The invention relates to a method for the continuous casting of a metal strand (1), in which the cast strand (1) leaves a die (2) vertically or arcuately downwards and is subsequently guided in a strand guide (3), wherein the strand guide (3) has a number of pairs of rollers (4), which define between them an adjustable roller nip (5), and wherein, at the start of casting, to close the die (2) in the downward direction, a piece of strand (6) is introduced into the die (2) and is followed by the cast strand (1). In order to improve the adjustment of the roller nip, the invention provides that the piece of strand (6), which is produced with a defined or calibrated thickness (d), is inserted between the respective pairs of rollers to calibrate and/or measure the roller nip (5).
L'invention concerne un procédé d'extrusion d'une barre métallique (1) dans lequel la barre coulée (1) quitte verticalement ou en arc de cercle une lingotière (2) par le bas et est ensuite amenée dans un guide-barre (3). Le guide-barre (3) présente plusieurs paires de rouleaux (4) qui définissent entre elles un interstice ajustable (5). Au début de la coulée, pour fermer la lingotière (2) dans le bas, une pièce de barre (6) est placée dans la lingotière (2) et la barre coulée (1) s'y raccorde. Pour améliorer l'ajustement de l'interstice entre rouleaux, il est prévu selon l'invention d'utiliser la pièce de barre (6) fabriquée à une épaisseur (d) définie et calibrée pour calibrer et/ou mesurer l'interstice (5) entre rouleaux de chaque paire de rouleaux.
