Note: Preheating a magnetic steel die
Objective:
To preheat a magnetic steel die; the end product is tubing and fittings
End Product:
Tubing and fittings
Equipment:
Ambrell EKOHEAT 15 kW, 50-150 kHz induction heating power supply with a remote workhead. A single position, three turn helical coil designed and developed for this application
Materials:
Steel die
Temperature:
250 °F (121 °C)
Frequency:
115 kHz
Testing:
The die was placed under the induction coil, approximately 3.5 in (89 mm) away from it to simulate production conditions. With an EKOHEAT 15 kW power supply under simulated production conditions, the die can heat to temperature within ten minutes. A key benefit over the client in s resistance heater is there will no longer be a need to open the chamber to remove the heater.
Benefits:
-
Speed: The client in s resistance heater took more than ten minutes to heat the die to temperature
-
Footprint: Induction requires a minimal footprint, saving valuable floor space
-
Setup: An induction coil (ceramic) can remain in the client in s chamber and expedite the process.
