Abstract

Method for treatment of rolled profile material comprises straightening rolled profile (1) with plastic forming at 750-1100 degrees C temp.. Initial cooling takes place with locally equal intensity to 5-120 degrees C temp. above the Ar point of the material. This is followed by cooling which has equal intensity in the longitudinal direction of the profile, but varies along the circumference of the profile cross section to ensure a martensitic-free fine pearlitic structure. Final cooling takes place with locally equal intensity down to room temp.. Also claimed is the appts. for carrying out the above heat treating, novel in that is has a preparatory section (A), a second cooling section (B) and a final cooling section (C). <IMAGE>
