Description

Предлагаетс  трехфазна  индукцлопио-дугова  электроплавильна  Jie4b с пезамкмутим сердечником и с системой обмоток, создающих в тигле вран1агои|еес  магнитное поле.A three-phase induction-arc electric Jie4b electrofusion mill with a pezamkmutim core and a system of windings creating a magnetic field in the crucible is proposed.

Основным недостатком известных иечей подобного рода  вл етсм /о, что онп не обеснечнг ают возможности регулировани  частот)) тока в тигле.The main disadvantage of such well-known Yechs is that it does not provide for the possibility of controlling the frequency of the current in the crucible.

В иредла аемой иечи указанный недостаток устрапен. б.тагодар  вьпюлпегипо тш.л  вращаюгцихс  под действием магпитпо1о нол , созлаваемого сердечпнком, подобно ротору индукционного двигател .In iredla aema yechi, this deficiency has been settled. B. Tgodar vypylpegipo tshl. rotate under the influence of magpitopo1ol, called by the heart, like a rotor of an induction motor.

Вместе с тем нредлагаема  печь обесиечнвает равномерную нагрузку всех фаз сети и увеличивает гибкость управлени  пропессом Но1авле1П1  1зследствне примененн  комбнпированного нагре1 а, регулируемого путем изменени  частоты тока is тигле.At the same time, the proposed furnace provides a uniform load for all phases of the network and increases the flexibility of controlling the process by using the combined heating, which is controlled by changing the current frequency of the crucible.

Ila фиг. i и 2 нргизедены два варианта вынолиенп  предлагаемой иечи, обипп ; , на фпг. 3 н 4-их электрические схемьгIla FIG. i and 2 ргrgizedeny two options for the proposed Yiechi, obipp; on fpg. 3 n 4th electric circuit

При первом вариаите (фиг. 1 и 3) вокруг тигл  / на его футеровке расио;гожена короткозамкнута  обмотка 6, вынолнерп1а  нз медных HJHH в внде беличьего колеса и обеснеч1 ваю)па  создание вращающего момента требуемой велнчины.At the first variation (figs. 1 and 3) around the crucible / on its lining racio; winding 6 is short-circuited, winding with copper HJHH in the inner squirrel wheel and rendering the required torque.

С наружной стороны тигл  / расноложен кольцевой магнитопровод 2, выиолпепиьи из листов электротехппческой стали. Па магнитопроводе 2 установлены симметрично но окружности трп нлп шесть сердечников 3. иа которых размещены первична  обмотка 4, питаема  трехфазным токо.м и создающа  вращаюн1еес  магнитное поле, и вторична  обмотка 5, предназиаченна  дл  1Н(тани  электродов 7 печи током пониженного нанр жени .

The magnetic core 2 is mounted symmetrically on the circumference of the trp nlp six cores 3. of which the primary winding 4 is located, powered by a three-phase current and creates a rotating magnetic field, and the secondary winding 5, designed for 1H (low-voltage current electrodes 7 of the furnace with reduced current) 7 are mounted on the ienodobile arch 8. The housing of the furnace is placed on a rotating platform. I am equipped with a braking tool W.
