Ma electrode a graphitendi gawo lofunikira pakupanga zitsulo, komwe amagwiritsidwa ntchito mu Electric Arc Furnaces (EAFs).Amagwiritsidwa ntchito makamaka popanga zitsulo komanso zitsulo zopanda chitsulo.M'zaka zaposachedwapa, kufunika kwama electrode a graphitechakula chifukwa cha kuchuluka kwa kufunikira kwa zinthu zachitsulo komanso kugogomezera kwambiri njira zopangira zitsulo zamagetsi.Kuchulukirachulukira kwa magalimoto amagetsi kwathandiziranso kukula kwa msika wama graphite electrode.
Msika wapadziko lonse wa Ultra-high power (UHP) ma graphite electrode akuyembekezeka kuchitira umboni kukula kwakukulu pazaka zingapo zikubwerazi chifukwa chakuchulukirachulukira kwa mafakitale omwe amagwiritsidwa ntchito kumapeto monga chitsulo, aluminiyamu, ndi silicon.Malinga ndi kafukufuku wamsika waposachedwa, msika wa UHP graphite electrode ukuyembekezeka kukhala woposa $ 500 miliyoni pofika 2029, ukukula pa CAGR ya 4.4% panthawi yolosera 2023-2029.
Kufunika kwa ma electrode a graphite a UHP kumayendetsedwa ndi kukwera kwa zitsulo, makamaka m'maiko omwe akutukuka kumene omwe ali ndi mafakitale omangamanga monga India ndi China.Kupanga zitsulo padziko lonse lapansi kudakwera 4.6% mu 2018 kufika matani biliyoni 1.81, malinga ndi World Steel Association.Makampani achitsulo ndi zitsulo ndiye msika waukulu kwambiri wogula ma elekitirodi okwera kwambiri a graphite, omwe amawerengera 80% yazofunikira zonse.
Kuphatikiza pamakampani opanga zitsulo, mafakitale a aluminiyamu ndi silicon ndiwonso ogula kwambiri ma electrode a graphite apamwamba kwambiri.Osungunula aluminiyamu amagwiritsa ntchito maelekitirodi kuti apange aluminiyamu, pamene makampani a silicon amawagwiritsa ntchito kupanga zitsulo za silicon.Pamene kufunikira kwa zitsulo izi kukuchulukirachulukira, kufunikira kwa ma elekitirodi a ultra-high purity graphite kukuyembekezekanso kuwonjezeka.
Mmodzi mwa otsogolera akuluakulu aUHP graphite electrodesmsika ndizomwe zikukula mu Electric Arc Furnaces (EAF) mumakampani azitsulo.Ma EAF ndi okonda zachilengedwe komanso otsika mtengo kuposa ng'anjo zachikale, ndipo ntchito yawo imafunikira ma elekitirodi apamwamba kwambiri a UHP graphite.Izi zapangitsa kuti pakhale kuwonjezeka kwakukulu kwa kufunikira kwa ma elekitirodi a ultra-high-purity graphite m'zaka zaposachedwa.
Chinanso chomwe chikuthandizira kukula kwa msika wamagetsi apamwamba kwambiri a graphite electrode ndikukula kwa mabatire ochita bwino kwambiri.Ma electrode a UHP graphite amagwiritsidwa ntchito popanga mabatire a lithiamu-ion, omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuchokera kumagetsi ogula mpaka magalimoto amagetsi.Chifukwa chakuchulukirachulukira kwa magalimoto amagetsi, kufunikira kwa ma elekitirodi a ultra-high purity graphite akuyembekezeka kuwonjezeka kwambiri m'zaka zikubwerazi.
Komabe, msika wa UHP graphite electrode umakumana ndi zovuta zingapo, kuphatikiza kupezeka kwa zida.Graphite ndi chinthu chofunikira kwambiri popanga ma elekitirodi amphamvu kwambiri a graphite, ndipo padziko lonse lapansi ma graphite apamwamba kwambiri ndi ochepa.Izi zapangitsa kuti pakhale zinthu zina monga singano coke, yomwe imagwiritsidwa ntchito m'malo mwa graphite popanga ma elekitirodi a graphite a UHP.
Vuto lina lomwe msika wa UHP graphite electrode ukukumana nalo ndikuwonjezera mpikisano kuchokera kuzinthu zina monga silicon carbide ndi carbon fiber.Zidazi zimapereka zinthu zofanana ndi ma elekitirodi a graphite a UHP pamtengo wotsika, zomwe zingakhudze kufunikira kwa ma elekitirodi a graphite a UHP.
Kuphatikiza apo, malamulo okhwima a maboma okhudzana ndi kutulutsa mpweya amatha kulepheretsa kukula kwa msika wa ma electrode a graphite, makamaka akamayang'ana kugwiritsa ntchito mpweya m'makampani azitsulo.Anthu osiyanasiyana ogwira nawo ntchito m'makampaniwa tsopano akugogomezera kufunika kwa kupanga zitsulo zobiriwira.Zotsatira zake, tikulimbikitsidwa kuti opanga aganizire zopanga ndalama muukadaulo wokonda zachilengedwe, zomwe zingapangitse kuti zinthu zawo ziwonekere kwa makasitomala.
Asia Pacific ndiye msika waukulu kwambiri wama elekitirodi okwera kwambiri a graphite, omwe amawerengera theka lazofunikira padziko lonse lapansi.China ndiye ogula kwambiri ma elekitirodi a graphite a UHP m'derali, ndikutsatiridwa ndi Japan ndi India.Kukwera kwachitsulo ku China ndi India kukuyembekezeka kuyendetsa kufunikira kwa ma elekitirodi a graphite a UHP m'zaka zikubwerazi.
North America ndi Europe ndiwonso misika yofunikira yama electrode a graphite apamwamba kwambiri, US, Germany, ndi UK ndi omwe amagula kwambiri.Kuchulukitsa kukhazikitsidwa kwa magalimoto amagetsi m'magawo awa kukuyembekezeka kuyendetsa kufunikira kwa ma electrode a UHP graphite popanga batire la lithiamu-ion.
Mwachidule, dziko lapansiUltra-high-purity graphite electrodesmsika ukuyembekezeka kuchitira umboni kukula kwakukulu pazaka zingapo zikubwerazi, motsogozedwa ndi kukwera kwa kuchuluka kwa mafakitale omwe amagwiritsidwa ntchito kumapeto monga zitsulo, aluminiyamu, silicon ndi mafakitale amagetsi amagetsi. kuchulukitsa mpikisano kuchokera kuzinthu zina, malamulo aboma okhudza kutulutsa mpweya wa kaboni, pakati pa ena.Osewera ofunikira pamsika akuyang'ana kwambiri maubwenzi ndi mgwirizano kuti awonjezere gawo lawo lamsika ndikuwongolera zomwe amapereka.
