В работе освещены этапы разработки резонансно-пульсирующего рафинирования для повышения качества изделий, представлены результаты физического и математического моделирования рафинирования металла азотом и аргоном. Установлено, что физическое моделирование дает хорошую качественную картину процессов продувки металла в ковше фурмами различной конструкции. Математическое моделирование позволяет количественно рассчитать оптимальные параметры продувки аргоном и азотом в ковшах различной емкости в зависимости от их размеров, диаметра фурмы и пульсатора. Проведена оценка влияния данного типа продувки металла на газосодержание, микроструктуру чугуна, его механические свойства, а также эксплуатационные свойства полученных изделий. Установлено, что прочностные свойства чугуна возросли с 91 - 105 до 130 - 170 МПа, твердость увеличилась с 137 - 150 до 163 - 182 НВ, плотность - с 6890 - 6900 до 7000 - 7200 Кг/м3. Кроме того, необходимо отметить, что применение представленной в работе технологии позволяет значительно снизить вредное влияние фосфора. Эксплуатационная стойкость изделий из доменного чугуна достигла лучших отечественных и зарубежных показателей. Данная технология эффективно показала себя и при непрерывной разливке стали на сортовой МНЛЗ. Разработанные технологии позволили при внедрении достичь наилучших показателей в отрасли с минимальными затратами. Необходимо отметить простоту внедрения данной технологии на существующих агрегатах внепечной обработки стали и на машинах непрерывной разливки стали. Разработанные технологии можно широко использовать в литейных, электросталеплавильных и кислородно-конвертерных цехах.</p></abstract><trans-abstract xml:lang="en"><p>Currently, the technology of resonant-pulsating metal refining (RPR) becomes more widely used for refining cast iron and steel. The paper highlights the stages of development of resonant-pulsating refining to improve the quality of products and presents the results of physical and mathematical modeling of metal refining with nitrogen and argon. It is established that physical modeling gives a good qualitative picture of the processes of metal blowing in the ladle by tuyeres of various designs. Mathematical modeling allows us to quantify the optimal parameters of blowing with argon and nitrogen in ladles of different capacities, depending on the ladle size and on diameters of tuyere and pulsator. The influence of this type of metal blowing on gas content, microstructure of cast iron, its mechanical and performance properties of products made of it was evaluated. It was found that the strength properties of cast iron increased from 91 - 105 to 130 - 170 MPa, the hardness increased from 137 - 150 to 163 - 182 HB, and the density also increased from 6890 - 6900 to 7000 - 7200 Kg/m3. In addition, it should be noted that the use of the presented technology can significantly reduce the harmful effects of phosphorus. The operational stability of products made of blast-furnace cast iron has reached the best domestic and foreign indicators. This technology has also proved to be effective in continuous casting of steel on high-grade casters. It made it possible to achieve the best performance in the industry with minimal costs during implementation. The developed technology is easy to implement on existing steel non-furnace processing units and on continuous steel casting machines. It can be widely used in foundries, electric steelmaking and oxygen-converter shops.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>резонансно-пульсирующее рафинирование</kwd><kwd>фурма для продувки</kwd><kwd>примесь</kwd><kwd>расплав</kwd><kwd>температура</kwd><kwd>давление</kwd><kwd>теплота</kwd><kwd>энтальпия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>resonant-pulsating refining</kwd><kwd>lance blowing</kwd><kwd>impurity</kwd><kwd>melt</kwd><kwd>temperature</kwd><kwd>pressure</kwd><kwd>heat</kwd><kwd>enthalpy</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">Лубяной Д.А., Переходов В.Г., Фойгт Д.Б., Буймов Д.В.
