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 Eminyakeni yamuva nje, inzuzo yokukhiqizwa kwemakethe ye-electrolytic aluminium kanye nemikhiqizo ye-silicon iyaqhubeka nokuba phezulu, futhi amabhizinisi aphansi anentshiseko yokuthenga nokukhiqiza, osekuyimbangela eyinhloko yokukhula kokusetshenziswa kwe-petroleum coke.
Ishadi lesakhiwo se-Chinese petroleum coke ukusetshenziswa ngo-2021
Ngo-2021, inkambu yokusetshenziswa ephansi komfula ye-coke ye-petroleum yaseShayina isabhakwa ngaphambilini i-anode, uphethiloli, 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 kukonke kuthintwa kakhulu ukukhawulelwa kwamandla.Nakuba isidingo singeke sikhishwe ngokuphelele, isidingo se-petroleum coke sisakhula.
Ngokuphathelene nophethiloli, ngaphansi kwesizinda sokushoda kwamalahle, izindawo zokuhluza zandisa ukuzisebenzisa, zandisa umthamo wokuthenga kanye nesidingo esihle jikelele;Ngo-2021, izitshalo zezingilazi 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 umkhuba wokukhuphuka kuqala bese wehla.Engxenyeni yesibili yonyaka, ukusekelwa kokuphela kwesidingo bekuzinzile, futhi intengo ye-coke yokubala iqhubekile nokukhuphuka.Ngokwesekelwa amanani entengo yezinto ezingavuthiwe, amanani e-coke e-calcined akhuphuka kakhulu, futhi intengo yokuthengiselana ngekota yokuqala yenyuka ngamayuan ayi-2,850. / ton.Engxenyeni yesibili yonyaka, isidingo esiphansi somfula esithintwe ukuvinjelwa kwamandla kanye nenqubomgomo yokulawula kabili saphenduka yaba buthakathaka, kodwa imakethe yempahla ye-electrode engalungile ibonise ukwesekwa okuhle, ikhwalithi ephezulu kanye nentengo ye-coke yesibabule ephansi iqhubekile nokukhuphuka, ephansi. intengo ye-coke yokubala isulfure yenyuka ngokufanele, futhi intengo ye-coke yokubala ngekota yesine ikhuphuke yafinyelela phezulu ngonyaka.
Ngo-2021, intengo ye-coke kawoyela wesulfure esezingeni eliphezulu yasekhaya yakhombisa ukwenyuka okukodwa, futhi intengo ye-terminal electrolytic aluminium yenyuka yafinyelela phezulu emlandweni kulo nyaka.Umdlandla wemakethe ye-aluminiyamu yekhabhoni yokungena emakethe wawuphezulu, futhi ngaphansi kokusekelwa kokuphela kwesidingo, intengo ye-coke enesulfure 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 sonyaka 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 aphekwe ngaphambilini aqala kancane, athintwa kakhulu amanani entengo yempahla eluhlaza. 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 e-anode abhakwe ngaphambili ehla ngenxa yokwehla kwamanani ezinto ezingavuthiwe, kodwa unyaka wonke, intengo ngaphezulu kakhulu kwalokho 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 ekushodeni kwezinsiza ze-petroleum coke zasekhaya ezindaweni zokuhluzwa ezifuywayo (ukugcinwa endaweni eyodwa kwemithombo ye-coke e-calcined namalahle kuqinile). , abanye abakhiqizi be-graphite carbonizer ikakhulukazi bathola izindleko zokucubungula isizukulwane sezinto ezingezinhle ze-electrode, okuholela ekwenyukeni kwe-Graphite carbonizer kuncane kakhulu kunaleyo yezinto zokusetshenziswa.Ezingxenyeni ezintathu zokuqala, intengo ibisebenza ngokuzinzile, futhi ikota yesine yaqala ukufuna ukushayela intengo.
Ishadi lenani 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, nokungabibikho kokukhishwa 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 yawa, 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 kokuphezuluukusekelwa kwentengo yemakethe yamalahle, ukuthunyelwa kwemakethe kaphethiloli we-coke enesulfure ephezulu yasekhaya kanye nephuma kwamanye amazwe kwakha ukudonsa okuhle, ukusekela intengo yokuthengiswa kwe-coke kawoyela yenyuka yafika ezingeni eliphezulu.Ngekota yesine, njengoba umbuso waqala ukulawula nokungenelela imakethe yamalahle, amanani entengo yamalahle ehla kakhulu, ukuthunyelwa kwemakethe ye-coke enesulfure ephezulu kwehla, kanye nokungeniswa echwebeni kwe-coke nezintengo zikawoyela wasekhaya zehla 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 ukusekela okuqinile kwemakethe kawoyela ne-coke, futhi intengo ye-coke iyaqhubeka nokugcina ukusebenza okuphezulu. kugxile emkhakheni we-anode ephekwe ngaphambili ne-electrolytic aluminium.Imakethe ye-aluminium carbon iyaqhubeka nokudayisa kahle, intengo yemakethe yokugcina iphezulu, umthwalo oqalayo wamabhizinisi we-electrolytic aluminium uphezulu, futhi isidingo se-petroleum coke singase siqhubeke sikhuphuka.
