Induction coil introduction


  Induction heating coils are also called inductors, electromagnetic transducers, and the like. It is an energy output device for induction heating equipment such as high frequency machines and intermediate frequency machines. In order to ensure the heating speed and efficiency, the parameters (number of turns), diameter, shape, size and other parameters must meet the requirements of impedance matching conditions and workpiece processes. Relatively speaking, the larger the diameter of the induction coil, the fewer the number of turns; the smaller the diameter, the more the number of turns.
Commonly used sensors include external surface heating sensor, internal hole heating sensor, flat heating sensor, universal heating sensor, special heating sensor, single heating sensor, composite heating sensor, melting furnace, etc. Wait.
In the selection of materials, the high resistivity copper should be selected, and the specification and wall thickness should meet the requirements of the maximum working current. In order to avoid the ignition of the induction coil and the workpiece, the induction coil is ignited, and the anti-magnetic saturation causes damage and influence on the machine or the workpiece. In the production, not only must design the sensing scheme, determine the shape of the induction coil, and calculate the main parameters. Also need to choose materials such as insulation, insulation, insulation and protection. Such as high temperature insulation casing, high temperature insulation cotton, quartz tube, graphite tube, silica gel and refractory materials.

The performance of the coil of the medium and high frequency induction heating equipment directly affects the effective output power, work efficiency, stability reliability and service life of the equipment. Therefore, each sensor should be strictly designed and manufactured, and even require experimental demonstration.

Heating principle of induction coil


 The induction heating device is a three-phase power frequency alternating current, which is rectified into a direct current, and then the direct current is converted into an adjustable current, and an alternating current flowing through the capacitor and the induction coil is supplied to generate a high density in the induction coil. The magnetic lines of force and the cutting of the metal material contained in the induction coil create a large eddy current in the metal material. This eddy current also has some properties of high frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. For example, a metal cylinder is placed in an induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil. The temperature of the energized coil itself is already low, but the surface of the cylinder is heated to redness or even melt. And the speed of redness and melting can be achieved by adjusting the frequency and current intensity. If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same. The cylinder is heated and melted without generating harmful gases or strong light to pollute the environment.
