Abstract

Through the development of furnace technologies and tool concepts, partial press hardening has become an established process in the automotive industry for setting tailored properties on press-hardened components. Tailored properties on press-hardened components offer the potential to improve crash performance as well as to facilitate downstream joining processes and mechanical treatments. One approach to adjust these properties through local pre-cooling is based on a special oven chamber with an integrated masking technology, called TemperBox®. The integrated mask protects the blank locally from incident heat radiation and simultaneously absorbs the blank's own radiation. An important parameter during this process is the pre-cooling time in the TemperBox®. The pre-cooling time can influence the phase transformation and the component properties. Therefore, blanks made of the conventional press hardening steel 22MnB5 AS150 are partially precooled in the TemperBox® for different periods of time and the component properties are investigated on the basis of formed hat profiles. In addition, a simulation approach for calculating the heat radiation exchange with the finite element software LS-Dyna® is shown. Based on the simulative and experimental investigations, it is demonstrated that there is a dependency between pre-cooling time and the components properties.
