Abstract

Miglioramenti nel processo di fabbricazione continua di elettrodi privi di impurità e di ferro, per forni ad arco elettrico, il quale comprende un meccanismo, il quale permette di cambiare (sostituire) il tipo di elettrodo, anche quello tradizionale a carbone amorfo (3), riducendo al minimo le soste del forno, il quale permette lo scorrimento dell'elettrodo (2) senza ghiera metallica (40) oppure con essa (40), costituito da una piastra di contatto 8 speciale, per la trasmissione della corrente elettrica, che riduce, in modo notevole, la superficie di contatto e nel processo operativo (6) per mantenere l'adeguata altezza delle placche di contatto. E' raccomandabile, in modo speciale, per l'ottenimento continuo di silicio metallo privo d'impurità.
