Ukukhuphuka kwengxenye yama-electrodes aphezulu we-graphite we-graphite amakhulu

1. Uchungechunge lwezimboni lwe-Graphite Electrode Endlwana

(1) Izimboni eziphezulu

Izinto zokusetshenziswa eziphambili ze-graphite electrodes yi-petroleum coke ne-witele coke, nge-coal tar pitch njengesengezo esikhulu. Izinto zokusetshenziswa ezivundwayo zengxenye enkulu yezindleko zokukhiqiza ze-graphite electrodes, accounting for 65%. Phakathi kwazo, uPetroleum Coke yinto ebalulekile eluhlaza yama-electrodes ajwayelekile we-graphite we-graphite, i-petroleum coke ne-witele coke yizinto eziphambili ze-graphite electrodes, futhi inaliti Coke impahla ephambili ye-graphite ye-graphite ye-graphi-high

I-Petroleum Coke ingukuphazamiseka kwamafutha, okuyizinhlayiyana eziqinile ezikhiqizwe ngokubambezeleka okubambezelekile usebenzisa i-petroleum slag njengento eluhlaza. Isetshenziswa kabanzi emikhakheni efana nama-electrodes we-graphite, i-electrolytic aluminium, ingilazi kanye ne-silicon yensimbi; I-Wistele Coke iyi-coke ephezulu yekhwalithi ephezulu enobunzima obuphansi kakhulu bokunwetshwa okushisayo kanye ne-braphitization elula. Inokuqhutshwa okuhle nokusebenza okushisayo, futhi kusetshenziswe ikakhulukazi kumandla we-graphite aphezulu namandla we-graphite aphezulu nezinto ezingezinhle ze-elektrodi zamabhethri e-lithium.

(2) Izimboni eziphansi

Ama-electrodes we-graphite asetshenziswa ikakhulukazi emasimini anjengokwenziwa kwensimbi, ukucwengwa kwe-silicon, kanye nokucwengiswa kwe-phosphorus ephuzi. Phakathi kwazo, ama-electrodes we-graphite we-Ultra-High-High asetshenziswa ku-Ultra-High Power Electric Funecking, ama-electrodes aphezulu we-graphite asetshenziswa ku-High-Power Electric Funec Macemacking, kanye nama-electrodes ajwayelekile we-graphite asetshenziswa esithandweni somlilo esijwayelekile sensimbi ensimbi, Ukucolisiswa, kucwengezela okuphuzi kwe-phosphorus, nokunye.

Ukubhema insimbi kuyinkambu yesicelo esemqoka yama-electrodes we-graphite, accounting cishe ama-80% wokusetshenziswa okuphelele kwama-electrodes we-graphite. Ukuthuthukiswa komkhakha wensimbi Swelting kuhlobene kakhulu nokuthuthukiswa kwe-Graphite Electrode Industry.

Ngo-2022, okukhishwa kwensimbi yomhlaba wonke kuzokwehla ngenxa yengxabano eqhubekayo phakathi kweRussia-Ukraine Ingxabano, ukulungiswa kwezinqubomgomo zezimali eYurophu nase-United States, ukukhuphuka okubukhali kwamanani entengo nakwezinye izinto. Ngokusho kwezibalo ze-Iron Iron ne-Association yensimbi, okukhishwa kwensimbi yomhlaba wonke kuzofinyelela amathani ayizigidi eziyizinkulungwane eziyi-1.8315 ngonyaka we-2022, ukwehla konyaka okungu-4,3%, futhi ukuphuma kwensimbi eyizigidi eziyizinkulungwane ezingama-1.013, unyaka- ukuncipha konyaka we-2.1%. Ngo-2023, ukukhiqizwa kwensimbi ephelele yomhlaba wonke kwakungamathani ayizigidi eziyizinkulungwane eziyi-1.8882, okwaqhubeka unyaka nonyaka. Inani eliphelele lensimbi ekhiqizwayo lamazwe nezifunda ezifakiwe eziteshini ze-Agency emhlabeni wonke kwakungamathani ayizigidi eziyizinkulungwane eziyi-1.8497, ukwehla okuncane kwe-0,1% unyaka nonyaka. Ukubheka izifunda ezahlukahlukene, ukukhiqizwa kwensimbi e-rude eYurophu, eNyakatho Melika, naseNingizimu Melika kwanciphisa unyaka, ngenkathi ukukhiqizwa kwezinye izifunda kwanda unyaka nonyaka; Mayelana namazwe, phakathi kwamazwe aphezulu akhiqizwa yinsimbi aphezulu emhlabeni, eJapan, eJalimane, uTürkiye naseBrazil abona ukukhula kweminyaka eminyaka, lapho amanye amazwe ebona ukukhula ngonyaka, lapho okuphuma khona ukukhula kufinyelele ku-11.8%. Ngokwemininingwane evela kwi-China Steel Association, ukukhiqizwa kwensimbi eluhlaza eChina ngo-2023 kwakungamathani ayizigidi eziyi-1019.08, unyaka ongashintshiwe; Kepha ngaphansi kokuholwa 'kwenhloso' yekhabhoni ebilisiwe, izwe elikhulisa amandla okulindisa ngogesi kwenqubo eqinile, elihambisana ne-International Development Trend.
