Title
(DE) KALIBERKONTUR DER WALZE EINES ROHRWALZWERKES
(EN) CALIBRE CONTOUR IN A ROLLING MILL ROLLER FOR TUBES
(FR) CONTOUR DES CANNELURES DES CYLINDRES D'UN LAMINOIR A TUYAUX
Abstract
(DE)
Die Erfindung betrifft eine Kaliberkontur der im wesentlichen kreisförmig kalibrierten Walzen eines Reduzierwalzwerkes mit Dreiwalzengerüsten, insbesondere zum Walzen dickwandiger Rohre mit einem Wanddicken/Durchmesserverhältnis von mehr als 0,25. Dabei weist erfindungsgemäß die Kaliberkontur jeder Walze (1) im Bereich des Kalibergrundes eine Durchmessererweiterung (5) auf, in der der im Walzensprung des in Walzrichtung jeweils vorgeordneten Kalibers gewalzte Materialbereich verformbar ist.
(EN)
The disclosure concerns a calibre contour in the substantially circular rollers of a reduction roller mill with three-high stands, intended in particular for use in rolling thick-walled tubes with wall thickness/diameter ratio which is greater than 0.25. The calibre contour of each roller (1) has a widening in the diameter (5) in the region of the contour floor in which the region of rolled material rolled to an upstream (in the direction of the roll) calibre can be deformed.
(FR)
L'invention concerne un contour des cannelures des cylindres de calibrage sensiblement circulaire d'un laminoir réducteur doté d'une cage trio, notamment pour le laminage de tuyaux à paroi épaisse dont le rapport épaisseur/diamètre est supérieur à 0,25. Selon l'invention, le contour des cannelures de chaque cylindre (1) présente une augmentation de diamètre (5) dans la zone de la base de cannelure, dans laquelle la zone de matériau laminé est déformable dans la pointe de cannelure située en amont dans le sens de laminage.
