Abstract
L'invenzione riguarda un procedimento, per riparare un cubilotto a vento caldo, ove dopo la fine della fusione viene raffreddato il cubilotto ed il suo sifone, quindi viene rotta la loppa residua e viene rivestita con un materiale resistente alla fiamma. Per ottenere un tempo di riparazione di molto ridotto e per permettere un rinnovato rivestimento a temperature normali, è previsto che venga raffreddato con azoto liquido e che contemporaneamente venga effettuata la rottura con un apparecchio comandato a distanza.
