiﬁ cantly the picture of the interaction of ternary supersonic noncalculated jet with the melt, at the same time even a slight attachment of slag to the gas ﬂ ow promotes noticeable decrease of the propagation velocity of the jet.</p></trans-abstract><kwd-group xml:lang="en"><kwd>supersonic jet</kwd><kwd>slag attachment</kwd><kwd>velocity</kwd><kwd>cavity of converter</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">Kim D.-S, Cho J.-W., Chung C.-Y.
