Recently, one of our sales leads asked us to validate an induction hardening case by comparing the results of simulation versus real life, so their procurement team can make fact-based decisions. We decided to write an article based on this case to demonstrate the correlation between induction simulation and actual results.
The process - induction hardening of a shaft
The actual workpiece in the manufacturing line (a small splined shaft from gearbox) is rotated 400 revolutions per minute, it's heated up very quickly via induction and hardened in varying depth.
We simulated the same heating process on CENOS simulation software. Our results revealed a higher temperature than projected - around 1200 ℃ which is completely acceptable. With rotation cases, the most important role is played by parameters like simulation time step and material properties.
Frequency - 260 kHz
Heating time 0.5 s
Rotation speed 400 rpm
Current 4242 A
Workpiece material AISI 1045 (medium carbon steel)
Our client wanted to compare the hardening depth of two cases - one from simulation and one from the factory. Images show that the range of depth is between 0.3-2.0 mm, just as they were expecting.
Simulation results were exactly the same as real-life induction hardening outcome, our sales lead was happy to learn that simulation can replace multiple physical prototyping iterations in the lab, thus saving time and digitally transforming the company, which will play competitive advantage during the times of pandemic and social distancing.
