Graphite electrode waxaa loola jeedaa coke batroolka, coke irbadda sida alaabta ceeriin, daamurka dhuxusha ee xabagta, ka dib markii alaabta ceeriin calcined, shiidi jabay, qaso, cajiin, qaabaynta, calcination, impregnation, graphite iyo farsamaynta farsamaysan oo ka samaysan nooc ka mid ah caabbinta heerkulka sare. graphite conductive walax, oo loo yaqaan graphite electrode macmal ah (oo hadda loo tixraaco sida graphite electrode), si ay uga soocaan garaafyada dabiiciga ah sida diyaarinta alaabta ceeriin ee electrode graphite dabiiciga ah. Marka loo eego tusmaheeda tayada, waxa loo qaybin karaa korantada graphite-ka caadiga ah, korantada graphite ee awooda sare iyo ultra-high power graphite electrode.
Electrode graphite awood sare waxa uu ka samaysan yahay coke batroolka oo tayo sare leh (ama coke coke coke fasalka hoose), mararka qaarkood jidhka electrode u baahan yahay in la impregnation, ay sifooyinkiisa jireed iyo farsamo ayaa ka sarreeya korontada caadiga ah graphite electrode, sida resistivity hoose, jidaynayey weyn oo weyn. cufnaanta hadda.
Korantada garaafyada awoodda sare waxay u oggolaaneysaa isticmaalka cufnaanta hadda jirta ee 18 ~ 25A / cm2 graphite electrode, oo inta badan loo isticmaalo samaynta birta foornada awoodda sare leh.
Bir-samaynta foornada korontadu waa isticmaale weyn oo ah electrodes graphite. Wax-soo-saarka birta eAF ee Shiinaha waxa ay ka dhigan tahay 18% wax-soo-saarka birta cayriin, iyo korantada graphite ee loo isticmaalo samaynta birta waxay xisaabisaa 70% ~ 80% wadarta tirada korantada garaafyada. Bir-samaynta foornada korontada waa isticmaalka graphite electrode galay foornada hadda, isticmaalka darafyada korantada iyo kharashka u dhexeeya arc ay dhaliso isha kulaylka sarreeya si ay u dhalaaliso.
foornada Arc waxaa inta badan loo isticmaalaa soo saarista fosfooraska jaalaha ah ee warshadaha iyo Silicon, iwm., dabeecadeeda waa qaybta hoose ee korantada korantada ee lagu aasay kharashka foornada, arc oo ka dhex abuurmay lakabka walxaha, oo u adeegso kharashka foornada lafteeda iska caabbinta. tamarta kulaylka si loo kululeeyo foornada foornada, mid ka mid ah cufnaanta sare ee hadda loo baahan yahay - foornada arc waxay u baahan tahay electrode graphite, sida silikoon 1 t halkii wax soo saar si ay u isticmaasho graphite electrode waa qiyaastii 100 kg, Qiyaastii 40kg of graphite electrode ayaa loo baahan yahay si loo soo saaro 1t fosfooraska jaalaha ah.
Foornada graphitization ee soo saarista alaabta graphite, foornada dhalaalka ee dhalada dhalada iyo foornada korontada ee soo saarista carbide silicon waxay ka tirsan tahay foornada iska caabinta. Waxyaabaha foornada ku jira waa labadaba caabbinta kuleylka iyo shayga kuleylka. Sida caadiga ah, korantada graphite conductive waxaa gundhig derbiga foornada dhamaadka foornada iska caabin ah, iyo graphite electrode waxaa loo isticmaalaa isticmaalka joogtada ah halkan.
Electrode graphite maran waxa kale oo loo istcimaalay farsamaynta crucible kala duwan, caaryada, doonta iyo jidhka kululaynta iyo alaabada kale ee garaafyada qaabaysan ee gaarka ah. Tusaale ahaan, warshadaha galaaska quartz, 10T ee graphite electrode billet ayaa loo baahan yahay 1T kasta oo soosaarka tuubada fiyuuska korontada; 100kg oo ah billet graphite electrode billet ayaa loo baahan yahay si loo soo saaro leben quartz 1t ah.
Laga bilaabo bilawga rubuca afraad ee 2016, iyada oo kor loo qaadayo siyaasadaha dib-u-habaynta saadka ee warshadaha birta iyo birta, burburinta birta sagxadda ayaa si lama filaan ah u noqotay mudnaanta ugu sareysa ee baabi'inta awoodda wax soo saarka ee dib u dhaca. Janaayo 10, 2017, Agaasime ku xigeenka Guddiga Horumarinta iyo Dib-u-habeynta Qaranka ayaa sheegay in shirka Golaha 2017 ee CISA in dhammaan baararka sagxadda laga saaro ka hor Juun 30, 2017. 2017, wadarta guud ee Shiinaha ee birta eAF waxay ahayd 120 milyan oo tan. , kuwaas oo 86.6 milyan oo tan ka mid ahi ay ahaayeen wax-soo-saar iyo 15.6 milyan oo tan oo wax-soo-saar ah. Dhamaadkii Oktoobar 2017, awoodda wax-soo-saarka eAF waxay ahayd qiyaastii 26.5 milyan tan, taas oo ku saabsan 30% dib loo bilaabay. Iyada oo ay saameynayso hoos u dhigista awoodda foornada soo noqnoqda ee dhexdhexaadka ah, birta foornada korontada ayaa si firfircoon loo bilaabay, faa'iidada dhaqaale ee foornada korontada ayaa caan ah. Birta foornada korontada waxay leedahay baahi wanaagsan oo loo qabo koronto sare iyo koronto graphite ah oo aad u sarreeya, iyo xamaasad iibsi oo sarreeya.
2017, qiimaha gudaha ee graphite electrode ayaa kor u kacay, iyo baahida dibadda ayaa kor u kacday. Suuqyada gudaha iyo dibaddaba waxay ku soo noqdeen barwaaqo. Shiinaha, sababtoo ah nadiifinta "birta sagxadda", kororka awoodda foornada korontada, xaddidaadda wax soo saarka ilaalinta deegaanka ee shirkadaha kaarboonka iyo arrimo kale, qiimaha korantada graphite ee gudaha ayaa cirka isku shareeray 2017, taasoo muujineysa in suuqa graphite electrode ee gudaha uu ku jiro sahay gaaban. Isla mar ahaantaana, kobaca korriinka graphite ee Shiinaha ayaa muujinaya in baahida koronto ee garaafyada dibedda ay tahay mid xooggan. Gudaha iyo dibaddaba waxay muujiyeen baahida xooggan ee electrodes graphite, warshadaha ayaa weli ku jira xaalad gaaban.
Sidaa darteed, soo jiidashada maalgashiga warshadaha korantada graphite ee awoodda sare ayaa weli ah mid xooggan.
Iyada oo horumarinta warshadaha birta iyo birta caalamiga ah, foornada arc koronto si tartiib tartiib ah u weyn, awoodda ultra-sare iyo kombuyuutar si toos ah gacanta iyo dhinacyada kale ee horumarinta, isticmaalka tamarta sare foornada arc koronto waa sii kordhaya, kor u codsiga ee graphite electrode awood sare. .
Marka la barbar dhigo Maraykanka, Europe, Japan iyo dalalka kale ee horumaray iyo gobollada, Shiinaha ee warshadaha graphite elektrode awood sare bilaabay goor dambe, inta badan ku tiirsan soo dejinta at ugu horrayn, wax soo saarka ee electrode graphite awood sare waa ka fog baahida. Iyada oo ay horseeday horumarinta warshadaha birta iyo birta iyo horumarka tignoolajiyada, Shiinuhu wuxuu si tartiib tartiib ah u jebiyey keli-taliska tignoolajiyada ee waddamada shisheeye, awoodda wax-soo-saarka ee korantada graphite ee awoodda sare ayaa kor u kacday, tayada wax soo saarka ayaa sidoo kale si degdeg ah loo hagaajiyay. Waqtigan xaadirka ah, korantada graphite ee awoodda sare leh ee laga soo saaro Shiinaha waxay ku guulaysatay natiijooyin wanaagsan oo ku saabsan foornada koronto ee baaxadda weyn, iyo dhammaan tusmooyinka waxqabadka ee alaabtu waxay gaari karaan heerka hogaaminta caalamiga ah. Alaabta korontada sare ee Shiinaha ee graphite electrode ma aha oo kaliya inay bixiso suuqa gudaha, laakiin sidoo kale tiro badan oo dhoofin ah oo loo dhoofiyo wadamada shisheeye, baahida alaabooyinka la soo dhoofiyo waa yar tahay.
Horumarinta birta foornada ee awoodda sare leh waa isbeddel muhiim ah oo horumarinta warshadaha foornada korontada ku shaqeeya. In mustaqbalka, wax soo saarka ee steelmaking foornada korontada korontada sare kordhin doonaa, iyo ay baahida loo qabo graphite electrode awood sare ayaa sidoo kale kordhin doona, kor u qaadida wax soo saarka ee graphite electrode awood sare ee Shiinaha. Shirkadaha korantada graphite ee awoodda sare ee gudaha waxay kordhin karaan silsiladda warshadaha, waxay sameeyaan cilmi baaris iyo horumarinta alaabta ceeriin, waxayna dhisaan qalabka wax soo saarka, kaas oo si wax ku ool ah u yareeyn kara kharashka ganacsiga iyo hagaajinta faa'iidada hawlgalka ee ganacsiga.
