Title
(EN) METHOD AND SYSTEM FOR RACEWAY DEPTH CONTROL IN A BLAST FURNACE
(FR) PROCÉDÉ ET SYSTÈME DESTINÉS À LA COMMANDE D'UNE PROFONDEUR DE CHEMIN DE ROULEMENT DANS UN HAUT-FOURNEAU
Abstract
(EN)
The invention relates to a method for raceway depth control in a blast furnace, comprising controlling a hot blast flow through a tuyere by means of a control system, the control system carrying out a raceway depth measurement through the tuyere by means of a radar sensor, the radar sensor sending the raceway depth measurement to the control system, the control system comparing the raceway depth measurement with a predetermined raceway depth, wherein the control system carrying out the raceway depth measurement through a plurality of tuyeres by means of a plurality of radar sensors divided over the circumference of the blast furnace.
(FR)
La présente invention concerne un procédé de commande de profondeur de chemin de roulement dans un haut-fourneau consistant à commander un flux de vent chaud à travers une tuyère au moyen d'un système de commande, le système de commande mettant en œuvre une mesure de profondeur de chemin de roulement à travers la tuyère au moyen d'un capteur radar, le capteur radar envoyant la mesure de profondeur de chemin de roulement au système de commande, le système de commande comparant la mesure de profondeur de chemin de roulement à une profondeur de chemin de roulement prédéterminée, le système de commande mettant en œuvre la mesure de profondeur de chemin de roulement par le biais d'une pluralité de tuyères au moyen d'une pluralité de capteurs radar divisés sur la circonférence du haut-fourneau.
