Note: Annealing Lock Nuts

Objective:

To heat locknuts to 2150 °F (1176 °C) for annealing 

End Product:

Locknuts

Equipment:

  • Ambrell 3.0 kW induction heating system, equipped with a remote workhead containing one 0.66 μF capacitor.
  • An induction heating coil designed and developed specifically for this application. 

Materials:

Waspaloy locknut 

Temperature:

2150 °F (1176 °C)

Frequency:

362 kHz

Testing:

A three turn helical coil is used to heat the locknut to 2150 °F for 5 seconds.

Benefits:

Induction heating provides:

  • Produces repeatable, rapid and accurate heating cycles making it ideal for in-line production processes
  • Can heat very small areas within precise production tolerances
  • Even distribution of heating
