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.
