————————————————————————————————————————————————— 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 [...]
The majority of commercial codes used for computer modeling of induction heating processes are all-purpose programs originally developed for modeling processes occurring in electrical machines, motors, circuit breakers, transformers, and magnetic recording systems, and later adapted to induction heating needs. Despite the capabilities of modern commercial software, many generalized programs have difficulty taking into consideration [...]
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.

Certain numerical computational methods or software are preferred for each family of induction heating applications. There is not a single universal computational method that optimally fits all types of applications. In recent years, the finite element method (FEA) became the dominant numerical simulation tool for a variety of engineering applications. Though FEA is a very [...]
Many bars, billets, and rods lend themselves to processes in which the entire workpiece is heated and fed into a roll former or other type of forming machine. In some cases, only a certain part of the workpiece (the end, for example) needs to be hot formed. One such application is a sucker rod used [...]
