Induction Tempering Spring

Induction Tempering Spring with High Frequency Induction Heating Equipment Objective Temper a spring by heating it to 300°C (570°F) in 2 – 4 seconds Material Stainless steel AISI 302 springs- different length from 60 to 110 mm - outer diameters 8 mm.- wire diameter from 0.3 to 0.6 mm Temperature 300°C (570°F) Frequency 326 kHz Equipment • DW-UHF-10kW induction heating system • remote workhead, two 0.33μF capacitors (total 0.66μF) • multi-turn C-channel coil developed for this application Process Springs are mounted on non-metallic mandrels to facilitate loading and unloading and are placed inside the coil (picture). Power is applied for 2 – 4 seconds, completing the tempering process. The C-channel distributes the heating evenly and enables the convenient staging and removal of the springs. Results/Benefits Efficiency: Energy is applied directly to the springs only;surrounding air and fixturing are not heated. Precision: temperature and duration of process are controlled Convenience: method integrates into a continuous process
