WHAT IS INDUCTION HEATING
Whenever the high or medium frequency alternating electric current changes direction, the generated magnetic field change direction in turn.
When an electrically conducting component is inserted into the magnetic field it absorbs the energy as alternating electric current.
As in a transformer, the inducted current in the workpiece (secondary circuit) is proportional to the current circulating in the heating coil (primary circuit) and inverse to the square of their distance.
The inducted electric current, also called parasitic current or eddy current, generates heat on the surface of the component due to the electrical resistance of the material (called Joule effect).
A boil is used to transfer energy into the piece to be heated using an alternating electromagnetic field in its mirror image.
The electric current flows through the coil and generates the electromagnetic field that is capable of producing the electric field that is capable of producing the electric current in the piece.
The coil, most often called heating coil, defines the electromagnetic field and therefore the effectiveness and the efficiency of heating.
The heating coils for induction heating can have very different shapes and complexities: from a simple single-coil or solenoid heating coil ( which consists of a copper tube shaped around a spindle) to precision heating coils machined from semi-finished copper and brazed together.
WHY CHOOSE INDUCTION HEATING?
The many advantages of using an inductor heater, especially in the field of hot forging, gardening, heating coating tubes, casting of precious metals, have led the entire market for years now to prefer this type of technology for the thermal raising of workpieces.
The areas of application of metal induction heating are numerous, multiple and disparate.
