Induction Hardening Steel Blades

Objective

A manufacturer needed to quickly and repeatedly harden steel blades. They turned to THE LAB at Ambrell to engineer a solution that would work for their blade hardening application. They were drawn to induction heating because of its speed, repeatability and comparative safety.

Evaluation

A custom-designed single-turn helical coil was built to generate the required heating for this hardening application. Initial tests were conducted to optimize the power delivered to the part using an Ambrell EASYHEAT 6 kW, 150-400 kHz induction heating system. The target temperature for the application is 1600 °F (871 °C). 

Solution

The application reached temperature in less than 15 seconds, meeting the client's objective. In practice, the part would be run through the coil into a quench.

THE LAB at Ambrell has considerable experience with various heating applications, which enabled them to deliver a solution that met the client's requirements. To learn more about free application testing, visit our page about THE LAB to get the process started.
