Engxenyeni yokuqala ka-2022, intengo ye-anode e-calcined ne-pre-baked engezansi komfula iqhutshwa ukwanda okuqhubekayo kwentengo ye-coke kaphethiloli eluhlaza, kodwa kusukela engxenyeni yesibili yonyaka, ukuthambekela kwentengo ye-coke kaphethiloli kanye nomkhiqizo ongezansi kwaqala ukuhlukahluka kancane kancane…
Okokuqala, thatha intengo ye-3B petroleum coke eShandong njengesibonelo. Ezinyangeni ezinhlanu zokuqala zika-2022, ukunikezwa kwe-petroleum coke yasekhaya bekulokhu kuphansi. Intengo ye-3B petroleum coke ikhuphuke isuka ku-3000 yuan/ton ekuqaleni konyaka yaya ngaphezu kuka-5000 yuan/ton maphakathi no-Ephreli, futhi le ntengo yaqhubeka kuze kube sekupheleni kukaMeyi. Kamuva, njengoba ukunikezwa kwe-petroleum coke yasekhaya kwanda, intengo ye-petroleum coke yaqala ukwehla, ishintshashintsha phakathi kuka-4,800-5,000 yuan/ton kwaze kwaba sekuqaleni kuka-Okthoba. Kusukela ngasekupheleni kuka-Okthoba, ngakolunye uhlangothi, ukunikezwa kwe-petroleum coke yasekhaya kuhlale kuphezulu, kuhlangene nomthelela wobhubhane ekuthuthweni okuphezulu nangaphansi, intengo ye-petroleum coke ifinyelele ebangeni lokwehla okuqhubekayo.
Okwesibili, engxenyeni yokuqala yonyaka, intengo ye-calcined char iyanda kanye nentengo ye-petroleum coke eluhlaza, futhi ngokuyisisekelo igcina umkhuba okhuphuka kancane. Engxenyeni yesibili yonyaka, yize intengo yezinto zokusetshenziswa incipha, intengo ye-calcined char yehla kancane. Kodwa-ke, ngo-2022, kusekelwa isidingo se-grapittization engemihle, isidingo se-common calcined char sizokhula kakhulu, okuzodlala indima enkulu ekusekeleni isidingo semboni yonke ye-calcined char. Engxenyeni yesithathu, izinsiza ze-calcined char zasekhaya zazike zantuleka. Ngakho-ke, kusukela ngoSepthemba, umkhuba wentengo ye-calcined char kanye nentengo ye-petroleum coke ubonise umkhuba ohlukile ocacile. Kuze kube nguDisemba, lapho intengo ye-petroleum coke eluhlaza yehla ngama-yuan angaphezu kuka-1000/ton, ukwehla okukhulu kwezindleko kuholele ekwehleni okuncane kwentengo ye-calcined char. Kungabonakala ukuthi ukunikezwa kanye nesidingo semboni ye-calcined charring yasekhaya kusesesimeni esiqinile, futhi ukwesekwa kwentengo kusaqinile.
Ngemuva kwalokho, njengomkhiqizo othengiswa ngentengo yezinto zokusetshenziswa, ukuthambekela kwentengo ye-anode ebhakiwe kusengaphambili kumakota amathathu okuqala kuhambisana ngokuyisisekelo nokuthambekela kwentengo ye-coke kaphethiloli eluhlaza. Kodwa-ke, kukhona umehluko phakathi kwentengo nentengo ye-coke kaphethiloli kwikota yesine. Isizathu esiyinhloko ukuthi intengo ye-coke kaphethiloli ekuhlanzweni kwasekhaya iyashintshashintsha njalo futhi ukuzwela kwemakethe kuphakeme. Indlela yamanani ye-anode ebhakiwe kusengaphambili ifaka intengo ye-coke kaphethiloli eyinhloko njengesampula yokuqapha. Intengo ye-anode ebhakiwe kusengaphambili izinzile, okusekelwa ukuguquguquka kwentengo yemakethe okubambezeleka kwentengo ye-coke kaphethiloli eyinhloko kanye nokwenyuka okuqhubekayo kwentengo ye-tar yamalahle. Kumabhizinisi akhiqiza i-anode ebhakiwe kusengaphambili, inzuzo yawo ikhuliswe ngezinga elithile. NgoDisemba, umthelela wamanani e-coke kaphethiloli eluhlaza ngoNovemba wehla, amanani e-anode ebhakiwe kusengaphambili ehla kancane.
Ngokuvamile, umkhiqizo we-petroleum coke wasekhaya ubhekene nesimo sokuthengiswa ngokweqile, intengo iyancishiswa. Kodwa-ke, ukunikezwa kanye nesidingo semboni ye-calcined char kusabonisa ibhalansi eqinile, futhi intengo isasekela. I-anode ebhakiwe kusengaphambili njengemikhiqizo yamanani ezinto zokusetshenziswa, yize ukunikezwa kanye nesidingo samanje kucebile kancane, kodwa imakethe yezinto zokusetshenziswa isenayo amanani okusekela awazange ehle.
