Induction Heating Wires For Hot Heading With IGBT Induction Heating Units
Objective To heat multiple steel wires to 1350ยบF (732ยบC) for hot headingย application
Material Steel wire 0.185โ (4.4mm) OD
Temperature 1350 ยบF (732ยบC)
Frequency 141 kHz
Equipment โข DW-UHF-6ย kW induction heating system, equipped with aย remote workhead containing one 0.66ฮผF capacitor
โข An induction heating coil designed and developedย specifically for this application.
Process A two turn channel coil is used to heat 12 wires at a time toย reach the required 130 parts per minute. The wires are placedย 0.5โ (12.7mm) on center. The top 0.3โ (7.6mm) of the wires are
heated for 5 seconds to achieve the desired temperature.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Elimination of springback effect
โข Extended die life
โข Better grain flow and microstructure
โข Even distribution of heating
