Ukusetyenziswa kwee-electrode zegrafiti kwii-oven ze-arc zombane yenye yezinto eziphambili zokuphucula ubomi bazo kunye nokusebenza kwazo kakuhle. Ii-oven ze-arc zombane, njengohlobo olubalulekileyo lwezixhobo ze-metallurgical, zisetyenziswa kakhulu kumashishini afana nentsimbi kunye neentsimbi ezingezizo i-ferrous. Umgaqo wayo osebenzayo kukufudumala nokunyibilikisa isinyithi nge-arc yombane eshushu kakhulu eveliswa phakathi kwe-electrode kunye netshaja. Ii-electrode zegrafiti, ngenxa yeempawu zazo zomzimba nezekhemikhali ezizodwa, zibonisa ukusebenza okugqwesileyo kwii-oven ze-arc zombane, ngaloo ndlela ziphucula kakhulu ubomi benkonzo yee-oven ze-arc zombane. Oku kulandelayo luhlalutyo oluneenkcukacha oluvela kwiinkalo ezininzi malunga nendlela ii-electrode zegrafiti ezinokuphucula ngayo ubomi bee-oven ze-arc zombane.
1. Uzinzo lobushushu obuphezulu
I-Graphite inokumelana nobushushu obuphezulu kakhulu, kunye nendawo yokunyibilika ephezulu njenge-3650℃, ephezulu kakhulu kuneendawo zokunyibilika zesinyithi kunye nee-alloys ezininzi. Kwisithando sombane se-arc, ii-electrode kufuneka zimelane nobushushu obuphezulu obungaphezulu kwe-3000℃, kodwa ii-electrode ze-graphite zisenokugcina iipropati zomzimba nezekhemikhali ezizinzileyo phantsi kweemeko ezinzima kangaka. Ngokwahlukileyo koko, ii-electrode ezenziwe ngezinye izinto zidla ngokuthamba, ziguquguquke okanye zinyibilike kumaqondo obushushu aphezulu, nto leyo ebangela ukuba ubomi be-electrode bufutshane. Ukuzinza kobushushu obuphezulu kwe-graphite electrode kuqinisekisa ukuba ayonakaliswa lula kwindawo yokusebenza enobushushu obuphezulu bexesha elide, ngaloo ndlela yandisa ubomi benkonzo iyonke yesithando sombane se-arc.
2. Ukuqhuba kombane okugqwesileyo
Umbane wegrafiti une-conductivity egqwesileyo yombane, kunye ne-resistivity ephantsi kunye nokukwazi ukuqhuba umbane ngokufanelekileyo. Kwi-electrical arc furnace, ii-electrode kufuneka ziguqule amandla ombane abe ngamandla obushushu. Ukumelana okuphantsi kwe-graphite electrodes kunciphisa ukulahleka kwamandla ombane, ngaloo ndlela kuphucula ukusebenza kakuhle kwamandla. Ukongeza, ukumelana okuphantsi kunciphisa nobushushu obuveliswa yi-electrode ngokwayo, kunciphisa umngcipheko wokonakala kwe-electrode ngenxa yokushisa kakhulu. Ukuqhuba okuphezulu kombane akupheleli nje ekuphuculeni ukusebenza kakuhle kwe-electrical arc furnace, kodwa kunciphisa nokuguguleka kwee-electrode kwaye kwandisa ubomi bazo benkonzo.
3. Amandla oomatshini alungileyo
I-arc yombane ye-graphite inamandla aphezulu oomatshini kwaye inokumelana noxinzelelo loomatshini kunye nokungcangcazela okwenziwa ngexesha lokusebenza kwesithando sombane se-arc. Kwisithando sombane se-arc, ii-electrode kufuneka zinyuke zize zihle rhoqo ukuze zilungise ubude be-arc, ngelixa kufuneka zinyamezele impembelelo kunye noxinzelelo lwesinyithi esinyibilikisiweyo ngaphakathi kwesithando. Amandla aphezulu kunye nokuqina kwee-electrode ze-graphite kuzenza zingabi lula ukwaphuka okanye ukuguguleka phantsi kweemeko zokusebenza ezinzima kangaka, ngaloo ndlela kunciphisa ukuphindaphindeka kokutshintshwa kwe-electrode kwaye kwandise ubomi benkonzo yezithando zombane ze-arc.
4. Ukumelana noxinzelelo olushushu
Ubushushu bendawo yokusebenza ye-electric arc furnace butshintsha ngokukhawuleza, kwaye ii-electrode kufuneka zihlale ziphantsi kwenkqubo yokuphola ngokukhawuleza ukusuka kubushushu obuphezulu ukuya kubushushu obuphantsi. Ii-graphite electrodes zinokumelana okuhle kakhulu nokutshayiswa kobushushu kwaye zinokugcina ulungelelwaniso lwesakhiwo xa ubushushu butshintsha ngokukhawuleza, kwaye azinakukuqhekeka okanye zonakale ngenxa yoxinzelelo lobushushu. Olu phawu lwenza i-graphite electrode isebenze ngokuzinzileyo ixesha elide kwi-electric arc furnace, inciphisa ukusilela kwe-electrode okubangelwa kukutshayiswa kobushushu, kwaye ngaloo ndlela yonyusa ubomi benkonzo iyonke ye-electric arc furnace.
5. Ukumelana neekhemikhali
Kwisithando sombane esisebenza nge-arc, ii-electrode zidibana nee-oxides zesinyithi ezahlukeneyo, i-slag kunye nezinye izinto zeekhemikhali. Ii-electrode ze-graphite zinokumelana nokugqwala kweekhemikhali okuhle kakhulu kwaye zinokumelana nokugqwala kwee-asidi ezininzi, ii-alkalis kunye nee-oxides. Olu phawu lwenza ii-electrode ze-graphite zingabi sengozini yokugqwala okanye ukugqwala kwiindawo ezinoburhabaxa beekhemikhali, ngaloo ndlela zinciphisa ukuguguleka kwee-electrode kwaye zandise ubomi bazo benkonzo.
6. I-coefficient ephantsi yokwanda kobushushu
I-coefficient yokwandiswa kobushushu bee-electrode ze-graphite iphantsi kakhulu, nto leyo ethetha ukuba utshintsho lwazo lobukhulu luncinci xa kushushu kakhulu. I-coefficient ephantsi yokwandiswa kobushushu yenza ukuba i-electrode ye-graphite ingabi nokubangela uxinzelelo okanye ukuguqulwa ngenxa yokwanda kobushushu kwiindawo zokusebenza ezinobushushu obuphezulu, ngaloo ndlela kunciphisa umngcipheko wokonakala kwe-electrode. Olu phawu lwenza i-electrode ye-graphite ihlale izinzile ngexesha lokusebenza kobushushu obuphezulu ixesha elide, ngaloo ndlela yandisa ubomi benkonzo yesithando somlilo se-arc sombane.
7. Ipropati yokuzithambisa ngokwayo
I-Graphite ineempawu zokuzithambisa ngokwayo kwaye inokunciphisa ukungqubana nezinye izinto kubushushu obuphezulu. Olu phawu lwenza ukuhamba kwee-electrode ze-graphite kwii-oven zombane ze-arc kube lula, kunciphisa ukuguguleka kunye nomonakalo obangelwa kukungqubana. Ipropati yokuzithambisa ngokwayo ayigcini nje ngokwandisa ubomi benkonzo yee-electrode kodwa ikwanciphisa neendleko zokugcinwa kwee-oven zombane ze-arc.
8. Ubuhlobo nokusingqongileyo
Ii-electrode zegrafiti zivelisa ungcoliseko oluncinci ngexesha lokuveliswa nokusetyenziswa, kwaye kulula ukuzisebenzisa kwakhona. Olu hlobo lobuhlobo nokusingqongileyo alupheleli nje ekuhlangabezaneni neemfuno zophuhliso oluzinzileyo lweshishini lanamhlanje, kodwa lukwanciphisa umonakalo wezixhobo kunye nobude bexesha obubangelwa lungcoliseko lokusingqongileyo.
Isiphelo
Ukuqukumbela, ii-electrode zegrafiti zibonisa ukusebenza okugqwesileyo kwii-oven ze-arc zombane ngenxa yokuzinza kwazo kubushushu obuphezulu, ukuqhuba kombane okugqwesileyo, amandla alungileyo oomatshini, ukumelana nokutshayiswa kobushushu, ukumelana nokugqwala kweekhemikhali, i-coefficient ephantsi yokwandiswa kobushushu, ukuzithambisa, kunye nobuhlobo nokusingqongileyo. Ezi mpawu aziphuculi nje kuphela ukusebenza kakuhle kunye nesantya sokusetyenziswa kwamandla kwesi-oven se-arc zombane, kodwa zikwandisa kakhulu ubomi benkonzo yaso. Ke ngoko, ii-electrode zegrafiti ziye zaba zizinto ezibalulekileyo ezifunekayo kwii-oven ze-arc zombane, zibonelela ngenkxaso ebalulekileyo kuphuhliso lweshishini lanamhlanje le-metallurgical.
