Note: Research: Heating effects on stainless steel & Tantalum discs

Objective:

Heating stainless steel disc & tantalum disc to 1400 °F (760 °C) 

End Product:

radioactivity counting plate 

Equipment:

Ambrell 1.0 kW induction heating system, equipped with a remote workhead containing one 0.66 μF capacitor
An induction heating coil designed and developed specifically for this application

Materials:

Stainless steel and tantalum discs approx 1/2 in (12.7 mm) diameter. End product is radioactivity counting plate 

Temperature:

1400 °F (760 °C)

Frequency:

350 kHz

Testing:

A three-turn helical coil is used to heat the discs to 1400 °F (760 °C). The stainless steel disc reaches temperature in 3.5 seconds, the tantalum disc reaches temperature in 1.7 seconds. The heat up time can also be varied by changing the distance between the coil and the part to suit the application fixturing design

Benefits:

  • Hands-free heating that involves no operator skill for manufacturing

  • Precise even heat without out the use of flame or oven
