Note: Hardening steel screw threads
Objective:
Heat steel roofing screw to 1650 ºF to harden the threads
End Product:
Steel roofing screw
Equipment:
Ambrell 2 kW induction heating system, equipped with a remote workhead containing two 0.33µF capacitors for a total of 0.66µF An induction heating coil designed and developed specifically for this application.
Materials:
Steel roofing screws of varying diameters less than 1.25” (31.75mm) diameter, 5” (127mm) long
Temperature:
1650 ºF (899 ºC)
Frequency:
291 kHz
Testing:
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.
Benefits:
-
Very rapid heating, faster production rates, efficient
-
Ability to incorporate into existing production lines
-
Repeatable, consistent results
-
Even distribution of heating
