Sababtoo ah graphite electrodes 'waxqabadka aad u fiican oo ay ku jiraan conductivity sare, caabbinta sare ee shoogga kulaylka iyo daxalka kiimikada iyo wasakh hoose, graphite electrodes waxay door muhiim ah ka ciyaaraan birta EAF inta lagu jiro warshadaha birta casriga ah iyo birta si ay u dalbadaan hufnaanta, yaraynta kharashka, iyo kor u qaadista joogtaynta.
Waa maxay Graphite Electrode?
GRAPHITE ELECTRODES waa qalabka ugu wanaagsan ee loo isticmaalo foornada arc koronto iyo foornada dhalaalaysa, Waxay soo saaraan cokes irbad tayo sare leh oo isku dhafan, la dubay, la dubay iyo habka garaafaynta si loo sameeyo alaabta la dhammeeyey. Waxay u adkeysan kartaa kulaylka ba'an iyada oo aan la jabin. Hadda waa badeecada kaliya ee la heli karo ee leh heerarka sare ee korantada iyo awoodda sii wadista kulaylka aadka u sarreeya ee ka dhasha jawiga baahida badan.
Habkani waxa uu yareeyaa khasaaraha tamarta waxana uu wanaajiyaa habka dhalaalidda oo dhan waxtarka, taasoo keentay in isticmaalka tamarta yar iyo hooseeyo kharashka wax soo saarka.
Garaafyada Electrode Guryaha Gaarka ah
GRAPHITE ELECTRODE waxay ku fiican tahay isticmaalka foornooyinka korontada ku shaqeeya iyo codsiyada kale ee warshadaha. Guryaha gaarka ah waxay hubiyaan in graphite electrode uu u adkeysan karo heerkul sare oo gaaraya 3,000 ° C iyo cadaadiska foornada arc korontada (EAF).
- Dhaqdhaqaaqa Kuleylka Sare- Electrodes-ka graphite waxay leeyihiin kuleyl heer sare ah, taas oo u sahlaysa inay u adkeystaan heerkulka sare iyo cadaadiska inta lagu jiro habka dhalaalka.
- Iska caabin Koronto oo hooseeya- Iska caabbinta korantada hoose ee graphite electrodes waxay fududaysaa socodka fudud ee tamarta korantada ee foornooyinka korantada.
- Xoogga Farsamada Sare- Electrodes-ka graphite waxaa loogu talagalay inay yeeshaan awood farsamo oo sareysa si ay ugu adkeystaan heerkulka sare iyo heerarka cadaadiska foornooyinka arc koronto.
- Iska caabin Kiimiko oo heersare ah- Graphite waa shay aan firfircoonayn oo adkaysi u leh inta badan kiimikooyinka iyo walxaha daxalka.Electrodes-ka graphite ee ku habboon in lagu isticmaalo jawiyada warshadaha qallafsan, halkaas oo walxaha kale laga yaabo inay ku fashilmaan weerarka kiimikada awgeed.
Electrodes graphite ma aha oo kaliya si ballaaran loo isticmaalo foornooyinka korontada ku shaqeeya, sidoo kale loo isticmaalo wax soo saarka ee biraha Silicon, fosfooraska jaalaha ah, iyo biraha kale ee non-ferrous, acids, alkalis, iyo kiimikooyinka kale, deegaanka daxalka.
Electrodes-ka graphite waxa loo kala saaraa saddex darajo iyadoo lagu salaynayo hantidooda jireed, tilmaamo iyo codsiyo kala duwan oo la xidhiidha awooda foornada korontada, culayska korontadu.Darajooyinka ugu badan ee la isticmaalo ee graphite electrodes waa Ultra-high power (UHP), Awood sare (HP), iyo Awood joogta ah (RP).
UHP graphite electrodes muujinta conductivity kaamerada sare iyo iska caabin korantada hoose, waxay si gaar ah loo isticmaalo ultra-sare korontada foornada qaansada (EAF) in dhalaalidda ee birta la safeeyey ama steel gaar ah.UHP graphite electrode ku haboon yahay awoodda foornada korontada waa 500 ~ 1200kV / Halkiiba.
HP Graphite Electrode waa sheyga ugu wanaagsan ee korantada ee foornada arc koronto iyo foornada dhalaalaysa, waxay u shaqeysaa sidii xamuul si ay u soo bandhigto hadda foornada. halkii tan.
RP graphite electrode waxaa si weyn loo isticmaalaa foornada korontada ee caadiga ah taas oo awood u leh agagaarka 300kV / A per ton ama ka yar. darajada RP ayaa ugu hooseeya kuleyliyaha iyo xoogga farsamada marka la barbar dhigo UHP graphite electrode iyo HP graphite electrode.RP graphite electrodes ayaa ku haboon. wax soo saarka biraha heerka hoose sida biraha, sifaynta silicon, sifaynta fosfooraska jaalaha ah, soo saaridda warshadaha galaaska.
Iyada oo baahida sii kordheysa ee ilaha tamarta kale, electrodes graphite ayaa sidoo kale door muhiim ah ka ciyaaraya horumarinta unugyada shidaalka.
Electrodes-ka graphite waxay leeyihiin codsiyo balaadhan oo kala duwan ee warshadaha kala duwan.Qaar ka mid ah codsiyada aasaasiga ah ee graphite electrode waxaa ka mid ah;
Foornada Arc Koronto (EAF) ee ku jirta Bir-samaynta
Codsiga korantada graphite ee samaynta birta EAF waa arrin muhiim u ah wax soo saarka birta casriga ah.Electrodes Graphite waa sida kirishbooyada si ay u bixiyaan korontada foornada, taas oo iyana soo saarta kulayl si ay u dhalaaliso steel. The EAF geedi socodka u baahan heerkulka sare si ay u dhalaali birta qashinka, electrodes graphite adkeysan karaan heerkul sare oo aan lumin ay qaabdhismeedka qaabdhismeed. wuxuu sii wadaa inuu diirada saaro hababka wax soo saarka waara oo hufan, electrodes graphite ayaa sii wadi doona inay door muhiim ah ka ciyaaraan birta EAF.
Foornada Ladle (LF)
Foornooyinka Ladle (LFs) waa qaybo muhiim ah oo ka mid ah habka samaynta birta.Electrodes graphite waxay leeyihiin sifooyin aad u fiican oo ay ku jiraan conductivity sare, caabbinta shoogga kulaylka iyo daxalka kiimikada, iyo cimri dheer, waxay yihiin doorashada ugu fiican ee foornada ladle (LF) codsiga.By isticmaalaya graphite electrodes, hawlwadeenada foornada ladle waxay gaari karaan hufnaan weyn, wax soo saarka. iyo wax-ku-oolnimada, iyadoo la ilaalinayo heerarka tayada sare leh ee warshaduhu dalbadaan.
Foornada Korontada ee Hoosaysa (SEF)
Electrodes-ka graphite ayaa si weyn loogu isticmaalaa foornada koronto ee hooseysa waa cunsur muhiim u ah soo saarista biro iyo walxo badan sida fosfooraska jaalaha ah, silicon saafi ah.Electrodes-ka graphite ayaa leh sifada ugu wanaagsan oo ay ka mid yihiin koronto-dhaliyaha sare, caabbinta sare ee shoogga kulaylka, iyo isku-dhafka hoose ee ballaarinta kulaylka.Astaamahani waxay ka dhigayaan korantada graphite ku habboon in lagu isticmaalo foornooyinka koronto ee hoostooda, halkaasoo heerkul aad u daran iyo xaaladaha adag ay yihiin kuwa caadiga ah.
Electrodes-ka graphite waa qaybo muhiim ah oo ku jira habka birta samaynta Foornada Arc (EAF).
