Ukusetshenziswa kwama-electrode e-graphite ezithandweni zikagesi ze-arc kungenye yezinto ezibalulekile zokuthuthukisa isikhathi sazo sokuphila nokusebenza kahle. Izithando zikagesi ze-arc, njengohlobo olubalulekile lwemishini yensimbi, zisetshenziswa kabanzi ezimbonini ezifana nensimbi nezinsimbi ezingezona ezensimbi. Umgomo wazo osebenzayo ukushisa nokuncibilikisa insimbi nge-arc kagesi eshisa kakhulu ekhiqizwa phakathi kwe-electrode kanye nokushaja. Ama-electrode e-graphite, ngenxa yezakhiwo zawo eziyingqayizivele zomzimba nezamakhemikhali, abonisa ukusebenza okuhle kakhulu ezithandweni zikagesi ze-arc, ngaleyo ndlela athuthukisa kakhulu impilo yesevisi yezithando zikagesi ze-arc. Okulandelayo ukuhlaziywa okuningiliziwe okuvela ezicini eziningi zokuthi ama-electrode e-graphite angathuthukisa kanjani isikhathi sokuphila sezithando zikagesi ze-arc.
1. Ukuqina kokushisa okuphezulu
I-Graphite inokumelana okuphezulu kakhulu nokushisa okuphezulu, kanye nephuzu lokuncibilika elifinyelela ku-3650℃, eliphakeme kakhulu kunephuzu lokuncibilika lezinsimbi eziningi kanye nama-alloy. Esithandweni se-arc kagesi, ama-electrode kudingeka amelane nokushisa okuphezulu okufika ku-3000℃, kodwa ama-electrode e-graphite asakwazi ukugcina izakhiwo zomzimba nezamakhemikhali ezizinzile ngaphansi kwezimo ezimbi kangaka. Ngokuphambene nalokho, ama-electrode enziwe ngezinye izinto avame ukuthamba, ukuwohloka noma ukuncibilika emazingeni okushisa aphezulu, okuholela esikhathini sokuphila se-electrode esifushane. Ukuqina kokushisa okuphezulu kwe-graphite electrode kuqinisekisa ukuthi ayonakaliswa kalula endaweni yokusebenza emazingeni okushisa aphezulu isikhathi eside, ngaleyo ndlela kwandise impilo yenkonzo iyonke yesithando se-arc kagesi.
2. Ukuqhuba kahle kukagesi
Ugesi we-graphite unomoya omuhle kakhulu kagesi, onokumelana okuphansi kanye nekhono lokuqhuba ugesi ngempumelelo. Esithandweni sikagesi se-arc, ama-electrode adinga ukuguqula amandla kagesi abe amandla okushisa. Isici sokumelana okuphansi kwama-electrode e-graphite sinciphisa ukulahleka kwamandla kagesi, ngaleyo ndlela sithuthukise ukusebenza kahle kwamandla. Ngaphezu kwalokho, ukumelana okuphansi kunciphisa nokushisa okukhiqizwa yi-electrode uqobo, kunciphisa ingozi yokulimala kwe-electrode ngenxa yokushisa ngokweqile. Umoya ophezulu kagesi awugcini nje ngokuthuthukisa ukusebenza kahle kwesithando sikagesi se-arc, kodwa futhi kunciphisa ukuguguleka kwama-electrode futhi kwandise impilo yawo yenkonzo.
3. Amandla amahle okusebenza ngomshini
I-arc kagesi ye-graphite inamandla aphezulu okusebenza futhi ingamelana nokucindezeleka kokusebenza kanye nokudlidliza okwenziwa ngesikhathi sokusebenza kwesithando somlilo se-arc kagesi. Esithandweni somlilo se-arc kagesi, ama-electrode kudingeka ahambe phezulu naphansi njalo ukuze alungise ubude be-arc, kuyilapho futhi kufanele amelane nokushaywa kanye nokucindezela kwensimbi encibilikisiwe ngaphakathi kwesithando somlilo. Amandla aphezulu kanye nokuqina kwama-electrode e-graphite kuwenza angaphuki kalula noma aguge ngaphansi kwezimo zokusebenza eziyinkimbinkimbi kangaka, ngaleyo ndlela kuncishiswe imvamisa yokufakwa esikhundleni kwe-electrode futhi kwandiswe impilo yenkonzo yama-arc omlilo kagesi.
4. Ukumelana nokushaqeka okushisayo
Izinga lokushisa lendawo yokusebenza lesithando sikagesi se-arc liyashintsha kakhulu, futhi ama-electrode kudingeka avame ukudlula inqubo yokupholisa ngokushesha kusukela ekushiseni okuphezulu kuya ekushiseni okuphansi. Ama-electrode e-graphite anokumelana okuhle kakhulu nokushaqeka kokushisa futhi angagcina ubuqotho besakhiwo lapho izinga lokushisa lishintsha kakhulu, futhi awakwazi ukuqhekeka noma ukulimala ngenxa yokucindezeleka kokushisa. Lesi sici senza i-electrode ye-graphite isebenze kahle isikhathi eside esithandweni sikagesi se-arc, kunciphisa ukwehluleka kwe-electrode okubangelwa ukushaqeka kokushisa, futhi ngaleyo ndlela kwandisa impilo yenkonzo iyonke yesithando sikagesi se-arc.
5. Ukumelana namakhemikhali
Esithandweni se-arc kagesi, ama-electrode ahlangana nama-oxide ensimbi ahlukahlukene, i-slag nezinye izinto zamakhemikhali. Ama-electrode e-graphite anokumelana okuhle kakhulu nokugqwala kwamakhemikhali futhi angamelana nokuguguleka kwama-asidi amaningi, ama-alkali nama-oxide. Lesi sici senza ama-electrode e-graphite angathinteki kakhulu ekugqwaleni noma ekugqwaleni ezindaweni zamakhemikhali ezinzima, ngaleyo ndlela anciphise ukuguguleka kwama-electrode futhi andise isikhathi sawo sokusebenza.
6. I-coefficient ephansi yokwanda kokushisa
I-coefficient yokwanda kokushisa kwama-electrode e-graphite iphansi kakhulu, okusho ukuthi izinguquko zazo zobukhulu zincane emazingeni okushisa aphezulu. I-coefficient ephansi yokwanda kokushisa yenza i-electrode ye-graphite ingabi namathuba amaningi okubangela ukugxilisa ingqondo noma ukuguqulwa ngenxa yokwanda kokushisa ezindaweni zokusebenza ezishisa kakhulu, ngaleyo ndlela kunciphisa ingozi yokulimala kwe-electrode. Lesi sici senza i-electrode ye-graphite ihlale izinzile ngesikhathi sokusebenza kwesikhathi eside kwezinga lokushisa eliphezulu, ngaleyo ndlela yandisa impilo yenkonzo yesithando somlilo se-arc kagesi.
7. Indawo ezigcoba ngayo
I-Graphite inezakhiwo zokuzigcoba futhi inganciphisa ukungqubuzana nezinye izingxenye emazingeni okushisa aphezulu. Lesi sici senza ukuhamba kwama-electrode e-graphite ezithandweni zikagesi ze-arc kube lula, kunciphisa ukuguguleka kanye nomonakalo obangelwa ukungqubuzana. Impahla yokuzigcoba ayigcini nje ngokwandisa impilo yesevisi yama-electrode kodwa futhi inciphisa izindleko zokugcinwa kwama-arc omlilo kagesi.
8. Ubungane bemvelo
Ama-electrode e-graphite akhiqiza ukungcola okuncane ngesikhathi sokukhiqizwa nokusetshenziswa, futhi kulula ukuwasebenzisa kabusha. Lokhu kusebenzelana kwemvelo akugcini nje ngokuhlangabezana nezidingo zentuthuko esimeme yezimboni zanamuhla, kodwa futhi kunciphisa umonakalo wemishini kanye nokunciphisa isikhathi sokuphila esibangelwa ukungcola kwemvelo.
Isiphetho
Ekuphetheni, ama-electrode e-graphite abonisa ukusebenza okuvelele kuma-arc furnace kagesi ngenxa yokuqina kwawo okushisa okuphezulu, ukuhanjiswa kukagesi okuhle kakhulu, amandla amahle okusebenza, ukumelana nokushaqeka kokushisa, ukumelana nokugqwala kwamakhemikhali, i-coefficient ephansi yokwanda kokushisa, ukuzigcoba, kanye nobungane bemvelo. Lezi zici azigcini nje ngokuthuthukisa ukusebenza kahle kanye nesilinganiso sokusetshenziswa kwamandla kwesithando somlilo se-arc kagesi, kodwa futhi zandisa kakhulu impilo yaso yesevisi. Ngakho-ke, ama-electrode e-graphite abe yizinto ezibalulekile ezisetshenziswa kuma-arc furnace kagesi, enikeza ukwesekwa okubalulekile ekuthuthukisweni kwemboni yesimanje yensimbi.
