Abstract
The utility model discloses an induction coil apparatus for a medium-frequency induction melting furnace. The induction coil is characterized in that, a coil, an upper water cooling coil and a lower water cooling coil are all produced by winding copper tubes; the upper water cooling coil is arranged above the coil, and the lower water cooling coil is arranged below the coil; a shielding ring is arranged on the top of the upper water cooling coil, and a shielding ring is arranged on the bottom of the lower water cooling coil; the coil, the upper water cooling coil, the lower water cooling coil and the shielding rings are coated by at least one layer of mica glass fiber tapes, and are peripherally provided with at least one insulating column; a copper bar and at least one water nozzle are arranged on the coil, the upper water cooling coil, the lower water cooling coil and the shielding rings; and at least one screw nut is arranged on the insulating column. According to the utility model, the water cooling coils are produced by winding copper tubes as same as that of the coil, saving both labor and time for winding, and during a heating process, the heat-expansion and cold-contraction of the whole coil is consistent and synchronous, preventing accidents caused by different internal stresses.
Description
Technical field
The utility model relates to a kind of medium frequency induction melting furnace induction coil device.
Background technology
The medium frequency induction melting furnace induction coil adopts coiling copper pipe (energising water flowing) to add the method for coiling stainless steel tube (water flowing) always, in actual use, after coil is heated, because copper pipe and stainless steel tube thermal coefficient of expansion are different, cause the distortion of coil support bar and stamp mass, generation causes the accident.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present utility model is to provide a kind of medium frequency induction melting furnace induction coil device of practicality, the water-cooled circle adopts the copper pipe coiling the same with coil, saving of work and time in coiling, in heating process, expanding with heat and contract with cold of whole winding is consistent, is synchronous, avoided the different accident that causes of internal stress.
For reaching above-described purpose, a kind of medium frequency induction melting furnace induction coil device of the present utility model is taked following technical scheme:
A kind of medium frequency induction melting furnace induction coil device, comprise coil, last water-cooled circle, following water-cooled circle, the insulation column, shading ring, bolt and nut, the glass bonded mica silk ribbon, water nozzle and copper bar, it is characterized in that, described coil, last water-cooled circle and following water-cooled circle all adopt the copper pipe coiling, the coil top arranges the water-cooled circle, the coil below arranges down the water-cooled circle, the described water-cooled circle top of going up arranges shading ring, described water-cooled circle down bottom arranges shading ring, described coil, last water-cooled circle, the female glass tape of at least one stratus of parcel on following water-cooled circle and the shading ring, coil, last water-cooled circle, at least one eradication edge column is set around following water-cooled circle and the shading ring, coil, last water-cooled circle, copper bar and at least one water nozzle are set on following water-cooled circle and the shading ring, on the described insulation column at least one bolt and nut are set.
Adopt as above the utility model of technical scheme, have following beneficial effect:
The water-cooled circle adopts the copper pipe coiling the same with coil, saving of work and time in coiling, and in heating process, expanding with heat and contract with cold of whole winding is consistent, is synchronous, avoided the different accident that causes of internal stress.
