Patent

CA 2439543

A method and a device for weighing the contents of a metallurgical vessel (2), especially the contents of a tundish (3) in a steel continuous casting plant, whereby the vessel is supported on hydraulically actuatable weighing elements serving to increase the measurement precision before and during the metallurgical process and resides in that the filling weight is calculated by computer from hydraulic pressures in cylinder chamber (8a; 9a; 10a; 11a) which are measured deducting the empty weight of the vessel (2) and the friction forces in the cylinder chambers (8a; 9a; 10a; 11a).

L'invention concerne un procédé et un dispositif de pesage du contenu d'un récipient métallurgique (2), notamment du contenu d'un chenal distributeur (3) dans des systèmes de coulée continue d'acier, le récipient (2) s'appuyant sur des éléments de pesage pouvant être actionnés hydrauliquement. Le procédé et le dispositif selon l'invention servent à augmenter la précision de mesure avant et pendant le processus métallurgique et sont caractérisés en ce que le poids de remplissage est déterminé en continu par ordinateur, sur la base de pressions hydrauliques régnant dans des chambres cylindriques (8a; 9a; 10a; 11a), mesurées avec soustraction du poids à vide du récipient (2) et des forces de frottement dans les chambres cylindriques (8a; 9a; 10a; 11a) et/ou dans des guides verticaux.
