Kugwiritsa ntchito ma electrode a graphite mu ng'anjo zamagetsi ndi chimodzi mwazinthu zofunika kwambiri pakukweza moyo wawo komanso magwiridwe antchito awo. Ma ng'anjo zamagetsi, monga mtundu wofunikira wa zida zachitsulo, amagwiritsidwa ntchito kwambiri m'mafakitale monga zitsulo ndi zitsulo zopanda chitsulo. Mfundo yake yogwirira ntchito ndikutenthetsa ndikusungunula chitsulo kudzera mu arc yamagetsi yotentha kwambiri yomwe imapangidwa pakati pa electrode ndi mphamvu. Ma electrode a graphite, chifukwa cha mawonekedwe awo apadera komanso a mankhwala, amasonyeza magwiridwe antchito abwino kwambiri mu ng'anjo zamagetsi zamagetsi, motero amawonjezera kwambiri moyo wa ntchito ya ng'anjo zamagetsi zamagetsi. Zotsatirazi ndi kusanthula kwatsatanetsatane kuchokera mbali zosiyanasiyana za momwe ma electrode a graphite angakulitsire moyo wa ng'anjo zamagetsi zamagetsi.
1. Kukhazikika kwa kutentha kwambiri
Graphite ili ndi mphamvu yolimba kwambiri pa kutentha, ndipo malo osungunuka amafika pa 3650℃, zomwe ndi zapamwamba kwambiri kuposa malo osungunuka a zitsulo ndi alloys ambiri. Mu ng'anjo yamagetsi, ma electrode amafunika kupirira kutentha kofika pa 3000℃, komabe ma electrode a graphite amatha kukhalabe ndi mphamvu zokhazikika zakuthupi ndi zamakemikolo pansi pa mikhalidwe yovuta kwambiri yotere. Mosiyana ndi zimenezi, ma electrode opangidwa ndi zinthu zina amakonda kufewa, kusinthasintha kapena kusungunuka kutentha kwambiri, zomwe zimapangitsa kuti nthawi ya electrode ikhale yochepa. Kukhazikika kwa kutentha kwambiri kwa graphite electrode kumatsimikizira kuti sikuwonongeka mosavuta pamalo ogwirira ntchito otentha kwambiri kwa nthawi yayitali, motero kumawonjezera moyo wonse wa ng'anjo yamagetsi.
2. Kuyendetsa bwino magetsi
Magetsi a graphite ali ndi mphamvu yabwino kwambiri yoyendetsera magetsi, yokhala ndi mphamvu yochepa yolimbana ndi magetsi komanso mphamvu yoyendetsa magetsi bwino. Mu ng'anjo yamagetsi ya arc, ma electrode amafunika kusintha mphamvu zamagetsi kukhala mphamvu yotentha. Kukana kochepa kwa ma electrode a graphite kumachepetsa kutayika kwa mphamvu zamagetsi, motero kumawonjezera kugwiritsa ntchito mphamvu moyenera. Kuphatikiza apo, kukana kochepa kumachepetsanso kutentha komwe kumapangidwa ndi electrode yokha, kuchepetsa chiopsezo cha kuwonongeka kwa ma electrode chifukwa cha kutentha kwambiri. Kuthamanga kwambiri kwamagetsi sikuti kumangowonjezera kugwira ntchito bwino kwa ng'anjo yamagetsi ya arc, komanso kumachepetsa kutopa kwa ma electrode ndikuwonjezera moyo wawo wautumiki.
3. Mphamvu yabwino yamakina
Chitoliro chamagetsi cha graphite chili ndi mphamvu zambiri zamakina ndipo chimatha kupirira kupsinjika kwamakina ndi kugwedezeka komwe kumachitika panthawi yogwira ntchito ya ng'anjo yamagetsi. Mu ng'anjo yamagetsi ya arc, ma electrode amafunika kusuntha mmwamba ndi pansi pafupipafupi kuti asinthe kutalika kwa chitoliro, komanso kupirira kukhudzidwa ndi kukakamizidwa kwa chitsulo chosungunuka mkati mwa ng'anjo. Mphamvu yayikulu ndi kulimba kwa ma electrode a graphite zimapangitsa kuti asasweke kapena kusweka mosavuta pansi pa zovuta zotere, motero amachepetsa kuchuluka kwa kusintha kwa ma electrode ndikuwonjezera moyo wa ntchito ya zitoliro zamagetsi za arc.
4. Kukana kutentha kwa kutentha
Kutentha kwa malo ogwirira ntchito a ng'anjo yamagetsi ya arc kumasintha kwambiri, ndipo ma electrode amafunika kuzizira mofulumira nthawi zambiri kuyambira kutentha kwambiri mpaka kutentha kochepa. Ma electrode a graphite ali ndi mphamvu yabwino kwambiri yolimbana ndi kutentha ndipo amatha kusunga mawonekedwe ake pamene kutentha kumasintha kwambiri, ndipo sachedwa kusweka kapena kuwonongeka chifukwa cha kutentha. Khalidweli limalola electrode ya graphite kugwira ntchito mokhazikika kwa nthawi yayitali mu ng'anjo yamagetsi ya arc, amachepetsa kulephera kwa electrode komwe kumachitika chifukwa cha kutentha, ndipo motero amawonjezera moyo wonse wa ng'anjo yamagetsi ya arc.
5. Kukana mankhwala
Mu uvuni wamagetsi, ma electrode amakumana ndi ma oxide achitsulo osiyanasiyana, slag ndi mankhwala ena. Ma electrode a grafiti ali ndi kukana kwabwino kwa mankhwala ndipo amatha kukana kuwonongeka kwa ma acid ambiri, alkali ndi ma oxide. Khalidweli limapangitsa ma electrode a grafiti kukhala osavutikira ndi dzimbiri kapena oxidation m'malo ovuta a mankhwala, motero amachepetsa kuwonongeka kwa ma electrode ndikuwonjezera nthawi yawo yogwira ntchito.
6. Kuchuluka kwa kutentha kotsika
Kuchuluka kwa kutentha kwa ma electrode a graphite ndi kochepa, zomwe zikutanthauza kuti kusintha kwawo kwa miyeso kumakhala kochepa kutentha kwambiri. Kuchuluka kochepa kwa kutentha kumapangitsa kuti electrode ya graphite isayambitse kupsinjika kapena kusintha kwa kutentha chifukwa cha kutentha kwambiri m'malo ogwirira ntchito otentha kwambiri, motero kuchepetsa chiopsezo cha kuwonongeka kwa electrode. Khalidweli limalola electrode ya graphite kukhala yokhazikika panthawi yogwira ntchito yotentha kwambiri kwa nthawi yayitali, motero imakulitsa moyo wautumiki wa ng'anjo yamagetsi.
7. Malo odzipaka mafuta okha
Graphite ili ndi mphamvu zodzipaka yokha ndipo imatha kuchepetsa kukangana ndi zinthu zina kutentha kwambiri. Khalidweli limapangitsa kuti kuyenda kwa ma electrode a graphite m'zitofu zamagetsi kukhale kosalala, zomwe zimachepetsa kuwonongeka ndi kuwonongeka komwe kumachitika chifukwa cha kukangana. Katundu wodzipaka yekha samangowonjezera nthawi yogwira ntchito ya ma electrode komanso amachepetsa ndalama zosamalira zitofu zamagetsi zamagetsi.
8. Kusamalira chilengedwe
Ma electrode a graphite amapanga zinthu zochepa zoipitsa chilengedwe popanga ndi kugwiritsa ntchito, ndipo ndi osavuta kubwezeretsanso. Kusamalira chilengedwe kumeneku sikungokwaniritsa zofunikira pakukula kokhazikika kwa mafakitale amakono, komanso kumachepetsa kuwonongeka kwa zida ndi kufupikitsa nthawi yogwira ntchito chifukwa cha kuipitsa chilengedwe.
Mapeto
Pomaliza, ma electrode a graphite amasonyeza bwino kwambiri mu ng'anjo zamagetsi chifukwa cha kukhazikika kwawo kutentha kwambiri, kuyendetsa bwino magetsi, mphamvu yabwino yamakina, kukana kutentha, kukana dzimbiri kwa mankhwala, kukulitsa kutentha pang'ono, kudzipaka mafuta okha, komanso kusamala chilengedwe. Makhalidwe amenewa samangowonjezera mphamvu yogwira ntchito komanso kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito mu ng'anjo zamagetsi, komanso amawonjezera kwambiri moyo wake wautumiki. Chifukwa chake, ma electrode a graphite akhala zinthu zofunika kwambiri mu ng'anjo zamagetsi, zomwe zimapereka chithandizo chofunikira pakukula kwa makampani amakono a zitsulo.
