Ukusukela ngo-2018 ukuya ku-2022, umthamo wokulibaziseka kweeyunithi zokuphekela e-China ufumene umkhwa wokunyuka kuqala kwaye wehla, kwaye umthamo wokulibaziseka kweeyunithi zokupheka e-China ubonise umkhwa wokunyuka unyaka nonyaka phambi ko-2019. Ekupheleni kuka-2022, i amandla okulibaziseka kweeyunithi zokuphekela eTshayina malunga ne-149.15 yezigidi zeetoni, kwaye ezinye iiyunithi ziye zagqithiselwa zaza zaqalisa ukusebenza. Ngomhla wesi-6 kuNovemba, ukondla okuphambili kwe-2 yezigidi zeetoni / ngonyaka kulibaziseke iyunithi yokupheka yeProjekthi yokuSungula kunye neProjekthi yoHlanganiso lweMichiza (i-Shenghong yokuSungula kunye neMichiza) iphumelele kwaye ivelise iimveliso ezifanelekileyo. Umthamo wokulibaziseka kweyunithi yokupheka e-East China uqhubeke usanda.
Ukusetyenziswa kwe-petroleum coke yasekhaya ngokubanzi kubonise ukunyuka ukusuka ku-2018 ukuya ku-2022, kwaye ukusetyenziswa kwe-petroleum coke yasekhaya iyonke yahlala ingaphezulu kwe-40 yezigidi zeetoni ukusuka ku-2021 ukuya ku-2022. Ngo-2021, imfuno ephantsi yomlambo inyuke kakhulu kwaye izinga lokukhula kokusetyenziswa liye lanyuka. Nangona kunjalo, ngo-2022, amanye amashishini asezantsi ayelumkile ekuthengeni ngenxa yempembelelo yobhubhane, kwaye izinga lokukhula lokusetyenziswa kwe-petroleum coke lehla kancinci ukuya malunga ne-0.7%.
Kwintsimi ye-anode ebhakiweyo ngaphambili, kukho ukunyuka okunyukayo kwiminyaka emihlanu edlulileyo. Ngakolunye uhlangothi, imfuno yasekhaya iye yanda, kwaye ngakolunye uhlangothi, ukuthunyelwa ngaphandle kwe-anode ebhakiweyo kwangaphambili kuye kwabonisa ukunyuka okunyukayo. Kwintsimi ye-graphite electrode, ukulungiswa kwecala lokubonelela ukusuka kwi-2018 ukuya kwi-2019 kuseshushu, kwaye imfuno ye-graphite electrode ilungile. Nangona kunjalo, ngokuncipha kwemarike yensimbi, inzuzo yombane we-arc i-steelmaking iyanyamalala, imfuno ye-graphite electrode iyancipha kakhulu. Kwintsimi ye-agent ye-carburizing, ukusetyenziswa kwe-petroleum coke kuzinzile kwiminyaka yamuva nje, kodwa ngo-2022, ukusetyenziswa kwe-petroleum coke kuya kunyuka kakhulu ngenxa yokwanda kwe-agent ye-carburizing njengemveliso ye-graphitization. Imfuno yepetroleum coke kwindawo yamafutha ikakhulu ixhomekeke kumahluko wexabiso phakathi kwamalahle kunye nepetroleum, ngoko ke iyaguquguquka kakhulu. Ngo-2022, ixabiso le-petroleum coke liya kuhlala liphezulu, kwaye inzuzo yexabiso lamalahle iya kunyuka, ngoko ukusetyenziswa kwe-petroleum coke kuya kuncipha. Imakethi ye-silicon yesinyithi kunye ne-silicon carbide kule minyaka mibini idlulileyo ilungile, kwaye ukusetyenziswa kukonke kuyanda, kodwa ngo-2022, ibuthathaka kunonyaka ophelileyo, kwaye ukusetyenziswa kwepetroleum coke kwehla kancinci. Intsimi yezinto ze-anode, exhaswa ngumgaqo-nkqubo kazwelonke, iye yanda unyaka nonyaka kwiminyaka yamuva. Ngokuphathelene nokuthumela ngaphandle i-calcined char, ngokunyuka kwemfuno yangaphakathi kunye nengeniso ephezulu yasekhaya, ishishini lokuthumela ngaphandle kwe-calcined char liye lancitshiswa.
Uqikelelo lwemarike yekamva:
Ukusukela ngo-2023, imfuno yoshishino lwepetroleum coke yasekhaya inokunyuka ngakumbi. Ngokunyuka okanye ukupheliswa komthamo othile wokucokisa, kwiminyaka emihlanu ezayo, umthamo wonyaka wemveliso ka-2024 uya kuphakama kwaye emva koko unciphe ukuya kwisimo esizinzileyo, kwaye umthamo wonyaka wemveliso we-2027 kulindeleke ukuba ufikelele kwi-149.6 yezigidi zeetoni / ngonyaka. Ngexesha elifanayo, kunye nokwandiswa ngokukhawuleza kwamandla okuvelisa izinto ze-anode kunye namanye amashishini, imfuno ifikelele ekuphakameni okungakaze kubonwe ngaphambili. Kulindeleke ukuba imfuno yangaphakathi yoshishino lwepetroleum coke igcine ukuguquguquka konyaka kweetoni ezizigidi ezingama-41 kule minyaka mihlanu izayo.
Ngokubhekiselele kwimarike yokuphela kwemfuno, ukurhweba ngokubanzi kulungile, ukusetyenziswa kwezinto ze-anode kunye nentsimi ye-graphitization iyaqhubeka nokunyuka, imfuno yensimbi ye-aluminium carbon market yomelele, inxalenye ye-coke ethunyelwa ngaphandle ingena kwimarike yekhabhoni ukuncedisa ukubonelela, kunye Imarike yepetroleum coke isabonisa imeko yomdlalo wemfuno yokubonelela.
