Induction Annealing Steel Parts Shortens Production Time [VIDEO]

Featured Image


Induction annealing a steel tool.


In this application video from THE LAB at Ambrell, a steel tool is heated to 1400 °F (760 °C) for an annealing application. An Ambrell EKOHEAT® induction heating power supply is used. The red sight on the part is from a pyrometer, the temperature displays on the controller to the left, and there is temperature indicating paint down the part.




As you saw in the video, heating with induction took approximately 40 seconds. The client was using an oven for this application, but wanted a more rapid heating method for their annealing application. Induction also takes up less floor space than an oven, has no ramp up time, and heats only the portion of the part that requires heating. 


Here is the full video transcription:

Today's application video involves annealing a steel tool using an Ambrell EKOHEAT induction heating power supply and a three-turn channel coil. The part will be heated to 1400 °F (760 °C) and the red sight on the part is an optical pyrometer. There is temperature indicating paint down the part. 


Alright, the power is now on and heating will take approximately 40 seconds. This client was using an oven but is looking to reduce their heating time with induction heating. As you can see, the temperature is approaching the target. We've now hit our target temperature, the power is now off, and as you can see the heating was very uniform.
