Abstract

Описаны способ и устройство для предварительного нагрева и плавки агломерата марганцевой руды. Способ включает подачу исходной смеси (1), содержащей агломерат (2) марганцевой руды, восстанавливающий агент (3) и флюсующую добавку (4), в дуговую электропечь (5) с закрытой дугой; плавление исходной смеси (1) с образованием слоя, содержащего жидкий сплав марганца, и слоя, содержащего шлак; отбор жидкого марганца и при выпуске содержащего моноксид углерода углеродсодержащего газа (6) сжигание содержащего моноксид углерода углеродсодержащего газа (6) в присутствии кислорода, например воздуха, в горелке (7), с образованием содержащего диоксид углерода углеродсодержащего газа (9); и нагревание указанной исходной смеси (1) в бункере (8) предварительной обработки указанным содержащим диоксид углерода углеродсодержащим газом (9) перед подачей указанной исходной смеси (1) в дуговую электропечь (5) с закрытой дугой.A method and apparatus for preheating and smelting manganese ore sinter are described. The method includes supplying the initial mixture (1) containing agglomerate (2) of manganese ore, reducing agent (3) and fluxing additive (4) to the electric arc furnace (5) with a closed arc; melting the initial mixture (1) to form a layer containing a liquid manganese alloy and a layer containing slag; selection of liquid manganese and with the release of carbon-containing gas containing carbon monoxide (6) burning carbon-containing carbon-containing gas (6) in the presence of oxygen, such as air, in the burner (7), to form carbon-containing carbon dioxide (9); and heating the specified initial mixture (1) in the pre-treatment bin (8) with the specified carbon dioxide-containing carbon dioxide (9) before supplying the specified initial mixture (1) to the electric arc furnace (5) with a closed arc.
