METHOD FOR HEATING A SHAPED COMPONENT FOR A SUBSEQUENT PRESS HARDENING OPERATION AND CONTINUOUS FURNACE FOR REGIONALLY HEATING A SHAPED COMPONENT PREHEATED TO A PREDETERMINED TEMPERATURE TO A HIGHER TEMPERATURE

摘要

There is described a method for heating a shaped component (2) for a subsequent press hardening operation, wherein the shaped component (2) is initially heated to a predetermined temperature and subsequently heated regionally to a higher temperature by means of heating elements (7) of a heating element array (10), said heating elements being controllable independently of one another. In order to ensure an advantageous temperature profile, it is proposed that, while it is conveyed through the heating element array (10), the shaped component (2) is heated with the aid of the heating elements (7) which are arranged in longitudinal and transverse rows (8 and 9) with respect to the conveying direction (3) and are controllable at least in groups with different heat outputs.
