Description

(54) INDUCTION DUCT FURNACE

one

The invention relates to electrical engineering, in particular to induction furnaces.

Single-channel inductive channel circuits are known, in which the OKE movement is achieved due to the pressure differential at the mouth of a channel with different price lines | AND tl.

However, the development of this movement in the direction of creating intensive cKBOSiHoro metal movement through the channel allows reducing the heating of the metal in the metal to a minimum / minimum and thereby ensuring the long service life of the induction units while increasing their power.

Also known (induction-ion channel and furnace, containing a bath, two parallel channels located below it, an inductive one, made in the form of a paused magnetic conductor with an alternating current winding placed on it, and an electro-magnetic stator Ii2.

The limestone kiln underpasses are the design complexity and the increased dimensions of the kiln due to the use of two stators with a structurally complex core winding.

The aim of the invention is to simplify the design of the furnace.

The goal is achieved by the fact that an electromagnetic stator is installed between the channels and is made with a drum winding.

FIG. 1 and 2 depict an induction channel furnace; “And FIG. 3 and 4 are diagrams for connecting the electro-pnit stator.

The furnace contains a bath / connected to one single unit 2, consisting of a core 3, made of electrical steel with a coil 4 alternating current wound on it, having two parallel channels -5. Electromagnetic stator 6 is installed between the channels.

15 winding drum type, creating in the gaps 7 and S running electromagnetic field.

The stator is connected to the polyphase network one at a time (FROM known circuits, which allow to obtain a running field.

For e: that stator coil 9-12 is connected to the 1K network. The stator is made, for example, of a two-phase version, its core 13 is made of electrical steel.

25 When the contactor 14 is turned on in gaps 7 and 8 |, a running magnetic field is created in the channel between the working part of the stator and the metal. As a result of this, you have a metal in the channel with the current induced by it in the metal in the channel. is given, in movement in the direction of the peremesh.e and the magnetic field.

Thanks for picking up 1 the stator between the channels and the use of a drum winding having IB in this case two working parts (parts, facing: to the channels), 0Д1И1н the stator set in motion the metal simultaneously in two parallel channels, as a result of which it is eliminated unwanted overheating of the metal in the channels.
