Graphite electrodeszvinhu zvakakosha mukushanda kwearc furnaces, zvichiita basa rakakosha mumaindasitiri akasiyana siyana.
Graphite electrodes inonyanya kugadzirwa kubva kumhando yekabhoni inonzi graphite, iyo iri crystalline fomu ye element element carbon.Graphite ine yakasarudzika midziyo inoita kuti ive yakakodzera kushandiswa muma electrode, senge yakakwira magetsi conductivity, kupikisa kwakanyanya kupisa uye makemikari, uye yakaderera coefficient yekuwedzera kwekupisa.Izvi zvivakwa zvinogonesa magraphite electrode kuti aite zvakasarudzika muarc vira rekushandisa.
Thegraphite electrodes kugadzira maitirokunosanganisira matanho akawanda.Inotanga nekusarudzwa kwemhando yepamusoro yegirafu zvinhu, izvo zvino zvino pasi uye zvakasanganiswa nebinder zvinhu, zvakadai semarasha tar pitch kana petroleum coke.Musanganiswa uyu unobva waumbwa kuita yaidiwa electrode fomu uchishandisa molding process.Mushure mekuumbwa, ma electrode anoiswa pasi pekubikira kubvisa binder uye kuwedzera kusimbisa iyo kabhoni chimiro.Izvi zvinoteverwa nemaitiro egraphitization, ayo anosanganisira kudziyisa maelectrodes kusvika kumatembiricha anosvika 3000 degrees Celsius kuti ashandure kuita graphite.Pakupedzisira, ma electrode anoenda kutevedzana kwemhando yekudzora bvunzo kuti ive nechokwadi chekuita kwavo uye kuvimbika.
Graphite electrode inowana mashandisirwo akakura mumaindasitiri akasiyana siyana, kunyanya mumagetsi arc furnaces.Aya mavira anoshandiswa kugadzirwa kwesimbi, uko ma graphite electrode anoshanda se conductive zvinhu kugadzira uye kuchengetedza arc yemagetsi, iyo inonyungudutsa mbishi zvinhu uye inobvumira kuumbwa kwesimbi yakanyungudutswa.Pamusoro pezvo, magirafu emagetsi anoshandiswa mune mamwe maitiro esimbi sekugadzirwa kweferroalloys, silicon simbi, uye calcium carbide.
Kukosha kwema graphite electrode muzvigadzirwa zveindasitiri hazvigone kuwedzeredzwa.Kupisa kwavo kwepamusoro kunobvumira kufambisa kupisa kwakanaka, kugonesa kukurumidza uye kwakanyatso kunyungudika kwezvinhu mumavira arc.Graphite electrodes inoratidzawo kupikisa kwakanyanya kunotyisa kutyisa, kuvadzivirira kubva pakutsemuka kana kutyora pasi pemamiriro ekushisa kwakanyanya.Uku kusimba kunochengetedza hupenyu hurefu hwe electrode uye kunoderedza kuderera uye mari yekugadzirisa.
Uyezve, thegraphite electrodes magetsi conductivitychimwe chinhu chakakosha mukukosha kwavo kwemaindasitiri.Iyo yakakwirira conductivity inogonesa kufamba kwakanaka kwemagetsi kuburikidza nemagetsi, zvichiita kuti arc yakagadzikana uye inopindirana panguva yekunyunguduka.Izvi zvinovimbisa yunifomu uye inodzorwa kugoverwa kwekupisa, zvichiita kuti kuve nekuvandudzwa kwesimbi uye kusagadzikana.
Saizi uye mhando yemagraphite electrode inokanganisa zvakanyanya kuita kwavo mukushanda kwearc furnace.Zviyero zvemagetsi, senge dhayamita uye kureba, zvinosiyana zvichienderana neyakagadzirirwa dhizaini uye zvinodiwa zvekugadzira.Vagadziri vanogadzira huwandu hwakasiyana hwehukuru hwe electrode kuti vagadzirise marudzi akasiyana echoto uye hunyanzvi.
Vagadziri ve graphite electrodeskuita basa rakakosha mukupa zvinhu izvi zvakakosha kumaindasitiri pasi rese.Vagadziri ava vanofanirwa kuomerera kune akasimba emhando yekudzora matanho kuti ave nechokwadi chekugadzirwa kwemaelectrode anoenderana neindasitiri zviyero.Kudzora kwemhando kunosanganisira bvunzo dzezvivakwa zvemuviri, senge density uye kuwedzera kwemafuta, pamwe nemagetsi zvivakwa, seresistivity uye yakanangana nemagetsi kuramba.Nekuchengetedza mazinga anowirirana emhando, vagadziri ve graphite electrode vanobatsira mukubudirira kwese uye kugadzirwa kwearc vira mashandiro.
Mukupedzisa, ma graphite electrode akakosha mukushanda kwearc furnaces uye anoita basa rakakosha mune akawanda maindasitiri maitiro.Zvimiro zvavo zvakasarudzika, senge yakakwira magetsi conductivity, kupisa kwekupisa, uye kusimba, inoita kuti ive yakakodzera kushandiswa mune izvi zvikumbiro.Maitiro ekugadzira magirafu emagetsi anosanganisira kusarudzwa kwemhando yepamusoro-soro, inoteverwa nenhevedzano yematanho senge kusanganisa, kuumba, kubheka, uye graphitization.Graphite electrodes inowana mashandisirwo mukugadzirwa kwesimbi uye akasiyana siyana metallurgical process.Kukosha kwavo kuri mukukwanisa kwavo kufambisa kupisa zvakanaka, kuramba kupisa kwekushisa, uye kupa kugadzikana kwemagetsi conductivity.Pakazere, vagadziri ve graphite electrode vanoita basa rakakosha mukupa emhando yepamusoro maelectrode uye kuve nechokwadi chekushanda uye kuvimbika kwekushanda kwemaindasitiri.
TAURA NESUKUTI RUZIVO RAKARWARA PAMUSORO PE GRAPHITE ELECTRODES.
