Note: Annealing lip on cryogenic dewar
Objective:
Annealing a 1” lip on aluminum cryogenic dewar that has been work hardened during the process of spin forming.
End Product:
Aluminum dewar
Equipment:
- Ambrell 3.5 kW induction heating system, equipped with a remote workhead containing one 1.0 µF capacitor.
- An induction heating coil designed and developed specifically for this application.
Materials:
Aluminum dewar, lip has a 3.24” (82.3mm) ID and is 0.05” (1.3mm) thick
Temperature:
800 ºF (427 ºC)
Frequency:
303 kHz
Testing:
A two turn helical coil is used to heat the lip on the cryogenic dewar. The dewar is placed in the coil and power is applied for 2 minutes to anneal the required 1” heat zone.
Benefits:
Induction heating provides:
-
Hands-free heating that involves no operator skill for manufacturing
-
Fast, controllable, accurate heating
-
High efficiency, low energy cost
-
Even distribution of heating
