"Msika wapadziko lonse lapansi wa graphite electrode unali wamtengo wapatali wa $ 9.13 biliyoni mu 2018 ndipo ukuyembekezeka kufika $ 16.48 biliyoni pofika 2025, ndi chiwonjezeko chapachaka cha 8.78% panthawi yolosera."
Pakuchulukirachulukira kwakupanga zitsulo komanso kutukuka kwa zomangamanga zamakono, kufunikira kwa zomangamanga ndi zomangamanga kukukulirakulira, zomwe ndi zina mwazinthu zofunika zomwe zikuyendetsa kukula kwa msika wapadziko lonse wa graphite electrode.

Ma electrode a graphite ndi zinthu zotenthetsera zomwe zimagwiritsidwa ntchito m'ng'anjo zamagetsi zamagetsi kuti apange zitsulo kuchokera ku zinyalala, magalimoto akale ndi zida zina.Ma elekitirodi amapereka kutentha kwa chitsulo chosungunula kuti asungunuke kuti apange chitsulo chatsopano.Zida zamagetsi zamagetsi zimagwiritsidwa ntchito kwambiri m'mafakitale opangira zitsulo ndi aluminiyamu chifukwa ndizotsika mtengo kupanga.Ma electrode a graphite amatha kusonkhanitsidwa kukhala masilindala chifukwa ndi gawo la chivundikiro cha ng'anjo yamagetsi.Mphamvu yamagetsi yomwe imaperekedwa ikadutsa maelekitirodi a graphite, arc yamphamvu yamagetsi imapangidwa, kusungunula zitsulo zotsalira.Malingana ndi kufunikira kwa kutentha ndi kukula kwa ng'anjo yamagetsi, maelekitirodi amitundu yosiyanasiyana angagwiritsidwe ntchito.Kuti apange tani imodzi yachitsulo, pafupifupi 3 kg ya maelekitirodi a graphite amafunikira.Popanga zitsulo, graphite imatha kupirira kutentha kwambiri, kotero kutentha kwa nsonga ya electrode kumafika pafupifupi madigiri 3000 Celsius.Singano ndi petroleum coke ndizo zida zazikulu zomwe zimagwiritsidwa ntchito popanga ma electrode a graphite.Zimatenga miyezi isanu ndi umodzi kupanga ma electrode a graphite, ndiyeno njira zina, kuphatikizapo kuphika ndi kuphikanso, zimagwiritsidwa ntchito kutembenuza coke kukhala graphite.Ma elekitirodi a graphite ndi osavuta kupanga kuposa ma elekitirodi amkuwa, ndipo liwiro lopanga limayenda mwachangu chifukwa sikutanthauza njira zowonjezera monga kugaya pamanja.
Kumanga msika wa graphite electrode, kuchuluka kwa chitsulo m'mafakitale amafuta ndi gasi ndi magalimoto akuyembekezeka kulimbikitsa kukula kwa msika wamagetsi a graphite.Zoposa 50% zazitsulo zomwe zimapangidwa padziko lonse lapansi zimagwiritsidwa ntchito pomanga ndi zomangamanga.Lipotilo limaphatikizapo madalaivala, zopinga, mwayi, ndi zomwe zachitika posachedwa zomwe zathandizira kukula kwa msika panthawi yowunikira.Lipotilo likusanthula mwatsatanetsatane mitundu ndi ntchito za magawo a zigawo.
graphite elekitirodi ndi mmodzi wa kondakitala, ndipo ndi mbali yofunika kwambiri pa ndondomeko steelmaking.Pochita izi, chitsulo chachitsulo chimasungunuka mu ng'anjo yamagetsi yamagetsi ndikusinthidwanso.Elekitirodi ya graphite mkati mwa ng'anjoyo inasungunuladi chitsulocho.Graphite imakhala ndi matenthedwe apamwamba kwambiri, ndipo imakhala ndi kutentha kwambiri komanso kugonjetsedwa.Ili ndi kukana kochepa, zomwe zikutanthauza kuti imatha kuyendetsa mafunde akulu omwe amafunikira kusungunula chitsulo.Graphite electrode imagwiritsidwa ntchito kwambiri mu ng'anjo yamagetsi yamagetsi (EAF) ndi ng'anjo ya ladle (LF) popanga zitsulo, ferroalloy, silicon metal graphite elekitirodi imagwiritsidwa ntchito mu ng'anjo yamagetsi yamagetsi (EAF) ndi ng'anjo ya ladle (LF) popanga zitsulo, kupanga ferroalloy, silicon metal Production ndi smelting process
Lipoti la msika wapadziko lonse wa graphite electrode limakhudza osewera odziwika bwino monga GrafTech, Fangda Carbon China, SGL Carbon Germany, Showa Denko, Graphite India, HEG India, Tokai Carbon Japan, Nippon Carbon Japan, SEC Carbon Japan, ndi zina zotero American GrafTech, Fangda Carbon China ndi Graphite India ali ndi mphamvu yokwanira yopanga matani 454,000.
