Abstract

The effects of magnetizer parameters on the temperature field of high-strength steel blanks are investigated through the combination of experiment and simulation. An electromagnetic-temperature three-dimensional finite element model is simulated. Numerical simulation indicates the spacing in the width direction significantly affects the temperature field of steel blanks, and the optimal spacing of magnetic ring group to generate a rectangular low-temperature zone is 10 mm. The customizability of district-controlled induction heating process is verified, and then, the differentiated temperature field of automobile B-pillar is tailored. The temperature field simulation results are validated through heating experiments. Hot stamping experiment shows that a reduced U-shape B-pillar with tailored properties is generated after district-controlled induction heating-hot stamping. The temperature fields of B-pillar with two dimensions indicate this new process satisfies the demand of automobile components with tailored properties, and the parameters of magnetizers play the most important role in the new process.
