Annealing Lock Nuts

Objective

To heat locknuts to 2150ºF (1176ºC) for annealing 

End Product

Locknuts

Equipment

• Ambrell 3.0 kW induction heating system, equipped with a remote workhead containing one 0.66µF capacitor.

• An induction heating coil designed and developed specifically for this application. 

Materials

Waspaloy locknut 

Temperature

2150ºF (1176ºC)

Frequency

362 kHz

Testing

A three turn helical coil is used to heat the locknut to 2150ºF 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
