Ma electrode a graphitendi zigawo zofunika kwambiri pakugwira ntchito kwa ng'anjo za arc, zomwe zimagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana.
Ma electrode a graphite amapangidwa makamaka kuchokera kumtundu wa carbon wotchedwa graphite, womwe ndi mawonekedwe a crystalline a element element carbon.Graphite ali ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mu maelekitirodi, monga kukhathamiritsa kwake kwamagetsi, kukana kutentha ndi mankhwala, komanso kutsika kwamphamvu kwamafuta.Zinthu izi zimathandiza kuti ma electrode a graphite azigwira bwino ntchito mu ng'anjo ya arc.
Thegraphite electrode kupanga ndondomekoimaphatikizapo njira zingapo.Zimayamba ndi kusankha zipangizo zamtengo wapatali za graphite, zomwe kenaka amazipukuta ndi kusakaniza ndi zinthu zomangira, monga phula la malasha kapena petroleum coke.Kusakaniza kumeneku kumapangidwira mu mawonekedwe omwe amafunidwa a electrode pogwiritsa ntchito njira yopangira.Pambuyo poumba, ma electrode amapangidwa ndi njira yophika kuti achotse binder ndikulimbikitsanso mpweya wa carbon.Izi zimatsatiridwa ndi ndondomeko ya graphitization, yomwe imaphatikizapo kutentha ma elekitirodi ku kutentha kwa pafupifupi madigiri 3000 Celsius kuti asandutse graphite.Pomaliza, ma elekitirodi amakumana ndi mayeso angapo owongolera kuti atsimikizire momwe amagwirira ntchito komanso kudalirika.
Ma electrode a graphite amapeza ntchito zambiri m'njira zosiyanasiyana zamafakitale, makamaka m'ng'anjo zamagetsi zamagetsi.ng'anjo zimenezi ntchito kupanga zitsulo, kumene maelekitirodi graphite ntchito conductive zipangizo kupanga ndi kusunga arc magetsi, amene amasungunula zopangira ndi kulola kuti mapangidwe chitsulo chosungunuka.Kuphatikiza apo, ma elekitirodi a graphite amagwiritsidwa ntchito munjira zina zazitsulo monga kupanga ferroalloys, chitsulo cha silicon, ndi calcium carbide.
Kufunika kwa maelekitirodi a graphite m'mafakitale sikungatheke.Kutentha kwawo kwakukulu kumapangitsa kuti kutentha kutheke bwino, kumapangitsa kuti zinthu zisungunuke mwachangu komanso molondola kwambiri mu ng'anjo za arc.Ma electrode a graphite amawonetsanso kukana kwamphamvu kwa kutentha, kuwalepheretsa kusweka kapena kusweka ndi kutentha kwambiri.Kukhazikika kumeneku kumapangitsa moyo wautali wa ma elekitirodi ndikuchepetsa nthawi yochepetsera komanso kukonzanso.
Komanso, agraphite maelekitirodi magetsi madutsidwendi chinthu chinanso chofunikira pakufunika kwawo kwamakampani.Kuthamanga kwapamwamba kumapangitsa kuti magetsi aziyenda bwino kudzera mumagetsi, zomwe zimapangitsa kuti pakhale phokoso lokhazikika komanso lokhazikika panthawi yosungunuka.Izi zimatsimikizira kugawidwa kwa yunifolomu ndi kulamulidwa kwa kutentha, zomwe zimapangitsa kuti zitsulo zikhale bwino komanso zisagwirizane.
Kukula ndi mtundu wa ma elekitirodi a graphite zimakhudza kwambiri momwe amagwirira ntchito mu ng'anjo ya arc.Miyeso ya maelekitirodi, monga m'mimba mwake ndi kutalika kwake, imasiyana malinga ndi momwe ng'anjo imapangidwira komanso zofunikira zopangira.Opanga amapanga ma elekitirodi osiyanasiyana kuti athe kutengera mitundu yosiyanasiyana ya ng'anjo ndi mphamvu.
Opanga ma electrode a graphitezimagwira ntchito yofunika kwambiri popereka zinthu zofunikazi kumakampani padziko lonse lapansi.Opanga awa ayenera kutsatira njira zowongolera zowongolera kuti awonetsetse kupanga ma elekitirodi omwe amakwaniritsa miyezo yamakampani.Kuwongolera kwaubwino kumaphatikizapo kuyesa zinthu zakuthupi, monga kachulukidwe ndi kufutukuka kwamafuta, komanso mphamvu zamagetsi, monga resistivity ndi kukana kwina kwamagetsi.Pokhala ndi mikhalidwe yosasinthika, opanga ma elekitirodi a graphite amathandizira kuti magwiridwe antchito azing'onoting'ono a arc azitha kugwira ntchito bwino komanso kutulutsa bwino.
Pomaliza, ma electrode a graphite ndi ofunikira pakugwira ntchito kwa ng'anjo za arc ndipo amatenga gawo lofunikira pamakina ambiri amakampani.Makhalidwe awo apadera, monga kupangika kwamphamvu kwamagetsi, kukana kwamafuta, komanso kulimba, zimawapangitsa kukhala abwino kuti agwiritsidwe ntchito pazinthu izi.Kapangidwe ka ma electrode a graphite kumaphatikizapo kusankha mosamala zida za graphite zapamwamba, zotsatiridwa ndi masitepe angapo monga kusakaniza, kuumba, kuphika, ndi graphitization.Ma electrode a graphite amapeza ntchito pakupanga zitsulo komanso njira zosiyanasiyana zazitsulo.Kufunika kwawo kwagona pakutha kusamutsa bwino kutentha, kukana kugwedezeka kwamafuta, komanso kupereka mphamvu yokhazikika yamagetsi.Ponseponse, opanga ma elekitirodi a graphite amatenga gawo lofunikira popereka ma elekitirodi apamwamba kwambiri ndikuwonetsetsa kuti ntchito zamafakitale ndi zodalirika komanso zodalirika.
LUMIKIZANANI NAFEKUDZIWA ZOYENERA ZA MA ELECTRODE A GRAPHITE.
