Установлена принципиальная возможность использования полукокса в составе углеродной части шихты в качестве базового восстановителя для производства ферросиликомарганца. Отмечено, что новый восстановитель в чистом виде работает хуже, чем в смеси с углем. Показано, что наибольший синергетический эффект при производстве ферросиликомарганца достигнут при работе полукокса вместе с углем, при этом достигнуты максимальная производительность печи 43 т/сутки, максимальный коэффициент извлечения 87,9 %, минимальное удельное образование пыли 49 кг/т сплава. Выявлено, что при производстве ферросилиция использование нового восстановителя не дало существенного положительного эффекта, в том числе из-за его низкой структурной прочности. Отмечено, что на производительность печи влияют структура и вид восстановителя: при использовании в шихте восстановителя с более высокой реакционной способностью возможно получение более высоких производственных показателей печи. При производстве ферросилиция изменение удельного пылеобразования тесно связано с уровнем суточного производства и удельным расходом электроэнергии и может служить индикатором работы печи. Производительность печи при прочих равных условиях определяется величиной вводимой полезной мощности. При избытке углерода в шихте увеличение полезной мощности приводит к незначительному увеличению производительности печи, но при этом существенно увеличивается расход электроэнергии и удельное пылеобразование. Влияние технологических факторов на технико-экономические показатели плавки определяется степенью посадки электродов в печи.</p></abstract><trans-abstract xml:lang="en"><p>The article presents results of testing semi-coke as a carbon reducing agent in the production of manganese and silicon alloys. The fundamental possibility of using semi-coke in carbon part of the charge as a basic reducing agent for the production of ferrosilicon manganese is established. It is noted that the new reducing agent in its pure form works worse than in the mixture with coal. The greatest synergistic effect in the production of ferrosilicon manganese was achieved during the interaction of semi-coke with coal, while the following indicators were obtained: maximum furnace productivity of 43 t/day, maximum extraction coefficient of 87.9 %, and minimum specific dust formation of 49 kg/t of alloy. In the production of ferrosilicon the use of a new reducing agent did not give a significant positive effect, due to its low structural strength. It was revealed that the structure and type of the reducing agent affect the furnace performance: when using a reducing agent with a higher reactivity in the charge, it is possible to obtain higher furnace performance. In the production of ferrosilicon, a change in the specific dust generation is closely related to the level of daily production and specific energy consumption and can serve as an indicator of the furnace operation. The furnace performance, ceteris paribus, is determined by the amount of useful power input. With an excess of carbon in the charge an increase in useful power leads to a slight increase in the furnace performance, but at the same time, the energy consumption and specific dust formation significantly increase. It is shown, that the influence of technological factors on the technical and economic indicators of melting is determined by the degree of electrode seating in the furnace.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полукокс</kwd><kwd>твердый углеродистый восстановитель</kwd><kwd>ферросилиций</kwd><kwd>ферросиликомарганец</kwd><kwd>ферросплавное производство</kwd><kwd>технологические свойства</kwd><kwd>реакционная способность</kwd><kwd>применение в металлургии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>semi-coke</kwd><kwd>solid carbonaceous reducing agent</kwd><kwd>ferrosilicon</kwd><kwd>ferrosilicon manganese</kwd><kwd>ferroalloy production</kwd><kwd>technological properties</kwd><kwd>reactivity</kwd><kwd>application in metallurgy</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">Галевский Г.В., Аникин А.Е., Руднева В.В., Галевский С.Г.
