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   https://dw-inductionheater.com/induction-annealing-stainless-steel-tubes.html?feed_id=249269&_unique_id=6666289135602

Induction Annealing Copper Tubes

Objective

Uniformly high frequency annealing copper tubes simultaneously to 800°F (426°C) in under 10 seconds with induction heating.

Equipment
DW-HF-45kw induction heater

Helical coil

Material
• Two copper tubes

– OD: 0.69’’ (1.75 cm)

– ID: 0.55’’ (1.40 cm)

– Length: 5.50’’ (14.0 cm).

Key Parameters
Power: 27kW

Temperature: 842°F (450°C)

Time: 5 sec

Process:

1. The two copper tubes were placed together in the coil.


2. Induction heating was applied for 5s.

Results/Benefits:

• Improved process control for uniform induction heating to a desired temperature


• Power on demand and rapid, consistent heat cycles


• Technology without pollution, which is both clean and safe
