Anneal an oval cut out on a stainless steel tube prior to extrusion

Anneal an oval cut out on a stainless steel tube prior to extrusion


Objective: To anneal a ¼” area around an oval cutout on a stainless steel tube prior to extrusion.


Frequency: 300 kHz


Equipment:
  • Ambrell 10kW induction heating system, equipped with a remote workhead containing one 1.0μF capacitor;
  • An induction heating coil designed and developed specifically for this application.

Material: .75” (19mm), 1.5” (38.1mm) and 4” (101.6mm) diameter steel tubes


Temperature: 1900 °F (1038 °C)


Process:

A single turn helical coil is used on the 4” (101.6mm) diameter tubes and a two turn helical coil is used on the smaller diameters. The coil is placed over the oval cutout and power is supplied for 15 seconds to anneal a 0.25" (6.35mm) diameter around the cutout.


Benefits:
  • Precise and controllable placement of heat to anneal only the required area
  • Faster process than flame
  • Repeatable results
  • Hands-free heating that involves no operator skill for manufacturing
