Abstract
The utility model discloses a high temperature is induction coil for graphitizing furnace, including being the hollow copper tube that the heliciform was encircleed, its characterized in that: the outer winding of hollow copper tube has insulation cloth, and the insulation cloth surface scribbles the insulation and paints, the material is pour to insulating paint outside, pours the material surface and still scribbles insulating paint. Induction coil high temperature during operation, insulation cloth, insulating paint, pour the material can have priority prevent to strike sparks between the coil, the emergence of short circuit phenomenon. The fortifying fibre is built the material and because of the crackle quantity of stress generation, is improved and build body intensity, extension induction coil life through " pinning effect " effective reduction. Simultaneously, the induction coil of integral type takes out more easily and places when maintaining the change.
Description
Technical field
The utility model relates to induction coil, especially a kind of high temperature graphitization stove induction coil.
Background technology
Induction coil is the core component of high temperature graphitization stove, is also essential element, is to be formed by spirality coiling by hollow copper.At high temperature graphitization stove duration of work, induction coil energising produces magnetic field, produces induced current, make workpiece self by eddy heating for heating to temperature required in blank.Usually, the anti-sparking of induction coil puts that to burn processing method be brush insulating varnish after being wound around glass wool cloth or other insulating material thereon, and builds a circle fire proofing tile therein by laying bricks or stones.But the burner hearth maximum temperature of high temperature graphitization stove is up to 3000 DEG C, in use easily there is scorification punching phenomenon in fire proofing tile, and each maintenance all needs again to build by laying bricks or stones, and glass wool cloth and insulating varnish at high temperature the life-span reduces greatly, therefore easily occur that induction coil burns, leak and big fire phenomenon, produce dangerous.
Utility model content
For overcoming the deficiency of the problems referred to above, the utility model provides a kind of high temperature graphitization stove induction coil.
For achieving the above object, the utility model adopts following technical scheme: a kind of high temperature graphitization stove induction coil, comprise in the shape of a spiral around hollow copper tubing, it is characterized in that: outside described hollow copper tubing, be wound with empire cloth, empire cloth outer surface scribbles insulating paint, built pouring material outside described insulating paint, pouring material surface also scribbles insulating paint.
Preferred: containing fortifying fibre in described pouring material.
Preferred: described pouring material is the mixture of one or more compositions in aluminium oxide, silicon dioxide, alumina cement, carborundum, magnesium oxide, calcium chloride.
The utility model beneficial effect is: during induction coil hot operation, and empire cloth, insulating paint, pouring material preferentially can prevent the generation of sparking, short circuit phenomenon between coil.Fortifying fibre effectively reduces by " pinning effect " crack number that pouring material stress produces, and improves and waters building body intensity, extends induction coil useful life.Meanwhile, the induction coil of integral type more easily takes out when safeguarding and changing and places.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
In figure: 1-hollow copper tubing, 2-empire cloth, 3-insulating paint, 4-castable.
Embodiment
Below in conjunction with accompanying drawing, the utility model and embodiment thereof are described in further detail.
Fig. 1 is a preferred embodiment of the present utility model.As shown in the figure: a kind of high temperature graphitization stove induction coil, especially vertical high-temperature graphitizing furnace, horizontal-type high temperature graphitizing furnace induction coil, comprise in the shape of a spiral around hollow copper tubing 1, the outer uniform winding of described hollow copper tubing 1 has empire cloth 2, empire cloth 2 outer surface scribbles insulating paint 3, built pouring material 4 outside this insulating paint 3, this pouring material 4 is the castable that surface also scribbles insulating paint.
Containing fortifying fibre in described pouring material 4, fortifying fibre adds when pouring material 4 stirs, and is evenly distributed on castable 4 inside by building.
Described pouring material is the mixture of one or more compositions in aluminium oxide, silicon dioxide, alumina cement, carborundum, magnesium oxide, calcium chloride.
When induction coil hot operation, empire cloth 2, insulating paint 3, pouring material 4 preferentially can prevent the generation of sparking, short circuit phenomenon between coil.Fortifying fibre effectively reduces by " pinning effect " crack number that pouring material 4 stress produces, and improves and waters building body intensity, extends induction coil useful life.Meanwhile, the induction coil of integral type more easily takes out when safeguarding and changing and places.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
Claims (2)
1. a high temperature graphitization stove induction coil, comprise in the shape of a spiral around hollow copper tubing, it is characterized in that: be wound with empire cloth outside described hollow copper tubing, empire cloth outer surface scribbles insulating paint, built pouring material outside described insulating paint, pouring material surface also scribbles insulating paint.
2. high temperature graphitization stove induction coil according to claim 1, is characterized in that: described pouring material is the one in aluminium oxide, silicon dioxide, alumina cement, carborundum, magnesium oxide, calcium chloride.
