Note: Heating threaded area of fastener
Objective:
To heat the threaded area of fasteners to 375ºF (190.5ºC) at a rate of 8000 parts per hour
End Product:
Non magnetic threaded pins
Equipment:
- Ambrell 20 kW induction heating system, equipped with a remote workhead containing four 1.0µF capacitors for a total of 1.0 µF
- An induction heating coil designed and developed specifically for this application.
Materials:
Non magnetic threaded pins in a 0.03” (.76mm) thick steel plate, pins are 0.5 “ (12.7mm) apart center to center
Temperature:
375 ºF (190.5ºC)
Frequency:
235 kHz
Testing:
A single-turn channel coil is used for this application. The threaded pins are placed in a stainless steel plate 0.5” (12.7mm) apart center to center. Twenty pins are heated for 10 seconds to reach 375 ºF (190.5ºC) at a rate of 8000 parts per hour.
Benefits:
-
Localized only to the threaded area
-
Increased production time
-
Flameless process
-
Even distribution of heating
