Abstract
The utility model relates to a special device for replacing an inductor in a smelting induction furnace, in particular to a special cooling water jacket for a low-power inductor in a core-type induction furnace. The cooling water jacket is a closed rectangular box; a cooling water pipe is arranged in the box; both the inlet and the outlet of the cooling water pipe are arranged outside the box; andthe cooling water pipe is designed into S shape. The special cooling water jacket provided by the utility model can reduce the temperature of molten metal around the cooling water jacket to the solidification temperature, so that the molten metal can be solidified into metal, the generated solid metal can block the molten metal in a molten pool to form a temporary inner wall of the furnace, so asto provide a temporary operation space for replacing the inductor, therefore, the replacement for the inductor is not affected by the overall state of a furnace body; while the molten metal in the induction furnace can be kept in a normal molten state, after the replacement, the production can be recovered, thereby realizing the free replacement of a single inductor.

Smelting industry generally adopts induction furnace as apparatus for melting metal at present, power is usually used in the melting of metal less than the low-power inductor core-type induction furnace of 90KW, core-type induction furnace generally comprises body of heater and a plurality of inductor, its structure as shown in Figure 2, its a plurality of inductors 2 be individually fixed in body of heater 4 around, molten metal in the body of heater 4 flows out by 3 casting of disk casting machine, inductor 2 is that non-dismountable integral body is constructed the formula structure with body of heater 4, molten metal and the molten metal in inductor 2 channels in body of heater 4 burner hearths flow mutually, when certain inductor wherein breaks down or leaks metal, can only under the situation of not removing inductor, handle its method of repairing, to leak metal serious when inductor, in the time of can't repairing, just this inductor is scrapped and core-type induction furnace continuation use, after if the inductor of this core-type induction furnace is scrapped more than two, just can't reach instructions for use, then must be with this core-type induction furnace brickwork again, cause this core-type induction furnace short service life, the maintenance cost height influences quantity-produced and normally carries out.Therefore, how can aborning the written-off inductor of core-type induction furnace be changed to prolong core-type induction furnace service life, be to need the difficult problem further explored.
The utility model content
The purpose of this utility model is to provide a kind of core-type induction furnace low-power inductor to change special cooling water jacket thereof, and it can make the molten metal around it solidify.
The technical solution of the utility model is:
A kind of core-type induction furnace low-power inductor is changed special cooling water jacket thereof, it is characterized in that: it is provided with cooling water pipe for the closed rectangular box in the casing, the import and export of described cooling water pipe all are arranged at outside the casing.
As to further improvement of the utility model, described cooling water pipe is snakelike cooling water pipe.
As to further improvement of the utility model, described casing is the flat cuboid, and the many places bending in same plane of described cooling water pipe places in the casing.
As to further improvement of the utility model, described casing length is 1000mm～1200mm, and width is 55mm～60mm, highly is 2000mm～2500mm, and the casing wall thickness is 8～12mm.
As to further improvement of the utility model, the pressure of cooling water is 0.4Mpa～0.8Mpa in the described cooling water pipe.
Using method of the present utility model is:
The step that adopts the core-type induction furnace low-power inductor to change special cooling water jacket thereof replacing inductor of cored induction electric furnace is:
Step 1: with the core-type induction furnace Control for Kiln Temperature at 430 ℃～450 ℃;
Step 2: special cooling water jacket thereof is inserted along place, furnace wall, molten bath in the pairing core-type induction furnace body of heater of inductor to be replaced, pass to the cooling water of 0.4Mpa～0.8Mpa in the cooling water pipe, its molten metal is on every side solidified;
Step 3: remove inductor to be replaced;
Step 4: standby inductor butt joint is installed, close the cooling water of special cooling water jacket thereof;
Step 5: the core-type induction furnace furnace temperature is risen to about 470 ℃～480 ℃, make special cooling water jacket thereof solid metal fusing on every side, take out special cooling water jacket thereof, recover to send electricity, progressively booster tension is to the ordinary production state.
The beneficial effects of the utility model are:
The special cooling water jacket thereof that the utility model provides can make the molten metal temperature around it drop to setting temperature, be frozen into solid metal, when treating that this part solid metal can intercept the molten metal in the core-type induction furnace body of heater molten bath and the molten metal in the inductor, promptly become interim stove inwall, provide an interim working space for changing inductor, make more changing jobs of inductor not be subjected to the influence of body of heater integrality, and the molten metal in the core-type induction furnace body of heater molten bath can maintain normal molten condition, after work to be replaced is finished, can resume production, realize freely changing of the single inductor of core-type induction furnace.
The utility model has solved the problem that core-type induction furnace is repaiied in frequent, can save a large amount of maintenance costs, for the continuous production of equipment provides guarantee.
