Elektroodka Graphite waxaa loola jeedaa kookaha batroolka, kookaha irbadda sida walax ceeriin ah, daamurka dhuxusha ee dhejisyada, ka dib marka la kariyo walaxda ceeriin, la shiido, la isku qaso, la isku qurxiyo, la isku qurxiyo, la isku qurxiyo, la isku daaro, la isku qurxiyo, la isku qurxiyo, la isku qurxiyo, la isku qurxiyo, la isku qurxiyo, la isku dhejiyo, la isku dhejiyo iyo farsamaynta farsamada waxaana laga sameeyay nooc ka mid ah iska caabinta heerkulka sare ee walaxda gudbisa graphite, oo loo yaqaan electrode graphite macmal ah (halkan loogu yeero electrode graphite), si looga sooco graphite dabiiciga ah sida diyaarinta walxaha ceeriin ee elektroodka graphite dabiiciga ah. Sida ku cad tusmada tayada, waxaa loo qaybin karaa elektroodka graphite ee awoodda caadiga ah, elektroodka graphite ee awoodda sare leh iyo elektroodka graphite ee awoodda sare leh.
Elektroodka garaafiga ee awoodda sare leh waxaa laga sameeyaa soo saarista kookaha batroolka ee tayada sare leh (ama kookaha irbadda ee heerka hoose), mararka qaarkood jirka elektroodka wuxuu u baahan yahay in la qooyo, sifooyinkiisa jireed iyo kuwa farsamo ayaa ka sarreeya elektroodka garaafiga ee awoodda caadiga ah, sida iska caabinta hoose, taasoo u oggolaanaysa cufnaan hadda jirta oo weyn.
Elektroodka garaafiga ee awoodda sare leh wuxuu u oggolaanayaa isticmaalka cufnaanta hadda jirta ee elektroodka garaafiga ee 18 ~ 25A/cm2, oo inta badan loo isticmaalo sameynta birta foornada ee awoodda sare leh.
Samaynta birta foornada korontada ku shaqeysa waa mid si weyn u adeegsata elektroodhada garaafka. Wax soo saarka birta eAF ee Shiinaha wuxuu ka yahay qiyaastii 18% wax soo saarka birta cayriin, elektroodka garaafka ee loo isticmaalo sameynta birta wuxuu ka yahay 70% ~ 80% wadarta guud ee elektroodka garaafka. Sameynta birta foornada korontada ku shaqeysa waa isticmaalka elektroodka garaafka ee loo geliyo qulqulka foornada, isticmaalka xad-dhaafka korantada iyo dallacaadda u dhaxaysa qaansada ay soo saarto isha kulaylka heerkulka sare ilaa dhalaalka.
Foornada -arc waxaa inta badan loo isticmaalaa soo saarista fosfooraska jaalaha ah ee warshadaha iyo siliconka, iwm., astaamaheeda waa qaybta hoose ee elektroodka gudbiyaha ee lagu aasay foornada, qaansada lagu sameeyay lakabka agabka, oo isticmaal foornada lafteeda laga bilaabo iska caabbinta tamarta kulaylka ilaa foornada kululaynta, mid ka mid ah cufnaanta hadda jirta ee sare loo baahan yahay - foornada qaansada waxay u baahan tahay elektroodka garaafka, sida silicon 1 t wax soo saar kasta ilaa isticmaalka elektroodka garaafka waa qiyaastii 100 kg, Qiyaastii 40kg oo elektroodka garaafka ayaa loo baahan yahay si loo soo saaro 1t fosfooraska jaalaha ah.
Foornada garaafka ee loogu talagalay soo saarista alaabada garaafka, foornada dhalaalaysa ee loogu talagalay dhalooyinka dhalaalaya iyo foornada korontada ku shaqeysa ee loogu talagalay soo saarista carbide-ka silicon waxay ka tirsan yihiin foornada iska caabbinta. Waxyaabaha ku jira foornada waa iska caabbinta kulaylka iyo shayga kululaynta. Caadiyan, elektroodka garaafka ee gudbiya ayaa ku dhex jira derbiga foornada ee dhammaadka foornada iska caabbinta, elektroodka garaafkana waxaa loo isticmaalaa isticmaalka aan kala joogsiga lahayn halkan.
Elektroodka graphite-ka ee madhan ayaa sidoo kale loo isticmaalaa farsamaynta noocyo kala duwan oo ah walxaha la shiilay, caaryada, doonyaha iyo qalabka kululaynta iyo alaabada kale ee qaabaysan ee graphite. Tusaale ahaan, warshadaha galaaska quartz, 10T oo ah billet elektroodka graphite ayaa loo baahan yahay 1T kasta oo wax soo saar tuubo fiyuus koronto ah; 100kg oo billet elektroodka graphite ah ayaa loo baahan yahay si loo soo saaro leben quartz ah oo 1t ah.
Laga bilaabo bilowgii rubuci afraad ee 2016, iyadoo la horumarinayo siyaasadaha dib-u-habaynta dhinaca saadka ee warshadaha birta iyo birta, burburinta birta dabaqa ayaa si lama filaan ah u noqotay mudnaanta koowaad ee baabi'inta awoodda wax soo saarka ee dib u dhaca. Janaayo 10, 2017, Agaasime ku xigeenka Guddiga Horumarinta iyo Dib-u-habaynta Qaranka ayaa ka sheegay shirkii Golaha ee 2017 ee CISA in dhammaan baararka dabaqa laga saaro ka hor Juun 30, 2017. Sannadkii 2017, awoodda guud ee Shiinaha ee birta eAF waxay ahayd qiyaastii 120 milyan oo tan, kuwaas oo 86.6 milyan oo tan ay wax soo saar ahaayeen halka 15.6 milyan oo tan ay ka baxeen wax soo saarkii. Ilaa dhammaadka Oktoobar 2017, awoodda wax soo saarka ee eAF waxay ahayd qiyaastii 26.5 milyan oo tan, kuwaas oo qiyaastii 30% dib loo bilaabay. Iyada oo ay saamaysay hoos u dhaca awoodda foornada soo noqnoqoshada dhexdhexaadka ah, birta foornada korontada ayaa si firfircoon loo bilaabay, faa'iidada dhaqaale ee birta foornada korontada ayaa muuqata. Birta foornada korontada waxay leedahay baahi wanaagsan oo loogu talagalay koronto sare iyo koronto graphite awood sare leh, iyo xamaasad iibsi oo sare.
Sannadkii 2017, qiimaha gudaha ee elektroodka garaafiga ayaa kor u kacay, baahida dibaddana way korodhay. Suuqyada gudaha iyo dibaddaba waxay ku soo laabteen barwaaqo. Shiinaha, sababtoo ah nadiifinta "birta dabaqa", kororka awoodda foornada korantada, xadka wax soo saarka ilaalinta deegaanka ee shirkadaha kaarboonka iyo arrimo kale, qiimaha elektroodka garaafiga gudaha ayaa cirka isku shareeray sannadkii 2017, taasoo muujinaysa in suuqa elektroodka garaafiga gudaha uu gabaabsi yahay. Isla mar ahaantaana, kobaca elektroodka garaafiga Shiinaha wuxuu muujinayaa in baahida elektroodka garaafiga dibadda ay xooggan tahay. Gudaha iyo dibaddaba waxay muujiyeen baahi xooggan oo loo qabo elektroodka garaafiga, warshaduhu wali waxay ku jiraan xaalad sahay yar.
Sidaa darteed, soo jiidashada maalgashiga warshadaha elektroodka graphite ee awoodda sare leh ayaa weli xooggan.
Iyadoo la horumarinayo warshadaha birta iyo birta adduunka, foornada korantada si tartiib tartiib ah u gaarsiisan kontoroolka otomaatiga ah ee kombiyuutarka iyo dhinacyo kale oo horumarineed, isticmaalka foornada korantada ee awoodda sare leh ayaa sii kordhaya, taasoo kor u qaadaysa isticmaalka elektroodka graphite ee awoodda sare leh.
Marka la barbardhigo Mareykanka, Yurub, Japan iyo dalalka kale ee horumaray iyo gobollada kale, warshadaha elektroodka graphite ee awoodda sare leh ayaa bilaabmay goor dambe, iyadoo inta badan ku tiirsan soo dejinta ugu horreysa, soo saarista elektroodka graphite ee awoodda sare leh aad bay uga fog tahay baahida. Iyada oo ay horseedday horumarinta warshadaha birta iyo birta iyo horumarka tignoolajiyada, Shiinuhu wuxuu si tartiib tartiib ah u jebiyey keli-talisnimada tignoolajiyada ee waddamada shisheeye, awoodda wax-soo-saarka elektroodka graphite ee awoodda sare leh ayaa kor u kacaysay, tayada badeecadduna si degdeg ah ayaa loo hagaajiyay. Waqtigan xaadirka ah, elektroodka graphite ee awoodda sare leh ee laga soo saaro Shiinaha ayaa natiijooyin wanaagsan ka gaaray foornada korantada ee baaxadda weyn, dhammaan tusmooyinka waxqabadka ee badeecaddu waxay gaari karaan heerka hoggaamineed ee caalamiga ah. Badeecadaha elektroodka graphite ee awoodda sare leh ee Shiinaha ma aha oo kaliya inay bixiyaan suuqa gudaha, laakiin sidoo kale tiro badan oo dhoofinta loo diro waddamada shisheeye, baahida loo qabo badeecadaha la soo dejiyo way yar tahay.
Horumarinta sameynta birta foornada ilaa heer sare waa isbeddel muhiim ah oo ku yimid horumarinta warshadaha sameynta birta foornada korontada. Mustaqbalka, wax soo saarka sameynta birta foornada korontada ee awoodda sare leh ayaa kordhi doona, baahideedana loo qabo koronto graphite awood sare leh ayaa sidoo kale kordhi doonta, taasoo kor u qaadaysa soo saarista koronto graphite awood sare leh oo Shiinaha ah. Shirkadaha korontada graphite ee awoodda sare leh ee gudaha waxay ballaarin karaan silsiladda warshadaha, waxay sameyn karaan cilmi-baaris iyo horumarin alaabta ceeriin ah, waxayna dhisi karaan qalabka wax soo saarka, taas oo si wax ku ool ah u yareyn karta kharashyada ganacsiga iyo hagaajinta faa'iidada hawlgalka ganacsiga.
