Title (EN) DEVICE AND METHOD FOR CONTROLLING NON-IRON MELTING PROCESS
(FR) DISPOSITIF ET PROCÉDÉ DE COMMANDE DE PROCESSUS DE FUSION NON FERREUX
Abstract: front page image
(EN)A furnace (10) for non-iron metals and a method of operating it are disclosed with a monitoring system (12) for monitoring in-situ the concentration of a passivation fluid,such as perfluoroketones in a cover gas(136). The monitoring system (12) includes a sensor (122) for determining an emission and/or an absorption of the passivation fluid at least one wavelength or wave- length band of the electromagnetic wave spectrum, with the measured concentration being used as a control input for a flow control system (13) controlling the supply of the cover gas (136) into the furnace (10).
(FR)L'invention concerne un four (10) pour métaux non ferreux et un procédé de fonctionnement de celui-ci, ayant un système de surveillance (12) pour surveillance in situ de la concentration d'un fluide de passivation, tel que des perfluorocétones dans un gaz de couverture (136). Le système de surveillance (12) comprend un capteur (122) pour déterminer une émission et/ou une absorption du fluide de passivation à au moins une longueur d'onde ou bande de longueur d'onde du spectre des ondes électromagnétiques, la concentration mesurée étant utilisée en tant qu'entrée de commande pour un système de commande de débit (13) qui commande l'alimentation du gaz de couverture (136) dans le four (10).
