Abstract

A hot forming line for producing hot formed and press hardened steel sheet products, includes: a forming device; a heating device having a temperature treatment station, wherein the temperature treatment station includes an upper tool and a lower tool, and at least one temperature treatment source; and exchangeable temperature treatment plates for conductive temperature treatment of a blank or part inserted into the temperature treatment station, wherein the exchangeable temperature treatment plates are constructed for arrangement on the upper tool and/or the lower tool, and the temperature treatment source is constructed for heating or cooling the temperature treatment plates. The temperature treatment station is constructed for treating different regions of the blank or part with different temperatures by conductive contact of the temperature treatment plates with the blank of part.
