How exactly does induction heating work? help to have a basic understanding of the principles of electricity. When an alternating electrical current is applied to the primary of transformer, an alternating magnetic field is primary of a transformer. an alternating magnetic field is created. According to Faraday's Law, if the secondary of the transformer is located within the magnetic field, an electric current will be induced.
In a basic induction heating setup shown at right, a solid state RF power sully sends am AC current through an inductor (often a copper coil), and the part to be heated (the workpiece) is placed inside the inductor. The inductor serves as the transformer primary and the part to be heated becomes within the inductor and enters the magnetic field, circulating eddy currents are induced within the part.
As shown in the second diagram, these eddy currents flow against the electrical resistivity of the metal, generating precise and localized heat without any direct contact between the part and the inductor. This heating occurs with both magnetic and non-magnetic parts, and is often referred to as the "Joule effect", referring to JouIe's first law - a scientific formula expressing the relationship between heat produced by electrical current passed through a conductor.
Secondarity, addittional heat is produced within magnetic parts through hysteresis - internal friction that is created when magnetic parts pass through the inductor. Magnetic materials naturally offer electrical resistance to the rapidly changing magnetic fields within the inductor. This resistance produces internal friction which in turn produces heat.
In the process of heating the material, there is therefore no contact between the inductor and the part and neither are there any combustion gases. The material to be heated can be located in a setting isolated from the power supply; submerged in a liquid, covered by isolated substances, in gaseous atmospheres or even in a vacuum.
Induction heating has the advantages of high heating speed, high producing effect, no(less) oxidation. no(less) decarburization of the heated work pleces. It can easily realize mechaninzation, automation, and flow-line production. It is also energy smart, no public harm, can improve the working environment significantly As a result, it is widely used to industrial processes like metal melting. hot forging/forming, heat treating braze welding, etc.

How to select induction heating equipment?
Both "Input Power" and "Oscillation frequency" of the power supply are the key parameters when selecting induction heating equipment.
The higher the frequency is, the less the heating depth into workpiece; The lower the frequency, the deeper heating will penetrate. So you need to select induction heating machine with suitable output frequency to get best heating efficiency.
The heating speed is determined by power, select suitable power according to the weight of workpiece to heat, temperature to reach and requirement to heating speed.
- Proficient way of heating accurately at the particular area of work.
- Identical result with an recognized heating cycle.
