Kumbali ya zopangira zopangira zamagetsi zopanda mphamvu, mafakitale opangira mafuta a PetroChina ndi CNOOC akupitilizabe kukakamizidwa kutumiza zinthu zopangidwa ndi coke ya sulfure yochepa, ndipo mitengo ya malonda pamsika ikupitirirabe kutsika. Pakadali pano, mtengo wa zopangira zopangira za graphite ndi ndalama zokonzera graphitization watsika, ndipo mphamvu yopangira ya mbali yoperekera yatulutsidwa. Mphamvu yopangira mitundu yotsika komanso yapakati ya graphite yopangidwa pamsika yakhala yokwera pang'onopang'ono, zomwe zapangitsa kuti mitengo ya zinthuzi itsike. Graphite yachilengedwe ya electrode yoyipa ndi 39,000-42,000 yuan/tani, graphite yopangidwa ndi 50,000-60,000 yuan/tani, ndipo mesocarbon microspheres ndi 60-75,000 yuan/tani.
Kuchokera pa mtengo, singano ya coke ndi low-sulfur coke, zinthu zopangira graphite, zimakhala pafupifupi 20%-30% ya kapangidwe ka mtengo, ndipo mtengo wa zinthu zopangira watsika kuyambira kotala lachitatu.
Mtengo wamsika wa mafuta a coke otsika-sulfur unasinthasintha pang'ono, ndipo mtengo wa 2# ku East China ndi South China unatsika ndi 200 yuan/tani, ndipo mtengo wapano ndi 4600-5000 yuan/tani. Ponena za bizinesi yayikulu, Huizhou CNOOC 1#B inatsika ndi 600 yuan/tani kufika pa 4750 yuan/tani. Malo oyeretsera mafuta ku Shandong anatsika pang'ono, ndipo katundu wotumizidwa anatsekedwa pang'ono. Kutsika kwa mtengo wa mafuta a coke kwakweza phindu la makampani a calcined coke, ndipo ntchito ya makampani a calcined coke yakhala yokhazikika. Mtengo wa mafuta a slurry otsika-sulfur, zopangira za needle coke, unapitirira kutsika ndipo pakadali pano uli pa 5,200-5,220 yuan/tani. Makampani ena a needle coke okhala ndi mafuta anaimitsa kwakanthawi mayunitsi opanga ma coke, kuchuluka kwa ma needle coke okwanira, makampani a malasha akupitilizabe kutayika, ndipo nthawi yoyambira ikadali yoti idziwike.
Mtengo wokonza zithunzi unakhala pafupifupi 50%. Mu kotala lachitatu, chifukwa cha kutulutsidwa kwa mphamvu zopangira zinthu, kusiyana kwa msika kunachepa pang'onopang'ono, ndipo ndalama zolipirira zinthu zinayamba kuchepa.
Poganizira za kupezeka kwa magetsi, kotala lachitatu linayamba kulowa mu nthawi ya kukula kwakukulu kwa kupanga ma electrode oipa. Mapulojekiti oyamba opanga ma electrode oipa pang'onopang'ono anafika pamlingo wokwanira wopanga ndipo mapulojekiti atsopano anatulutsidwa mwachangu. Kupezeka kwa magetsi pamsika kunawonjezeka mofulumira.
Komabe, nthawi yopangira graphite yopangira ndi yayitali, ndipo mtengo wa anode ndi graphitization wakambirana kwa magawo angapo chaka chino. Mu kotala lachitatu, fakitale ya anode ndi yomwe ili pansi pake ili pamlingo wokwera mtengo. Ngakhale kuti mtengo wa malonda watsika, sizikutanthauza kuti mtengo watsika kwambiri.
Mu kotala lachinayi, makamaka kuyambira Novembala, mafakitale a mabatire akhala akugwira ntchito zambiri zosungiramo zinthu, ndipo kufunikira kwa ma anode kwachepa; ndipo pankhani yopereka, kuwonjezera pa mphamvu yatsopano yopangira ya opanga ma anode achikhalidwe omwe atulutsidwa pang'onopang'ono chaka chino, palinso mafakitale ang'onoang'ono kapena atsopano a anode omwe awonjezera mphamvu zatsopano chaka chino. Ndi kutulutsidwa kwa mphamvu yopangira, mphamvu ya ma electrode oyipa ya mitundu yotsika ndi yapakati pamsika ikuchulukirachulukira pang'onopang'ono; mtengo wa end-coke ndi graphitization watsika, zomwe zapangitsa kuti mitengo ya zinthu zotsika ndi zapakati pa electrode yoyipa itsike kwambiri.
Pakadali pano, zinthu zina zotsika mtengo komanso zapakati zomwe zimadziwika bwino kwambiri zikuchepetsa mitengo, pomwe zinthu zina zapamwamba zomwe zili ndi ubwino waukadaulo kuchokera kwa opanga akuluakulu sizikugulitsidwa mwachangu kwambiri kapena kusinthidwa, ndipo mitengo idzakhalabe yokhazikika pakapita nthawi yochepa.
Mphamvu yopangira ya electrode yoyipa ndi yochulukirapo, koma chifukwa cha mphamvu ya ndalama, ukadaulo, ndi kayendedwe kake ka pansi, mabizinesi ena a electrode yoyipa achedwetsa nthawi yopangira.
Poganizira za msika wamagetsi woipa wonse, chifukwa cha mphamvu ya ndondomeko yothandizira, kukula kwa msika wa magalimoto atsopano operekera mphamvu ndi kochepa, ndipo mafakitale ambiri a mabatire amagwiritsa ntchito zinthu zambiri. Izi zimagwirizananso ndi tsiku losainira pangano chaka chamawa.
Kukonza Magalasi: Mavuto okhudzana ndi kayendedwe ka zinthu ndi mayendedwe omwe abwera chifukwa cha mliriwu ku Inner Mongolia ndi madera ena achepa, koma chifukwa cha mphamvu zopangira ndi zopangira, mtengo wa kukonza magalasi a OEM ukadali wotsika, ndipo chithandizo chamtengo wapatali cha zinthu zopangira magalasi a graphite chikupitilizabe kufooka. Pakadali pano, kuti azitha kuwongolera ndalama ndikuchepetsa chiopsezo cha kusokonekera kwa zinthu, mafakitale ambiri a anode amasankha kukhazikitsa unyolo wathunthu wa mafakitale kuti awonjezere mpikisano wawo. Pakadali pano, mtengo waukulu wa magalasi ambiri ndi 17,000-19,000 yuan/tani. Zinthu zosungiramo uvuni ndi zophikira zili zambiri ndipo mitengo yake ndi yokhazikika.
