The invention relates to a method for precisely positioning a plurality of interacting roller or cylindrical elements (2, 3, 4) of a rolling or casting installation (1) in relation to each other. In order to allow a rapid and precise adjusting of the roller or cylindrical elements, the distance (a6, a7, a8, a9) between at least three reference points (6, 7, 8, 9) arranged on every of the roller or cylindrical elements (2, 3, 4) and the measuring device (5) is measured using said measuring device (5) and adjusting elements (10, 11, 12) on every roller or cylindrical element (2, 3, 4) are actuated, depending on the result of measurement, in such a manner that the distances (a6, a7, a8, a9) between the reference points (6, 7, 8, 9) and the measuring device (5) correspond to each other to a maximum, the measuring points (6, 7, 8, 9) of every roller or cylindrical element (2, 3, 4) being arranged directly or indirectly on a support element (13) of the roller or cylindrical element (2, 3, 4). The invention also relates to a rolling or casting installation, especially for carrying out the inventive method.

L'invention concerne un procédé pour positionner avec précision un certain nombre de rouleaux ou d'éléments de laminage coopérants (2, 3, 4) d'un dispositif de laminage ou de coulée (1) les uns par rapport aux autres. L'objectif de cette invention est de permettre une installation rapide et précise des rouleaux ou éléments de laminage. A cet effet, la distance (a<SUB>6</SUB> a<SUB>7</SUB>, a<SUB>8</SUB>, a<SUB>9</SUB>) entre au moins trois points de référence (6, 7, 8, 9), placés au niveau de chacun des rouleaux ou éléments de laminage (2, 3, 4), et l'appareil de mesure (5) est mesurée au moyen d'un appareil de mesure (5) et, en fonction du résultat de mesure, des éléments de réglage (10, 11, 12) sont actionnés au niveau de chaque rouleau ou élément de laminage (2, 3, 4), de sorte que les distances (a<SUB>6</SUB>, a<SUB>7</SUB>, a<SUB>8</SUB>, a<SUB>9</SUB>) entre les points de référence (6, 7, 8, 9) et l'appareil de mesure (5) coïncident le mieux possible avec des valeurs prédéfinies, les points de mesure (6, 7, 8, 9) d'un rouleau ou élément de laminage (2, 3, 4) étant directement ou indirectement associés à un élément de support (13) du rouleau ou de l'élément de laminage (2, 3, 4). Cette invention concerne également un dispositif de laminage ou de coulée, en particulier pour la mise en oeuvre dudit procédé.
