Abstract

La présente invention se rapporte à un procédé pour améliorer la qualité de produits laminés se présentant sous la forme de profités. Le procédé est caractérisé en ce qu'à la sortie du laminoir à chaud, on soumet ledit profilé se trouvant à une température comprise entre 1000 et 800 degrés C à une trempe superficielle pendant une durée comprise entre deux et six secondes, trempe au cours de laquelle le profilé, dont les épaisseurs sont comprises entre 6 et 40 mm, est soumis à une intensité de refroidissement de l'ordre de 1,5 à 5 MW/m**2, la température d'égalisation du profilé survenant par auto-revenu étant comprise entre 500 et 700 degrés C. Application à toute espèce d'acier, calmé ou semi-calmé ou effervescent.
