Kawirikawiri, busbar pakati pa mapeto otuluka a DC graphitization furnace rectifier cabinet ndi conductive electrode ya mutu wa furnace imatchedwa short net, ndipo busbar yomwe imagwiritsidwa ntchito mu graphitization furnace nthawi zambiri imakhala yamakona anayi. Busbar ya graphitization furnace imapangidwa ndi mkuwa ndi aluminiyamu. Mkuwa uli ndi mphamvu zambiri zamakaniko, mphamvu zamagetsi zabwino komanso kukana dzimbiri mwamphamvu. Aluminiyamu ndi yochepa pang'ono, koma aluminiyamu ndi yotsika mtengo ndipo ndi yopepuka.
Gome 3-2 Deta yogwirizana ndi magwiridwe antchito a mkuwa ndi aluminiyamu

Popeza kukana kwa ng'anjo ya graphitization ndi kochepa, makamaka kumapeto kwa nthawi yotumizira mphamvu, kukana kwa ng'anjo kumakhala kochepa, ndipo kutsika kwa kuthamanga kwa ukonde waufupi kumawonjezeka, zomwe zimapangitsa kuti mphamvu iwonongeke kwambiri. Chifukwa chake, kaya ng'anjo ya graphitization ingagwire ntchito mosamala komanso mopanda ndalama ili ndi ubale wapafupi ndi makhalidwe a ukonde waufupi.
Mfundo yofunika kwambiri ndi kuchepetsa kuponderezedwa kwa ukonde waufupi ndikusunga ukonde wonse waufupi ndi kutsika pang'ono kwa kupanikizika. Pali zolumikizira zosiyanasiyana mu ukonde waufupi wa graphitization. Ngati pali kukhudzana pakati pa elekitirodi yoyendetsa ndi basi yamkuwa, kukhudzana pakati pa basi yofewa yamkuwa ndi basi ya aluminiyamu, kukhudzana pakati pa basi ya aluminiyamu, ndi zina zotero, zolumikizirazi zipanga kukana kwa kukhudzana, zomwe zimakhudza mawonekedwe a ukonde wonse waufupi. Kukana kwa kukhudzana kwa kondakitala wokhala ndi malo olumikizira sikudalira kokha mtundu wa zinthuzo, komanso malo olumikizirana ndi kupsinjika kwa kukhudzana panthawi yolumikizirana. Pachifukwa ichi, chofunikira kwambiri polumikiza mabasi ndi: kupukuta kumakhala kolimba.
Gome 3-3 Kukana kukhudzana kwa graphite ya 1cm2 ndi chitsulo cha 1cm2
