Zipangizo zazikulu zomwe zimagwiritsidwa ntchito popanga ma electrode a graphite ndi calcined petroleum coke. Ndiye ndi mtundu wanji wa calcined petroleum coke woyenera kupanga ma electrode a graphite?
1. Kukonzekera mafuta osaphika a coking kuyenera kukwaniritsa mfundo yopanga mafuta osaphika a petroleum coke apamwamba kwambiri, ndipo zilembo za mafuta osaphika a petroleum coke apamwamba ziyenera kukhala ndi kapangidwe ka ulusi wambiri. Machitidwe opangira akuwonetsa kuti kuwonjezera 20-30% ya mafuta osaphika a coking mu mafuta osaphika a coking kuli ndi ubwino wabwino, zomwe zingakwaniritse zofunikira pakupanga ma electrode a graphite.
2. Mphamvu yokwanira yomanga.
M'mimba mwake wa zinthu zopangira usanayambe kuphwanyidwa, kusungunuka, nthawi yophwanyidwa kuti muchepetse kuphwanyidwa, kukwaniritsa zofunikira pakukonza kukula kwa tirigu wa sikweya.
3. Kusintha kwa voliyumu ya coke kuyenera kukhala kochepa pambuyo poti yasweka, zomwe zimachepetsa kupsinjika kwamkati mwa chinthucho chifukwa cha kutupa kwa chinthu chosindikizidwa komanso kuchepa kwa njira yokazinga ndi graphitization.
4. Coke iyenera kukhala yosavuta kuyika graphitization, zinthu ziyenera kukhala ndi kukana kochepa, kutentha kwambiri komanso kufalikira kwa kutentha pang'ono.
5. Kusakhazikika kwa coke kuyenera kukhala kochepera 1%,Chotupa chosinthasintha chimasonyeza kuzama kwa coking ndipo chimakhudza zinthu zingapo.
6. Coke iyenera kuotchedwa pa 1300℃ kwa maola 5, ndipo mphamvu yake yeniyeni iyenera kukhala yosachepera 2.17g/cm2.
7. Sulfure yomwe ili mu coke siyenera kupitirira 0.5%.
North America ndi South America ndi omwe amapanga kwambiri petroleum coke padziko lonse lapansi, pomwe Europe imadzidalira yokha mu petroleum coke. Opanga kwambiri petroleum coke ku Asia ndi Kuwait, Indonesia, Taiwan ndi Japan ndi mayiko ena ndi madera ena.
Kuyambira m'ma 1990, chifukwa cha kupita patsogolo kwachuma cha China, kufunikira kwa mafuta kwakhala kukuwonjezeka chaka ndi chaka.
Pamene kuchuluka kwa mafuta osakonzedwa bwino kukuwonjezeka kwambiri, mafuta ambiri a petroleum coke, omwe amapangidwa kuchokera ku mafuta osakonzedwa bwino, adzapangidwa mosakayikira.
Malinga ndi kufalikira kwa mafuta a coke m'chigawo cha China, dera la kum'mawa kwa China lili pa nambala 1, ndipo limaphatikizapo zoposa 50% ya mafuta onse a coke m'chigawo cha China.
Ikutsatiridwa ndi dera la kumpoto chakum'mawa ndi dera la kumpoto chakumadzulo.
Kuchuluka kwa sulfure mu petroleum coke kumachita gawo lofunika kwambiri pakugwiritsa ntchito kwake ndi mtengo wake, ndipo kupanga petroleum coke yokhala ndi graphitized kumachepetsedwa ndi malamulo okhwima okhudza chilengedwe kunja, omwe amaletsa kuyaka kwa petroleum coke yokhala ndi sulfure yambiri m'malo ambiri opangira mafuta ndi mafakitale amphamvu mdzikolo.
Coke ya petroleum yapamwamba komanso ya sulfure yochepa imagwiritsidwa ntchito kwambiri m'mafakitale achitsulo, aluminiyamu ndi kaboni. Kufunika kwakukulu kwa coke ya petroleum kumawonjezera mtengo wake kangapo.
M'zaka zaposachedwapa, kugwiritsidwa ntchito kwa petroleum coke ku China kukupitirira kukula mofulumira kwambiri, ndipo kufunikira kwa petroleum coke m'misika yonse ya ogula kukupitilira kukula.
Aluminiyamu imawononga mafuta ochulukirapo kuposa theka la mafuta onse a coke ku China. Amagwiritsidwa ntchito kwambiri mu anode yophikidwa kale, ndipo kufunikira kwa coke ya sulfure yapakatikati ndi yotsika ndi kwakukulu.
Zinthu zopangidwa ndi kaboni zimafunika pafupifupi gawo limodzi mwa magawo asanu a mafuta a coke, omwe amagwiritsidwa ntchito kwambiri pokonzekera ma electrode a graphite. Ma electrode apamwamba a graphite ali ndi phindu lalikulu ndipo ndi opindulitsa kwambiri.
Mafuta amagwiritsidwa ntchito pafupifupi gawo limodzi mwa magawo khumi, ndipo mafakitale amagetsi, mafakitale a porcelain ndi magalasi amagwiritsa ntchito kwambiri.
Chiŵerengero cha kugwiritsidwa ntchito kwa mafakitale osungunula ndi chimodzi mpaka makumi awiri, kugwiritsa ntchito chitsulo chopangira chitsulo chopangira chitsulo.
Kuphatikiza apo, kufunikira kwa makampani opanga silicon ndi mphamvu yofunika kuganiziridwa.
Gawo lotumiza kunja ndilo gawo lochepa kwambiri, koma kufunikira kwa coke yamafuta apamwamba pamsika wakunja kukuyenerabe kuyembekezeredwa. Palinso gawo lina la coke yamafuta ambiri, komanso kugwiritsidwa ntchito m'nyumba.
Ndi chitukuko cha chuma cha China, mafakitale achitsulo aku China, zosungunulira aluminiyamu ndi maubwino ena azachuma pang'onopang'ono zinakula, kuti awonjezere kutulutsa ndi ubwino wa zinthu, mabizinesi ambiri akuluakulu pang'onopang'ono agula mafuta ophikira carbonizer okhala ndi graphenized. Kufunika kwa dziko kukuwonjezeka. Nthawi yomweyo, chifukwa cha mtengo wokwera wogwirira ntchito, ndalama zambiri zogulira komanso zofunikira kwambiri pakupanga mafuta ophikira graphitized, palibe mabizinesi ambiri opanga ndipo pakadali pano pali mpikisano wochepa, kotero, msika ndi waukulu, kupezeka ndi kochepa, ndipo kupezeka konse kuli pafupifupi kochepa kuposa komwe kukufunika.
Pakadali pano, msika wa petroleum coke ku China uli ndi zinthu zambiri za sulfure petroleum coke, zomwe zimagwiritsidwa ntchito kwambiri ngati mafuta; zinthu zochepa za sulfure petroleum coke zimagwiritsidwa ntchito kwambiri mu metallurgy ndi kutumiza kunja; Zinthu zapamwamba za petroleum coke ziyenera kutumizidwa kunja.
Njira yopangira mafuta akunja a coke calcination imamalizidwa mu fakitale yoyeretsera, mafuta a coke opangidwa ndi fakitaleyo amapita mwachindunji mu gawo la calcination kuti akayeretsere.
Popeza palibe chipangizo choyezera calcium m'mafakitale oyezera calcium m'nyumba, mafuta a coke opangidwa ndi mafakitale oyezera calcium amagulitsidwa pamtengo wotsika. Pakadali pano, mafuta a coke opangidwa ndi malasha ku China amapangidwa m'makampani opanga zitsulo, monga mafakitale a carbon, mafakitale a aluminiyamu, ndi zina zotero.
