Abstract (en)
[origin: EP1847342A1] Production of a protective gas atmosphere in a production plant for hot deforming metals comprises injecting the protective gas completely or partially into a continuous furnace (1) via a pressing chamber (3) and/or via a transport channel (2). A press with the pressing chamber is connected to the furnace via the transport channel so that a closed protective gas atmosphere is produced from the furnace inlet up to the pressing chamber and the metal is guided from the atmosphere only after deforming and cooling. An independent claim is also included for a device for producing a protective gas atmosphere in a production plant for hot deforming metals.
