Abstract

L'invention concerne un dispositif de détection optique des formes de produits métalliques laminés. Selon l'invention, le signal d'une caméra d'une télévision 5 surveillant le produit laminé 1 est transmis à une unité de commande 7, dont le signal de sortie est transmis à des unités 8 et 9 de correction ou compensation de signaux en fonction de la vitesse de laminage détectée par un capteur 6. L'invention permet d'améliorer les qualites des produits métalliques laminés.The invention relates to a device for optical detection of the shapes of rolled metal products. According to the invention, the signal from a camera of a television 5 monitoring the laminated product 1 is transmitted to a control unit 7, the output signal of which is transmitted to units 8 and 9 for correction or compensation of signals in function of the rolling speed detected by a sensor 6. The invention makes it possible to improve the qualities of rolled metal products.
