Manufacturing process of induction coil of induction heating furnace

The inductor is a working coil. When the alternating current passes through the coil, an alternating magnetic field is generated around the wire. The metal workpiece in the magnetic field generates electromotive force due to electromagnetic induction, and the eddy current heats the workpiece. The coil has a mechanical The force acts on the workpiece. Need to meet the requirements of the heating range of the workpiece, the temperature of the heating zone is uniform, and the cooling is uniform.

The specific process of the induction coil manufacturing process of the induction heating furnace is as follows: <3 overlap-wound alkali-free glass ribbon

Dipping insulation varnish: preheat the coil covered with insulation in an electric furnace or a hot air drying box, and then dip it with organic insulation varnish for 15 minutes. If there are many bubbles in the paint during the dipping process, the dipping time should be prolonged. Generally, the dipping should be dried for three times: in an electric furnace or a hot air drying box, the furnace temperature should not be higher than 50 degrees when the coil is installed. The temperature rises at a rate of 15 degrees/h, and when it reaches 100-110 degrees, it is dried for 20 hours, but it should be baked until the lacquer wax does not stick to the hands.
