Abstract

Fremgangsmåten for separasjon av titan og/eller vanadi- um fra råjern omfatter i et første trinn at råjernet blandes med jernoksider i en mengde som er tilstrekke- lig for å forslagge titanet, at titanet forslagges og slaggen separeres, at det deretter tilføres jernoksider i en mengde som er tilstrekkelig for å forslagge vana- diumet, og at den vanadiumanrikede slagg separeres, hvoretter råjernet ferskes til stål.The process for separating titanium and / or vanadium from pig iron comprises, in a first step, mixing the pig iron with iron oxides in an amount sufficient to propose the titanium, proposing the titanium and separating the slag, then adding iron oxides in a amount sufficient to suggest the vanadium, and that the vanadium-enriched slag is separated, after which the iron is freshened to steel.
