Проанализированы особенности процессов выплавки алюминиевых сплавов с использованием комплексных методов печной и внепечной обработки шихтового материала, содержащего повышенное количество мелкого возврата и стружки. Исследования по определению влияния подготовки шихты и технологии переплавки алюминия на выход годного проведены в печах САТ-0,16 и ИАТ-0,4 на сплаве АК12М2. Экспериментально установлено, что порционная загрузка в печь САТ-0,16 по 20 кг брикетированной стружки, предварительно нагретой до 300– 400 °С, с последующим добавлением флюса (состав: NaCl – 50 %, KCl – 35 %, Na3AlF6 – 15 %) в количестве 3 % от металлозавалки является наиболее эффективной технологией и позволяет добиться выхода годного порядка 94 %. Изучение влияния технологии переплава на выход годного в печи ИАТ-0,4 показало, что наибольший эффект можно получить при загрузке садки (95 кг брикетированной стружки) частями по 2 кг в жидкую ванну массой 7 кг с порционной добавкой флюса (состав: NaCl – 62 %, KCl – 13 %, NaF – 25 %) в количестве 2 % от металлозавалки. Такая технология позволяет получить до 93,5 % годного металла. Проанализированы данные 10 серий по 5–9 плавок и приведены сравнительные результаты по определению выхода годного металла в зависимости от массы загружаемой брикетированной стружки в печь. Получена гистограмма изменения пористости образцов из сплавов АК12М2 и АК9 в зависимости от содержания стружки в шихте (от 0 до 45 %) при переплаве. Установлено, что при прочих равных условиях увеличение содержания стружки в шихте приводит к росту среднего балла по пористости, что свидетельствует о необходимости дополнительного рафинирования таких расплавов.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of research determining the most effective technologies for increasing metal yield in the processing of aluminum-containing waste. In particular, peculiarities of the processes of melting aluminum alloys were analyzed using complex methods of furnace and off-furnace processing of charge material containing an increased amount of shovelling scrap and swarf. Studies on the impact of charge preparation and aluminum remelting technology were carried out in SAT-0,16 and IAT-0,4 furnaces on the АК12М2 alloy. Experiments proved that batchwise loading 20 kg of swarf briquette preheated to 300–400 °C into the SAT-0,16 furnace with the addition of flux (composition: NaCl – 50 %; KCl –35 %, Na3AlF6 – 15 %) in the amount of 3 % of total metal mass is the most efficient technology. This technology makes it possible to achieve a metal yield of about 94 %. The study of the remelting technology influence on IAT-0,4 furnace metal yield showed that the greatest effect can be obtained in case of furnace charge (95 kg swarf briquette) by batches of 2 kg into the 7 kg liquid bath with modifier flux (composition: NaCl – 62 %; KCl – 13 %, NaF – 25 %) added in the amount of 2 % from the total metal mass. This technology provides up to 93.5 % of metal yield. Data from 10 series of 5–9 melts were also analyzed with the comparison of metal yield results depending on the mass of briquetted swarf charged into the furnace. A histogram of the change in the porosity of AK12M2 and AK9 samples depending on the content of swarf in the charge (from 0 to 45 %) during remelting. It was found that an increase in the content of swarf in the charge, all other things being equal, leads to an increase in the average porosity score, which indicates the need for additional refining of such melts.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминий</kwd><kwd>расплав</kwd><kwd>подготовка отходов к переплаву</kwd><kwd>плавильная печь</kwd><kwd>гидродинамика</kwd><kwd>флюсы</kwd><kwd>неметаллические включения</kwd><kwd>легирование</kwd><kwd>модифицирование</kwd><kwd>рафинирование</kwd><kwd>качество литого металла</kwd><kwd>выход годного</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum</kwd><kwd>melt</kwd><kwd>waste preparation for remelting</kwd><kwd>melting furnace</kwd><kwd>hydrodynamics</kwd><kwd>f luxes</kwd><kwd>non-metallic inclusions</kwd><kwd>alloying</kwd><kwd>modification</kwd><kwd>refining</kwd><kwd>cast metal quality</kwd><kwd>yield</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">Потребление алюминия, основные потребители — Алюминиевая ассоциация. http://www.aluminas.ru/aluminum/in_the_world/ (дата обращения: 15.07.2020).</mixed-citation><mixed-citation xml:lang="en">Consumption of aluminum, basic consumers’ — Aluminum association. http://www.aluminas.ru/aluminum/in_the_world/ (accessed: 15.07.2020) (In Russ.).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Деев В.Б., Пономарева К.В., Куценко А.И., Приходько О.Г., Сметанюк С.В.
