Abstract

Processo e impianto per la riparazione della superficie refrattaria di convertitori caratterizzato dal fatto che la scoria presente in essi viene movimentata in modo da farla impattare in zone definite delle pareti refrattarie del convertitore stesso, detta movimentazione essendo ottenuta attraverso un flusso di gas che fluisce attraverso una pluralità di condotti posizionati all'interno della muratura refrattaria al di sotto del pelo libero della scoria.
