Abstract
Viene realizzato un metodo per controllo di condizioni di processo in un processo continuo ad ugello munito di crosta nel quale uno o più parametri di processo sono controllati per mantenere il funzionamento del processo entro una finestra di procedimento derivata usando soluzioni integrali ed espressa in termini di parametri adimensionali, la finestra di processo definendo una gamma di valori entro i quali verrà mantenuta una crosta solidificata stazionaria e fuori dai quali non verrà mantenuta la crosta solidificata stazionaria. Una differenza di pressione tra l'interno di un crogiolo contenente la fusione e l'esterno del crogiolo è un parametro di processo che viene controllato per regolare la portata di scarico della fusione allo scopo di mantenere il funzionamento entro la finestra di processo.
