Ezona ndawo zisetyenzwayo ezantsi kweemveliso zepetroleum coke zaseTshayina zisagxile kwi-anode ebhakwe ngaphambili, i-fuel, i-carbonator, isilicon (kubandakanya i-silicon metal kunye ne-silicon carbide) kunye ne-graphite electrode, phakathi kwayo ukusetyenziswa kwentsimi ye-anode ebhakiweyo kuqala. Kwiminyaka yakutshanje, inzuzo yokuveliswa kweemarike ze-aluminium ye-electrolytic kunye neemveliso ze-silicon ziyaqhubeka ziphezulu, kwaye amashishini asezantsi anomdla wokuthenga kunye nokuveliswa kwemveliso, eye yaba yeyona nto iqhuba ukukhula kokusetyenziswa kwe-petroleum coke.
Itshathi yesakhiwo sokusetyenziswa kwepetroleum coke yaseTshayina ngo-2021
Ngo-2021, indawo esezantsi yokusetyenziswa kwe-petroleum coke yaseTshayina isabhakwa ngaphambili, i-anode, i-fuel, i-silicon, i-carbonizer, i-graphite electrode kunye ne-anode materials.
Kuwo wonke unyaka, umda wenzuzo yazo zombini i-aluminiyam ye-electrolytic, i-silicon yesinyithi kunye ne-silicon carbide ifikelele kwinqanaba eliphezulu, kwaye amashishini akhuthazeke kakhulu ukuba aqalise ukwakha. Nangona kunjalo, njengeshishini eliphezulu lokusetyenziswa kwamandla, imveliso iyonke ichaphazeleka kakhulu kukuthintelwa kwamandla. Nangona imfuno ayinakukhutshwa ngokupheleleyo, imfuno yepetroleum coke isakhula.
Ngokubhekiselele kumafutha, phantsi kwemvelaphi yokunqongophala kwamalahle, iindawo zokucoca zandisa ukuzisebenzisa, zandisa umthamo wokuthenga kunye nemfuno elungileyo yonke; Ngo-2021, izityalo zeglasi zinenzuzo entle, izinga eliphezulu lokusetyenziswa kunye nemfuno elungileyo yepetroleum coke.Imfuno elungileyo yemathiriyeli ye-electrode engalunganga ikwaqhuba ukuveliswa kweearhente zokuphucula ikhabhoni.Imfuno yee-electrode zesilicon ilungile, kodwa imfuno yeeelectrode zentsimbi yegraphite. jikelele.
Itshathi yexabiso le-coke yasekhaya ebaliwe ngo-2021
Kwisiqingatha sokuqala sika-2021, ixabiso le-coke le-coke ye-sulphur ephantsi yesulfure libonise umkhwa wokunyuka kuqala kwaye wehla. Kwisiqingatha sesibini sonyaka, inkxaso yokuphela kwemfuno yayizinzile, kwaye ixabiso le-coke lokubala liqhubekile nokunyuka. Ukuxhaswa ngamaxabiso ezinto ezibonakalayo, amaxabiso e-coke e-calcined aphakama ngokukhawuleza, kwaye ixabiso lokuthengiselana kwikota yokuqala linyuke nge-2,850 yuan. / ton.Kwisiqingatha sesibini sonyaka, imfuno esezantsi echatshazelwa kukuthintelwa kwamandla kunye nomgaqo-nkqubo wolawulo oluphindwe kabini yajika yaba buthathaka, kodwa imarike yezinto ze-electrode engalunganga ibonise inkxaso elungileyo, umgangatho ophezulu kunye nexabiso eliphantsi lecoke lesulfure liqhubekile nokunyuka, eliphantsi. Ixabiso lecoke yokubala isulfure linyuke ngokufanelekileyo, kwaye ixabiso lentengiselwano yecoke yokubala kwikota yesine linyuke laya kutsho phezulu ngonyaka.
Ngo-2021, ixabiso le-coke yeoli yesulfure yasekhaya ephakathi-phezulu ibonise ukunyuka okuhlangeneyo, kwaye ixabiso le-terminal electrolytic aluminium linyuke laya kwimbali ephezulu kulo nyaka. I-aluminiyam i-carbon market intando yokungena kwimarike yayiphezulu, kwaye phantsi kwenkxaso yokuphela kwemfuno, i-medium-sulfur calcined coke ixabiso ngokusisiseko ligcine ukunyuka. , ixabiso le-coke calcined lihlehlisiwe kancinci, kodwa ixabiso elipheleleyo lalisephezulu kunexesha elifanayo kunyaka ophelileyo.
Itshathi yexabiso lecoke yesulfure yasekhaya ephakathi kunye ne-anode ebhakwe kwangaphambili ngo-2021
Kwi-2021, exhaswa ngokunyuka okubukhali kweemarike ze-terminal, ixabiso le-anode ebhakiweyo ngaphambili liye laphakama kwinqanaba eliphezulu. Umndilili wexabiso lonyaka le-anode ebhakiweyo ngaphambili yayiyi-4,293 yuan / ton, kwaye ixabiso eliqhelekileyo lonyaka linyuke nge-1,523 yuan / itoni okanye i-54.98% xa kuthelekiswa naleyo ngo-2020.
Kwisiqingatha sokuqala sonyaka, amashishini e-anode aphekiweyo asekhaya aqala ngokuthe ngcembe, achaphazeleka kakhulu ngamaxabiso ezinto eziluhlaza. Kwisiqingatha sesibini sonyaka, ulwakhiwo lwehla ngenxa yempembelelo yolawulo oluphindwe kabini kunye nolwabiwo lwamandla kwezinye iingingqi, kodwa ixabiso lilonke lisahamba phezulu, kwaye imfuno yecoke yesulfure ephakathi yayizinzile, kwaye impembelelo yexabiso lecoke yesulfure ephakathi kwixabiso leanode ebhakiweyo yaphuculwa. Ukukhululwa kwamandla amatsha okuvelisa amashishini e-aluminium kwenza inkxaso esebenzayo yokuthunyelwa kwemarike ye-anode ebhakiwe ngaphambili.NgoDisemba, amaxabiso e-anode abhakiwe ngaphambili awela ngenxa yokuhla kwamaxabiso ezinto eziluhlaza, kodwa unyaka wonke, ixabiso phezulu kakhulu kunoko kwangexesha elifanayo kunyaka ophelileyo.
Itshathi yexabiso lekhabhoniza yasekhaya ngo-2021
Ngo-2021, intengiso ye-carbon agent yasekhaya ilungile. Ukuqhutyelwa yimarike yezinto eziluhlaza kunye nezinto ze-cathode, ixabiso le-carbon agent litshintshile kwisiqingatha sokuqala sonyaka. Kwisiqingatha sesibini sonyaka, yaqala ukunyuka kakhulu ngexabiso lezinto eziluhlaza, kwaye ixabiso le-carbon agent libonise ukunyuka okunyukayo.
Kuwo wonke unyaka, ixabiso le-coke ye-coke ekhulayo ye-agent ekhulayo ikhokelela ekunqongophelweni kwemithombo ye-petroleum ye-coke yasekhaya kwiindawo zokucoca zasekhaya (ukugcinwa okuphakathi kwe-coke e-calcined kunye nemithombo yamalahle iqinile). , abanye abavelisi bekhabhoniza yegraphite ikakhulu bafumana iindleko zokusetyenzwa kwemveliso yemathiriyeli ye-electrode engalunganga, okukhokelela ekunyukeni kweGraphite carbonizer ingaphantsi kakhulu kunemathiriyeli ekrwada. Kwiikota ezintathu zokuqala, ixabiso lalisebenza ngokusisiseko, kwaye ikota yesine yaqala ukufuna ukuqhuba ixabiso.
Itshathi yexabiso elilinganayo le-thermal thermal coke kunye nepetroleum coke ngo-2021
Kwiikota ezintathu zokuqala zowama-2021, uqoqosho olukhulu lwase-China luqhubekile nokusimama ngokuthe ngcembe, kwaye usetyenziso lombane lulonke lunyuke nge-12.9% ngonyaka. Imfuno yamandla yanda ngokukhawuleza, kunye nesiphumo esibi samandla ombane, ukuveliswa kwamandla obushushu kwanda nge-11.9% kwiinyanga ezili-9 zokuqala ngonyaka, kwaye imfuno yamalahle e-thermal yanda ngokukhawuleza, eyona nto iphambili eqhuba ukukhula kokusetyenziswa kwamalahle.Ngaphantsi kwempembelelo yekhabhoni. ukunciphisa ukukhutshwa, "ukulawula kabini ukusetyenziswa kwamandla" kunye nokunciphisa uphuhliso oluyimfama lweeprojekthi "ezimbini eziphezulu", ukuqina kwemveliso yentsimbi, izinto zokwakha kunye namashishini ekhemikhali yancipha ngokuthe ngcembe, izinga lokukhula kwemveliso yentsimbi yehagu, icoke, isamente kunye ezinye iimveliso ezihambelanayo zawa, kunye nokusetyenziswa kwamalahle kumashishini entsimbi kunye nezixhobo zokwakha kwawa ngokufanelekileyo.Ngokuphangaleleyo, ukusetyenziswa kwamalahle eChina kwikota yesithathu yokuqala yokusetyenziswa kwamalahle kwanda ngokukhawuleza unyaka nonyaka, kwaye izinga lokukhula ngokuthe ngcembe lawa.Ukusukela ekuqaleni kulo nyaka, unikezelo lwemarike yamalahle yaseTshayina kunye nemfuno ngokuqhelekileyo iqinile, uluhlu lwamalahle kwikhonkco ngalinye liphantsi, kwaye amaxabiso emarike yamalahle aqhutywe phezulu.Ngaphantsi kwenkxaso yexabiso eliphezulu lemarike yamalahle, ukuthunyelwa kweemarike ze-coke zasekhaya kunye nesulfure ephezulu yesulfure. kwakha ukutsalwa okulungileyo, ukuxhasa ixabiso lentengo ye-oyile ye-coke yenyuka ukuya kwinqanaba eliphezulu.Kwikota yesine, njengoko urhulumente waqala ukulawula kunye nokungenelela kwimarike yamalahle, amaxabiso amalahle awela kakhulu, ukuthunyelwa kwe-high-sulfur coke market. kwacotha, kwaye ukungeniswa kwe-coke kunye namaxabiso e-oyile yasekhaya ehla ngokufanelekileyo.
Ngokubanzi, ngo-2021, imfuno yokuphela kokuthengwa kwempahla ilungile, kwaye izixhobo ezitsha zokuvelisa ezantsi ziqalisiwe. Nangona imfuno iyancipha kancinci phantsi kwempembelelo yolawulo oluphindwe kabini, isenza inkxaso eqinile kwimarike yeoli kunye ne-coke, kwaye ixabiso le-coke liyaqhubeka nokugcina ukusebenza okuphezulu. kugxininiswe kwintsimi ye-anode ebhakiweyo kwangaphambili kunye ne-aluminiyam ye-electrolytic. Imarike ye-aluminium ye-carbon iyaqhubeka ithengisa kakuhle, ixabiso lemarike ye-terminal liphezulu, umthwalo wokuqala we-electrolytic aluminium amashishini aphezulu, kwaye imfuno ye-petroleum coke ingaqhubeka nokunyuka.
