Ama-electrode e-graphiteziyizingxenye ezibalulekile ekusebenzeni kwezithando zama-arc, ezidlala indima ebalulekile ezinqubweni eziningi zezimboni.
1. Isingeniso se-Graphite Electrodes:
Ama-electrode e-graphite ama-conductive rods enziwe ngezinto ze-graphite.Zisebenza njengama-conductor of current kagesi ezithandweni zikagesi ze-arc, lapho zingaphansi kwamazinga okushisa aphezulu nezimo ezinzima.Ngenxa yekhono lawo lokumelana namazinga okushisa aphakeme nokumelana nokuhlaselwa ngamakhemikhali, ama-electrode e-graphite abe amathuluzi abalulekile ezinhlelweni ezimbalwa eziyisisekelo zezimboni.
2. Ukubunjwa Nesakhiwo:
Ama-electrode e-graphite akhiwa ngokuyinhloko nge-petroleum coke, inaliti ye-coke, ne-coal tar pitch.I-petroleum coke isebenza njengempahla eluhlaza eyinhloko, ihlinzeka ngesisekelo se-carbon yama-electrode.I-needle coke, ene-thermal conductivity ephezulu kanye nezindawo ezinwebekayo eziphansi, isetshenziselwa ukuthuthukisa amandla emishini yama-electrode kanye nokuhamba kukagesi.Okokugcina, ukuphakama kwetiyela yamalahle kusebenza njenge-ejenti ebophayo ebamba ingxube ndawonye ngesikhathi sokukhiqiza, iqinisekisa ubuqotho besakhiwo sama-electrode.
3.I-Graphite Electrode Manufacturing Process:
Ukukhiqizwa kwama-electrode e-graphite kuhilela izigaba eziningana, kuqala ngokukhethwa nokuchotshozwa kwezinto zokusetshenziswa.Izinto ezisetshenziswayo zibe sezixutshwa futhi zihlanganiswe ukuze kuzuzwe ukwakheka okufunayo.Ngemuva kokuxuba, ingxube ewumphumela ibunjwa ibe yizimo ze-cylindrical ngokusebenzisa izinqubo zokucindezela noma ezikhiphayo.Ama-electrode abunjiwe abe eseshiselwa ezithandweni zokubhaka ukuze asuse izingxenye eziguquguqukayo futhi athuthukise ukuminyana kwazo.Ekugcineni, ama-electrode abhakiwe enza inqubo ye-graphitization lapho eshiselwa khona kumazinga okushisa angaphezu kuka-2500 degrees Celsius ukuze athuthukise ukuhamba kwawo kukagesi.
4. I-Graphite Electrode Properties:
Ama-electrode e-graphite anezinto ezimbalwa ezibalulekile eziwenza afanelekele kakhulu ukusetshenziswa kwawo.I-conductivity yabo kagesi ephezulu iqinisekisa ukukhiqizwa kokushisa okuphumelelayo ngaphakathi kwesithando somlilo se-arc, okuvumela izinqubo zokuncibilika nokucwenga.Ukwengeza, ama-electrode e-graphite abonisa ukumelana nokushaqeka okuhle kakhulu okushisayo, okubenza bakwazi ukumelana nokuguquguquka okukhulu kwezinga lokushisa ngaphandle kokuqhekeka.Ukungangeni kwabo kwamakhemikhali nokumelana nokuguguleka kubenza bakwazi ukumelana nezimo ezinzima kanye nokusabela kwamakhemikhali okukhona kuma-arc furnaces.
5. Izicelo:
Ama-electrode e-graphite athola ukusetshenziswa ezinqubweni ezihlukahlukene zezimboni, ikakhulukazi embonini yokwenza insimbi.Asetshenziswa ezithandweni zikagesi ze-arc ukukhiqizwa kwensimbi ne-alloy, lapho ancibilikisa izinsalela zensimbi futhi aziguqule zibe yinsimbi esebenzisekayo.Ama-electrode e-graphite nawo asetshenziswa ezithandweni ze-ladle ukuze kucwengwe insimbi futhi kulungiswe ukwakheka kwayo.Ngaphezu kwalokho, lawa ma-electrode adlala indima ebalulekile ekukhiqizweni kwe-silicon, i-phosphorous, ne-calcium carbide, kanye nasekukhiqizeni izinsimbi ezihlukahlukene.
6. Izinhlobo zama-Graphite Electrodes:
Ama-electrode e-graphite eza ngosayizi namabanga ahlukahlukene ukuze abhekane nezidingo zezimboni ezahlukene.Amandla aphezulu kakhulu (UHP) ama-graphite electrodezenzelwe izithando zama-arc ezinamandla amakhulu kanye nokukhiqizwa kwensimbi ngezinga elikhulu.Amandla aphezulu (HP) ama-graphite electrode afanele ukukhiqizwa kwensimbi, kuyilapho amandla avamile (RP) ama-graphite electrode evame ukusetshenziswa kuma-arc amancane naseziko anezidingo zamandla aphansi.
7. Ukubaluleka Kuzilungiselelo Zezimboni:
Ama-electrode e-graphite ayizingxenye ezibalulekile embonini yensimbi, njengoba enza ukuba kukhiqizwe insimbi yekhwalithi ephezulu ngendlela engabizi futhi ephumelelayo.Ukusetshenziswa kwazo kuma-arc furnaces kuvumela ukugaywa kabusha kwezinsalela zensimbi kanye nokunciphisa ukusetshenziswa kwamandla.Ngaphezu kwalokho, ama-electrode e-graphite aneqhaza ekusimameni okuphelele kokukhiqizwa kwensimbi ngokunciphisa ukukhishwa kwegesi ebamba ukushisa kanye nokunciphisa ukulahlwa kwemfucuza.
Ama-electrode e-graphite ayizingxenye ezibalulekile ezithandweni ze-arc, ezivumela izinqubo zezimboni ezifana nokukhiqizwa kwensimbi nokucwengwa kwensimbi.Izakhiwo zabo ezibalulekile, njengokuhamba kahle kukagesi, ukumelana nokushaqeka okushisayo, nokumelana nokuguguleka, kubenza bafaneleke kakhulu kulezi zinhlelo zokusebenza ezinzima.Indima yesithando somlilo se-arcabakhiqizi be-graphite electrodekubalulekile ekuqinisekiseni ukuhlinzekwa kwama-electrode ekhwalithi ephezulu ahlangabezana nezidingo ezithile zezimboni ezahlukene.Njengoba imboni yensimbi iqhubeka nokuvela, imizamo yocwaningo nentuthuko ekukhiqizeni i-graphite electrode izofaka isandla ekuthuthukisweni okuqhubekayo nasekusimameni kwezinqubo zezimboni.
