Induction Heater Working Pdf

February 18, 2018

Plastics and other non conductive materials can often be heated indirectly by first heating a conductive metal susceptor which transfers heat to the non conductive material. Induction heat treating coils are available in many shapes and sizes and must perform a vari ety of tasks in a given induction heat treating application.

One solution to avoid these problems is use of induction heating.

Induction heater working pdf. Generally for any heating process a flame or an element is applied on the object to be heated. The typical output power of a unit is from 2 to 500 kw. Induction heating devices heater safety regulations the following safety regulations must be observed when working with the heating device.

Induction heater working principle. Induction heating is the process of heating an electrically conducting object usually a metal by electromagnetic induction where eddy currents also called foucault currents are generated within the metal and resistance leads to joule heating of the metal. Induction heating working principles.

Structure and hystory of inductive heating generators an induction heater typically consist of three elements. When the induction coil is placed next to or around a workpiece the lines of force concentrate in the air gap between the coil and the workpiece. Power unit invertergenerator this part of the system is used to take the mains frequency and increase it to anywhere between 20 900 khz.

An induction heating system consists of an induction power supply for converting line power to an alternating current and delivering it to a workhead and a work coil for generating an electromagnetic field within the coil. During this process electrons inside iron are unable to move as fast as the frequency and this gives rise to a reverse current in the metal termed as eddy current. Depending on the application the induction coil design requirements include.

An induction heater is a device that uses a high frequency magnetic field to heat up an iron load or any ferromagnetic metal through eddy current. This causes contamination of the object and the heating process is not very precise or controlled. Before knowing this secret it would be important to know the basic working concept of an induction heater.

Induction heating is an accurate fast repeatable efficient non contact technique for heating metals or any other electrically conductive materials. You might have come across many diy induction heater circuits online but nobody seem to have addressed the crucial secret behind implementing a perfect and a successful induction heater design. Transport the heating device must not be moved directly after heating.

Basic induction heater concept. Further guidance on hazards and specific guidelines for action can be found for example in the section operation page 48. The characteristics of the part metal or plastic.

Meet heat treatment specications in desired production rates be robust enough to tolerate manufacturing variations. Theory of heating by induction 7 tromagnetic or flux around it. First induction heating works directly only with conductive materials normally metals.

The induction coil actually functions as a trans former primary with the workpiece to be heated becoming the transformer secondary.
