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 ndi otsika coefficient cha matenthedwe kukula.
5. Kutentha kwa coke kuyenera kukhala kosakwana 1%,Nkhani yosasunthika imasonyeza kuya kwa coking ndipo imakhudza mndandanda wa katundu.
6. Coke iyenera kuotchedwa pa 1300 ℃ kwa maola 5, ndipo mphamvu yokoka yeniyeni iyenera kukhala yosachepera 2.17g/cm2.
7. Sulfure mu coke sayenera kupitirira 0.5%.
Kumpoto kwa America ndi ku South America ndi omwe amapanga mafuta a coke padziko lonse lapansi, Pomwe ku Europe ndikokwanira pawokha 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, mafuta ambiri a petroleum coke, omwe amapangidwa kuchokera pakuyenga mafuta osakanizidwa, amapangidwa mosapeweka.
Malinga ndi kagawidwe kagawo ka mafuta a petroleum coke ku China, dera lakum'mawa kwa China ndiloyamba, lomwe ndi loposa 50% lazinthu 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 graphitized petroleum coke kumachepetsedwa ndi malamulo okhwima achilengedwe akunja, omwe amaletsa kuwotcha mafuta a coke okhala ndi sulfure wambiri m'malo ambiri oyeretsera ndi magetsi. dziko.
Mafuta a sulfure apamwamba komanso otsika kwambiri amagwiritsidwa ntchito kwambiri m'mafakitale achitsulo, 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 kufunikira 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 kumatenga pafupifupi gawo limodzi mwa magawo khumi, ndipo mafakitale opanga magetsi, zadothi 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 coke yapamwamba kwambiri yamafuta pamsika wakunja ndikofunikira kuyang'anabe.Palinso gawo lina la coke yapamwamba-sulfure, komanso kumwa mowa m'nyumba.
Ndi chitukuko cha chuma China, China zoweta zitsulo mphero, zosungunula zotayidwa ndi zopindulitsa 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 mafuta a petroleum graphitized, 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 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 makina oyeretsera amapita mwachindunji kugawo la calcination la calcination.
Popeza palibe chipangizo cha calcination m'mafakitale a m'nyumba, mafuta a petroleum coke opangidwa ndi makina oyeretsera amagulitsidwa motsika mtengo.
