Induction Heating Stainless Steel Rod For Hot Forming With RF Induction Heating Units
Objective Heating 300 series stainless steel rod to 1800ยบF (982ยบC) forย forming application
Material 1โ (25.4mm) length of 300 series stainless steel rod ยพ โย (19mm) diameter
Temperature 1800 ยบF (982ยบC)
Frequency 52 kHz
Equipment โข DW-HF-25kW induction heating system, equipped with aย remote workhead containing two 1.25ฮผF capacitors for aย total of .625ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A four turn helical coil is used to heat the stainless steel rod toย 1800 ยบF (982ยบC) for 10 seconds. For manufacturing purposes aย refractory shield should be used between the coil and rod to
keep the heat directed on the rod. Refractory shield was notย used during testing.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Improved production rates with minimal defects
โข Low pressure and minimal residual part stress
โข Even distribution of heating
