Освещены результаты разработки и совершенствования установок и методик высокотемпературного моделирования гидрогазодинамических и тепломассообменных закономерностей верхней и комбинированной продувки конвертерной ванны. Показана роль кафедры металлургии черных металлов ФГБОУ ВПО «Сибирский государственный индустриальный университет» в развитии теоретических аспектов продувки металлического расплава в конвертере газовыми струями. Благодаря использованию конвертеров со смотровыми окнами, применению специальных приемов визуализации реакционной зоны и фотокиносъемки удалось пронаблюдать и зафиксировать макрокартину физических явлений на поверхности продуваемой конвертерной ванны. Разработанная методика использования прозрачной стенки конвертера позволила получить достоверную информацию о состоянии и перемещении границы раздела шлак – металл при различных способах продувки и механизме образования выбросов. Разработанные и обоснованные основные положения методики высокотемпературного моделирования различных вариантов продувки конвертерной ванны с предложением чисел динамического подобия позволяют с большой достоверностью переносить полученные данные с модели на промышленный образец. Предложены практические варианты подхода к изучению гидрогазодинамических и тепломассообменных процессов, протекающих в основных реакционных зонах рабочего пространства конвертера при верхней и комбинированной продувке.

The paper presents the results of developing and improving thesystems and methods of high-temperature hydrogasdynamic and mass transfer modeling of top and combined blowing in a converter bath. The role of the Chair “Ferrous Metallurgy” of Siberian State Industrial University in the development of theoretical aspects of blowing the metal melt in converter with gas jets has been shown. Owing to the use of converters with viewing windows, the usage of special techniques of visualization of the reaction zone and a video, it has been able to observe and record the picture of physical phenomena on the surface of the blown bath converter with the video camera. The developed technique of a converter transparent wall has allowed obtaining reliable information on the condition and movement of slag-metal interface at various ways of blowing and formation mechanism of emissions. The developed and proved main propositions of the methodology of high-temperature simulation of different options of converter bath blowing with a proposal of the dynamic similarity criteria allow with high confidence to transferthe data obtained from the model for the industrial design. Practical options of the approach have been proposed to study hydrogasdynamic and heat-and-mass transfer processes occurring in the main reaction zones of a converter workspace at the top and combined blowing.
