Abstract

POSTUPAK ZA KONTINUIRANU PROIZVODNJU ČELIKA, naznačen time, što se sirovine kao što su isečeni otpaci koji sadrže gvoždje, granule direktno redukovanog gvoždja, materijal za obrazovanje zgure i materijal za legiranje, predgreju na 800 C do 1000 C toplim izlaznim reakcionim gasovima i uvode u električnu peć za topljenje gde se uz uvodjenje sredstava za karburiranje vrši zagrevanje električnim putem i uz topljenje punjenja obrazuje se kupatilo rastopljenog metala, pri čemu se zgura održava u penušavom stanju, što se za sve vreme operacije Idržava puna električna snaga i što se uz kontinuiranu napajanje vrši i izlivanje metala iz peći tako da se odvodi približno polovina istopljenog metalnog kupatila. Prijava sadrži još 6 patentnih zahteva.
