————————————————————————————————————————————————— Numerical computer modeling is a major factor in the successful design of induction heating systems. Induction heating is a complex combination of electromagnetics, heat transfer, and metallurgical phenomena involving many factors. Heat transfer and electromagnetics are nonlinear and closely interrelated because the physical properties of heated metals depend strongly on both temperature and magnetic [...]
Article discusses unique technology that allows the replacement of carburizing with induction contour hardening for a wide range of complex-shaped components, including parts previously thought to be impossible to induction harden. This includes but not limited to spiral bevel pinions, spiral bevel ring gears, journal and differential crosses, helical bull gears, shaft helical shafts, etc. [...]
————————————————————————————————————————————————————- Induction heating the internal surfaces of a workpiece can be used in applications such as hardening, tempering, annealing, shrink fitting, stress relieving, coating, drying, and brazing. Application specifics requires the use of a variety of different inductor styles to heat internal surfaces including solenoid-type, cylindrical single- and multi-turn coils, hairpin inductors, C-core inductors, and others.

___________________________________________________________________________________________________ When induction surface hardening a shaft, achieving a case depth with a minimum required hardness in the shaft fillet without exceeding the maximum case depth in regions next to the fillet can present challenges, which are related to following phenomena: From an electromagnetic perspective, it is difficult to induce sufficient power density (heat source) [...]
There are three ways to quench gears in spin hardening applications (Ref. 1): • Submerge the gear in a quench tank. This technique is particularly applicable for large gears. • Quench “in place” using an integrated spray quench. Small- and medium-size gears are usually quenched using this technique. • Use a separate, concentric spray-quench block [...]
Whenever someone is talking about induction heating, reference is often made to the phenomenon of skin effect. In most publications devoted to induction heating distributions of current density and power density (heat source distributions) along the workpiece thickness/radius are simplified, and described as exponentially decreasing from the surface into the workpiece. However, in some applications, [...]
There are four popular heating concepts used for the induction spin hardening of gears that employ encircling-type coils: the conventional single-frequency (CSFC), pulsing single-frequency (PSFC), pulsing dual-frequency (PDFC) and simultaneous dual-frequency (SDFC) concepts. All four modes can apply either a single-shot or scanning approach. Click here for more information.
