graphite electrodewaxaa inta badan loo isticmaalaa EAF birta samaynta. Bir-samaynta foornada korontada waa in la isticmaalo graphite electrode si loo soo geliyo hadda foornada. Hadda xoogga leh ayaa ka soo baxa gaaska xagga hoose ee korantada, kulaylka ay dhaliso arc waxaa loo isticmaalaa dhalaalinta. Marka loo eego awoodda foornada korontada, electrodes graphite oo leh dhexroor kala duwan ayaa loo isticmaalaa. Si loo sameeyo korantada si joogto ah loo isticmaalo, electrodes-yada waxay ku xiran yihiin isku-dhafka korantada. Thegraphite electrodesamaynta birta waxay ka dhigan tahay 70-80% wadarta guud ee korantada garaafyada. 2. Waxaa loo isticmaalaa foornada tamarta kulaylka ee macdanta. Dabeecaddeeda ayaa ah in qaybta hoose ee korantada korantada ay ku aasto kharashka. Sidaa darteed, marka lagu daro kulaylka ka soo baxa arc ee u dhexeeya saxanka korantada iyo kharashka, kulaylka ayaa sidoo kale keena caabbinta kharashka marka hadda la marayo kharashka. 3, foornada Graphitization, foornada dhalaalka galaaska iyo foornada korontada ee soo saarista alaabta graphite waa dhammaan foornooyinka iska caabinta. Qalabka ku jira foornada ma aha oo kaliya caabbinta kuleylka, laakiin sidoo kale walxaha kuleylka. Caadi ahaan, korantada graphite conductive waxaa la geliyaa gidaarka madaxa foornada dhamaadka teebka, sidaas darteed korantada korantada si joogto ah looma isticmaalo.
Goobaha codsiga:
(1) Waxaa loo isticmaalaa foornada birta samaynta ee korontada ku shaqeysa, taas oo ah isticmaale weyngraphite electrode. Dalka Shiinaha, wax-soo-saarka birta EAF wuxuu xisaabiyaa qiyaastii 18% soosaarka birta cayriin, iyo graphite electrode ee birta samaynta waxay xisaabisaa 70% ~ 80% wadarta isticmaalka korantada garaafyada. Bir-samaynta foornada korantada waa in la isticmaalo graphite electrode si ay u soo geliso hadda foornada, oo aad isticmaasho isha kulaylka sare leh ee ay dhaliso arc inta u dhaxaysa dhamaadka korantada iyo kharashka lagu dhalaalayo.
2) Waxaa loo isticmaalaa foornada arc hoosteeda; foornada arc quusta ayaa inta badan loo isticmaalaa soo saarista silikoon warshadeed iyo fosfooraska jaalaha ah, iwm. waxaa lagu gartaa in qaybta hoose ee korantada korantada ay ku duugan tahay kharashka, samaynta arc ee lakabka kharashka, iyo kuleylinta kharashka adoo isticmaalaya tamarta kulaylka. waxaa ka dhashay iska caabinta kharashka laftiisa. Foornada arc ee hooseysa ee cufnaanta sare ee hadda jirta waxay u baahan tahay graphite electrode, tusaale ahaan, qiyaastii 100kg graphite electrode ayaa loo baahan yahay wax soo saarka silikoon 1t, oo ku saabsan 100kg graphite electrode ayaa loo baahan yahay wax soo saarka silikoon 1t Qiyaastii 40 kg ee electrode graphite ayaa loo baahan yahay t huruud ah fosfooraska.
(3) Waxaa loo isticmaalaa foornada iska caabinta; foornada graphitization ee soo saarista alaabta graphite, foornada dhalada dhalada iyo foornada koronto ee soo saarista carbide silicon dhamaantood waxay iska leeyihiin foornada iska caabinta. Walxaha foornada ku jira labaduba waa caabbinta kuleylka iyo shay kulul. Guud ahaan, electrode graphite conductive waxaa gundhig in darbiga madaxa foornada dhamaadka foornada iska caabin ah, iyo graphite electrode halkan loo isticmaalo si joogto ah ma wada baabbi'iyey.
(4) Waxa loo isticmaalaa in lagu diyaariyo qaab gaar ahalaabta graphite; bannaan ee electrode graphite waxa kale oo loo isticmaalaa in lagu farsameeyo noocyo kala duwan oo alaabta graphite qaab gaar ah sida crucible, caaryada, saxan doonta iyo jidhka kululaynta. Tusaale ahaan, warshadaha galaaska quartz, 10t graphite electrode bannaan ayaa loo baahan yahay tuubo dhalaalaysa 1t kasta; 100kg graphite electrode maran ayaa loo baahan yahay leben kasta oo 1t quartz ah.
