Estimating the term…
Disclosed are methods and apparatus for impressing a temperature profile onto a sheet steel component, wherein in one or more first areas, a temperature below the AC3 temperature can be impressed on the sheet steel component, and in one or more second areas, a temperature above the AC3 temperature can be impressed on the sheet steel component, and is characterized in that the sheet steel component is firstly preheated in a production furnace, and is then transferred into the thermal re-treatment station, wherein a radiation heat source is moved over the component in the thermal re-treatment station, by means of which the one or more first areas of the sheet steel component can be kept at a temperature below the AC3 temperature or cooled down further, and the one or more second areas can be heated to or kept at a temperature above the AC3 temperature.
A method for impressing a temperature profile onto a sheet steel component wherein in one or more first areas, a temperature below the AC3 temperature can be impressed on the sheet steel component, and in one or more second areas, a temperature above the AC3 temperature can be impressed on the sheet steel component, characterized in that the sheet steel component is firstly preheated in a production furnace, the sheet steel component is then transferred into a thermal re-treatment station, wherein a radiation heat source is moved over the component in the thermal re-treatment station, by means of which the one or more first areas of the sheet steel component can optionally be kept at a temperature below the AC3 temperature or cooled down further, and the one or more second areas of the sheet steel component can optionally be heated to or kept at a temperature above the AC3 temperature.
Heat treatment apparatus, consisting of a production furnace for preheating a sheet steel component and a thermal re-treatment station for the impressing of a temperature profile onto the sheet steel component, characterized in that the re-treatment station consists of a radiation heat source, wherein the radiation heat source consists of a field with surface emitters, from which the radiation is emitted in the infrared spectrum.
