Skin effect, frequency and heating

2012/10/9Skin effect means that the highest the frequency is, the thinest the skin depth is (or the depth is simply smaller because of the material). That means the section of the workpiece with electric current in it is smaller, and according to R=ρ*L/S (ρ - electrical resistivity, L - length, S - section area) the resistance is higher, thus heating more.

Induction heating

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents.An induction heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet.

Continuous Induction Heating of Aluminum Billets

Induction is a proven, reliable and efficient method of heating aluminum alloys. However, aluminum alloys have material properties that, if unaccounted for, can result in unexpected challenges. Understanding the unique facets of the induction heating of aluminum can

Induction heating: Types, Advantages, Application

Induction heating: Induction heating processes make use of currents induced by electromagnetic action in the material to be heated. Induction heating is based on the principle of transformers. There is a primary winding through which an a.c current is passed. The

Frequency Selection for Induction Heat

2005/5/10All of the factors mentioned above may influence frequency selection for surface hardening, the most important and complicated induction heating process. It is difficult to give general recommendations for frequency selection due to the large variety of part geometries and heat treating specifications, and, therefore, different groups of parts must be considered separately.

Designing an induction coil for your application Start with understanding where the heat needs to be generated in the part to perform the process, and then design the coil to achieve the heating effect. Similarly, frequency selection will depend on the induction heating

Inductive Coupling and how to Minimize their Effects in

However, at high frequency common-mode the cable has little efficiency. The use of shielding in inductive coupling Magnetic shielding can be applied in noise sources or in signal circuits to minimize the coupling effect. To shield low-frequency magnetic fields

100 Most Important MCQ Of Heating and Welding with

In induction hardening, rapid heating is generated by electromagnetic induction when a high-frequency current is passed through a coil surrounding the part. The depth to which the heated zone extends depends on the frequency of the current and the duration of the heating cycle.

How Induction Heating Works

In 1887, Sebastian Z. de Ferranti proposed induction heating for metal melting and filed the first patent on the industrial applications of induction heating. The first fully-functional induction furnace was presented in 1891 by F. A. Kjellin, and the first high-frequency furnace application of induction heating was implemented by Edwin F. Northrup in 1916.
