Induction hardening steel screw threads

Induction hardening steel screw threads

Objective Heat steel roofing screw to 1650 ºF to harden the threads Material : Steel roofing screws of varying diameters less than 1.25” (31.75mm) diameter, 5” (127mm) long Temperature: 1650 ºF (899 ºC) Frequency: 291 kHz Equipment • DW-UHF-6kW-I handheld induction heating system, equipped with a remote workhead containing two 0.33µF capacitors for a total of 0.66µF portable induction heating units • An induction heating coil designed and developed specifically for this application. Induction Hardening Process A five turn helical coil is used heat the screw threads. The screw is placed in the coil, heat is applied for 8 seconds to achieve a 2” long zone at the required hardness. Results/Benefits Induction heating provides: • Very rapid heating, faster production rates, efficient • Ability to incorporate into existing production lines • Repeatable, consistent results • Even distribution of heating
