Izindawo ezisetshenziswa kakhulu ezansi nomfula zemikhiqizo ye-coke yaseShayina ye-petroleum zisagxile ku-anode ebhakwe ngaphambili, uphethiloli, i-carbonator, i-silicon (okuhlanganisa i-silicon metal ne-silicon carbide) kanye ne-graphite electrode, okuphakathi kwayo ukusetshenziswa kwensimu ye-anode ebhakwe ngaphambilini ihlanganisa phezulu.Eminyakeni yakamuva, inzuzo yokukhiqizwa kwemakethe ye-electrolytic aluminium kanye nemikhiqizo ye-silicon iyaqhubeka nokuba phezulu, futhi amabhizinisi aphansi anentshiseko ngokuthenga nokukhiqiza, osekuyimbangela eyinhloko yokukhula kokusetshenziswa kwe-petroleum coke.
Ishadi lesakhiwo se-Chinese petroleum coke ukusetshenziswa ngo-2021
Ngo-2021, inkambu yokusetshenziswa kwe-coke ye-petroleum yaseShayina esezansi nomfula iseyi-anode ephekwe ngaphambili, i-fuel, i-silicon, i-carbonizer, i-graphite electrode nezinto ze-anode.
Kuwo wonke unyaka, umkhawulo wenzuzo yakho kokubili i-electrolytic aluminium, i-silicon metal ne-silicon carbide ifinyelele izinga eliphezulu, futhi amabhizinisi akhuthazeke kakhulu ukuba aqale ukwakha. Kodwa-ke, njengemboni esetshenziswa kakhulu amandla, ukukhiqizwa okuphelele kuthintwa kakhulu ukukhawulelwa kwamandla. Nakuba isidingo singeke sikhishwe ngokuphelele, isidingo se-petroleum coke sisakhula.
Mayelana nophethiloli, ngaphansi kwesizinda sokushoda kwamalahle, izindawo zokuhluza zandisa ukuzisebenzisa, zandisa umthamo wokuthenga kanye nesidingo esihle jikelele; Ngo-2021, izitshalo zengilazi zinenzuzo enhle, izinga eliphezulu lokusebenzisa kanye nesidingo esihle se-petroleum coke.Isidingo esihle sezinto ezingezinhle zama-electrode siphinde sigqugquzele ukukhiqizwa kwama-ejenti athuthukisa i-carbon.Isidingo sama-silicon electrode SILUNGILE, kodwa isidingo sama-electrode ensimbi jikelele.
Ishadi lasekhaya lentengo ye-coke ebaliwe ngo-2021
Engxenyeni yokuqala ka-2021, intengo ye-coke yokubala ngesulfure ephansi yasekhaya ibonise inkambiso yokukhuphuka kuqala bese yehla. Engxenyeni yesibili yonyaka, ukusekelwa kokuphela kwesidingo bekuzinzile, futhi intengo ye-coke yokubala iqhubekile nokukhuphuka.Ngokwesekwa amanani entengo yezinto ezingavuthiwe, amanani e-coke e-calcined akhuphuka kakhulu, futhi intengo yokuthengiselana ngekota yokuqala yenyuka ngama-yuan angama-2,850. / ton.Engxenyeni yesibili yonyaka, isidingo esiphansi somfula esithintwe ukukhawulelwa kwamandla kanye nenqubomgomo yokulawula kabili saphenduka saba buthaka, kodwa imakethe yezinto ezingezinhle ze-electrode yabonisa ukwesekwa okuhle, ikhwalithi ephezulu kanye nenani eliphansi le-coke yesibabule yaqhubeka nokukhuphuka, eliphansi. intengo ye-coke yokubala isulfure yenyuka ngokufanele, futhi intengo ye-coke yokubala ngekota yesine ikhuphuke yafinyelela phezulu ngonyaka.
Ngo-2021, intengo yasekhaya ye-coke kawoyela wesulfure esezingeni eliphakeme ngokuyisisekelo yakhombisa ukwenyuka okuhlangene, futhi intengo ye-terminal electrolytic aluminium yenyuka yafinyelela phezulu emlandweni kulo nyaka. Intshiseko yemakethe ye-aluminiyamu yekhabhoni yokungena emakethe yayiphezulu, futhi ngaphansi kokusekelwa kokuphela kwesidingo, intengo ye-coke eyenziwe ngesulphur ephakathi nendawo igcine inkambiso ekhuphukayo. Ekuqaleni kukaNovemba, ngenxa yokwehla ngezikhathi ezithile kwentengo ye-petroleum coke. , intengo ye-coke ebaliwe yehle kancane, kodwa intengo iyonke beyisephezulu kunesikhathi esifanayo ngonyaka odlule.
Ishadi lentengo le-coke ye-sulphur ephakathi nendawo kanye ne-anode ebhakwe ngaphambilini ngo-2021
Ngo-2021, isekelwa ukukhuphuka okubukhali kwemakethe yetheminali, intengo ye-anode ephekwe ngaphambilini yakhuphuka yafika ezingeni eliphezulu. Isilinganiso senani saminyaka yonke se-anode ebhakwe ngaphambilini sasingu-4,293 yuan/ton, futhi intengo emaphakathi yonyaka ikhuphuke ngo-1,523 yuan/ton noma ngo-54.98% uma iqhathaniswa neyango-2020.
Engxenyeni yokuqala yonyaka, amabhizinisi asekhaya ase-anode abhakwe ngaphambilini aqala kancane, athintwa kakhulu amanani entengo yezinto ezingavuthiwe. intengo iyonke beyisalokhu iphezulu, futhi isidingo se-coke yesibabule esimaphakathi besizinzile, kanye nomthelela wentengo ye-coke yesibabule esimaphakathi entengo ye-anode ebhakwe ngaphambilini uye wathuthukiswa. ukukhululwa kwamandla amasha okukhiqiza amabhizinisi e-aluminium kwakha ukusekelwa okuphumelelayo kokuthunyelwa kwemakethe ye-anode ebhakwe ngaphambili.NgoDisemba, amanani entengo ye-anode ephekwe ngaphambilini ehla ngenxa yokwehla kwamanani ezinto ezingavuthiwe, kodwa unyaka wonke, intengo ephakeme kakhulu kunaleyo ngesikhathi esifanayo ngonyaka odlule.
Ishadi lentengo yasekhaya ye-carbonizer ngo-2021
Ngo-2021, ukuhweba kwemakethe ye-carbon agent yasekhaya kulungile. Iqhutshwa imakethe yezinto zokusetshenziswa kanye nezinto ze-cathode, intengo ye-carbon agent yashintshashintsha engxenyeni yokuqala yonyaka. Engxenyeni yesibili yonyaka, iqale ukukhuphuka kakhulu ngentengo yezinto ezingavuthiwe, futhi intengo ye-carbon agent nayo yakhombisa ukukhuphuka okuguquguqukayo.
Kuwo wonke unyaka, intengo ye-coke carbon enyusa i-ejenti ekhuphukayo iholela ekushodeleni kwezinsiza ze-petroleum coke zasekhaya ezindaweni zokuhluzwa ezifuywayo (ukugcinwa endaweni eyodwa kwemithombo ye-coke e-calcined namalahle kuqinile). , abanye abakhiqizi be-graphite carbonizer ngokuyinhloko bathola izindleko zokucubungula isizukulwane sezinto ezingezinhle ze-electrode, okuholela ekwandeni kwe-Graphite carbonizer kuncane kakhulu kunaleyo yezinto zokusetshenziswa. Ezingxenyeni ezintathu zokuqala, intengo ibisebenza ngokuzinzile, futhi ikota yesine yaqala ukufuna ukushayela intengo.
Ishadi elilinganayo le-thermal thermal coke ne-petroleum coke ngo-2021
Ezingxenyeni ezintathu zokuqala zonyaka wezi-2021, umnotho omkhulu waseShayina uqhubekile nokusimama kancane kancane, kanti isamba esisetshenziswa ugesi sinyuke ngo-12.9% unyaka nonyaka. Isidingo sikagesi sikhule ngokushesha, nokukhishwa kabi kwamandla kagesi, ukukhiqizwa kwamandla ashisayo kukhuphuke ngo-11.9% ezinyangeni eziyi-9 zokuqala unyaka nonyaka, futhi isidingo samalahle esishisayo sakhula ngokushesha, okungamandla amakhulu aqhuba ukukhula kokusetshenziswa kwamalahle. Ngaphansi kwethonya lekhabhoni. ukunciphisa ukungcola, "ukulawula kabili ukusetshenziswa kwamandla" kanye nokukhawulela ukuthuthukiswa okungaboni kahle kwamaphrojekthi "amabili aphezulu", ukuqina kokukhiqizwa kwensimbi, izimboni zokwakha kanye nezimboni zamakhemikhali kwehla kancane kancane, izinga lokukhula kokukhiqizwa kwe-pig iron, coke, usimende kanye eminye imikhiqizo ehlobene nayo yehla, futhi ukusetshenziswa kwamalahle embonini yensimbi nezinto zokwakha kwehla ngokufanele.Ngokujwayelekile, ukusetshenziswa kwamalahle kweChina ezingxenyeni ezintathu zokuqala zokusetshenziswa kwamalahle kwakhula ngokushesha unyaka nonyaka, futhi izinga lokukhula lehla kancane kancane.Kusukela ekuqaleni kulo nyaka, ukunikezwa kwemakethe yamalahle kanye nesidingo ngokuvamile kuqinile, inani lamalahle kusixhumanisi ngasinye liphansi, futhi amanani ezimakethe zamalahle aphakeme.Ngaphansi kokusekelwa kwamanani aphezulu emakethe yamalahle, ukuthunyelwa kwemakethe kaphethiloli we-coke wesulphur yasekhaya kanye nephuma kwamanye amazwe. kwakha ukudonsa okuhle, ukusekela intengo ye-oil coke transaction yakhuphuka yafika ezingeni eliphezulu.Engxenyeni yesine, njengoba umbuso waqala ukulawula nokungenelela emakethe yamalahle, amanani amalahle ehla kakhulu, ukuthunyelwa kwemakethe ye-coke ephezulu yesibabule. kwehle ijubane, futhi ukungeniswa echwebeni kwe-coke kanye namanani kawoyela wasekhaya ehla ngokufanele.
Sekukonke, ngo-2021, umdlandla wokufuna ukuqeda ukuthengwa kwempahla muhle, futhi amadivayisi amasha okukhiqiza aphansi aqalisiwe. Nakuba isidingo sibuthakathaka kancane ngaphansi kwethonya lokulawula kabili, sisakha ukusekelwa okuqinile kwemakethe kawoyela ne-coke, futhi intengo ye-coke iyaqhubeka nokugcina ukusebenza okuphezulu. igxile emkhakheni we-anode ephekwe ngaphambilini ne-electrolytic aluminium. Imakethe ye-aluminium carbon iyaqhubeka nokuhwebelana kahle, intengo yemakethe yokugcina iphezulu, umthwalo oqalayo wamabhizinisi we-electrolytic aluminium uphezulu, futhi isidingo se-petroleum coke singase siqhubeke sikhuphuka.
