Abstract
The utility model relates to a metal melting device, in particular to an inductor of cored induction furnace, which comprises an inductor case, an inductor coil, an inductor furnace liner, an iron core and a melting channel, wherein the inductor is connected with furnace body via a flange; the damaged inductor can be freely exchanged while the damaged inductor is not repaired in furnace body. Since the inductor is hinged with the furnace body via a flange, the inductor can be freely exchanged without being repaired in furnace, and the melting channel is hollow after demolding, the inner wall of the melting channel is smooth and flat, thus being beneficial for flowing zinc liquid and avoiding breakage in thermal expansion; the utility model utilizes cast material to replace water glass or dry material, the fireproof material has high strength and compact structure to resolve zinc leakage problem of the inductor and prolong service life.
Description
Technical field
The utility model relates to a kind of apparatus for melting metal, particularly a kind of inductor of cored induction electric furnace.
Background technology
At present, smelting industry generally adopts electric induction furnace as apparatus for melting metal, inductor is a vitals of line frequency furnace, inductor is equivalent to the transformer of a ribbon core, metal is equivalent to transformer one circle secondary coil in the channel, induction coil in the inductor is equivalent to primary winding, when passing to power current to primary winding, metal heating, fusing in the channel, then by conduction, convection current etc. metal in the heat transferred burner hearth, make that metal constantly is heated in the molten bath, melt.Line frequency furnace is exactly the electromagnetic induction by inductor, makes the furnace charge heating, thereby reaches the purpose of furnace charge fusing and insulation.
Power is the melting that the low-power inductor core-type induction furnace of 90KW is usually used in zinc, usually the low-power inductor of core-type induction furnace is to link together non-removable with body of heater, electric furnace inductor leaks can not be changed after zinc damages at any time, the replacing of electric furnace inductor will with body of heater in repair simultaneously and carry out.This kind electric furnace inductor is general to adopt built-in zinc ring to do channel, and water frit tamping forms; Or adopt built-in zinc ring to do channel, and ring adds dry type material tamping and forms in making of copper sheathing, and fusing forms channel to the zinc ring under the electrically heated situation sending.The zinc ring of this kind inductor expands when being heated, and easily makes on the coagulation of inductor to ftracture, and service life is short.
The utility model content
The purpose of this utility model is to provide a kind of novel inductor for core-containing induction furnace, it is applicable to the core-type induction furnace of being made up of a plurality of inductors, satisfy the instructions for use that each inductor can be removed separately, change, have dismounting, change conveniently advantages such as long service life.
The technical solution of the utility model is: a kind of inductor for core-containing induction furnace, and it comprises inductor housing, inductor coil, inductor furnace lining, iron core and channel, wherein, described inductor housing is provided with and core-type induction furnace body of heater flange connecting.
As to further improvement of the utility model, the material of described inductor furnace lining is for watering material feeding, describedly waters material feeding and is: high alumina castable or corundum pouring material, the Al of high alumina castable
2O
3Content is 75%-90%, the Al of corundum pouring material
2O
3Content is＞90%.
As to further improvement of the utility model, the channel of described inductor is the annular hollow passageway in the inductor furnace lining.
As to further improvement of the utility model, the cross section of the channel of described inductor is square.
The beneficial effects of the utility model are:
First, because it in the inductor furnace lining is hollow passageway that the utility model is designed to the channel of inductor, and need not to be provided with in the prior art zinc ring through inductor, make each inductor separate, can dismantle, owing to be to be connected by flange between inductor and the body of heater, therefore, can realize that inductor is independently detachable, and can under the situation of not carrying out repairing in the stove, freely change.The time of changing an inductor influence production can not surpass 8 hours, and the time of carrying out repairing in the stove is taken more than one month at least.
The second, be hollow after the channel demoulding of this kind low-power inductor, there is not the problem of expanded by heating; And the channel of traditional low-power inductor is the zinc ring, does not need the demoulding, is solid, has zinc ring expanded by heating and makes the problem of inductor furnace lining cracking;
The 3rd, the material employing of furnace lining is watered material feeding and is replaced waterglass material of the prior art or dry type material, and this kind furnace lining intensity is good, and compact structure avoids zinc liquid to infiltrate in the furnace lining body, has solved the problem that inductor leaks zinc;
The 4th, the channel inner wall smooth of this kind structure is smooth, helps flowing of zinc liquid;
The 5th, this kind low-power inductor long service life, all reach more than 1 year service life.

Fig. 2 is a B-B sectional structure schematic diagram of the present utility model.
Wherein: 1-inductor adpting flange; The 2-channel; 3 iron cores; 4 inductor coils; 5-inductor furnace lining; 6-inductor housing.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment 1:
A kind of inductor of cored induction electric furnace, it is applicable to the core-type induction furnace of being made up of a plurality of inductors, comprise inductor housing 6, inductor coil 4, inductor furnace lining 5, iron core 3 and channel 2, inductor housing 7 is connected by inductor flange 1 with the core-type induction furnace body of heater.
The material of inductor furnace lining 5 is Al
2O
3Content is 75% high alumina castable, and the channel 2 of inductor is the annular hollow passageway in the inductor furnace lining 5, is hollow-core construction, and the cross section of channel 2 is square.
After tested, inductor current is 286A, and actual power is 89.4kw.Operation was also very normal after inductor reached 14 months service life.
Comparative Examples 1
Adopt built-in zinc ring to do channel, use the waterglass material to make the detachable advection type low-power inductor of furnace lining tamping, the technical data of testing in running is as follows: inductor current 318A, actual power 74.5kw, 3 months service life.
