Определено минимальное значение в нем кислорода, при котором введение кремния приведет к раскислению не по всему объему с формированием оксидов кремния, а к поверхностному, по границе «кремний – окисленный расплав меди», с образованием жидкого Cu–Si-сплава, не смешивающегося с основным расплавом и принимающего форму «шарика» общей массой 5–10 % от всего расплава. Описан механизм появления этих «шариков». Установлено, что на скорость их образования влияет количество кислорода в медном расплаве. Полученные результаты имеют ценность с практической точки зрения и могут быть использованы в производстве медных сплавов.</p></abstract><trans-abstract xml:lang="en"><p>The paper examines the features of silicon behavior (neat – Kr0 grade, alloy – Cu–50 % Si) when introduced into oxidized copper melt. The minimum value of oxygen content in copper was found. With this value silicon introduction leads not to deoxidation of the entire volume with silicon oxide formation, but only to surface deoxidation at the «silicon/oxidized molten copper» interface with the formation of liquid Cu–Si alloy immiscible with the main melt and shaped as a ball with a total weight of 5–10 % of the whole melt. The mechanism of such ball appearance was described. It was found that the ball formation rate is affected by the amount of oxygen in molten copper. The results obtained are valuable from a practical perspective and may be used in copper alloy production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медный расплав</kwd><kwd>кремний</kwd><kwd>раскисление</kwd><kwd>содержание кислорода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molten copper</kwd><kwd>silicon</kwd><kwd>deoxidation</kwd><kwd>oxygen content</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">Коновалов А.Н., Пикунов М.В., Герасимов С.П.
