Description
Изобретение относитс к области черной металлургии, в частности к ферросплавным печам.This invention relates to the field of ferrous metallurgy, in particular to ferroalloy furnaces.
Известна рудовоостановительна дугова электропечь, состо ща из ванны, стен, свода с песочным затвором , электродов и устройства дл загрузки шихты, выполненное в виде В01ЮНОК, установленных вокруг электродов ,A well-known ore-stopping arc furnace consisting of a bath, walls, a vault with a sand gate, electrodes and a device for loading the charge, made in the form of B01UNOC installed around the electrodes,
Неудовлетворительный электрический режим печи вызван тем, что контактные щеки электродераателей. приходЕСтс располагать выше верхнего среза воронок на 0,5-0,7 м,что приводит к большой длине свободного конца электрода.The unsatisfactory electric mode of the furnace is caused by the fact that the contact cheeks of the electric guns. the arrival of the ESE is 0.5-0.7 m above the upper end of the funnels, which leads to a large length of the free end of the electrode.
Цель изобретени - улучшение электрического режима печи.The purpose of the invention is to improve the electric mode of the furnace.
Это достигаетс тнм, что выход ные патрубки загрузочных воронок установлены в ноже песочного затвора равномерно по периметру печи, что позвол ет сократить длину свободаого конца электрода и в то же вревд обеспечивает образованиеIt is achieved that the outlet outlets of the hoppers are installed in the sandgate knife evenly around the perimeter of the furnace, which reduces the length of the free end of the electrode and at the same time ensures the formation of
конусов шихты вокруг каждого из электродов со всех сторон,charge cones around each of the electrodes from all sides,
На чертеже схематично показана предлагаема рудовосстановительна дугова электропечь.The drawing shows schematically the proposed ore recovery arc furnace.
Печь I содержит свод 2 с утопленными контактными щетками электродержател 3, Свод имеет водоохлаждаемый нож 4, высота которого достаточна дл размещени в ней выходных патрубков загрузочных воронок 5, обеспечиващих подачу шихты отдельными порци ми или непрерывно в секторе, составл ющем 15-25 ,The furnace I contains a roof 2 with recessed contact brushes of an electric holder 3.
При подаче шихты с помощью загрузочных воронок, вокруг электрода образуютс конусы шихты, которые поддерживаютс по мере пррплавлени шихты;When feeding the charge with the help of hoppers, charge cones are formed around the electrode, which are maintained as the charge progresses;
Предмет изобретени Subject invention
Рудовосстановительна дугова электропечь, состо ща из ванны, стен, свода с песочным затвором, имеищш нож, электродов и загрузочных воронок, отличакща с тем, что. с целью улучшени электрического режима печи, выходные патрубки за444 8ЯAn ore-healing electric arc furnace consisting of a bath, walls, a vault with a sand gate, a knife, electrodes, and charging funnels is different from that. in order to improve the electric mode of the furnace, the exhaust pipes for 444 I
грузочных врронок установлены в ноже песочного затвора равномерно по периметру печи;load drums are installed in the sandblade knife evenly around the perimeter of the furnace;
