Abstract

Pronalazak se odnosi na postupak za pokrivanje elektricnog luka (22) koji gori u jednoj elektrolucnoj peci (10) pomocu penaste troske (S) koja se obrazuje unosenjem nosaca ugljenika u trosku koja se nalazi iznad rastopine (M) celika, pri cemu se hvata emisija zvuka i koristi se za upravljanje unosenja penastog uglja. Pri tome se spektar amplituda zvuka pri obrazovanju odredjuje kao prasak (praskava emisija zvuka). Amplitude se povezane sa praksom proracunavaju, dovode na jedan slican nivo i odvode u jedan racunar (43). U racunaru (43) se proracunate merne velicine primenjuju za regulisanje penaste troske S i koriste se kod prekoracenja ili podbacaja jedne unapred date vrednosti za regulisanje uredjaja (32, 33) za dovodjenje nosilaca ugljenika za penusanje troske. Pronalazak se odnosi i na jedan odgovarajuci pogodan uredjaj.
