Kwisiqingatha sokuqala sika-2021, imarike ye-graphite electrode iya kuqhubeka nokunyuka.Ukususela ekupheleni kukaJuni, imarike yasekhaya yasekhaya ye-φ300-φ500 i-electrode ye-graphite yamandla aqhelekileyo yacatshulwa kwi-16000-17500 yuan / ton, ngokunyuka okunyukayo kwe-6000-7000 yuan / ton;φ300-φ500 phezulu Ixabiso lemarike eliqhelekileyo le-electrode yegraphite yamandla yi-18000-12000 yuan/toni, ngokunyuka okunyukayo kwe-7000-8000 yuan/toni.
Ngokophando, ukunyuka kwee-electrode zegraphite ikakhulu kunemiba ilandelayo:
Okokuqala, ichaphazeleka ngokunyuka okuqhubekayo kwamaxabiso ezinto eziphathekayo;
Okwesibini, kwi-Inner Mongolia, eGansu nakweminye imimandla, kwakukho ukunqunyulwa kwamandla ngo-Matshi, kwaye inkqubo ye-graphitization yayilinganiselwe.Abavelisi abaninzi banokuguqukela kuphela kwi-Shanxi nakweminye imimandla ukuze kuqhutywe.Imveliso yezinye iifektri ze-electrode ezifuna i-graphitization foundry yathotywa ngenxa yoko.Ukunikezelwa kwe-UHP550mm kunye neenkcazo ezingaphantsi zisaqinile, ixabiso liqinile, ukunyuka kubonakala ngokucacileyo, kwaye i-electrode ye-graphite eqhelekileyo kunye nephezulu ilandela ukunyuka;
Okwesithathu, abavelisi be-electrode be-graphite abaqhelekileyo abanalo uluhlu lwaneleyo, kwaye ii-odolo zibekwe kude kube phakathi ukuya ekupheleni kukaMeyi.
Kwimarike:
Ngokwengxelo evela kwabanye abavelisi be-electrode, kwixesha elidlulileyo, ngexesha loMthendeleko weNtwasahlobo okanye ngelo xesha, babeza kuthenga inani elithile lezinto eziluhlaza.Nangona kunjalo, ngo-2020, ngenxa yokunyuka okuqhubekayo kwexabiso lezinto eziluhlaza ngoDisemba, abavelisi ubukhulu becala balinda kwaye babone.Ke ngoko, uluhlu lwezinto ezibonakalayo ngo-2021 ayanelanga, kwaye abanye abavelisi Ukusetyenziswa kuya kuhlala kude kube nguMthendeleko weNtwasahlobo.Ukusukela ekuqaleni kuka-2021, ngenxa yezehlo zempilo yoluntu, uninzi lweenkampani ezisebenza kunye neziyeleleneyo, ezizezona zisesona siseko sikhulu semveliso yegraphite electrode machining elizweni, ziye zanqumamisa umsebenzi kunye nemveliso, kwaye impembelelo yokuvalwa kwendlela ibangele ubunzima kwezothutho.
Kwangaxeshanye, ukulawulwa kokusebenza kakuhle kwamandla amabini kwi-Inner Mongolia kunye nokunqunyulwa kwamandla eGansu nakweminye imimandla ukusuka ngoJanuwari ukuya kuMatshi kubangele iibhotile ezinzulu kwinkqubo yegraphitization yegraphite electrode.Kude kube malunga phakathi ku-Epreli, i-graphitization yendawo yaqala ukuphuculwa kancinci, kodwa umthamo wemveliso wakhululwa.Kuphela yi-50-70%.Njengoko sonke sisazi, i-Inner Mongolia liziko le-graphitization e-China.Ulawulo oluntlu-mbini lunempembelelo ethile ekukhutshweni kamva kwabenzi be-semi-process yegraphite electrode.Ukuchatshazelwa lugcino olusembindini lwemathiriyeli ekrwada kunye neendleko eziphezulu zokuhanjiswa ngo-Epreli, abavelisi be-electrode abaqhelekileyo banyuse amaxabiso emveliso yabo ngokuphindwe kabini ekuqaleni naphakathi ukuya ekupheleni kuka-Epreli, kunye nabenzi be-echelon yesithathu bagcina kancinci ngasekupheleni kuka-Epreli.Nangona awona maxabiso entengiselwano ebeselungile, Kodwa umsantsa ucuthekile.
Kuze kube "amaconsi amane alandelelanayo" e-Daqing petroleum coke, kwakukho ingxoxo eshushu kwiimarike, kwaye ingqondo yomntu wonke yaqala ukutshintsha kancinci.Abanye abavelisi be-electrode begraphite bafumanise ukuba amaxabiso ee-electrode zegraphite zabavelisi ngabanye aye ehla kancinci ngexesha lokubhida phakathi ukuya ekupheleni kukaMeyi.Nangona kunjalo, ngenxa yokuba ixabiso le-coke yenaliti yasekhaya lihlala lizinzile kwaye ukunikezelwa kwe-coke yaphesheya kuya kuba nzima kwixesha elizayo, abaninzi abenzi be-electrode be-graphite bakholelwa ukuba ixabiso le-electrode kamva liya kuhlala linjalo okanye liguquguquke kancinane.Emva kwayo yonke loo nto, izinto ezithengiswa ngexabiso eliphezulu zisekho kumgca wemveliso.Ukuveliswa, i-electrodes iya kuchaphazeleka ngeendleko kwixesha elizayo elikufutshane, akunakwenzeka ukuba amaxabiso awele.
