К таким областям применения относятся кухонная утварь, мебель, медицинское оборудование, ядерные реакторы, косми­чес­кие аппараты и т. д. Кислород в стали, особенно в коррозионностойкой, является одним из самых вредных элементов. Оксидные включения нарушают гомогенность металла, отрицательно влияют на пластичность, вязкость разрушения, усталостную прочность и коррозионную стойкость стали. В коррозионностойких сталях неметаллические включения (НВ) приводят к образованию дефектов в холоднокатаном листе. Включения алюминатов также приводят к засорению сталеразливочного оборудования. В работе выполнен анализ технологии производства коррозионностойкой стали 08Х8Н10Т с целью определения причин образования НВ, влияющих на разливаемость стали и ее качество. В ходе исследований определено содержание общего кислорода и азота, а также кислорода, связанного в различные НВ на стадиях ковшевой обработки и непрерывной разливки стали. После введения в расплав титановой проволоки общее содержание азота снижается за счет образования и последующего удаления нитридов титана. При этом увеличивается содержание оксидов титана в расплаве. Показано, что причинами засорения сталеразливочных стаканов при непрерывной разливке являются комплексные НВ на основе оксидов титана, которые осаждались на внутренней поверхности разливочного стакана-дозатора. В работе даны рекомендации по корректировке технологии выплавки стали в ДСП и ковшевой обработки. По результатам электронно-микроскопического анализа установлено, что перемешивание рафинирующего жидкоподвижного шлака в агрегатах ковшевой обработки стали способствовало ассимиляции НВ шлаком и уменьшению их размеров в металле. После внедрения корректирующих рекомендаций засорения сталеразливочных стаканов при непрерывной разливке не наблюдалось.</p></abstract><trans-abstract xml:lang="en"><p>Corrosion-resistant steels are in demand in the modern world due to their high performance properties and a wide range of applications. Such areas of application include kitchenware, furniture, medical equipment, nuclear reactors, spacecraft, etc. Oxygen in steel, especially in corrosion-resistant steel, is one of the most harmful elements. Oxide inclusions disrupt the homogeneity of the metal, negatively affect the ductility, fracture toughness, fatigue strength and corrosion resistance of steel. In corrosion-resistant steels, non-metallic inclusions (NI) lead to the formation of defects in cold-rolled sheets. Aluminate inclusions also lead to clogging of steel-casting equipment. An analysis of the production technology of corrosion-resistant steel 08Kh8N10T was carried out in order to determine the causes of NI formation that affect the pourability of steel and its quality. The studies determined the content of total oxygen and nitrogen, as well as oxygen bound in various non-metallic inclusions at the stages of ladle processing and continuous steel casting. It was shown that after the introduction of titanium wire into the melt, the total nitrogen content decreases due to the formation and subsequent removal of titanium nitrides. At the same time, the content of titanium oxides in the melt increases. It was shown that the causes of clogging of steel-pouring nozzles during continuous casting are complex non-metallic inclusions based on titanium oxides, which were deposited on the inner surface of the pouring nozzle-doser. Recommendations were made to adjust the technology of steel melting in EAF and ladle processing. Based on the results of electron microscopic analysis, it was established that mixing of refining liquid-mobile slag in ladle steel processing units contributed to the assimilation of non-metallic inclusions by slag and a decrease in their sizes in the metal. After the implementation of the corrective recommendations, clogging of steel-pouring nozzles during continuous casting was not observed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коррозионностойкая сталь</kwd><kwd>фракционный газовый анализ</kwd><kwd>оксидные неметаллические включения</kwd><kwd>качество стали</kwd></kwd-group><kwd-group xml:lang="en"><kwd>corrosion-resistant steel</kwd><kwd>fractional gas analysis</kwd><kwd>non-metallic oxide inclusions</kwd><kwd>steel quality</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">Beddoes J., Parr J.G.
