Iindawo eziphambili zokusetyenziswa kweemveliso ze-petroleum coke zaseTshayina zisagxininwe kwi-anode ebhakiweyo kwangaphambili, ipetroli, i-carbonator, i-silicon (kubandakanya i-silicon metal kunye ne-silicon carbide) kunye ne-graphite electrode, phakathi kwazo ukusetyenziswa kwentsimi ye-anode ebhakiweyo kwangaphambili kuphezulu. Kwiminyaka yakutshanje, inzuzo yemveliso yemarike ye-aluminium ye-electrolytic kunye neemveliso ze-silicon iyaqhubeka nokuba phezulu, kwaye amashishini asezantsi anomdla wokuthenga kunye nokuvelisa, nto leyo eye yaba yeyona nto iphambili ekukhuleni kokusetyenziswa kwe-petroleum coke.
Itshati yolwakhiwo lokusetyenziswa kwe-coke yepetroliyam yaseTshayina ngo-2021
Ngowama-2021, intsimi yokusetyenziswa kwe-petroleum coke yaseTshayina isasetyenziswa njenge-anode, ipetroli, i-silicon, i-carbonizer, i-graphite electrode kunye nezinto ze-anode.
Kuwo wonke unyaka, inzuzo ye-aluminium ye-electrolytic, i-silicon metal kunye ne-silicon carbide ifikelele kwinqanaba eliphezulu, kwaye amashishini anomdla omkhulu wokuqalisa ukwakha. Nangona kunjalo, njengeshishini elisebenzisa amandla amaninzi, imveliso iyonke ichaphazeleka kakhulu kukuncitshiswa kwamandla. Nangona imfuno ingenakukhutshwa ngokupheleleyo, imfuno ye-petroleum coke isakhula.
Ngokuphathelele amafutha, phantsi kwemvelaphi yokunqongophala kwamalahle, iifektri zokucoca ziyandisa ukuzisebenzisela zona, zonyusa umthamo wokuthenga kunye nemfuno entle iyonke; Ngo-2021, izityalo zeglasi zinenzuzo entle, izinga eliphezulu lokusetyenziswa kunye nemfuno entle ye-petroleum coke. Imfuno entle yezinto ezingezizo ze-electrode ikwaqhuba ukuveliswa kwee-agents eziphucula ikhabhoni. Imfuno yee-electrode ze-silicon ilungile, kodwa imfuno yee-electrode ze-graphite zentsimbi iyonke.
Itshathi yendlela yokuxabisa i-coke e-calcined yasekhaya ngo-2021
Kwisiqingatha sokuqala sowama-2021, ixabiso lasekhaya le-sulfur calcination coke eliphantsi kwe-sulfur libonise umkhwa wokunyuka kuqala uze emva koko wehle. Kwisiqingatha sesibini sonyaka, inkxaso yokuphela kwemfuno yayizinzile, kwaye ixabiso le-calcination coke laqhubeka linyuka. Ixhaswa ngamaxabiso ezinto eziluhlaza, amaxabiso e-calcined coke anyuke kakhulu, kwaye ixabiso lentengiselwano kwikota yokuqala lenyuke nge-2,850 yuan / ton. Kwisiqingatha sesibini sonyaka, imfuno ephantsi echaphazeleka kukuthintela amandla kunye nomgaqo-nkqubo wolawulo oluphindwe kabini yaba buthathaka, kodwa imakethi yezinto ze-electrode ezimbi ibonise inkxaso elungileyo, umgangatho ophezulu kunye nexabiso le-sulfur coke eliphantsi laqhubeka linyuka, ixabiso le-sulfur calcination coke eliphantsi lenyuka ngokufanelekileyo, kwaye ixabiso lentengiselwano ye-calcination coke kwikota yesine lenyuke laya kwinqanaba eliphezulu lonyaka.
Ngo-2021, ixabiso le-coke yeoyile yesulfure eliphakathi neliphezulu lasekhaya ngokusisiseko labonisa ukunyuka ngakunye, kwaye ixabiso le-aluminium ye-electrolytic terminal lenyuke laya kwinqanaba eliphezulu kwimbali kulo nyaka. Intshiseko yemarike ye-aluminium carbon yokungena kwimarike yayiphezulu, kwaye phantsi kwenkxaso yesiphelo semfuno, ixabiso le-coke ye-sulfur calcined coke ngokusisiseko lagcina umkhwa wokunyuka. Ekuqaleni kukaNovemba, ngenxa yokwehla rhoqo kwexabiso le-coke ye-petroleum yezinto eziluhlaza, ixabiso le-coke ye-calcined lehle kancinci, kodwa ixabiso lilonke lalisephezulu kunexesha elifanayo kunyaka ophelileyo.
Itshati yamaxabiso e-coke yesulfure ephakathi yasekhaya kunye ne-anode ebhakiweyo kwangaphambili ngo-2021
Ngowama-2021, ngenxa yokunyuka okukhulu kwemarike yesiphelo, ixabiso le-anode ebhakiweyo kwangaphambili lenyuke laya kwinqanaba eliphezulu. Ixabiso eliqhelekileyo lonyaka le-anode ebhakiweyo kwangaphambili yayiyi-4,293 yuan / itoni, kwaye ixabiso eliqhelekileyo lonyaka lenyuke nge-1,523 yuan / itoni okanye i-54.98% xa kuthelekiswa nelo langowama-2020.
Kwisiqingatha sokuqala sonyaka, amashishini e-anode abhakiweyo ngaphambili asekhaya aqala kancinci, echaphazeleka kakhulu ngamaxabiso ezinto eziluhlaza. Kwisiqingatha sesibini sonyaka, ukwakhiwa kwehla ngenxa yempembelelo yokulawula kabini kunye nokwahlulwa kwamandla kwezinye iindawo, kodwa ixabiso lilonke lalisaqhubeka liphezulu, kwaye imfuno ye-coke yesulfur ephakathi yayizinzile, kwaye impembelelo yexabiso le-coke yesulfur ephakathi kwixabiso le-anode ebhakiweyo kwangaphambili yandiswa. Amashishini e-aluminium e-electrolytic terminal ayaqhubeka nokusebenza ngexabiso eliphezulu, kwaye ukukhululwa kwamandla amatsha emveliso yamashishini e-aluminium kwenza inkxaso esebenzayo yokuthunyelwa kwemarike ye-anode ebhakiweyo kwangaphambili. NgoDisemba, amaxabiso e-anode ebhakiweyo kwangaphambili ehla ngenxa yokwehla kwamaxabiso ezinto eziluhlaza, kodwa unyaka wonke, ixabiso laliphezulu kakhulu kunelo lexesha elifanayo kunyaka ophelileyo.
Itshathi yamaxabiso e-carbonizer yasekhaya ngo-2021
Ngowama-2021, urhwebo lwemarike yeearhente zekhabhoni zasekhaya lulungile. Iqhutywa yimarike yezinto eziluhlaza kunye nezinto ze-cathode, ixabiso leearhente zekhabhoni liye latshintsha kwisiqingatha sokuqala sonyaka. Kwisiqingatha sesibini sonyaka, laqala ukunyuka kakhulu ngexabiso lezinto eziluhlaza, kwaye ixabiso leearhente zekhabhoni nalo libonise umkhwa wokunyuka oguquguqukayo.
Kuwo wonke unyaka, ixabiso le-calcium coke carbon increasing agent likhokelela ekunqongophaleni kwezixhobo ze-petroleum coke zasekhaya kwiindawo zokucoca zasekhaya (ukugcinwa kwezixhobo ze-calcium coke kunye namalahle kuncinci). Bechaphazeleka ziindleko zezinto eziluhlaza kunye nemfuno ephantsi, abanye abavelisi be-graphite carbonizer bafumana ikakhulu iindleko zokucubungula izinto ze-electrode ezimbi, nto leyo ebangela ukuba ukwanda kwe-Graphite carbonizer kuncinci kakhulu kunezo zezinto eziluhlaza. Kwikota ezintathu zokuqala, ixabiso lalisebenza ngokuzinzileyo, kwaye ikota yesine yaqala ukufuna ukuqhuba ixabiso.
Itshathi yamaxabiso alinganayo e-thermal coal kunye ne-petroleum coke ngo-2021
Kwikota ezintathu zokuqala zowama-2021, uqoqosho olukhulu lwaseTshayina luqhubekile nokuchacha kancinci, kwaye ukusetyenziswa kombane kunyuke nge-12.9% unyaka nonyaka. Imfuno yamandla yanda ngokukhawuleza, kwaye imveliso yamandla emanzi imbi, ukuveliswa kwamandla obushushu kwanda nge-11.9% kwiinyanga ezili-9 zokuqala unyaka nonyaka, kwaye imfuno yamalahle ashushu yanda ngokukhawuleza, nto leyo ebangela ukukhula kokusetyenziswa kwamalahle. Phantsi kwempembelelo yokunciphisa ukukhutshwa kwekhabhoni, "ulawulo oluphindwe kabini lokusetyenziswa kwamandla" kunye nokuthintela uphuhliso olungabonakaliyo lweeprojekthi "ezimbini eziphezulu", amandla emveliso yentsimbi, izixhobo zokwakha kunye namashishini eekhemikhali ancipha kancinci kancinci, izinga lokukhula kwemveliso yentsimbi yehagu, i-coke, isamente kunye nezinye iimveliso ezinxulumene nayo lancipha, kwaye ukusetyenziswa kwamalahle kumashishini entsimbi kunye nezixhobo zokwakha kwehla ngokufanelekileyo. Ngokubanzi, ukusetyenziswa kwamalahle eTshayina kwiikota ezintathu zokuqala zokusetyenziswa kwamalahle kwanda ngokukhawuleza unyaka nonyaka, kwaye izinga lokukhula lancipha kancinci kancinci. Ukusukela ekuqaleni kwalo nyaka, ukubonelela kunye nemfuno yemarike yamalahle yaseTshayina ngokubanzi kuxinene, uluhlu lwamalahle kwikhonkco ngalinye liphantsi, kwaye amaxabiso emarike yamalahle aqhutywa phezulu. Phantsi kwenkxaso yamaxabiso aphezulu emarike yamalahle, ukuthunyelwa kwemarike ye-coke yasekhaya neyangaphandle ye-sulfur yakha umtsalane omhle, ukuxhasa ixabiso lentengiselwano ye-coke yeoyile lenyuka laya kwinqanaba eliphezulu. Kwikota yesine, njengoko urhulumente eqala ukulawula kwaye Ukungenelela kwimarike yamalahle, amaxabiso amalahle ehla kakhulu, ukuthunyelwa kwemarike ye-coke ene-sulfur ephezulu kwehla, kwaye ukungeniswa kwe-coke kunye ne-oyile ye-coke yasekhaya kwehla ngokufanelekileyo.
Ngokubanzi, ngo-2021, umdla wokuthengwa kweemfuno ulungile, kwaye izixhobo ezintsha zemveliso ezisezantsi ziqalisiwe. Nangona imfuno ibuthathaka kancinci phantsi kwempembelelo yolawulo oluphindwe kabini, isakha inkxaso enamandla kwimarike yeoyile kunye ne-coke, kwaye ixabiso le-coke liyaqhubeka nokusebenza okuphezulu. Kwiminyaka yakutshanje, ukwehla kwe-petroleum coke yasekhaya kugxile kakhulu kwicandelo le-anode ebhakiweyo kwangaphambili kunye ne-electrolytic aluminium. Imarike ye-aluminium carbon iyaqhubeka nokurhweba kakuhle, ixabiso lemarike yokugqibela liphezulu, umthwalo wokuqala wamashishini e-electrolytic aluminium uphezulu, kwaye imfuno ye-petroleum coke inokuqhubeka ikhula.
