Ama-electrode e-graphite asebenza kanjani?

Ake sixoxe ngokuthi Asebenza kanjani ama-electrode e-graphite? Inqubo yokukhiqiza ama-electrode e-graphite nokuthi Kungani ama-electrode e-graphite edinga ukushintshwa?
1. Ama-electrode e-graphite asebenza kanjani?
Ama-electrode ayingxenye yesivalo sesithando futhi ahlanganiswa abe amakholomu. Ugesi ube usudlula kuma-electrode, wakhe umugqa wokushisa okukhulu oncibilikisa insimbi elahliwe.
Ama-electrode athuthelwa phansi e-scrap ngesikhathi sokuncibilika. Bese i-arc ikhiqizwa phakathi kwe-electrode nensimbi. Ngokucabangela isici sokuvikela, kukhethwa i-voltage ephansi yalokhu. Ngemva kokuba i-arc ivikelwe ama-electrode, i-voltage iyandiswa ukuze kusheshiswe inqubo yokuncibilika.
2. inqubo yokukhiqiza i-graphite electrode
I-electrode ye-graphite yenziwe kakhulu nge-petroleum coke kanye ne-needle coke, kanti i-bitumen yamalahle isetshenziswa njenge-binder. Yenziwa ngokugaya, ukuhlanganisa, ukuxova, ukucindezela, ukuthosa, i-graphitization kanye nomshini wokugaya. Iwukukhipha amandla kagesi ngesimo se-arc kagesi esithandweni se-arc kagesi. Umqhubi ofudumeza futhi ancibilikise ishaja angahlukaniswa abe yi-electrode ye-graphite enamandla avamile, i-electrode ye-graphite enamandla aphezulu kanye ne-electrode ye-graphite enamandla aphezulu ngokwezinga layo.

3. Kungani ama-electrode e-graphite edinga ukushintshwa?
Ngokomgomo wokusetshenziswa, kunezizathu eziningana zokufaka esikhundleni sama-electrode e-graphite.
• Ukusetshenziswa kokugcina: Lokhu kufaka phakathi i-sublimation yezinto ze-graphite ezibangelwa ukushisa okuphezulu kwe-arc kanye nokulahleka kokusabela kwamakhemikhali phakathi kwe-electrode nensimbi encibilikisiwe kanye ne-slag. Izinga lokunciphisa izinga lokushisa eliphezulu ekugcineni lincike kakhulu ekuxineni kwamanje okudlula ku-electrode; futhi kuhlobene nobubanzi bohlangothi lwe-electrode ngemva kwe-oxidation; Ukusetshenziswa kokugcina kuhlobene nokuthi kufanele yini kufakwe i-electrode emanzini ensimbi ukuze kwandiswe ikhabhoni.
• Ukushiswa kwe-lateral: Ukwakheka kwamakhemikhali kwe-electrode yi-carbon, i-Carbon izoshiswa ngomoya, umhwamuko wamanzi kanye ne-carbon dioxide ngaphansi kwezimo ezithile, futhi inani lokushiswa kwe-electrode ohlangothini lwe-electrode lihlobene nesilinganiso sokushiswa kweyunithi kanye nendawo yokuchayeka. Ngokuvamile, ukushiswa kwe-electrode ohlangothini lwe-electrode kubalelwa cishe ku-50% wokusetshenziswa kwe-electrode iyonke. Eminyakeni yamuva nje, ukuze kuthuthukiswe isivinini sokuncibilikisa sesithando sikagesi, imvamisa yokusebenza kokuvunguza komoya-mpilo iyakhula, ukulahleka kwe-oxidation kwe-electrode kuyanda.
• Ukulahleka kwensalela: Uma i-electrode isetshenziswa njalo lapho kuhlangana khona ama-electrode aphezulu naphansi, ingxenye encane ye-electrode noma ijoyinti iyahlukaniswa ngenxa yokuncipha kwe-oxidative komzimba noma ukungena kwemifantu.
• Ukuxebuka nokuwa komphezulu: Umphumela wokumelana nokushaqeka okungekuhle kokushisa kwe-electrode uqobo ngesikhathi senqubo yokuncibilikisa. Faka phakathi umzimba we-electrode ophukile kanye ne-nipple ephukile. Ukuqhekeka kwe-electrode kuhlobene nekhwalithi kanye nokucutshungulwa kwe-graphite electrode kanye ne-nipple, futhi kuhlobene nokusebenza kokwenziwa kwensimbi.
