Title (EN) THE INSPECTION OF CONTINUOUSLY CAST METALS
(FR) CONTROLE DES METAUX COULES EN CONTINU
Abstract:
(EN) A system for on-line monitoring of a continuous casting process to provide information about a continuously cast strand as a real-time event. The system comprises, a laser source for providing a pulsed laser beam incident on the surface of the strand to generate an acoustic wave in or on the surface of the strand, a detector for detecting the acoustic wave after the acoustic wave interacts with the strand, and for generating a signal representative of the state of the strand, and a processing means for analysing the signal generated by the detector.
(FR) Système de contrôle en direct d'un processus de coulée continue et servant à fournir en temps réel des informations relatives à un cordon coulé en continu. Le système comporte une source laser produisant un faisceau laser pulsé incident sur la surface du cordon pour générer une onde acoustique dans ou sur ladite surface, un détecteur destiné à détecter l'onde acoustique à la suite de son interaction avec le cordon, et à générer un signal représentatif de l'état de celui-ci, ainsi qu'un processeur destiné à analyser le signal généré par le détecteur.
