Kufotokozera Kwachidule:

Ma electrode a graphite amagwiritsidwa ntchito pa ng'anjo zamagetsi za arc, ng'anjo za ladle ndi ng'anjo za arc zonyowa pansi pa nthaka. Pambuyo popatsidwa mphamvu mu EAF steelmaking, Monga conductor wabwino, amagwiritsidwa ntchito kupanga arc, ndipo kutentha kwa arc kumagwiritsidwa ntchito kusungunula ndi kuyeretsa chitsulo, zitsulo zopanda ferrous ndi alloys zawo. Ndi conductor wabwino wamagetsi mu ng'anjo yamagetsi ya arc, sichisungunuka ndi kusokonekera kutentha kwambiri, ndipo chimasunga mphamvu inayake yamakina. Pali mitundu itatu:RP,HPndiElectrode ya graphite ya UHP.

Kodi electrode ya graphite ndi chiyani?

Ma electrode a grafiti amagwiritsidwa ntchito makamaka pa ng'anjo zamagetsi ndi ng'anjo zotenthetsera ndi zoteteza pansi pa madzi ngati conductor wabwino. Pa mtengo wopanga zitsulo za ng'anjo zamagetsi, kugwiritsa ntchito ma electrode a grafiti kumakhala pafupifupi 10%.

Yapangidwa ndi petroleum coke ndi pitch coke, ndipo ma grade amphamvu kwambiri komanso amphamvu kwambiri amapangidwa ndi needle coke. Ali ndi phulusa lochepa, mphamvu zamagetsi zabwino, kutentha, komanso kukana dzimbiri, ndipo sasungunuka kapena kusokonekera kutentha kwambiri.

Zokhudza magiredi ndi ma diameter a ma electrode a graphite a graphite.

JINSUN ili ndi magiredi ndi ma diameter osiyanasiyana. Mutha kusankha magiredi a RP, HP kapena UHP, omwe angakuthandizeni kukonza magwiridwe antchito a ng'anjo yamagetsi, kuwonjezera magwiridwe antchito, komanso kuwonjezera phindu lazachuma. Tili ndi ma diameter osiyanasiyana, 150mm-700mm, omwe angagwiritsidwe ntchito posungunula ma ng'anjo yamagetsi ya matani osiyanasiyana.

Kusankha bwino mtundu ndi kukula kwa ma electrode n'kofunika kwambiri. Izi zithandiza kwambiri kuonetsetsa kuti chitsulo chosungunukacho chili bwino komanso kuti ng'anjo yamagetsi ya arc igwire ntchito bwino.

Kodi imagwira ntchito bwanji popanga zitsulo za eaf?

Magetsi a graphite amalowetsa mphamvu yamagetsi mu ng'anjo yopanga zitsulo, yomwe ndi njira yopangira zitsulo ya ng'anjo yamagetsi ya arc. Mphamvu yamagetsi yamphamvu imatumizidwa kuchokera ku transformer ya ng'anjo kudzera mu chingwe kupita ku chogwirira kumapeto kwa mikono itatu ya electrode ndikulowamo.

Chifukwa chake, pakati pa mapeto a electrode ndi chaji, arc discharge imachitika, ndipo chaji imayamba kusungunuka pogwiritsa ntchito kutentha komwe kumapangidwa ndi arc ndipo chaji imayamba kusungunuka. Malinga ndi mphamvu ya ng'anjo yamagetsi, wopanga adzasankha ma diameter osiyanasiyana kuti agwiritse ntchito.

Kuti tigwiritse ntchito ma electrode mosalekeza panthawi yosungunulira, timalumikiza ma electrode kudzera m'ma nipple okhala ndi ulusi. Popeza gawo lopingasa la nipple ndi laling'ono kuposa la electrode, nipple iyenera kukhala ndi mphamvu yopondereza komanso yocheperako kuposa electrode.

Kuphatikiza apo, pali makulidwe ndi magiredi osiyanasiyana, kutengera momwe amagwiritsidwira ntchito komanso zofunikira pakupanga zitsulo za eaf.
