Abstract

In a method for producing in particular structural components or chassis components for a motor vehicle by hot or semi-hot forming, a sheet metal blank is heated in a heating station at least in a first region from a starting temperature to a target temperature, and then the warm blank is transferred to a cooled pressing tool and is formed and press-hardened. The heating station includes at least one burner zone which includes at least one burner, in which zone the sheet metal blank is heated from the starting temperature to the target temperature, and at least one burner is operated with a combustion gas and an oxygen-containing gas and the sheet metal blank comes into direct contact with the burner flame.
