Note: Heat steel flat stock pry bar for forging

Objective:

Customer wishes to replace gas-fired slot furnaces with induction heating units in their forge shop to heat both ends of flat stock simultaneously

End Product:

pry bar

Equipment:

Ambrell EKOHEAT 100 kW induction heating system, equipped with a remote heat station containing eight 6.3 μF capacitors for a total of 12.6 μF

Materials:

Customer-supplied steel bars

Temperature:

220 °F (1200 °C)

Frequency:

31 kHz

Testing:

A specially-designed multi-turn helical coil was used to provide the heat to the steel parts. Initial tests were conducted to optimize the power delivered to the part and to understand the heating patterns achieved. After several changes and iterations on the coil setup the following data is collected from the testing.

Benefits:

  • Speed: Induction's rapid heating allowed the client to reduce their cycle time and increase throughput.

  • Consistency/Repeatability: The client can expect the same result time after time with induction.

  • Efficiency: Induction is an energy efficient medium of heating, so it enabled the client to not only save time, but money too.
