Kwisiqingatha sokuqala se-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, kunye nokunyuka 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 ikakhulu balinda kwaye babone. Ke ngoko, uluhlu lwezinto ezibonakalayo ngo-2021 alwanelanga, kwaye abanye abavelisi Ukusetyenziswa kuya kuhlala kude kube nguMthendeleko waseNtwasahlobo. Ukusukela ekuqaleni kuka-2021, ngenxa yezehlo zempilo yoluntu, uninzi lweenkampani ezisebenza kunye neziyeleleneyo, eziyeyona siseko sikhulu semveliso yomatshini we-graphite electrode kweli lizwe, 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. Kuze kube malunga no-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 kulondolozo olusembindini lwezixhobo ezikrwada kunye neendleko eziphezulu zokuhanjiswa ngo-Epreli, abavelisi be-electrode abaqhelekileyo banyuse amaxabiso emveliso yabo ngokuphindwe kabini ekuqaleni naphakathi ukuya ekupheleni kuka-Epreli, kwaye abavelisi 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 eninzi eshushu kwiimarike, kwaye ingqondo yomntu wonke yaqala ukutshintsha kancinci. Abanye abavelisi be-electrode begraphite bafumanise ukuba amaxabiso ee-electrode zegraphite zabavelisi ngabanye ebehle 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 kwiindleko kwixesha elizayo elisondeleyo, akunakwenzeka ukuba amaxabiso awele.
