Kusukela ngo-2018 kuya ku-2022, amandla okubambezeleka kwamayunithi okupheka e-China ahlangabezane nenqubo yokukhula kuqala bese ehla, kanye namandla okubambezeleka kwamayunithi okupheka e-China abonise umkhuba wokukhula unyaka nonyaka ngaphambi kuka-2019. Ekupheleni kuka-2022, i amandla okubambezeleka kwamayunithi okupheka eShayina ayengamathani ayizigidi eziyi-149.15, kanti amanye amayunithi adlulisiwe aqala ukusebenza. Ngomhla ziyisi-6 kuNovemba, ukuphakelwa okuyinhloko kwamathani ayizigidi ezi-2/ngonyaka okubambezelekile kwe-Shenghong Refining and Chemical Integration Project (Shenghong Refining and Chemical) kwaphumelela futhi kwakhiqiza imikhiqizo efanelekile. Amandla eyunithi yokupheka ebambezelekile e-East China aqhubeka nokukhula.
Sekukonke ukusetshenziswa kwe-coke ye-petroleum yasekhaya kubonise ukuthambekela okukhuphukayo kusukela ngo-2018 kuya ku-2022, futhi inani eliphelele lokusetshenziswa kwe-coke ye-petroleum lasekhaya lahlala lingaphezu kwamathani ayizigidi ezingu-40 kusukela ngo-2021 kuya ku-2022. Kodwa-ke, ngo-2022, amanye amabhizinisi angezansi ayeqaphile ekuthengeni ngenxa yomthelela walolu bhubhane, futhi izinga lokukhula lokusetshenziswa kwe-petroleum coke lehla kancane lafinyelela cishe ku-0.7%.
Emkhakheni we-anode ephekwe ngaphambilini, kube nokuthambekela okwandayo eminyakeni emihlanu edlule. Ngakolunye uhlangothi, isidingo sasekhaya senyukile, futhi ngakolunye uhlangothi, ukuthunyelwa kwe-anode ephekwe ngaphambili kubonise umkhuba okhulayo. Emkhakheni we-graphite electrode, ukuguqulwa kwe-supply-side kusukela ngo-2018 kuya ku-2019 kusafudumele, futhi isidingo se-graphite electrode sihle. Kodwa-ke, ngokuncipha kwemakethe yensimbi, inzuzo ye-electric arc furnace steelmaking iyanyamalala, isidingo se-graphite electrode siyancipha kakhulu. Emkhakheni we-ejenti ye-carburizing, ukusetshenziswa kwe-petroleum coke bekulokhu kuzinzile eminyakeni yamuva, kodwa ngo-2022, ukusetshenziswa kwe-petroleum coke kuzokhuphuka kakhulu ngenxa yokwanda kwe-ejenti ye-carburizing njengomkhiqizo we-graphitization. Isidingo se-petroleum coke endaweni kaphethiloli sincike kakhulu emehlukweni wentengo phakathi kwamalahle ne-petroleum, ngakho ishintshashintsha kakhulu. Ngo-2022, intengo ye-petroleum coke izohlala iphezulu, futhi inzuzo yentengo yamalahle izokhuphuka, ngakho ukusetshenziswa kwe-petroleum coke kuzokwehla. Imakethe ye-silicon metal ne-silicon carbide eminyakeni emibili edlule inhle, futhi ukusetshenziswa kwayo yonke kuyanda, kodwa ngo-2022, ibuthakathaka kunonyaka odlule, futhi ukusetshenziswa kwe-petroleum coke kwehla kancane. Umkhakha wezinto ze-anode, osekelwa inqubomgomo kazwelonke, uye wanda unyaka nonyaka eminyakeni yamuva. Mayelana nokuthunyelwa kwamanye amazwe i-char calcined, ngokwenyuka kwesidingo sasekhaya kanye nenzuzo yasekhaya ephezulu uma kuqhathaniswa, ibhizinisi lokuthekelisa lokuthekelisa le-calcined char lehlisiwe.
Isibikezelo semakethe esizayo:
Kusukela ngo-2023, isidingo semboni yasekhaya ye-petroleum coke singase sikhuphuke. Ngokukhula noma ukuqedwa komthamo othile wokucwenga, eminyakeni emihlanu ezayo, umthamo wokukhiqiza waminyaka yonke ka-2024 uzophakama bese wehlela esimweni esizinzile, futhi umthamo wokukhiqiza wonyaka ka-2027 kulindeleke ukuthi ufinyelele amathani ayizigidi eziyi-149.6 ngonyaka. Ngesikhathi esifanayo, ngokwanda ngokushesha komthamo wokukhiqiza wezinto ze-anode nezinye izimboni, isidingo sifinyelele ukuphakama okungakaze kube khona. Kulindeleke ukuthi isidingo sasekhaya semboni ye-petroleum coke sigcine ukuguquguquka kwaminyaka yonke kwamathani ayizigidi ezingama-41 eminyakeni emihlanu ezayo.
Mayelana nemakethe yokuphela kwesidingo, ukuhweba okuphelele kuhle, ukusetshenziswa kwezinto ze-anode kanye nensimu ye-graphitization kuyaqhubeka nokukhula, isidingo sensimbi semakethe ye-aluminium carbon sinamandla, ingxenye ye-coke engenisiwe ingena emakethe ye-carbon ukuze igcwalise ukunikezwa, futhi imakethe ye-petroleum coke isethula isimo somdlalo wesidingo sokuhlinzeka.
