Induction Heating: Eliminate Cracking at Holes pt. 1

There are two factors that can cause the overheating: • An increase of power density (heat source) due to the redistribution of eddy current flow. • The lack of adjacent […]

Induction Power Supplies pt. 1

Transistorized induction heating power supplies offer many advantages over equipment which uses older technologies. These power supplies are much smaller and can often be mounted close to the heating coil. […]

Single Coil Dual Frequency: Gear Hardening pt. 3

As a rule, when it is necessary to harden only the tooth tips, a higher frequency and high power density should be applied; to harden the tooth roots, use a […]

Assessment of Magnetic Flux Concentrators

Magnetic flux concentrators (also called flux intensifiers, diverters, or controllers) are made from high-permeability, low-power-loss materials. They are routinely used in induction heat treatment applications in a manner similiar to […]

Coil failure: pt 11c : Frequency Selection

The temperature at which a ferromagnetic body becomes nonmagnetic is called the Curie temperature (Curie point).Depending upon the heat intensity (Cº/s or Fº/s) there can be some shifting of the […]

Coil Failure pt 13: Proximity Effect

When the currents flow in opposite directions, a strong magnetic field forms in the area between the bus bars. This occurs because in this area the magnetic field lines produced […]

Joining Components by induction: pt. 2

Compared with brazing and soldering, adhesive bonding is much more versatile because the components to be joined don not have to be metals. Plastics, ceramics, glasses and other nonmetallic materials […]
