Abstract
L'invention concerne un système de contrôle d'un laminoir de barres ou tiges, ayant une cage principale et une cage de finissage avec des axes mutuellement perpendiculaires, pour faire varier l'écartement des cylindres et pour les aligner axialement dans la cage de finissage. Selon l'invention, une jauge 1051 mesure le profil latéral de la barre 10 sur son pourtour et applique ces données à un calculateur 27, qui reçoit également les données des variations longitudinales du profil à des diamètres prédéterminés de la barre. Il utilise ces données pour calculer un profil de diamètre optimum et calcule les ajustements des cylindres de ces cages 10 et 1011 pour obtenir ce profil optimum. Si ces ajustements permettent d'obtenir une amélioration sensible de la performance du laminoir, ils sont effectués. L'invention s'applique notamment aux aciéries.
