Description
Technical field
The utility model is related to medium-frequency induction furnace faraday's electromagnetism short-circuit ring structure fields, and in particular to one kind have every
The intermediate frequency furnace load coil of magnetic effect.
Background technology
The magnetic flux of Medium frequency induction circle fusion zone and induction coil outside magnetic circuit and electric furnace shell along stove constitute closed circuit, stove
Outer circle, bottom and the upper cover plate part of shell because across alternating flux due to generate induced current, box hat electric furnace be arranged by silicon steel sheet
Yoke outside induction coil made of closed assembly.The bottom of electric furnace shell, upper cover plate part generate inductive loop because of no magnetic screen, are
It prevents upper and lower cover plates since induced current is generated heat, using more efficient short-circuit loop technique, further decreases the loss of electric furnace
With improve utilization rate of electrical, be a great problem urgently to be resolved hurrily.
Utility model content
For problems of the prior art, have in magnetism isolating effect the purpose of this utility model is to provide a kind of
Frequency induction furnace load coil is solved using the leakage field area coverage for increasing short-circuited conducting sleeve at a distance from relative to induction coil
Problem certainly exists in the prior art, realizes preferably covering and has reached energy-efficient effect to reduce leakage field.
To achieve the above object, the utility model uses following technical scheme：
A kind of intermediate frequency furnace load coil with magnetism isolating effect, the load coil includes the line of induction
Circle, the induction coil are respectively arranged with short-circuited conducting sleeve and lower short-circuited conducting sleeve, the upper short-circuited conducting sleeve and lower short circuit over and under
Ring is cast in respectively in cylinder and lower cylinder, keeps setting between upper short-circuited conducting sleeve and lower short-circuited conducting sleeve and the upper and lower end face of induction coil
Set a distance；It is provided with yoke between the outside and furnace shell of induction coil.
Further, the outer diameter for the circle that yoke described in the outer diameter ratio of the upper short-circuited conducting sleeve and lower short-circuited conducting sleeve is formed is big.
Further, the internal diameter of the upper short-circuited conducting sleeve and lower short-circuited conducting sleeve is equal to the central diameter of the induction coil.
Further, the setpoint distance not less than the induction coil turn-to-turn away from.
The utility model has following advantageous effects：
After load coil with the application is applied to medium-frequency induction furnace operation, lower casing and yoke on furnace body
Whole fever reduce, while coil, up and down without installing water cooled coil additional, energy consumption is brighter than the medium-frequency induction furnace of non-such structure
It is aobvious energy saving, illustrate that this medium-frequency induction furnace faraday's electromagnetism short-circuited conducting sleeve works well, in addition, short-circuited conducting sleeve is in actual production installation
It is cooling, simple and practicable to reduce water route, is operated convenient for actual production and reduces potential faults point.
Description of the drawings
Fig. 1 is the stereochemical structure structural schematic diagram (cylinder in removal) of the utility model embodiment；
Fig. 2 is the stereochemical structure structural schematic diagram of the utility model embodiment.
Specific implementation mode
Hereinafter, the utility model will be described more fully with reference to the accompanying drawings, shown in the drawings of showing for the utility model
Example property embodiment.However, the utility model can be presented as a variety of different forms, it is not construed as being confined to describe here
Exemplary embodiment.But these embodiments are provided so that this disclosure will be thorough and complete, and by the utility model
Range is fully communicated to those skilled in the art.
As shown in Figs. 1-2, the utility model provides a kind of intermediate frequency furnace load coil with magnetism isolating effect,
The load coil includes induction coil 1, and induction coil 1 is respectively arranged with short-circuited conducting sleeve 2 and lower short circuit over and under
Ring 5, upper short-circuited conducting sleeve 2 and lower short-circuited conducting sleeve 5 are cast in respectively in cylinder 3 and lower cylinder 6, upper short-circuited conducting sleeve 2 and lower short-circuited conducting sleeve 5 and sense
It answers and keeps setpoint distance between the upper and lower end face of coil 1 (distance is related with frequency according to designed furnace body tonnage)；Induction coil 1
Outside and furnace shell between be provided with yoke 4.
The outer diameter of upper short-circuited conducting sleeve 2 and lower short-circuited conducting sleeve 5 is bigger than the outer diameter for the circle that yoke 4 is formed.Sense can be effectively reduced in this way
The leakage field of coil 1 is answered, 1 circumferential component normal operation of induction coil is utmostly protected.The fixation of yoke 4 is enclosed in induction coil 1
Outside and furnace shell between, constitute induction coil 1 outer magnetic shield circuit, in addition short-circuited conducting sleeve 5 under short-circuited conducting sleeve 2 and furnace bottom on fire door
Shielding, avoid and shield 1 outer magnetic flux of induction coil by furnace shell, furnace bottom shell and fire door cover board induction fever, substantially reduce
The no-load loss of electric furnace.
The internal diameter of upper short-circuited conducting sleeve 2 and lower short-circuited conducting sleeve 5 is equal to the central diameter of induction coil 1 (in the outer diameter and internal diameter of induction coil 1
Between).
Setpoint distance not less than induction coil 1 turn-to-turn away from.
Magnetic flux path when the application works according to the magnetic flux path of Medium frequency induction circle with it at different frequencies, using adding
The leakage field area coverage of big short-circuited conducting sleeve solves the problems, such as to exist in the prior art at a distance from relative to induction coil, realizes more
Good is covered in reduction leakage field；Energy-efficient effect is reached.
It is described above simply to illustrate that the utility model, it is understood that the utility model is not limited to the above implementation
Example, the various variants for meeting the utility model thought both are within the protection scope of the present invention.
