Induction Heating
Induction heating is a process that is used to harden or soften conductive materials. Conductivity is the amount that a specific material is able to transfer electricity. The amount is calculated by the ratio of current density in the material to the electric field that causes the flow of the current. When an electrical current is alternating and applied to a transformer, a magnetic field with occur. By applying Faraday’s Law, if the secondary of the transformer is located within the magnetic field, an electric current will be induced.
In induction heating, a solid state radio frequency power supply sends an AC current through an inductor. Radio frequency is any type of electromagnetic wave that lies within a specific range of frequency. The range is from 3 kHz to 300GHz. A kHz, or kilohertz is a unit of current or electromagnetic wave frequency equal to one thousand hertz 1,000 Hz. A GHz is a unit that equals to one billion hertz per second. An AC current is an electric current in which the flow of electric charge periodically reverses direction. An inductor is a coil or reactor that is a passive, and has two terminal electrical components. It resists changes in the electric current passing thought it. Primary voltage is the voltage that is applied to terminal of primary winding of a transformer. A secondary voltage is a coil winding supplying the output voltage. This is normally the workpiece that needs to be heated. Once the metal part is placed within the inductor it enters the magnetic field, circulating a current. The current flow against the electrical resistance of metal. This generates precise and localized heat without direct contact. The heating occurs with both magnetic and nonmagnetic parts.
