A method for heating a blank or a preformed steel sheet component for hot forming and/or quench hardening purposes. In at least some regions, the heating is carried out to a temperature above AC3; the heating of the Hank is embodied as a rapid heating and to this end, the blank is heated in a first zone at an average heating rate of >25 K/s up to about 600° C. and above this temperature, is heated at an average heating rate of >10 K/s up to a maximum of the AC3 temperature and then is transferred to a second zone in which the blank that has been preheated in the first zone is heated in at least some regions to temperatures greater than AC3, in particular >850° C., with the heating rate in the second zone being >10 K/s. The invention also relates to a device for carrying out the method.
