Description
II
Изобретение относитс к закрытой электрической печи дл производства железных сплавов, например таких как ферросилиций с содержанием кремни свыше 70%. Герметизаци печи затруднена ввиду того, что имеют место большие колебани давлени в печи, а температура в ней стремитс повыситьс настолько.что это приводит к повреждению сборок, примыкающих к электродам.The invention relates to a closed electric furnace for the production of iron alloys, such as, for example, ferrosilicon with a silicon content of over 70%. The sealing of the furnace is difficult due to the fact that there are large pressure fluctuations in the furnace, and the temperature in it tends to increase so much that this leads to damage to the assemblies adjacent to the electrodes.
В закрытой электрической печи ровна иIn a closed electric oven, it is smooth and
непрерывна работа затруднена в том случае, если трубки дл загрузки исходной шихты не установлены в пределах зоны, в которую должна попадать загружаема шихта, причем это особенно относитс к трубкам дл загрузки исходной шихты, которые одновременно служат в качестве трубок, всасываюших газы. Если нижн часть трубок забита исходной шихтой или пылью работа их становитс невозможной. При вдувании указанных веществ в печь или же при загруэ ке исходной щихты в печь имеют место ненормальиые колебани давлени и в то же врем в некоторой части печи будет иметь место тепловое излучение вследствие ненормально высокойContinuous operation is difficult if the tubes for loading the initial charge are not installed within the zone into which the charge to be charged must fall, and this is especially true for the tubes for loading the initial charge, which also serve as suction tubes. If the lower part of the tubes is clogged with the initial charge or dust, their operation becomes impossible. When these substances are blown into the furnace, or when the initial mixture is loaded into the furnace, abnormal pressure fluctuations take place and at the same time, thermal radiation will occur in some part of the furnace due to abnormally high
температуры, в результате чего возможно повреждение кожуха печи и различных устройств, св занных с злектродом. Следовательно, печь работает в неблагопри тных услови х.temperature, resulting in damage to the furnace shell and various devices associated with the electrode. Consequently, the furnace operates in adverse conditions.
Чтобы устранить,отмеченные недостатки, желательно располржит ь Трубки дл загрузки шихты настолько близко к электродам, насколько это возможно, и сделать пространство между загруженной шихтой и кожухом печи достаточно большим.In order to eliminate marked deficiencies, it is advisable to expand the tubes for loading the charge as close to the electrodes as possible, and to make the space between the loaded charge and the furnace shell large enough.
Известна электрическа печь закрытого типа , котора содержит ванну, свод, электроды, наружные поверхности которых охватывает защитный охлаждаемый элемент, устройство дл загрузки шихты 1.The known electric furnace of the closed type, which contains a bath, a vault, electrodes, the outer surfaces of which are covered by a protective cooled element, a device for loading charge 1.
