Abstract
La presente domanda ha per oggetto il procedimento per la riparazione di forni particolarmente atti alla fusione del vetro. La prima fase prevede lo scarico del vetro fuso a temperatura prossima a quella di fusione; segue la seconda fase che prevede il monitoraggio dell'interno del forno, mantenendo lo stesso a temperatura medio-alta per favorire il drenaggio del vetro fuso. La terza fase prevede il lavaggio delle zone consumate, mediante apposite lance irroranti solfato di sodio o altro materiale atto a fondere i residui di vetro; la quarta fase prevede l'abbassamento della temperatura del forno, fino a raggiungere circa (1150-1450)°C; la quinta fase prevede un raffreddamento localizzato delle sole zone erose da riparare, eventualmente delimitando queste ultime attraverso il posizionamento di refrattario. La sesta fase prevede l'apposizione di piccoli strati contigui di pigiata liquida con sovrapposizione, sino al livellamento, delle zone erose, prevedendo eventualmente l'aggiunta di refrattario frantumato a pezzatura predefinita. A questo punto si può effettuare il ripristino del tomo riportando lo stesso alla temperatura di fusione.
