What is 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 (also called Foucault currents).

An induction heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor called eddy currents.

The eddy currents flowing through the resistance of the material heat it by Joule heating. In ferromagnetic (and ferromagnetic) materials like iron, heat may also be generated by magnetic hysteresis losses.

Why use induction heating?

1.      Induction heating is a GREEN process as it does not emit fumes or CO2 into the environment, emissions are controlled by the electricity generating company at one site and are easy to monitor.

2.      The result of only a small proportion of the material being heated, commonly less than 5% of the mass being heated to accomplish the required properties, then there is less energy consumed, overall, to heat treat the component when compared with conventional furnace heat treatment methods.

3.      Again due to the small areas heated there is a considerable reduced heat treatment distortion so much so that the majority of the components we heat treat are ready to assembly after heat treatment.

4.      Grinding costs can constitute 25~30% of the total cost of a component. Modern CNC lathes can turn components more accurately to size than they can be ground and with a better surface finish. Save money by specifying induction hardening.

5.      Some components require some areas to remain soft after heat treatment. This can only be achieved in a furnace by ‘stopping off’ the component. The ‘stopping off’ technique alone is usually more expensive than the most of the induction hardening process and the induction process only hardens the portions required to be hard.

FAQ

The frequency of current used depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.

What is induction heating?

The heating method known as induction heating occurs when an electrically conductive material is placed in a varying magnetic field. Induction heating is a rapid form of heating in which a current is induced directly into the part being heated. Induction heating is a non-contact form of heating.

Can you braze glass or ceramics with induction?

If you work with glass or ceramics, a compact vacuum furnace is a great solution for brazing. You'll get quick, clean heat with very precise temperature control.

What makes up a typical induction heating system?

A typical induction heating system consists of the induction heating power supply, an induction heating coil, and a water-cooling source, which cools the coil and several internal components inside the power supply. The induction heating power supply sends alternating current through the induction coil, thus generating a magnetic field. When a work piece is placed within the coil and enters the magnetic field, eddy currents are induced within the workpiece, generating precise and localized heat without any physical contact between the induction coil and the work piece.

What is an induction heating coil (inductor)?

The varying magnetic field required for induction heating is developed in the induction heating coil via the flow of AC (alternating current) in the coil. The coil can be made in many shapes and sizes to custom fit a specific application. The coils can range from tiny coils made of copper tubing used for precise heating of extremely small parts in applications such as soldering and ferrule heating to large coil assemblies of copper tubing used in applications such as strip metal heating and pipe heating.

What are some of the other advantages to using Induction Heating?

Fast Cycle Times – With induction heating technology, heat is produced instantly and directly within the part being heated.  Thus heat can be supplied as quickly as a material will permit it, eliminating typical soak times associated with radiation or convection heat technologies. 

Accurate Heat Zones - Through the development of an induction coil combined with the specification of the proper power and frequency, the can isolate or pinpoint a heat-zone, small or large without affecting surrounding areas.  The result is minimal distortion in part being heated, yielding higher quality production. Additional infrared temperature control devices can also be added for further control of a process. 

Consistent and Repeatable - Due to the development of Solid-State power supplies, the heating pattern produced by a given induction coil will be consistent from day to day, month to month.  Since the induction coil is not in any contact with the part being heated and the part is being presented to the coil in a consistent fashion, the process will remain repeatable, unlike traditional flame heating or resistance heating, which have constantly changing characteristics. 

Space Requirements and Efficiency - Due to the smaller space requirements for induction heating over many traditional heating methods, this technology lends itself to bench-top/work cell environments and in-line semi or fully automated processes.  In addition Induction Heating technology is energy efficient, power consumption to create the output power is minimal and in idle or stand-by conditions power consumption is greatly reduced since the power is only on when the system is being utilized for the intended process. 

Environmentally Friendly - Induction heating is an extremely clean heat.  It does not produce harmful emissions or loud noise.  It does not heat the environment or area outside the work coil, since the heat is only generated in the work piece being heated.  Thus induction heating assists in creating more favorable working conditions.
