Induction heating is a technology that uses electromagnetic fields to generate heat directly within a conductive material. This process is based on the principle of electromagnetic induction, discovered by Michael Faraday, which states that a time-varying magnetic field induces an electric current within a conductor. This current, known as induced current or eddy current, generates heat through the Joule effect, rapidly and uniformly heating the material.
How Does Induction Heating Work?
The induction heating system uses a coil, called an inductor, through which alternating current flows. The inductor creates a varying magnetic field that interacts with the material to be heated, usually a conductive metal like steel or copper. When the material enters the magnetic field, induced currents are generated within it, leading to quick and controlled heating.
This method offers several advantages over other heating technologies, such as:
- Energy efficiency: Heat is generated directly within the material, reducing energy losses.
- Precision: Temperature and heating time can be precisely controlled, ensuring uniformity and repeatability of the process.
- Speed: Induction heating is much faster than traditional methods, as it acts directly on the material without the need to transfer heat from another source.
Induction Heating in the Extrusion Process: Bausano's Solution
