Note: Annealing a steel shaft for stress relief
Objective:
Heating a steel rod to 1200 °F (649 °C) for an annealing, stress relief application
End Product:
Steel shaft
Equipment:
- Ambrell 45 kW induction heating system, equipped with a remote workhead containing eight 1.0 μF capacitors for a total of 8.0 μF
- An induction heating coil designed and developed specifically for this application.
Materials:
- 1.062 in (26.97mm) dia type T-410 stainless steel bar 6 in (1.82m) long
- 1.25 in (31.75mm) dia T-416 stainless steel bar 6 in (1.82m) long
Temperature:
1200 °F (649 °C)
Frequency:
126 kHz
Testing:
A two position 8 turn helical parallel coil is used to heat the stainless steel rod for 30 seconds to reach the requested 1200 °F (649 °C).
Benefits:
Induction heating benefits:
-
Process currently done in batch furnaces, induction heating allows process to be done in-line saving time and energy.
-
No rotation of part needed
-
Flameless process
