Principle of High Frequency Induction Heating
The operation of a high-frequency induction heater involves the induction coil generating a powerful magnetic field that creates polar instantaneous changes. When the metal item requiring heat treatment is positioned within the coil, the magnetic field penetrates the metal, producing a strong high-frequency eddy current that raises the temperature of the material rapidly, thus achieving effective heat treatment.
Applications of High Frequency Induction Heating
The application range for high-frequency induction heating machines is broad, covering high-frequency wave induction, heat treatment, and advanced wave induction for metal melting. Specific industrial applications include:
Brazing and Soldering: It is used to join two metal parts by melting solder material between them.
Heat Treatment: This process can harden, soften, or temper metals to enhance their mechanical properties.
Melting and Casting: High-frequency induction furnaces can melt and cast metals like steel, copper, and aluminum.
Welding: HF induction welding is a non-contact method that heats two metal parts until they fuse together.
Annealing: This process heats a metal to a specific temperature and cools it slowly, making it more ductile.
Surface Hardening: This technology selectively hardens the surface of a metal object, improving wear resistance.
Shrink Fitting: It uses induction heating to expand a metal piece which is then allowed to cool and contract, ensuring a tight fit with another component.
