Induction Heating Non-Magnetic Steel Tubing

A client in the energy storage technology market turned to Ambrell because they needed to heat non-magnetic steel tubing. Given their requirements, THE LAB at Ambrell determined that an Ambrell EASYHEAT^TM 4.2 kW, 150-400 kHz induction heating power supply with a custom-designed single position multiple-turn helical coil was the right solution for their application.

Initial tests were conducted to optimize the power delivered to the part. An infrared camera was used to observe the mesh temperature inside the tube. It was observed that the tube reached temperature within a minute. The mesh inside reached approximately 1022 °F (550 °C) within 5 minutes and remained at that temperature to 10 minutes, at which point the experiment concluded. A good heating pattern was achieved and the results met the client's objectives. 

THE LAB successfully confirmed the viability of this application. Induction's speed of heating was a key factor as was the solid, repeatable results that it delivered. Finally, THE LAB's expertise was also critical. To learn more about complimentary induction heating testing from THE LAB at Ambrell, visit our website.
