Asebenza kanjani ama-electrode e-graphite?

Ake sixoxe ngokuthi Asebenza kanjani ama-electrode e-graphite?Inqubo yokukhiqiza i-graphite electrode futhi Kungani i-graphite electrode idinga ukushintshwa?
1. Asebenza kanjani ama-electrode e-graphite?
Ama-electrode ayingxenye yesivalo sesithando somlilo futhi ahlanganiswe abe amakholomu.Ugesi ube usudlula kuma-electrode, enze i-arc yokushisa okunamandla okuncibilikisa insimbi elahliwe.
Ama-electrode athuthelwa phansi phezu kwe-scrap ngesikhathi sokuncibilika.Khona-ke i-arc ikhiqizwa phakathi kwe-electrode nensimbi.Ngokucabangela isici sokuvikela, i-voltage ephansi ikhethwa kulokhu.Ngemuva kokuthi i-arc ivikelwe ngama-electrode, i-voltage iyanda ukuze kusheshiswe inqubo yokuncibilika.
2. inqubo yokukhiqiza i-graphite electrode
I-electrode ye-graphite yenziwe ngokuyinhloko nge-petroleum coke ne-needle coke, kanti i-bitumen yamalahle isetshenziswa njenge-binder.Yenziwa ngokubala, ukuhlanganisa, ukuxova, ukucindezela, ukugazinga, i-graphitization kanye nomshini.Iwukukhipha amandla kagesi ngendlela ye-arc kagesi esithandweni somlilo se-arc kagesi.I-conductor eshisisa futhi incibilike inkokhiso ingahlukaniswa ibe i-electrode yamandla e-graphite evamile, i-electrode enamandla amakhulu e-graphite kanye ne-ultra high power graphite electrode ngokuvumelana nenkomba yekhwalithi yayo.

3. Kungani ama-electrode e-graphite edinga ukushintshwa?
Ngokusho kwesimiso sokusetshenziswa, kunezizathu eziningana zokushintshwa kwama-electrode e-graphite.
• Ukuphela kokusetshenziswa: Lokhu kufaka phakathi ukuncibilika kwempahla yegraphite okubangelwa izinga lokushisa eliphezulu le-arc kanye nokulahlekelwa ukusabela kwamakhemikhali phakathi kwe-electrode nensimbi encibilikisiwe ne-slag.Izinga lokushisa eliphakeme lokuncishiswa kwe-sublimation ekugcineni lincike kakhulu ekumineni kwamanje okudlula ku-electrode;futhi ihlobene nobubanzi bohlangothi lwe-electrode ngemva kwe-oxidation;Ukusetshenziswa kokuphela kuphinde kuhlotshaniswe nokuthi i-electrode ingafakwa yini emanzini ensimbi ukuze kwandiswe ikhabhoni.
• I-Lateral oxidation: Ukwakheka kwamakhemikhali e-electrode yikhabhoni, Ikhabhoni izokhipha umoya, umhwamuko wamanzi kanye ne-carbon dioxide ngaphansi kwezimo ezithile, futhi inani le-oxidation lohlangothi lwe-electrode lihlobene nenani leyunithi ye-oxidation kanye nendawo yokuchayeka.Ngokuvamile, i-Electrode side oxidation Ibalelwa ku-50% wengqikithi yokusetshenziswa kwama-electrode.Eminyakeni yamuva, ukuze kuthuthukiswe isivinini sokuncibilika kwesithando somlilo kagesi, imvamisa yokusebenza kokuphefumula komoyampilo iyanda, ukulahleka kwe-oxidation kwe-electrode kuyanda.
• Ukulahleka kwensalela: Uma i-electrode isetshenziswa ngokuqhubekayo lapho kuhlangana khona ama-electrode angaphezulu nangaphansi, ingxenye encane ye-electrode noma ilunga liyahlukaniswa ngenxa yokuncipha kwe-oxidative yomzimba noma ukungena kwemifantu.
• Ukuxebuka nokuwa komphezulu: Umphumela wokungezwani kahle nokushaqeka okushisayo kwe-electrode ngokwayo ngesikhathi sokuncibilika.Kuhlanganisa nomzimba we-electrode ophukile kanye nengono ephukile.I-Electrode ephukile ihlobene nekhwalithi kanye nemishini ye-graphite electrode nengono, futhi ehlobene nokusebenza kokwenza insimbi.
