Abstract

A találmány tárgya eljárás 1,5-4,5 tömeg% széntartalmú olvasztott vaselőállítására oly módon, hogy (a) vas-oxidot és széntartalmúredukálószert készítenek elő; (b) formázott terméket készítenek aszéntartalmú redukálószerből és a vas-oxidból; (c) a formázotttermékből szilárd redukált vasat állítanak elő, ahol a szilárdredukált vas metallizációja legalább 60%, sűrűsége legalább 1,7 ésszéntartalma a szilárd redukált vasban maradó vas-oxid redukálásáhozszükséges elméleti mennyiség legalább 50 tömeg%-a; és (d) mielőttlényeges lehűlés történne, a szilárd redukált vasat ívfűtésűolvasztókemencében magas hőmérsékleten hevítik.
