Title

(EN) SHIELDED INSPECTION SYSTEM FOR GATHERING PROCESS INFORMATION WITHIN A FURNACE

(FR) SYSTÈME D'INSPECTION PROTÉGÉ POUR COLLECTER DES INFORMATIONS DE PROCESSUS À L'INTÉRIEUR D'UN FOUR

Abstract

(EN) A method for obtaining a process information within a furnace environment, the method including steps of directing a first gas jet into a molten metal charge within the furnace to locally displace a portion of upper material layer located on top of a lower material layer in order to expose the top portion of the lower material layer, using an inspection device to obtain said information from the exposed portion of the lower material layer, and then processing the obtained information to provide furnace process regulating parameters. The method further comprises a step of shielding the inspection device by using a second jet of a shielding and cooling second gas, said first and second jets being coaxially disposed relative to each other along the inspection device longitudinal axis.

(FR) L'invention concerne un procédé d'obtention d'informations de processus dans un environnement de four, le procédé comprenant les étapes consistant à diriger un premier jet de gaz dans une charge de métal en fusion à l'intérieur du four pour déplacer localement une partie de la couche de matériau supérieure située au-dessus d'une couche de matériau inférieure afin d'exposer la partie supérieure de la couche de matériau inférieure, à utiliser un dispositif d'inspection pour obtenir lesdites informations à partir de la partie exposée de la couche de matériau inférieure, puis à traiter les informations obtenues pour fournir des paramètres de régulation de processus de four. Le procédé comprend en outre une étape de protection du dispositif d'inspection à l'aide d'un second jet d'un second gaz de protection et de refroidissement, lesdits premier et second jets étant disposés coaxialement l'un par rapport à l'autre le long de l'axe longitudinal du dispositif d'inspection.
