A short-circuit ring (40) which is a non-closed metal ring is arranged above the induction coil (10) and is fixed to the upper ends of the positioning plates (20), a water outlet (501) and a water inlet (502) are arranged on the short-circuit ring (40), the width of an opening (401) of the short-circuit ring is larger than or equal to three centimeters, and a sealing fin (402) is arranged at the end of the short-circuit ring (40). Compared with the prior art, the medium-frequency furnace induction coil structure has the advantages that the short-circuit ring is set as the non-closed metal ring and accordingly cannot generate a magnetic field, and the magnetic isolation effect of the short-circuit ring is enhanced.
Description
Technical field
The utility model relates to a kind of structure of middle frequency furnace induction coil, especially relates to a kind of middle frequency furnace induction coil with separated magnetic effect.
Background technology
Induction coil is the most important part of middle frequency furnace, and its operating efficiency directly affects the performance of middle frequency furnace.In the prior art, the induction coil of middle frequency furnace comprises spiral induction coil and location-plate, and location-plate is through the distance between bolt location induction coil circle and the circle.In the middle frequency furnace course of work of prior art, the leakage field phenomenon can appear in the induction coil top, causes the circuit panel induction of induction coil top; Rubescent heating; Cause panel to melt when serious, influence the operate as normal of middle frequency furnace, the induction coil leakage field also can influence its service behaviour simultaneously.The general method that solves the induction coil leakage field is that a short-circuited conducting sleeve is set above induction coil; This short-circuited conducting sleeve can effectively shield the magnetic field that induction coil produces; Reduce the heating of electric furnace top device, short-circuited conducting sleeve itself also produces some magnetic fields, though compare with the magnetic field that induction coil produces; The magnetic field that short-circuited conducting sleeve produces is very little, but also can influence the shield effectiveness of short-circuited conducting sleeve.
Summary of the invention
The utility model is to the deficiency of middle frequency furnace induction coil of the prior art, and a kind of short-circuited conducting sleeve and middle frequency furnace induction coil that can effectively separated magnetic of having is provided.
For solving the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of structure of middle frequency furnace induction coil comprises induction coil and location-plate, and location-plate is connected the outside of induction coil through bolt; Said induction coil top is provided with short-circuited conducting sleeve, and said short-circuited conducting sleeve is fixed on the upper end of location-plate, and said short-circuited conducting sleeve is provided with delivery port and water inlet; It is characterized in that said short-circuited conducting sleeve is non-closed becket, its fracture width is more than or equal to 3 centimetres; Said short-circuited conducting sleeve end is provided with diaphragm seal; Short-circuited conducting sleeve is arranged to non-closed round ring, makes short-circuited conducting sleeve self not generate an electromagnetic field, improve the separated magnetic effect of short-circuited conducting sleeve.
In the technique scheme, said short-circuited conducting sleeve is the non-closed copper ring that copper pipe surrounds.The thermal conduction effect of copper pipe is good, and cost is relatively low.
In the technique scheme, said diaphragm seal is welded on the end of short-circuited conducting sleeve.Adopt the mode of welding that diaphragm seal sealing short-circuited conducting sleeve is set, reduce manufacturing cost.
In the technique scheme, two ends of said short-circuited conducting sleeve are respectively equipped with delivery port and water inlet, fully improve the circulation cooling effect.
Compared with prior art, short-circuited conducting sleeve is set to the becket of non-closure, makes short-circuited conducting sleeve itself can not produce magnetic field, has increased the separated magnetic effect of short-circuited conducting sleeve.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1; A kind of structure of middle frequency furnace induction coil; Comprise induction coil 10, in induction coil 10 peripheries several location-plates 20 are set, location-plate 20 is fixedly connected on the outside of induction coil 10 through bolt 30; Be used to keep the turn-to-turn distance of induction coil 10, make not contact between induction coil 10 circles and the circle.Induction coil 10 tops are provided with short-circuited conducting sleeve 40, and this short-circuited conducting sleeve 40 is fixed on the upper end of location-plate 20 through bolt 30, and and induction coil 10 between keep gap 101, this gap 101 is not less than the turn-to-turn distance of induction coil 10.The external diameter of this short-circuited conducting sleeve 40 is identical with the external diameter of induction coil 10, and gap 101 distances between short-circuited conducting sleeve 40 and the induction coil 10 and the turn-to-turn of induction coil 10 are apart from identical.Can effectively reduce the induction coil leakage field like this, at utmost protect the induction coil circumferential component normally to move.
In conjunction with Fig. 2 and Fig. 3, short-circuited conducting sleeve 40 is the non-closed becket that copper pipe surrounds, and width is set more than or equal to 3 centimetres fracture 401 on this becket.Two ends at short-circuited conducting sleeve 40 are welded with diaphragm seal 402 respectively, and sealing sheet 402 is used to seal short-circuited conducting sleeve 40.Two ends of short-circuited conducting sleeve 40 are respectively equipped with delivery port 501 and water inlet 502.
As preferably, delivery port 501 outwards extends in parallel with the circumferencial direction of water inlet 502 along short-circuited conducting sleeve 40, and minimum spacing is smaller or equal to 10 centimetres between delivery port 501 and the water inlet 502.Can guarantee like this that when middle frequency furnace is worked the cooling water in the short-circuited conducting sleeve 40 can fully circulate, guarantee the radiating effect of short-circuited conducting sleeve 40.
When adopting the middle frequency furnace work of the utility model, induction coil 10 energisings, inner water flowing; The electromagnetic action of its generation is in smelting furnace, and fusing is as for the metal of inside furnace, because the induction coil upper end is provided with short-circuited conducting sleeve 40; 40 water flowing no powers of short-circuited conducting sleeve; The electromagnetism that like this induction coil 10 is made progress cuts off, and the heat that short-circuited conducting sleeve 40 is produced by electromagnetic effect cools off through its inner recirculated cooling water, has effectively protected the equipment of induction coil top.Because the equipment of induction coil top the hot phenomenon of generating heat can not occur, the service behaviour of induction coil is provided, prolonged the working life of middle frequency furnace.
