"Qiimaynta tamarta" ayaa ahayd mawduuc aad u kulul Shiinaha tan iyo Sebtembar.Sababta "qeybsiga tamarta" waa horumarinta yoolka "dhexdhexaadnimada kaarboonka" iyo xakamaynta isticmaalka tamarta.Intaa waxaa dheer, tan iyo bilowgii sanadkan, waxaa jira warar kala duwan oo qiimaha alaabta ceeriin kiimikaad soo baxay midba midka kale, oo ay ku jiraan graphite electrode, oo ah walxo aad muhiim u ah warshadaha birta, ayaa helay dareenka yar ee suuqa sanadkan, iyo birta ah. warshadaha iyo dhexdhexaadnimada kaarboonka.
Silsilad warshadeed: inta badan waxaa loo isticmaalaa wax soo saarka birta
Graphite electrode waa nooc ka mid ah qalabka graphite iska caabin heerkulka sare ah, graphite electrode samayn kartaa hadda iyo koronto, si ay u dhalaali birta qashinka ee foornada qaraxa ama alaabta kale ee cayriin si ay u soo saaraan birta iyo alaabta kale ee biraha, inta badan loo isticmaalo wax soo saarka birta. .Electrode graphite waa nooc ka mid ah walxaha leh iska caabin hoose iyo iska caabin kulka kulaylka foornada arc koronto.Tilmaamaha ugu muhiimsan ee wax soo saarka graphite electrode waa wareegga wax soo saarka dheer (sida caadiga ah waa saddex ilaa shan bilood), isticmaalka awoodda sare iyo habka wax soo saarka adag.
Xaaladda silsiladda warshadaha ee electrode graphite:
silsiladda Graphite electrode silsilad kor alaabta ceeriin inta badan loogu talagalay coke batroolka, coke irbadda, saamiga alaabta ceeriin xisaab graphite electrode qiimaha waa ka weyn yahay, xisaabiyaa in ka badan 65%, ay sabab u tahay Shiinaha ee wax soo saarka coke technology iyo technology qaraabo Japan iyo kuwa kale wadamada wali waxaa ka jira farqi weyn, tayada coke coke ee gudaha waa adag tahay in la hubiyo, sidaa darteed ku tiirsanaanta Shiinaha ee soo dejinta ee ku tiirsanaanta kookaha tayada sare leh ayaa wali aad u sareysa, 2018, wadarta sahayda coke coke ee Shiinaha waxay ahayd 418,000 tan, kuwaas oo 218,000 oo tan ay ahaayeen dibadda laga keeno, oo ka dhigan in ka badan 50%.Codsiga ugu weyn ee korantada graphite-ka ayaa ku jira eAF birta samaynta.
Electrode graphite waxaa inta badan loo isticmaalaa birta iyo birta dhalaalaysa.Horumarinta warshadaha graphite electrode ee Shiinaha ayaa asal ahaan la jaan qaadaya casriyeynta warshadaha birta iyo birta ee Shiinaha.Shiinuhu graphite electrode waxa uu bilaabmay 1950kii.Warburg Securities ayaa u qaybisay horumarinta electrode graphite ee Shiinaha saddex marxaladood:
1. Horumarinta bilaabay 1995 - wax soo saarka ballaaran ee 2011;
2. Kala duwanaanshaha ganacsigu wuu sii xoogaystay 2013 - dhaqaaluhu aad buu u fiicnaaday 2017;
3. 2018 waxa uu ku socdaa wado hoos u dhac -dagaallada qiimaha ayaa ka dilaacay 2019.
Sahayda iyo baahida: Baahida foornada korontada ee birta ayaa xisaabisa inta badan
Marka la eego wax-soo-saarka iyo isticmaalka, marka loo eego falanqaynta dhaxan Sullivan, wax-soo-saarka electrodes-ka graphite ee Shiinaha ayaa hoos uga dhacay 0.53 milyan tan 2015 ilaa 0.50 milyan oo tan 2016, taasoo muujinaysa isbeddel hoos u dhac ah.Sannadka 2020, masiibadani waxay saameyn xun ku yeelatay hawlgallada wax-soo-saareyaasha sababta oo ah xannibaadaha maaraynta ee saacadaha shaqada, carqaladaynta xoogga shaqada iyo isbeddellada hababka hawlgalka.
Natiijo ahaan, wax soo saarka Shiinaha ee electrodes graphite ayaa si aad ah hoos ugu dhacay.Waxa ay rajaynaysaa in wax soo saarku gaadho 1,142.6 kilotons sanadka 2025, oo leh qiyaas dhan 9.7% laga bilaabo 2020 ilaa 2025.
Markaa taasi waa wax soo saar, ka dibna isticmaal.Isticmaalka korantada Graphite ee Shiinaha ayaa bilaabay inuu kordho laga bilaabo 2016, isagoo gaadhay 0.59 milyan tan 2020, oo leh 10.3% laga bilaabo 2015 ilaa 2020. wax soo saarka electrode iyo isticmaalka.
Soo saarida elektiroonigga graphite waxay la socotaa tan birta EAF.Kobaca wax soo saarka birta EAF ayaa kaxayn doona baahida graphite electrode mustaqbalka.Shiinaha ayaa soo saaray 127.4 milyan tan oo bir ah oo bir ah iyo 742,100 tan oo koronto garaafyo ah sanadka 2019, sida laga soo xigtay Ururka Birta iyo Birta Adduunka iyo Ururka Warshadaha Kaarboon ee Shiinaha.Wax soo saarka iyo heerka kobaca ee graphite electrode ee Shiinaha ayaa si dhow ula xidhiidha wax soo saarka iyo heerka kobaca birta eAF ee Shiinaha.
2019 iyo 2020, guud ahaan baahida caalamiga ah ee birta eAF iyo birta aan EAF ahayn waa 1.376,800 tan iyo 1.472,300 ton siday u kala horreeyaan.Warburg Securities ayaa saadaaliyay in baahida guud ee caalamiga ah ay kor u kacdo shanta sano ee soo socota oo ay gaadho 2.104,400 tan sanadka 2025
Marka la barbar dhigo samaynta birta foornada qaraxa, samaynta birta foornada korontada waxay leedahay faa'iidooyin muuqda oo ku saabsan qiiqa kaarboonka.Marka la barbar dhigo samaynta birta birta ah, samaynta birta leh 1 tan oo birta qashinka ah waxay yarayn kartaa 1.6 tan oo ah qiiqa kaarboon laba ogsaydh iyo 3 tan oo qashinka adag ah.Cilmi-baarista dallaalka ee foornada korontada iyo birta foornada qarxa halkii tan ee saamiga qiiqa kaarboonka ee 0.5: 1.9 heerka.Cilmi-baarayaasha Brokerage waxay yiraahdeen, "horumarinta birta foornada korontada waa inay noqotaa isbeddelka guud."
Bishii Maajo, Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta ayaa soo saartay Ogeysiiska Dhaqangelinta Tallaabooyinka Bedelka Awoodda ee Warshadaha Birta iyo Birta, kaas oo si rasmi ah loo hirgeliyay Juun 1. Tallaabooyinka hirgelinta ee beddelka awoodda ayaa si weyn u kordhin doona saamiga beddelka birta iyo ballaarinta meelaha muhiimka ah ee ka hortagga iyo xakamaynta wasakhowga hawada.Machadyadu waxay aaminsan yihiin in habka cusub ee beddelka awoodda uu hoos u dhigi doono awoodda birta, xoojinta warshadaha birta si loo xalliyo awoodda xad-dhaafka ah.Isla mar ahaantaana, hirgelinta habka beddelka ee dib loo eegay ayaa dardargelin doona horumarinta eAF, iyo saamiga birta eAF si joogto ah ayaa loo kordhin doonaa.
Graphite electrode waa sheyga ugu muhiimsan ee foornada korontada, oo ay kicisay baahida foornada korontada, dalabkeeda ayaa la filayaa in ay sii korodho, electrode graphite waxaa saameeya qiimaha.
Isbeddellada qiimaha weyn: sifooyinka meertada
Laga soo bilaabo 2014 ilaa 2016, suuqa garaafyada elektiroonigga ah ee caalamiga ah ayaa hoos u dhacay sababtoo ah baahida hoose ee daciifka ah, iyo qiimaha graphite electrode ayaa ahaa mid hooseeya.In 2016 la soo saarayaasha electrode graphite awoodda line off ka hooseeya qiimaha wax soo saarka, Inventory bulshada in ay hooseeyo, 2017 siyaasadda dhamaadka baabi'inta foornada inta jeer ee DeTiaoGang, tiro badan oo birta qashinka galay foornada birta, warshadaha electrode graphite ee Shiinaha qeybtii labaad ee Baahida 2017 ayaa kor u kacday, sababtoo ah kororka baahida loo qabo coke cirbadaha graphite electrode coke ee qiimaha alaabta ceeriin ayaa si aad ah kor ugu kacay 2017, 2019, waxay na soo gaadhay $3,769.9 halkii ton, ilaa 5.7 jeer laga soo bilaabo 2016.
