Abstract

Bir arkli firin (1) içinde eritilecek olan bir malin (5) kismen düsük yanisinda arkli firinin (1) iç duvarlarinda bir hasarin meydana gelmesini ve elektrikli performansin geri alinisini engellemek için, sözkonusu bu kritik erime safhasi sirasinda bir ortasi kanalli elektrodun (17) doldurma deliginin bir dökme mal sevkedicisi (25) vasitasiyla ilave maddeler (10) eklenmektedir. Bu sayede arkli firin içinde (1) ortasi oluklu elektrot (7) ile bir eriyik (4) arasinda bir ark (6) kisalmaktadir. Bir dökme mal kabi (9) dökme mal sevkedicisinin (25) elektroda uzak ucuna tertip edilmistir ve ortasi kanalli elektrottan (7) arkli firinin (1) eriyigin (4) bosaltilmasi için devrilmesini mümkün kilacak sekilde ayrilabilmektedir. Ilave maddeler (10) imha edilecek, problematik atik maddelere, örnek olarak filtre tozuna ilave edilmektedir.
