Chifukwa cha magwiridwe antchito abwino kwambiri a ma elekitirodi a graphite, kuphatikiza kukhathamiritsa kwakukulu, kukana kugwedezeka kwamafuta ndi dzimbiri lamankhwala komanso kutsika kodetsedwa, ma elekitirodi a graphite akugwira ntchito yofunika kwambiri pakupanga zitsulo za EAF pamakampani amakono azitsulo ndi zitsulo pofuna kuwongolera bwino, kuchepetsa ndalama, komanso kulimbikitsa. kukhazikika.
Kodi Graphite Electrode Ndi Chiyani?
GRAPHITE ELECTRODES ndi zinthu zabwino kwambiri zopangira ng'anjo yamagetsi yamagetsi ndi ng'anjo yosungunula, Amapangidwa ndi singano zamtengo wapatali zosakaniza, zoumba, zophikidwa ndi graphitization kuti apange mankhwala omalizidwa. Imatha kupirira kutentha kwambiri popanda kuphwanyidwa.Pakali pano ndi chinthu chokhacho chomwe chili ndi mphamvu zamagetsi zamagetsi komanso kuthekera kosunga kutentha kwakukulu komwe kumapangidwa m'malo ovuta.
Izi zimachepetsa kutayika kwa mphamvu ndikuwongolera njira yonse yosungunulira, zomwe zimapangitsa kuti magetsi asagwiritsidwe ntchito komanso kuchepetsa ndalama zopangira.
Ma Graphite Electrode Unique Properties
GRAPHITE ELECTRODE ndi yabwino kuti igwiritsidwe ntchito mu ng'anjo zamagetsi zamagetsi ndi ntchito zina za mafakitale.Makhalidwe apadera amaonetsetsa kuti electrode ya graphite imatha kupirira kutentha kwambiri kufika ku 3,000 ° C ndi kupanikizika mu ng'anjo yamagetsi yamagetsi (EAF).
- High Thermal Conductivity- Ma electrode a graphite ali ndi matenthedwe abwino kwambiri, omwe amawathandiza kuti athe kupirira kutentha komanso kupanikizika panthawi yosungunuka.
- Kukanika kwa Magetsi Otsika- Kutsika kwamagetsi kwamagetsi a graphite electrode kumathandizira kuyenda kosavuta kwa mphamvu zamagetsi mu ng'anjo yamagetsi yamagetsi.
- Mphamvu Zapamwamba Zamakina- Ma electrode a graphite adapangidwa kuti akhale ndi mphamvu zamakina apamwamba kuti athe kupirira kutentha kwambiri komanso kupanikizika m'ng'anjo zamagetsi zamagetsi.
- Kukaniza Kwabwino Kwambiri kwa Chemical- Graphite ndi chinthu chopanda mphamvu kwambiri chomwe chimagonjetsedwa ndi mankhwala ambiri ndi zinthu zowononga.Maelekitirodi a graphite abwino kuti agwiritsidwe ntchito m'malo ovuta a mafakitale, pomwe zida zina zitha kulephera chifukwa cha kuukira kwamankhwala.
Maelekitirodi a graphite samangogwiritsidwa ntchito kwambiri m'ng'anjo zamagetsi zamagetsi, amagwiritsidwanso ntchito popanga chitsulo cha silicon, phosphorous yachikasu, ndi zitsulo zina zopanda chitsulo, ma acid, alkalis, ndi mankhwala ena, malo owononga.
Maelekitirodi a graphite amagawidwa m'makalasi atatu kutengera momwe amagwirira ntchito, mawonekedwe ake ndi ntchito zosiyanasiyana zokhudzana ndi mphamvu yang'anjo yamagetsi, mphamvu yamagetsi yamagetsi.Ma elekitirodi a graphite omwe amagwiritsidwa ntchito kwambiri ndi Ultra-high power (UHP), High power (HP), ndi Regular power (RP).
UHP graphite maelekitirodi amakhala mkulu matenthedwe madutsidwe ndi kukana otsika magetsi, iwo makamaka ntchito kopitilira muyeso mphamvu magetsi arc ng'anjo (EAF) mu kusungunula zitsulo woyengedwa kapena wapadera steel.UHP graphite elekitirodi ndi oyenera mphamvu magetsi ng'anjo ndi 500~1200kV/ A pa tani.
HP Graphite Electrode ndiye chinthu chabwino kwambiri chopangira ng'anjo yamagetsi yamagetsi ndi ng'anjo yosungunula, imagwira ntchito ngati chonyamulira kuti ilowetse ng'anjo yamakono.HP graphite elekitirodi nthawi zambiri imagwiritsidwa ntchito ngati ng'anjo yamagetsi yamagetsi yamagetsi yamagetsi (EAF) yomwe mphamvu imakhala mozungulira 400kV/A. pa tani.
RP graphite elekitirodi imagwiritsidwa ntchito kwambiri mung'anjo yamagetsi yamagetsi yomwe mphamvu imakhala yozungulira 300kV / A pa tani kapena kuchepera. Gulu la RP lili ndi matenthedwe otsika kwambiri komanso mphamvu zamakina poyerekeza ndi UHP graphite electrode ndi HP graphite electrode.RP graphite electrode ndi oyenera kwambiri popanga zitsulo zotsika kwambiri monga zitsulo, kuyenga silicon, kuyenga phosphorous yachikasu, kupanga mafakitale agalasi.
Pakuchulukirachulukira kwa magwero amagetsi ena, ma elekitirodi a graphite akugwiranso ntchito yofunika kwambiri pakupanga ma cell amafuta.
Ma electrode a graphite ali ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana.Zina mwazomwe zimagwiritsidwa ntchito pamagetsi a graphite ndi monga;
Electric Arc Furnace (EAF) mu Kupanga Zitsulo
Kugwiritsa ntchito graphite electrode mu EAF steelmaking ndi gawo lofunikira pakupanga zitsulo zamakono.Maelekitirodi a graphite ali ngati kondakitala kuti apereke magetsi ku ng'anjo, yomwe imatulutsa kutentha kuti isungunuke zitsulo.Njira ya EAF imafuna kutentha kwakukulu kuti isungunuke zitsulo zowonongeka, ma electrode a graphite amatha kupirira kutentha kwambiri popanda kutaya kukhulupirika kwawo. akupitiriza kuganizira njira zisathe ndi imayenera kupanga, maelekitirodi graphite adzapitiriza kuchita mbali yofunika kwambiri EAF steelmaking.
Ladle Furnace (LF)
Ladle ng'anjo (LFs) ndi zigawo zofunika kwambiri pakupanga zitsulo Process.Graphite maelekitirodi ntchito ladle ng'anjo makampani kupereka apamwamba magetsi panopa ndi kutentha mkulu nthawi yonseyi.Ma elekitirodi a graphite ali ndi zinthu zabwino kwambiri kuphatikiza kukhathamiritsa kwakukulu, kukana kugwedezeka kwamafuta ndi dzimbiri lamankhwala, komanso moyo wautali, ndiye chisankho chabwino pakugwiritsa ntchito kwa ng'anjo ya ladle (LF). ndi zotsika mtengo, ndikusunga miyezo yapamwamba yomwe makampani amafuna.
Ng'anjo yamagetsi ya Submerged Electric (SEF)
Ma electrode a graphite amagwiritsidwa ntchito kwambiri mung'anjo yamagetsi yomira ndi chinthu chofunikira kwambiri popanga zitsulo ndi zinthu zambiri monga phosphorous yachikasu, silicon yoyera.Ma elekitirodi a graphite ali ndi mawonekedwe abwino kwambiri kuphatikiza kukhathamiritsa kwamagetsi kwambiri, kukana kwambiri kugwedezeka kwamafuta, komanso kutsika kwapakati pakukulitsa kwamafuta.Zinthuzi zimapangitsa kuti ma elekitirodi a graphite akhale abwino kuti agwiritsidwe ntchito m'ng'anjo zamagetsi zomwe zili pansi pamadzi, komwe kumakhala kutentha kwambiri komanso zovuta kwambiri.
Ma elekitirodi a graphite ndi zinthu zofunika kwambiri pakupanga zitsulo za Electric Arc Furnace (EAF). Ma elekitirodi a graphite amawononga mtengo wofunikira popanga zitsulo.
- Mtundu wachitsulo ndi kalasi
- Zowotcha ndi oxygen kuchita
- Mphamvu mlingo
- Mlingo wapano
- Kupanga ng'anjo ndi mphamvu
- Malipiro zinthu
- Kugwiritsa ntchito ma electrode a graphite
Kusankha ma elekitirodi oyenerera a graphite m'ng'anjo yanu ndikofunikira kuti mugwire bwino ntchito, kuchepetsa kugwiritsa ntchito mphamvu, komanso kuchepetsa ndalama zokonzera.
