В ферросплавных печах постоянного тока исключается такой параметр, как коэффициент мощности в электропечном контуре после преобразователя тока. Многие исследователи предполагали, что выплавка ферросплавов в печах, работающих на постоянном токе, позволит интенсифицировать процесс плавления шихты, улучшить извлечение ведущего элемента ферросплава и снизить удельный расход электроэнергии. Проведен краткий анализ сравнения выплавки углеродистого феррохрома в печах переменного и постоянного тока на основе комплексного параметра – энерготехнологического критерия работы ферросплавной электропечи. Показано, что при сопоставимой активной мощности в ванне энерготехнологический критерий печи переменного тока выше (0,2185 – 0,2381) по сравнению с энерготехнологическим критерием печей постоянного тока (0,1109 – 0,1320) при освоенном уровне технологии выплавки углеродистого феррохрома. Соответственно, в печах переменного тока удельный расход электроэнергии на выплавку углеродистого феррохрома на 20 – 28 % ниже, чем в печах постоянного тока.</p></abstract><trans-abstract xml:lang="en"><p>One of the interesting technical solutions is technology of ferroalloys smelting using direct current (DC). In DC ferroalloy furnaces, apparently, it is possible to eliminate such a parameter as power factor in furnace circuit after current converter. Many researchers assume that melting at direct current allows intensification of the process of charge melting, increases reduction of leading elements of ferroalloy and reduces specific consumption of electricity. In this paper, brief analysis of carbon ferrochromium smelting in alternating current (AC) and in direct current (DC) furnaces is made based on energotechnological criterion of ferroalloy electric furnace performance. It is shown that with comparable active capacity in bath, AC furnaces have higher energotechnological criteria (0.2185 – 0.2381), compared to DC furnaces (0.1109 – 0.1320), at current level of technology used for carbonaceous ferrochrome smelting. Thus, in AC furnaces, specific electric power consumption in ferrochrome smelting is lower than in DC furnaces by 20 – 28 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ферросплавы</kwd><kwd>электропечь</kwd><kwd>постоянный ток</kwd><kwd>переменный ток</kwd><kwd>извлечение хрома</kwd><kwd>удельный расход электроэнергии</kwd><kwd>феррохром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ferroalloys</kwd><kwd>electric furnace</kwd><kwd>direct current</kwd><kwd>alternating current</kwd><kwd>extraction of chromium</kwd><kwd>specific electricity consumption</kwd><kwd>ferrochrome</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">Gelgenhuys I.J.
