Abstract
A találmány tárgya egyenáramú ívkemence acél előállítására, amelylegalább két, villamos ív létrehozására alkalmas elektróddal, továbbáaz olvadék és a salak számára kialakított csapolónyílásokkal, valaminta füstgázok közvetlen szabályozására alkalmas eszközökkel ellátottolvasztóedényt tartalmaz. A találmány tárgyát képezi továbbá egyeljárás acél előállítására egy ilyen ívkemencében. A találmányszerinti egyenáramú ívkemence újdonsága az, hogy a betétanyagot (11)az olvasztóedénybe (2) bevezető központi adagolóakna (10)szomszédságában az olvasztóedény (2) felső részében a betétanyag (11)beadagolási folyamata során keletkező por és/vagy gázok elszívásáraalkalmas olvasztóedény-elszívó berendezéseket (3.2) befogadó nyílásokvannak kialakítva, ahol egy, az aknában (10) elrendezett aknaelszívóberendezés (3.1) és az olvasztóedény-elszívó berendezés (3.2) egyközös füstgázelvezető szerkezetté (3) van összekötve és aholátkapcsoló elemek vannak beépítve mindig csak az egyik elszívóberendezés működtetésére és/vagy a füstgázáramlatok valamelykombinációjának beállítására a mindenkori beadagolási vagybeolvasztási folyamattól függően. A fenti ívkemencében megvalósítotttalálmány szerinti eljárásra az jellemző, hogy a beadagolás alatt azennek során keletkező gázokat és port egy, az olvasztóedény (2) felsőrészében kialakított nyílásokkal összekötött olvasztóedény-elszívóberendezéssel (3.2) elszívják, ugyanakkor a füstgázokat azolvasztóedény-elszívó berendezésből (3.2) és az aknaelszívóberendezésből (3.1) egy közös füstgázelvezető szerkezet (3)segítségével távolítják el.
