Iielectrode zegraphitengamacandelo abalulekileyo ekusebenzeni kwee-arc furnaces, asebenza indima ebalulekileyo kwiinkqubo ezahlukeneyo zamashishini.
Iielectrode zegraphite zenziwe ngokuyintloko ngohlobo lwekhabhoni ebizwa ngokuba yigraphite, eluhlobo lwecrystalline lwe element carbon.Igraphite ineempawu ezizodwa ezenza ukuba ilungele ukusetyenziswa kwii-electrode, ezinje nge-conductivity ephezulu yombane, ukumelana nobushushu kunye neekhemikhali, kunye ne-coefficient ephantsi yokwanda kwe-thermal.Ezi zakhiwo zenza ukuba i-electrode yegraphite isebenze ngokugqwesileyo kwizicelo zesithando somlilo se-arc.
IInkqubo yokuvelisa i-graphite electrodeibandakanya amanyathelo aliqela.Iqala ngokukhethwa kwezinto eziphezulu zegraphite, ezithi emva koko zicolwe kwaye zixutywe kunye nezinto ezibophayo, ezifana ne-tar pitch yamalahle okanye i-petroleum coke.Lo mxube umiliselwe kwifomu ye-electrode efunwayo usebenzisa inkqubo yokubumba.Emva kokubumba, i-electrodes iphantsi kwenkqubo yokubhaka ukususa i-binder kunye nokuqinisa ngakumbi isakhiwo sekhabhoni.Oku kulandelwa yinkqubo yegraphitization, equka ukufudumeza i-electrode ukuya kumaqondo obushushu amalunga nama-3000 ngokukaCelsius ukuziguqula zibe yigraphite.Ekugqibeleni, i-electrode idlula uluhlu lweemvavanyo zokulawula umgangatho ukuqinisekisa ukusebenza kwabo kunye nokuthembeka.
I-electrode yegraphite ifumana ukusetyenziswa okubanzi kwiinkqubo ezahlukeneyo zemizi-mveliso, ngakumbi kwii-arc zombane zombane.Ezi zixhobo zisetyenziselwa ukuveliswa kwentsimbi, apho i-electrode yegraphite isebenza njengezinto zokuqhuba ukuvelisa nokugcina i-arc yombane, enyibilikisa izinto eziluhlaza kwaye ivumela ukubunjwa kwesinyithi esityhidiweyo.Ukongeza, ii-electrode zegraphite zisetyenziswa kwezinye iinkqubo zetsimbi ezifana nokuveliswa kweeferroalloys, isinyithi sesilicon, kunye ne-calcium carbide.
Ukubaluleka kwee-electrode zegraphite kwiindawo zoshishino azikwazi ukugqithiswa.I-conductivity yabo ephezulu ye-thermal ivumela ukuhanjiswa kobushushu ngokufanelekileyo, okwenza ukunyibilika ngokukhawuleza kunye nokuchaneka ngakumbi kwezinto eziphathekayo kwii-arc furnaces.Iielectrode zegraphite zikwabonisa ukuxhathisa okugqwesileyo kumothuko we-thermal, ukuthintela ukuqhekeka okanye ukwaphuka phantsi kweemeko zobushushu obugqithisileyo.Oku kuqina kuqinisekisa ubomi obude be-electrode kwaye kunciphisa ixesha lokuphumla kunye neendleko zokugcina.
Ngaphezu koko, iigraphite electrode conductivity yombaneyenye into ebalulekileyo ekubalulekeni kwabo kwezoshishino.I-conductivity ephezulu yenza ukuhamba kakuhle kombane ngokusebenzisa i-electrodes, okubangela ukuba i-arc ezinzile kunye ne-arc ngexesha lokunyibilika.Oku kuqinisekisa ukuhanjiswa okufanayo kunye nokulawulwa kokushisa, okukhokelela ekuphuculeni umgangatho wensimbi kunye nokuhambelana.
Ubungakanani kunye nomgangatho wee-electrode zegraphite zichaphazela kakhulu ukusebenza kwazo kwi-arc furnace operations.Imilinganiselo yee-electrodes, ezifana nobubanzi kunye nobude bayo, iyahluka ngokuxhomekeka kuyilo oluthile lwesithando somlilo kunye neemfuno zokuvelisa.Abavelisi bavelisa uluhlu olubanzi lobungakanani be-electrode ukulungiselela iintlobo ezahlukeneyo zesithando somlilo kunye nobuchule.
Abavelisi bee-electrode zegraphiteidlala indima ebalulekileyo ekuboneleleni ngezi nxalenye zibalulekileyo kumashishini ehlabathi jikelele.Aba bavelisi kufuneka babambelele kwimilinganiselo engqongqo yokulawula umgangatho wokuqinisekisa ukuveliswa kwee-electrode ezihlangabezana nemigangatho yoshishino.Ulawulo lomgangatho lubandakanya iimvavanyo zeempawu ezibonakalayo, ezifana nokuxinana kunye nokwandiswa kwe-thermal, kunye neempawu zombane, ezifana nokuxhathisa kunye nokuxhatshazwa kombane.Ngokugcina imigangatho yomgangatho ohambelanayo, abavelisi be-graphite electrode bafaka isandla ekusebenzeni kakuhle kunye nemveliso yemisebenzi yesithando somlilo we-arc.
Ukuqukumbela, ii-electrode zegraphite zibalulekile ekusebenzeni kwee-arc furnaces kwaye zidlala indima ebalulekileyo kwiinkqubo ezininzi zoshishino.Iimpawu zabo ezikhethekileyo, ezifana nokuhamba kombane ophezulu, ukuxhathisa i-thermal, kunye nokuqina, kubenza balungele ukusetyenziswa kwezi zicelo.Inkqubo yokwenziwa kwee-electrode zegraphite ibandakanya ukukhetha ngononophelo kwemathiriyeli yegraphite ekumgangatho ophezulu, elandelwa luthotho lwamanyathelo afana nokuxuba, ukubumba, ukubhaka, kunye negraphitization.I-electrode yegraphite ifumana izicelo kwimveliso yentsimbi kunye neenkqubo ezahlukeneyo zetsimbi.Ukubaluleka kwabo kukwazi ukudlulisa ukushisa ngokufanelekileyo, ukuxhathisa ukutshitshiswa kwe-thermal, kunye nokubonelela nge-conductivity yombane ezinzileyo.Ngokubanzi, abavelisi be-electrode be-graphite badlala indima ebalulekileyo ekuboneleleni kwee-electrode ezikumgangatho ophezulu kunye nokuqinisekisa ukusebenza kakuhle kunye nokuthembeka kwemisebenzi yoshishino.
