Waukulu zopangira ntchito kupanga graphite elekitirodi ndi calcined petroleum coke. Ndiye ndi mtundu wanji wa calcined petroleum coke womwe uli woyenera kupanga graphite elekitirodi?
1. Kukonzekera kuphika mafuta aiwisi kuyenera kugwirizana ndi mfundo yopangira mafuta abwino kwambiri a petroleum coke, ndipo zilembo zamtengo wapatali za petroleum coke ziyenera kukhala ndi ulusi wambiri. Zochita zopanga zikuwonetsa kuti kuwonjezera 20-30% yotsalira yotsalira yamafuta mu coking mafuta yaiwisi imakhala yabwinoko, yomwe imatha kukwaniritsa zofunikira za graphite electrode.
2. Mphamvu zokwanira zamapangidwe.
The zopangira awiri chisanadze kuphwanya, kusungunuka, kuphwanya nthawi kuchepetsa pulverization, kukwaniritsa zofunika batching lalikulu njere kukula zikuchokera.
3. Kusintha kwa voliyumu ya coke kuyenera kukhala kochepa mutatha kusweka, zomwe zingathe kuchepetsa kupsinjika kwa mkati mwa mankhwala omwe amayamba chifukwa cha kubwereranso kwa mankhwala oponderezedwa ndi kuchepa kwa njira yowotcha ndi graphitization.
4. Coke iyenera kukhala yosavuta graphitization, mankhwala ayenera kukhala otsika kukana, mkulu matenthedwe madutsidwe madutsidwe ndi otsika coefficient cha kukulitsa matenthedwe.
5. Kutentha kwa coke kuyenera kukhala kosakwana 1%,Nkhani yosasinthika imasonyeza kuya kwa coking ndipo imakhudza mndandanda wa katundu.
6. Coke iyenera kuotchedwa pa 1300 ℃ kwa maola 5, ndipo mphamvu yokoka yeniyeni sayenera kukhala yosachepera 2.17g/cm2.
7. Sulfure mu coke sayenera kupitirira 0.5%.
Kumpoto kwa America ndi South America ndi omwe amapanga mafuta ambiri padziko lonse lapansi, pomwe Europe imadzidalira yokha pa petroleum coke. Omwe amapanga mafuta a petroleum coke ku Asia ndi Kuwait, Indonesia, Taiwan ndi Japan ndi mayiko ena ndi madera.
Kuyambira m'ma 1990, ndikukula mwachangu kwachuma cha China, kufunikira kwamafuta kukukulirakulira chaka ndi chaka.
Kuchulukirachulukira kwa mafuta opangira mafuta kumachulukirachulukira, petroleum coke yambiri, yomwe imapangidwa kuchokera pakuyenga mafuta osakanizidwa, idzapangidwa mosakayika.
Malinga ndi kagawidwe kagawo ka mafuta a petroleum coke ku China, chigawo chakum'mawa kwa China ndichoyamba, chomwe chimaposa 50% yazinthu zonse zotulutsa mafuta ku China.
Imatsatiridwa ndi chigawo cha kumpoto chakum'mawa ndi kumpoto chakumadzulo.
Mafuta a sulfure a petroleum coke amatenga gawo lalikulu pakugwiritsa ntchito kwake komanso mtengo wake, ndipo kupanga mafuta a graphitized petroleum coke kumachepetsedwa ndi malamulo okhwima a chilengedwe kunja, omwe amaletsa kuwotcha mafuta a petroleum coke okhala ndi sulfure wambiri m'mafakitale ambiri ndi magetsi. dziko.
Mafuta a sulfure apamwamba komanso otsika kwambiri amagwiritsidwa ntchito kwambiri m'mafakitale azitsulo, aluminiyamu ndi mpweya. Kufunika kowonjezereka kumawonjezera mtengo wa petroleum coke kangapo.
M'zaka zaposachedwa, kugwiritsidwa ntchito kwa petroleum coke ku China kukukulirakulirabe, ndipo kufunikira kwa mafuta a petroleum coke m'misika yonse yogula kukukulirakulira.
Aluminiyamu amawerengera theka lazakudya zonse zamafuta a petroleum ku China. Amagwiritsidwa ntchito kwambiri mu anode yophika kale, ndipo kufunikira kwa coke yapakati ndi yotsika sulfure ndikwabwino.
Zogulitsa za carbon zimatenga pafupifupi gawo limodzi mwa magawo asanu a kufunika kwa mafuta a petroleum coke, omwe amagwiritsidwa ntchito kwambiri popanga ma electrode a graphite. Ma electrode apamwamba a graphite ali ndi mtengo wapamwamba ndipo ndi opindulitsa kwambiri.
Kugwiritsa ntchito mafuta kumakhala pafupifupi gawo limodzi mwa magawo khumi, ndipo mafakitale amagetsi, zopangira ma porcelain ndi magalasi amagwiritsa ntchito zambiri.
Kusungunuka kwa mafakitale osungunula chiŵerengero cha chimodzi - makumi awiri, kugwiritsira ntchito zitsulo zopangira zitsulo.
Kuphatikiza apo, kufunikira kwamakampani a silicon ndikoyeneranso kuwerengedwa.
Gawo lotumiza kunja limakhala laling'ono kwambiri, koma kufunikira kwa mafuta amafuta apamwamba kwambiri pamsika wakunja ndikofunikira kuyang'anabe. Palinso gawo lina la coke yapamwamba ya sulfure, komanso kumwa mowa m'nyumba.
Ndi chitukuko cha chuma China, China zoweta zitsulo mphero, zosungunula zotayidwa ndi ubwino zina zachuma pang'onopang'ono bwino, pofuna kuonjezera linanena bungwe ndi khalidwe la mankhwala, mabizinesi akuluakulu ambiri pang'onopang'ono anagula graphenized petroleum coking carbonizer.Kufuna kwapakhomo akuwonjezeka. nthawi yomweyo, chifukwa cha kukwera mtengo kwa ntchito, likulu lalikulu lazachuma komanso zofunikira zapamwamba zaukadaulo popanga graphitized petroleum coke, palibe mabizinesi ambiri opanga komanso kupanikizika kocheperako pakali pano, kunena kuti, msika ndi waukulu. ang'onoang'ono, ndipo zonse zoperekedwa ndi pafupifupi zochepa kuposa kufunika.
Pakadali pano, msika waku China wamafuta amafuta amafuta amafuta amafuta amafuta amafuta amafuta amafuta amafuta amafuta amafuta a sulfure owonjezera, omwe amagwiritsidwa ntchito ngati mafuta; Zogulitsa zotsika za sulfure zamafuta amafuta zimagwiritsidwa ntchito kwambiri popanga zitsulo ndi kutumizira kunja; Zogulitsa zamafuta amafuta amafuta apamwamba zimayenera kutumizidwa kunja.
Njira yowerengera mafuta akunja a petroleum coke calcination imatsirizidwa mu makina oyeretsera, mafuta a petroleum coke opangidwa ndi oyeretsera amapita mwachindunji mugawo la calcination la calcination.
Popeza palibe chipangizo cha calcination m'mafakitale a m'nyumba, mafuta a petroleum coke opangidwa ndi oyeretsa amagulitsidwa motsika mtengo.Pakali pano, mafuta a ku China a coke ndi malasha amapangidwa m'makampani opanga zitsulo, monga carbon plant, aluminiyamu chomera, etc.
