Kune mhando dzakasiyana dzekabhoni uye graphite electrode zvigadzirwa, zvinoenderana nekushandiswa kwavo kwakasiyana, kune zvakakosha zvekushandisa zvinodiwa uye mhando zviratidzo.Patinenge tichifunga kuti ndeupi rudzi rwezvigadzirwa zvinofanira kushandiswa kune chimwe chigadzirwa, tinofanira kutanga tadzidza kuti tingasangana sei nezvinodiwa izvi zvakakosha uye zviratidzo zvehutano.
(1) Kusarudzwa kwezvinhu zvakasvibirira zvekuitisa graphite electrode inoshandiswa mu electrometallurgical process senge EAF steelmaking.
Iyo conductive graphite electrode inoshandiswa mu electrometallurgical process senge EAF steelmaking inofanirwa kuve neyakanaka conductivity, kwakaringana simba remagetsi, kumira zvakanaka kudzima uye kudziyisa pakupisa kwepamusoro, kushomeka kwecorrosion uye kuderera kwehutsvina.
① Yemhando yepamusoro magirafu emagetsi anogadzirwa kubva petroleum coke, pitch coke uye zvimwe zvakaderera madota zvinhu.Nekudaro, kugadzirwa kwe graphite electrode kunoda mimwe michina, kuyerera kwenguva refu uye tekinoroji yakaoma, uye kushandiswa kwesimba kwe1 t graphite electrode i6000 ~ 7000 kW · H.
② Yakakwira mhando anthracite kana metallurgical coke inoshandiswa seyakabikwa kugadzira kabhoni electrode.Kugadzirwa kwekabhoni electrode hakudi graphitization michina, uye mamwe maitiro ekugadzira akafanana nekugadzirwa kwegraphite electrode.Iyo conductivity yekabhoni electrode yakaipisisa kupfuura iyo yegraphite electrode.Iyo resistivity yecarbon electrode inowanzokwira 2-3 nguva yakakwira kupfuura iyo yegraphite electrode.Madota emukati anosiyana nemhando yezvigadzirwa, iyo inenge 10%.Asi mushure mekuchenesa kwakakosha, madota e anthracite anogona kuderedzwa kusvika pasi pe5%.Madota emukati echigadzirwa anogona kuderedzwa kusvika anenge 1.0% kana chigadzirwa chikawedzera graphitized.Carbon electrode inogona kushandiswa kunyungudutsa zvakajairika EAF simbi uye ferroalloy
③ Kushandisa yakasikwa graphite seyakagadzirwa, yakasikwa graphite electrode yakagadzirwa.Natural graphite inogona kushandiswa chete mushure mekunyatsosarudzwa uye madota ayo akaderedzwa.The resistivity of natural graphite electrode ingangoita kaviri iyo graphitized electrode.Asi simba remuchina rakaderera, nyore kutyora kana uchishandisa.Munzvimbo ine akawanda echisikigo graphite kugadzirwa, yakasikwa graphite electrode inogona kugadzirwa kuti ipe diki EAF kunyungudutsa yakajairika EAF simbi.Paunenge uchishandisa yakasikwa graphite kugadzira conductive electrode, midziyo uye tekinoroji zviri nyore kugadzirisa uye kugona.
④ Graphite electrode inoshandiswa kugadzira regenerated electrode (kana graphitized yakatyoka electrode) kuburikidza nekupwanya nekukuya kwekucheka marara kana tsvina.Iyo madota echigadzirwa haisi yakakwirira (inenge 1%), uye conductivity yayo yakaipisisa kupfuura iyo ye graphitized electrode.Resistivity yaro ingangoita ka1.5 yeiyo yemagetsi emagetsi, asi kushanda kwayo kuri nani pane kweiyo yemagetsi graphite electrode.Kunyangwe zviri nyore kugona tekinoroji uye midziyo yekugadzira yakagadziridzwa electrode, iyo mbishi sosi yegraphitization ishoma, saka iyi haisi iyo nzira yekusimudzira.
