Induction Annealing Stainless Steel Tubes

Induction Annealing Stainless Steel Tubes With High Frequency Heating Equipment Objective To anneal a ¼” area around an oval cutout on a stainless steel tube prior to extrusion Material .75” (19mm), 1.5” (38.1mm) and 4” (101.6mm) diameter steel tubes Temperature 1900 ºF ( 1038 ºC) Frequency 300 kHz Equipment • DW-UHF-20kW induction heating system, equipped with a remote workhead containing one 1.0μF capacitor. • An induction heating coil designed and developed specifically for this application. 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 .25 (6.35mm) diameter around the cutout. Results/Benefits Induction heating provides: • 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 Annealing Stainless Steel Tubes
