Note: Surface hardening of steel screws
Objective:
Rapid surface hardening of steel screws
End Product:
Steel screws
Equipment:
Ambrell 10 kW induction heating system, equipped with a remote workhead containing two 0.3Ä μF capacitors for a total of 0.17Ä μF An induction heating coil designed and developed specifically for this application.
Materials:
Steel screws .25 in (6.3mm) diameter
Temperature:
932 °F (500 °C)
Frequency:
344 kHz
Testing:
A three-turn channel coil is used to heat 9 screws at a time. Power is applied for 3 seconds to reach 932 °F (500 °C) and achieve the required hardness. The screws travel through the coil head down in an automated system at a rate of 200 screws per minute
Benefits:
-
Precise application of heat
-
Faster process time and production rates
-
Ability to incorporate into existing production lines
-
Repeatable, consistent results
