Description

В основном патенте № 2129 описана электрическа  дугова  печь с одной или несколькими электрическими дугами, вращающимис  под вли нием магнитного пол  вокруг подвижных угольных электррдов. В случае применени  трехфазного тока каждый из трех подвижных электродов печи окружен катушкой, включенной через трансформатор тока в ту фазу, к которой присоединен данный электрод. Согласно предлагаемому изобретению в упом нутой печи применена только одна катушка, окружающа  плавильное пространство.The main patent no. 2129 describes an electric arc furnace with one or several electric arcs rotating under the influence of a magnetic field around movable carbon electrodes. In the case of a three-phase current, each of the three moving electrodes of the furnace is surrounded by a coil connected through a current transformer to the phase to which this electrode is connected. According to the invention, only one coil is used in the above-mentioned furnace, surrounding the melting space.

На чертеже схематически изображена трехфазна  дугова  печь.The drawing shows schematically a three-phase arc furnace.

Катушка возбуждени  4, включенна  в одну из фаз цепи либо последовательно (непосредственно), либо через трансформатор тока, расположена в верхней части печи и выполнена в виде полой бедной трубки, охлаждаемой непрерывно циркулирующей по ней водой. Таким включением и расположением катушки 4 имеетс  в виду осуществить вращение только одной дуги и именно той, в фазу которой включена катушка 4. Остальные две дуги под вли нием магнитного пол  этой катушки привод тс  в колебани  с частотой , равной частоте трехфазного тока.The excitation coil 4, included in one of the phases of the circuit, either sequentially (directly) or through a current transformer, is located in the upper part of the furnace and is made in the form of a hollow, poor tube cooled by water that is continuously circulating through it. This inclusion and arrangement of coil 4 is meant to rotate only one arc and that one in the phase of which coil 4 is turned on. The other two arcs under the influence of the magnetic field of this coil are oscillating at a frequency equal to the frequency of the three-phase current.

Предлагаема  печь, в отличие от печей с неподвижной дугой, так же как и печь, описанна  в основном патенте, может работать при более высоком напр жении, дает более равномерный нагрев ванны, вследствие большого объема дуги, и имеет большую устойчивость, что и позвол ет работать без автоматических регулирующих устройств. Кроме того в отличие от печей с одним электродом описанна  печь примен етс  только в случае необходимости непосредственного действи  дуги на металл, например, дп  переплавки, рафинировани  и получени  металлов.The proposed furnace, unlike the fixed-arc furnaces, as well as the furnace described in the main patent, can operate at a higher voltage, provides a more uniform heating of the bath, due to the large volume of the arc, and has greater stability, which allows work without automatic control devices. In addition, in contrast to single-electrode furnaces, the described furnace is used only when it is necessary to directly act on the metal, for example, dp remelting, refining and producing metals.

Предмет изобретени .The subject matter of the invention.

Видоизменение электрической дуговой печи, охарактеризованной в патенте № 2129, отличающеес  тем, что, с целью вращени  лишь одной из дуг трехфазной печи и приведени  в колебание двух других дуг. применена только одна окружающа  плавильное пространство печи катушка возбуждени  4, включенна  последовательно непосредственно или через трансформатор тока в одну из фаз печи. iK авторскому свидетельству Г.
