Arc furnace

Изобретение относится к области металлургии и касается дуговой печи, имеющей металлоприемник печи для плавления стали, свод для закрытия металлоприемника печи и устройство поворота, выполненное с возможностью отведения свода от металлоприемника печи, который установлен подвижно с возможностью движения в вертикальном направлении относительно устройства поворота, которое имеет замок, выполненный с возможностью разъемной фиксации свода. При этом свод выполнен с возможностью фиксации в вертикальном направлении замком устройства поворота и отделения от металлоприемника печи при движении в вертикальном направлении. Изобретение позволяет обойтись без шарнирного цилиндра благодаря подвижной в вертикальном направлении установке металлоприемника печи вместе со сводом, что дает экономию необходимых конструктивных элементов и трудоемкой механической обработки механизма подъема свода. Кроме того, свод и устройство поворота не опрокидываются вместе с металлоприемником печи, так что возможен выпуск при одновременной подаче энергии к печи или электродам, что позволяет увеличить производительность печи. 7 з.п. ф-лы, 3 ил.
