550mm mkulu mphamvu graphite elekitirodi
HP graphite elekitirodi makamaka zopangidwa mafuta coke ndi singano coke, Iwo amatha kunyamula osalimba panopa 18-25A/cm2. Amapangidwa kuti azipanga zitsulo zamphamvu kwambiri zamagetsi arc ng'anjo.
Njira zamakono zopangira zitsulo makamaka zimaphatikizapo kutembenuza zitsulo ndi zitsulo zamagetsi zamagetsi. Kusiyanitsa kwakukulu pakati pa njira yopangira zitsulo zamagetsi ndi njira yosinthira zitsulo ndi njira yopangira zitsulo zamagetsi pogwiritsa ntchito mphamvu yamagetsi monga gwero la kutentha, ndipo njira yopangira zitsulo za arc ng'anjo ndiyo yomwe imagwiritsidwa ntchito kwambiri.
EAF steelmaking imachokera ku arc yamagetsi yopangidwa ndi kutulutsa pakati pa elekitirodi ndi chiwongolero, chomwe chimasintha mphamvu yamagetsi kukhala mphamvu yotentha mu kuwala kwa arc, ndikugwiritsa ntchito njira yachindunji ya radiation ndi arc kutentha ndikusungunula zitsulo ndi slag kuti zisungunuke. zitsulo ndi aloyi a nyimbo zosiyanasiyana.

Ma electrode a graphite
1.Petroleum coke ndi wakuda ndi porous, carbon ndiye chigawo chachikulu, ndipo phulusa ndilochepa kwambiri, nthawi zambiri pansi pa 0.5%.
Petroleum coke akhoza kugawidwa mu mitundu iwiri ya coke yaiwisi ndi calcined coke malinga ndi kutentha kutentha mankhwala. Zakale zimakhala ndi zinthu zambiri zowonongeka ndipo zimakhala ndi mphamvu zochepa zamakina. The calcined coke imapezeka mwa calcining yaiwisi coke.
Mafuta a coke amatha kugawidwa mu sulfure coke yapamwamba (yomwe ili ndi sulfure pamwamba pa 1.5%), coke ya sulfure yapakati (yokhala ndi sulfure 0.5% -1.5%), ndi coke ya sulfure yochepa (yokhala ndi sulfure pansi pa 0.5%) malinga ndi mlingo wa sulfure. Ma electrode a graphite ndi zinthu zina zopangira ma graphite nthawi zambiri amapangidwa pogwiritsa ntchito coke yotsika ya sulfure.
2.Needle coke ndi mtundu wa coke wapamwamba kwambiri wokhala ndi mawonekedwe owoneka bwino a ulusi, makamaka kutsika kwamafuta owonjezera kowonjezera komanso graphitization yosavuta. Chifukwa chake, coke ya singano ndi chinthu chofunikira kwambiri popanga ma elekitirodi amphamvu kwambiri kapena opitilira mphamvu kwambiri a graphite omwe amawonetsedwa ndi kutsika kochepa, kocheperako pang'ono kwamafuta, komanso kukana kugwedezeka kwamafuta.
3.Coal pitch ndi imodzi mwazinthu zazikulu za phula lamalasha pambuyo pokonza kwambiri. Ndi chisakanizo cha ma hydrocarbon angapo. Mafuta a malasha amagwiritsidwa ntchito ngati chomangira komanso chopangira mimba. Kuchita kwake kumakhudza kwambiri khalidwe la ma electrode a graphite.
