Note: Heating a steel pipe to transport melted magnesium

Objective:

To heat a steel pipe to 1100 °F (593 °C) to transport melted magnesium 

End Product:

Melted magnesium

Equipment:

Ambrell 125 kW induction heating system, equipped with a remote workhead containing one 25 μF capacitor.
An induction heating coil designed and developed specifically for this application

Materials:

Steel pipe 14.5 in (4.42 m) long with a 3.5 in (88.9 mm) OD 

Temperature:

1100 °F (593 °C)

Frequency:

9 kHz

Testing:

A specially designed double U channel coil the length of the pipe is used in this application. The pipe is placed inside the coil and power is supplied. The voltage is set and the power output is 100 kW. As the part reaches the Currie point the power drops to 80 kW and the voltage must be increased to achieve the 100 kW. The pipe  reaches 1100 °F (593 °C) in 20 minutes. 

Benefits:

  • Controllable and repeatable heat pattern that keeps material in liquid form

  • Environmentally friendly 

  • Even distribution of heating

  • Movable workhead that can be located away from the power supply
