Principle of high-frequency induction heating

basic information

This is an introduction to the principle of high-frequency induction heating. ■ Unlike other heating methods that rely on the transfer of heat from external heat sources through convection, radiation, or conduction, induction heating generates heat within the object being heated itself. ■ Rapid and versatile heating is possible. - High heating efficiency allows for an increase in power density, making rapid heating easy. - By appropriately selecting the frequency, output, and shape of the induction coil according to the purpose, it can accommodate various heating conditions such as localized heating, uniform heating, and surface heating. ■ Essentially, it does not require the furnace body or atmosphere to be heated; the object being heated itself increases in temperature. - There is no need to heat unnecessary materials, ensuring competitive energy costs. - The heating response is good, making control easy. - Since the heat is generated by the object itself, the temperature responds quickly to the application of high-frequency power. - A dielectric coil is required to apply magnetic flux to the conductor. ■ For those who want to know more about the principles, please download the materials. ■ If you are considering "existing replacements," please provide the manufacturer of the product you are using.
