Description
Предметом изобретени вл етс тигельна электрическа печь сопротивлени с включением тигел во вторичную цепь трансформатора.The subject of the invention is a crucible electric resistance furnace with the inclusion of a crucible in the secondary circuit of a transformer.
Отличительна особенность предлагаемой печи состоит в применении трехфазного тока дл нагрева тигел по методу сопротивлени , дл чего одновитковые обмотки трехфазного трансформатора замыкаютс на тигель.A distinctive feature of the proposed furnace is the use of three-phase current for heating the crucible according to the resistance method, for which the single-turn windings of the three-phase transformer are closed on the crucible.
На фиг. 1 и 2 изображены две проекции печи в разрезе.FIG. 1 and 2 shows two projections of the furnace in section.
Железный сварной тигель 1, окруженный огнеупорной кладкой 2 и набивкой , расположен внутри кожуха 4, закрываемого крышкой 5.Iron welded crucible 1, surrounded by refractory masonry 2 and gasket, is located inside the casing 4, closed by a cover 5.
В пространстве, охватываемом кожухом 4, установлены три однофазных трансформатора 6, имеющиеIn the space covered by the casing 4, three single-phase transformers 6 are installed, having
многовитковые первичные обмотки 7 и одновитковые вторичные обмотки 8 и образующие трехфазную трансформаторную группу.multi-turn primary windings 7 and single-turn secondary windings 8 and forming a three-phase transformer group.
Вторичные обмотки 8 трехфазного трансформатора замкнуты на корпус тигел 1, чем обеспечивают нагрев его и шихты по методу сопротивлени .The secondary windings 8 of a three-phase transformer are closed on the body of the crucible 1, which ensures its heating and charge by the resistance method.
