    1分钟看懂中频炉线圈的绕制方法

    1、中频炉线圈退火。在绕制感应线圈之前,先对矩形纯紫铜管进行退火。将纯铜管在650~700℃保温30~40分钟,然后在20~30℃的水中快速冷却。

    2、中频炉线圈绕制。将矩形纯紫铜管绕制成各种仿形感应线圈。在中频炉线圈绕制时应采用铁模或木模,考虑到矩形铜管绕制后有回弹量,故应使模具的尺寸稍小于所要求的尺寸。当绕制半径较小时,应进行加热绕制,即在绕制时用乙炔火焰去烘烤弯曲部位的纯铜管。

    3、中频炉线圈校正。将绕制后的感应线圈校正到所需要的尺寸,并用夹具压紧。

    4、中频炉感应线圈绕制后退火温度、时间与方式和纯铜管相同。

    5、中频炉线圈水压试验。在感应线圈的纯铜管中通入压力为给水设计压力1.5倍的水或空气,检验纯铜管与管子接头处是否有漏水现象。

    6、中频炉线圈包绝缘层。在纯铜管上1/3重叠绕无碱玻璃丝带。

    7、中频炉线圈浸绝缘漆。将包了绝缘层的感应线圈在电炉或热风烘干箱中预热,然后浸有机绝缘漆,浸漆时间为15分钟。在浸漆过程中如果漆中气泡很多,则应延长浸漆时间,一般浸漆三次。

    8、中频炉线圈烘干。在热风烘干箱中进行。中频炉感应线圈装炉时炉温不应高于50℃,并以15℃/h的速度升温,至100~110℃时烘干20h,但应以烘至漆膜不粘手为止。

    Understand the winding method of induction melting furnace coil in 1 minute

    1. Annealing of induction melting furnace coils. Before winding the induction coil, the rectangular pure copper tube is annealed. Keep the pure copper tube at 650~700℃ for 30~40 minutes, and then quickly cool it in water at 20~30℃.

    2. Induction melting furnace coil winding. Wind the rectangular pure copper tube into various profiling induction coils. Iron or wooden molds should be used when winding the coils of the induction melting furnace. Considering the springback of the rectangular copper tube after winding, the size of the mold should be slightly smaller than the required size. When the winding radius is small, heating winding should be performed, that is, acetylene flame is used to bake the pure copper tube at the bending part during winding.

    3. Induction melting furnace coil correction. Correct the wound induction coil to the required size and press it with a clamp.

    4. The annealing temperature, time and method after winding the induction coil of the induction melting furnace are the same as those of the pure copper tube.

    5. Induction melting furnace coil water pressure test. Pass water or air with a pressure 1.5 times the design pressure of the feedwater into the pure copper tube of the induction coil, and check whether there is water leakage at the joint between the pure copper tube and the pipe.

    6. The coil of the Induction melting furnace  is covered with an insulating layer. On the pure copper tube, 1/3 overlap and wrap the alkali-free glass ribbon.

    7. The coil of the induction melting furnace is impregnated with insulating varnish. The induction coil covered with the insulating layer is preheated in an electric furnace or a hot air drying box, and then dipped in an organic insulating paint for 15 minutes. If there are many bubbles in the paint during the dipping process, the dipping time should be extended, generally three times.

    8. Induction melting furnace  coil drying. It is carried out in a hot air drying box. When the induction melting furnace is installed, the temperature of the induction coil should not be higher than 50℃, and the temperature should be raised at a rate of 15℃/h, and it should be dried for 20h at 100~110℃, but it should be baked until the paint film does not stick to the hands.
