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).
