Ma electrode e graphite anoshanda sei?

Ngatitaurei nezve ma electrode e graphite anoshanda sei? Maitiro ekugadzira ma electrode e graphite uye Nei ma electrode e graphite achifanira kutsiviwa?
1. Maelectrode egirafiti anoshanda sei?
Maelectrode acho chikamu chechivharo chechoto uye anounganidzwa kuita makoramu. Magetsi anobva apinda nemaelectrode, ogadzira arc yekupisa kwakanyanya inonyungudutsa simbi yakachekwa.
Maelectrode anotamiswa pasi pazvimedu munguva yekunyunguduka. Zvadaro arc inogadzirwa pakati peelectrode nesimbi. Nekufunga nezvekudzivirira, voltage yakaderera inosarudzwa nokuda kweizvi. Mushure mekunge arc yadzivirirwa nemaelectrode, voltage inowedzerwa kuti kukurumidze kunyunguduka.
2. Maitiro ekugadzira graphite electrode
Electrode yegrafiti inogadzirwa zvakanyanya nepetroleum coke ne needle coke, uye bitumen yemarasha inoshandiswa se binder. Inogadzirwa ne calcination, compounding, kneading, pressing, roasting, graphitization uye machining. Inoshandiswa kuburitsa simba remagetsi muchimiro che electric arc furnace. Conductor inopisa nekunyungudutsa chaji inogona kukamurwa kuita common power graphite electrode, high power graphite electrode uye ultra high power graphite electrode zvichienderana ne quality index yayo.

3. Sei ma electrode e graphite achifanira kutsiviwa?
Zvichienderana nemutemo wekushandiswa, pane zvikonzero zvakawanda zvekutsiva ma electrodes e graphite.
• Kushandiswa kwekupedzisira: Izvi zvinosanganisira sublimation yezvinhu zvegraphite zvinokonzerwa nekupisa kwakanyanya kwe arc uye kurasikirwa kwemakemikari pakati pe electrode nesimbi yakanyungudutswa uye slag. Kupisa kwakanyanya kwe sublimation kumagumo kunonyanya kuenderana nehuwandu hwemazuva ano hunopfuura nepakati pe electrode; zvakare hune hukama nedhayamita yerutivi rwe electrode mushure mekuoxidation; Kushandiswa kwekupedzisira kunoenderanawo nekuti electrode inofanira kuiswa mumvura yesimbi here kuti iwedzere kabhoni.
• Kuoxidation kwedivi: Kuumbwa kwemakemikari eelectrode icarbon, Kabhoni inooxidation nemhepo, utsi hwemvura uye kabhoni dioxide pasi pemamwe mamiriro, uye huwandu hweoxidation hwedivi reelectrode hunoenderana nehuwandu hweoxidation uye nzvimbo yekubuda. Kazhinji, oxidation yedivi reElectrode inokwana 50% yekushandiswa kweelectrode yese. Mumakore achangopfuura, kuitira kuvandudza kumhanya kwekunyungudutsa kwechoto chemagetsi, frequency yekushanda kweokisijeni inoputika inowedzera, kurasikirwa kweoxidation kweelectrode kunowedzera.
• Kurasikirwa kwasara: Kana electrode ichishandiswa nguva dzose panosangana ma electrode epamusoro neapasi, chikamu chidiki che electrode kana joint chinobviswa nekuda kwekutetepa kwe oxidative kwemuviri kana kupinda kwemakatsemuka.
• Kubviswa kwebvudzi pamusoro: Mugumisiro wekusagadzikana kwekupisa kweelectrode pachayo panguva yekunyungudutsa. Inosanganisira muviri weelectrode wakatyoka uye nipple yakatyoka. Kutyoka kweelectrode kunoenderana nemhando uye kugadzirwa kwegraphite electrode uye nipple, zvakare zvine chekuita nekushanda kwekugadzira simbi.
