Abstract

A hot-forming apparatus may be used to produce a press-hardened shaped component from a blank. The hot-forming apparatus may include a furnace for heating the blank and a pressing device for forming and cooling the blank heated in the furnace. The hot-forming apparatus also includes, upstream of the furnace, a preheating roll truing device with a temperature-controllable roller for straightening and preheating the blank. A corresponding method may be used to produce the press-hardened shaped component from the blank.
