Abstract

Framgangsmåte for smelting av ferrosilisiumlegering, hvor en karbonkilde og returgods omfattende oksider av silisium og jem tilsettes en hovedsakelig lukket ovn, hvorved varme tilføres ovnen med en likestrømsbue slått mellom en katodelektrode og en anodefunksjonell bunn. I en foretrukket utførelsesform er katodelektroden hul, og føden til den hovedsakelig lukkete ovnen skjer gjennom den hule elektroden.
