Abstract
A method for manufacturing a steel component from a blank is provided. Firstly, a blank is placed in a conveyor system. Then, at least a preselected zone of the blank is preheated while the blank is retained at a predetermined preheating location. Finally, the blank is conveyed through a furnace. A preheating system for heating blanks in a production line is also provided.

-15. (canceled)
A method for manufacturing a steel component from a blank, the method comprising:
- placing a blank on a conveyor system, the blank comprising a first zone made from a first material and a second zone made from a second material, different than the first material;
- followed by
- preheating the blank by performing a preheating process comprising (1) directing heat at the first zone and not the second zone;
- or (2) applying heat to both the first and second zones such that the second zone is heated to a temperature different than a temperature of the first zone;
- and after completion of the preheating,
- conveying the preheated blank through a furnace having a furnace temperature at or above an Ac3 temperature of the first zone or the second zone of the blank for heating the blank to a temperature equal to or above the Ac3 temperature of the first zone or the second zone, and wherein the preheating comprises retaining the blank at a predetermined preheating location upstream of the furnace.

A method for manufacturing a steel component from a blank, the method comprising:
- placing a blank on a conveyor system, the blank comprising multiple zones, at least two of which have a different thickness or are made from a different material;
- preheating the blank by a preheating system by performing a preheating process comprising (1) directing heat to at least one of the zones and not to at least one other zone;
- or (2) heating at least two zones to different temperatures, the temperatures being below an Ac3 temperature of the at least two zones of the blank;
- and
- conveying the preheated blank through a furnace, positioned downstream from the preheating system and having a furnace temperature at or above the Ac3 temperature of the at least two zones of the blank for heating the blank to a temperature equal to or above the Ac3 temperature of the at least two zones.
