Suuqa graphite electrode, oo hoos u dhacay sannadkii hore, ayaa sameeyay isbeddel weyn sanadkan.
"Qaybtii hore ee sanadka, electrodes-ka garaafyada ayaa asal ahaan gabaabsi ahaa." Maaddaama farqiga suuqa ee sanadkan uu yahay ilaa 100,000 oo tan, waxaa la filayaa in xidhiidhkan adag ee u dhexeeya saadka iyo baahida uu sii socon doono.
Waxaa la fahamsan yahay in tan iyo bishii Janaayo ee sanadkan, qiimaha graphite electrode uu si joogto ah u kacayay, laga bilaabo 18,000 yuan / ton bilowgii sanadka ilaa 64,000 yuan / ton hadda, iyada oo korodhka 256%. Isla mar ahaantaana, kookaha irbadda, oo ah alaabta ugu muhiimsan ee graphite electrode, ayaa noqotay mid gabaabsi ah, qiimihiisuna wuxuu kor u kacayay dhammaan habka, kaas oo kor u kacay in ka badan 300% marka la barbardhigo bilawga sanadka.
Baahida ganacsiyada birta ee hoose waa mid xoogan
Graphite electrode waxaa inta badan laga sameeyaa coke petroleum iyo coke irbadda sida alaabta ceeriin iyo garoonka daamurka dhuxusha sida binder, waxaana inta badan loo isticmaalaa foornada steelmaking Arc, foornada arc quusin, foornada iska caabin ah, iwm. 80% wadarta guud ee isticmaalka graphite electrode.
2016, hoos u dhaca ku yimid birta EAF awgeed, waxtarka guud ee shirkadaha kaarboonka ayaa hoos u dhacay. Marka loo eego tirakoobyada, wadarta guud ee iibka ee elektiroonigga graphite ee Shiinaha ayaa hoos u dhacay 4.59% sanad-sanadka 2016, iyo wadarta khasaaraha ee tobanka shirkadood ee ugu sarreeya ee elektiroonigga ah waxay ahaayeen 222 milyan yuan. Shirkad kasta oo kaarboon ah waxay la dagaallameysaa dagaal qiimo leh si ay u ilaaliso saamigeeda suuqa, iyo qiimaha iibka graphite electrode aad ayuu uga hooseeyaa qiimaha.
Xaaladdan ayaa dib loo rogay sanadkan. Iyada oo qoto dheer ee dib-u-habaynta dhinaca sahayda, warshadaha birta iyo birta ayaa sii waday inay soo qaadaan, iyo "xajinta birta" iyo foornooyinka inta jeer ee dhexdhexaadka ah ayaa si fiican loo nadiifiyey oo lagu hagaajiyay meelo kala duwan, baahida foornooyinka korontada ee shirkadaha birta ayaa kordhay si xoog leh, sidaas awgeedna baahida loo qabo electrodes graphite, iyada oo lagu qiyaasay baahida sanadlaha ah ee 600,000 tan.
Waqtigan xaadirka ah, waxaa jira in ka badan 40 shirkadood oo leh awoodda wax soo saarka graphite electrode ka badan 10,000 tan ee Shiinaha, iyada oo wadarta wax soo saarka ee ku saabsan 1.1 milyan oo tan. Si kastaba ha ahaatee, saamaynta ay ku leeyihiin kormeerayaasha ilaalinta deegaanka sanadkan, shirkadaha wax soo saarka graphite electrode ee gobollada Hebei, Shandong iyo Henan ayaa ku jira xaalad wax soo saar xaddidan iyo hakinta wax soo saarka, iyo wax soo saarka graphite electrode sanadlaha ah waxaa lagu qiyaasaa in ay ku saabsan 500,000 tan.
"Farqiga u dhexeeya suuqa ee qiyaastii 100,000 oo tan laguma xallin karo shirkadaha kordhinaya awoodda wax soo saarka." Ning Qingcai ayaa sheegay in wareegga wax soo saarka ee alaabta electrode graphite guud ahaan waa in ka badan laba ama saddex bilood, iyo wareegga stocking, ay adag tahay in la kordhiyo mugga ee muddada gaaban.
Shirkadaha Carbon waxay hoos u dhigeen wax soo saarkooda oo way xidhmeen, laakiin baahida shirkadaha birta ayaa sii kordhaya, taas oo horseedaysa in graphite electrode uu noqdo badeecad ciriiri ah oo suuqa ah, qiimihiisuna wuxuu ahaa mid kor u kacaya. Waqtigan xaadirka ah, qiimaha suuqa ayaa kordhay 2.5 jeer marka la barbardhigo bishii Janaayo ee sanadkan. Shirkadaha birta qaarkood waa inay hore u bixiyaan si ay alaabta u helaan.
Sida laga soo xigtay khubarada warshadaha, marka la barbar dhigo foornada qaraxa, birta foornada korantada ayaa aad u badbaadinaysa tamar, jawi saaxiibtinimo iyo kaarboon yar. Iyadoo Shiinuhu uu galo wareegga qiimo-dhaca qashinka, birta foornada korontada ayaa gaari doonta horumar weyn. Waxaa lagu qiyaasaa in saamiga ay ku leedahay wadarta wax soo saarka birta la filayo inuu ka kordho 6% 2016 ilaa 30% sanadka 2030, iyo baahida loo qabo electrodes garaafyada ayaa weli ah mid weyn mustaqbalka.
Kor u kaca qiimaha alaabta ceeriin ee korka ah ma hoos u dhacdo
Kordhinta qiimaha korantada graphite ayaa si dhakhso ah loogu gudbiyay kor u kaca silsiladda warshadaha. Tan iyo bilowgii sanadkan, qiimaha alaabta ceeriin ee waaweyn ee wax-soo-saarka kaarboonka, sida kookaha batroolka, garoonka daamurka dhuxusha, kookaha calcined iyo kookaha irbadda, ayaa si joogto ah u kacay, iyadoo celcelis ahaan kor u kacay 100%.
Madaxa qaybta wax iibsiga ayaa ku tilmaamay mid "kor u kacaysa". Sida laga soo xigtay masuulka, iyada oo ku saleysan xoojinta suuqa ka hor, shirkaddu waxay qaaday tallaabooyin ay ka mid yihiin wax ku iibsashada qiimo jaban iyo kordhinta alaabada si ay ula qabsadaan qiimaha korodhka iyo hubinta wax soo saarka, laakiin kor u kaca alaabta ceeriin ayaa ah. aad uga fog rajada.
Waxaa ka mid ah alaabta ceyriinka ah ee kor u kaca, coke cirbadda, oo ah alaabta ugu muhiimsan ee graphite electrode, ayaa leh qiimaha ugu weyn ee korodhka, iyadoo qiimaha ugu sarreeya uu kor u kacay 67% hal maalin gudaheed iyo in ka badan 300% nus sano. Waxaa la og yahay in kookaha irbadda ay ka dhigan tahay in ka badan 70% wadarta qiimaha graphite electrode, iyo alaabta ceeriin ee graphite koronto ultra-sare si buuxda u ka kooban yahay coke irbad, kaas oo cuna 1.05 tan per ton of graphite awood ultra-sare ah. electrode.
Irbada coke sidoo kale waxaa loo isticmaali karaa baytariyada lithium, tamarta nukliyeerka, hawada hawada iyo meelo kale. Waa badeeco aad u yar oo gudaha iyo dibadda ah, waxaana inteeda badan ay ku xiran tahay badeecadaha laga keeno Shiinaha, qiimihiisuna weli waa mid sarreeya. Si loo hubiyo wax soo saarka, shirkadaha garaafyada elektiroonigga ah ayaa midba midka kale kor u qaaday, taas oo keentay korodhka joogtada ah ee qiimaha kookaha irbadda.
Waxaa la fahamsan yahay in ay jiraan shirkado yar oo soo saara kookaha cirbadda ee Shiinaha, dadka warshaduhuna waxay aaminsan yihiin in korodhka qiimaha uu u muuqdo codka caadiga ah. Inkasta oo faa'iidada qaar ka mid ah soosaarayaasha alaabta ceeriin ay si weyn u horumareen, khataraha suuqa iyo kharashyada hawlgalka ee shirkadaha kaarboonka ee hoose ayaa sii kordhaya.
