Abstract
The utility model relates to an intermediate frequency electric furnace magnet yoke which includes an iron core and a heat radiation box. The iron core is made by superposing multiple iron sheets. The heat radiation box is fixedly arranged on the outside of the iron core. The intermediate frequency electric furnace magnet yoke is characterized in that the two ends of an outer side of the heat radiation box are provided with metal plates; the total length of the metal plates is smaller than or equal to the length of the heat radiation box. Compared with the prior art, the intermediate frequency electric furnace magnet yoke is provided with the metal plates on the positions near a connecting terminal, so the electromagnetic interference of the connecting terminal to the magnet yoke is effectively shielded, at the same time, the metal plates can effectively help the heat radiation box to play the heat radiation function, and consequently the heat radiation performance of the magnet yoke is greatly improved.
Description
Technical field
The utility model relates to a kind of middle frequency furnace yoke, especially relates to a kind of controllable silicon middle frequency furnace yoke.
Background technology
Middle frequency furnace is a kind of supply unit that power frequency 50HZ alternating current is changed into intermediate frequency (300HZ is above to 10000HZ); The three-phase main-frequency alternating current, become direct current after the rectification, become adjustable electric current of intermediate frequency to direct current again; Supply is by the intermediate frequency alternating current that flows through in electric capacity and the induction coil; In induction coil, produce the highdensity magnetic line of force, and the metal material that holds in the cutting induction coil, very big eddy current in metal material, produced.This eddy current has some character of electric current of intermediate frequency equally, that is, the free electron of metal self will produce heat having in the metallic object of resistance to flow.Yoke is fixed on the body of heater outside as the vitals of middle frequency furnace along body of heater circumference method.
In actual use, because the abnormal heating situation often appears near the yoke the middle frequency furnace binding post, should normally move by first middle frequency furnace.
Summary of the invention
The utility model provides a kind of middle frequency furnace yoke that can effectively prevent near the yoke abnormal heating of middle frequency furnace binding post to deficiency of the prior art.
For solving the problems of the technologies described above, the utility model is able to solve through following technical proposals:
The middle frequency furnace yoke comprises iron core and heat radiation case that iron plate is formed by stacking, and said heat radiation case is fixed on the outside of iron core, it is characterized in that, two ends, the said heat radiation case outside are provided with metallic plate, and the length of said metallic plate is smaller or equal to the length of said heat radiation case.
In the technique scheme, said metallic plate is the copper coin of long 40cm, thick 3mm, and the width of the width of this copper coin and said heat radiation case is suitable.
The beneficial effect of the utility model is: compared with prior art; The two ends of closing on binding post one side in the middle frequency furnace yoke are provided with metallic plate; Effectively shielded the electromagnetic interference of binding post to yoke; The metallic plate case performance heat sinking function that can effectively help to dispel the heat has simultaneously improved the heat dispersion of yoke greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the enlarged drawing of A-A place cutaway view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
In conjunction with Fig. 1 and Fig. 2, the middle frequency furnace yoke comprises that some tagger stacks form iron core 10, and iron core 10 both sides are provided with heat radiation case 20, and this heat radiation case is used for dispelling the heat to iron core when middle frequency furnace is worked.The two ends of closing on a side of binding post at heat radiation case 20 are welded with metallic plate 30, and as preferably, this metallic plate is a copper coin.
The length of this metallic plate 30 is no more than the length of radiator, and its thickness is 3mm, and the width of its width and radiator is suitable.
As preferably, metallic plate 30 is the copper coin of long 40cm, thick 3mm, and the width of the width of this copper coin and said heat radiation case 20 is suitable, and this metallic plate also can be through being bolted on the case that dispels the heat.
Compared with prior art, the two ends of closing on binding post in the middle frequency furnace yoke are provided with metallic plate, have effectively shielded the electromagnetic interference of binding post to yoke, and the metallic plate case performance heat sinking function that can effectively help to dispel the heat has simultaneously improved the heat dispersion of yoke greatly.
