Abstract (en)
[origin: EP1215291A1] Process for cooling and treating heated rotationally symmetrical bodies made from steel or steel alloys comprises initially descaling the bodies; and adjusting the mechanical properties using complex cooling processes which are carried out for different volumes and/or surface regions of the body to be treated so that these regions can be controlled or regulated online by spraying or blowing with a medium. An Independent claim is also included for a device for cooling and treating heated rotationally symmetrical bodies made from steel or steel alloys. Preferably the rotationally symmetrical hot bodies are rotated about their axes of rotational symmetry during descaling and during subsequent volume and surface specific cooling. The cooling medium is simultaneously sprayed or blown onto the surface regions to be treated.
