1-10. (canceled)
A method of making a heated steel blank, the method comprising:
- hot-forming the steel blank;
- press-hardening the steel blank;
- and
- heating the steel blank using a plurality of temperature-adjusting stations, each temperature-adjusting station of the plurality of temperature-adjusting stations being arranged one behind the other in a row, wherein heating the steel blank comprises heating the steel blank in stages at each of the plurality of temperature-adjusting stations to at least an austenitization temperature, and the heating is performed at a temperature difference of less than 300° C. at each of the plurality of temperature-adjusting stations.
1 more element
A temperature-adjusting station, the temperature-adjusting station comprising:
- at least one temperature-adjusting plate configured to adjust a temperature of a steel blank at least in certain portions of the steel blank;
- and
- a heating conductor in the temperature-adjusting plate,
- wherein the heating conductor is configured to heat the temperature-adjusting plate and to inductively heat the steel blank.
