Abstract
The invention relates to a furnace system and a method for the controlled heat treatment of sheet metal components in individual component zones. The invention proposes a furnace system that is suitable for partly heating components made of steel sheet to a temperature above the AC3 temperature. The furnace system has a production furnace for heating the steel sheet parts to a temperature that is close to but below the AC3 temperature, said furnace system further having a profiling furnace with at least one level. The at least one level has an upper and a lower part and a product-specific intermediate flange that is introduced into a corresponding receiving area. The product-specific intermediate flange is designed to impose a specified temperature profile on the component with temperatures over AC3 for regions to be hardened and below AC3 for softer regions. Furthermore, the invention relates to a corresponding method for partly heating steel sheet parts to a temperature above the AC3 temperature.
