Abstract

Allo scopo di mantenere libere un'apertura per il passaggio della lancia (1) che attraversa una parete di un recipiente metallurgico (3) e di evitare la formazione di depositi e sedimenti, questo sistema presenta un dispositivo (17) generatore di un getto di fiamma e/o di un getto di gas (18) che, mediante un dispositivo di spostamento (13), può essere spostato da una posizione di riposo a fianco dell'apertura per il passaggio della lancia (1) in una posizione di lavoro che chiude l'apertura per il passaggio della lancia (1) (Figura 3).In order to keep an opening free for the passage of the lance (1) that crosses a wall of a metallurgical vessel (3) and to avoid the formation of deposits and sediments, this system has a device (17) which generates a jet of flame and / or a jet of gas (18) which, by means of a displacement device (13), can be moved from a rest position alongside the opening for the passage of the lance (1) into a working position which closes the opening for the passage of the lance (1) (Figure 3).
