摘要

The method for producing a form-hardened component made of a steel-plate, comprises heating a board (15) tailored on given dimensions in an oven within a given time at a given temperature and then form-hardening in a tool. The board is flexible-hot rolled before the form-hardening of the board in order to obtain an adjustment of different thickness over the length of the board. The thickness adjustment of the board is carried out first by a first roller and subsequently by a second roller with an orientation of the second roller different from the orientation of the first roller. The method for producing a form-hardened component made of a steel-plate, comprises heating a board (15) tailored on given dimensions in an oven within a given time at a given temperature and then form-hardening in a tool. The board is flexible-hot rolled before the form-hardening of the board in order to obtain an adjustment of different thickness over the length of the board. The thickness adjustment of the board is carried out first by means of a first roller and subsequently by means of a second roller with an orientation of the second roller different from the orientation of the first roller. The flexible-hot rolling is carried out at 500-950[deg] C. The board is tempered during the flexible-hot rolling. A monitoring and/or regulating of the thickness of the board is carried out during the flexible-hot rolling. The heating of the board is carried out at the temperature in a continuous furnace. A taylored rolled blank is produced after the flexible hot-rolling and before the form-hardening from the board. Independent claims are included for (1) a form-hardening component such as body of a motor vehicle; and (2) a shaping device for producing a form-hardening component made of a steel-plate.
