Title (EN) ROLL FOR A ROLLING-MILL
(FR) CYLINDRE DE LAMINOIR
Abstract:
(EN) The present invention relates to a roll (26) for rolling a long semifinished article (18). The roll is rotatable about an axis of rotation (r) and comprises: a groove (44) able to reproduce a nominal arc (h) of the outer profile of the semifinished article; and a groove plane (π) which intersects, perpendicularly with respect to the axis of rotation, the roll along its smaller section. The roll is asymmetrical with respect to the groove plane (π). The invention also relates to a rolling station (22) and a continuous rolling mill (20) which comprise a plurality of such rolls. Finally, the invention relates to a method for reconditioning these rolls.
(FR) L'invention concerne un cylindre (26) pour laminer un article long semi-fini (18). Le cylindre tourne sur un axe de rotation (r) et comprend : une gorge (44) capable de reproduire un arc nominal (h) du profil extérieur de l'article semi-fini ; et un plan de gorge (π) qui coupe, perpendiculairement à l'axe de rotation, le cylindre sur la longueur de sa partie la plus petite. Le cylindre est asymétrique par rapport au plan de gorge (π). L'invention concerne également un poste de laminage (22) et un laminoir continu (20) qui comprend une pluralité desdits cylindres. L'invention concerne enfin le reconditionnement de ces cylindres.
