Ukusetyenziswa kwe-electrode ye-graphite kwi-steelmaking yombane yesithando sombane inxulumene kakhulu nomgangatho we-electrode ngokwayo kunye nemeko yesithando somlilo (njengesithando somlilo esitsha okanye esidala, ukusilela komatshini, ukuveliswa okuqhubekayo, njl. njl.) kuhambelana ngokusondeleyo nokusebenza kwentsimbi (efana ne amabakala entsimbi, ixesha lokuvuthela ioksijini, intlawulo yesithando somlilo, njl.).Apha, kuphela ukusetyenziswa kwe-electrode yegraphite ngokwayo kuxoxwa ngayo, kwaye indlela yokusetyenziswa kwayo ilandelayo:
1.Ukuphela kokusetyenziswa kwe-graphite electrode
Iquka ukuthotywa kwezinto zegraphite ezibangelwa yi-arc kwiqondo lokushisa eliphezulu kunye nokulahlekelwa kwe-biochemical reaction phakathi kwe-graphite electrode end, intsimbi etyhidiweyo kunye ne-slag.Izinga lobushushu obuphezulu be-sublimation kwisiphelo se-electrode ikakhulu kuxhomekeke kuxinzelelo lwangoku oludlula kwi-electrode yegraphite, Okwesibini, inxulumene nobubanzi becala le-oxidized ye-electrode.Ngaphandle koko, ukusetyenziswa kokuphela kunxulumene nokuba i-electrode ifakwe kwintsimbi etyhidiweyo ukwandisa ikhabhoni.
2.I-oxidation yecala le-graphite electrode
Ukwakhiwa kweekhemikhali ze-electrode yi-carbon, i-Oxidation reaction iya kwenzeka xa i-carbon ixutywe nomoya, umphunga wamanzi kunye ne-carbon dioxide phantsi kweemeko ezithile.kunye nobungakanani be-oxidation kwicala le-electrode yegraphite inxulumene nenqanaba leyunithi ye-oxidation kunye nommandla wokuvezwa.Ngokubanzi, ukusetyenziswa kwe-electrode ye-graphite ecaleni kwenza malunga nama-50% osetyenziso lulonke lwe-electrode.
Kwiminyaka yakutshanje, ukuze kuphuculwe isantya sokunyibilikisa kwesithando sombane se-arc, ukuphindaphindeka komsebenzi wokuvuthela oksijini kuye kwanda, okukhokelela ekulahlekeni kwe-oxidation ye-electrode.Kwinkqubo yokwenza isinyithi, ubomvu be-trunk ye-electrode kunye ne-taper yesiphelo esisezantsi zivame ukubonwa, eyona ndlela enembile yokulinganisa ukuchasana kwe-oxidation ye-electrode.
3.Ilahleko yesiphunzi
Xa i-electrode isetyenziswa ngokuqhubekayo ekudibaneni phakathi kwe-electrode ephezulu nangaphantsi, icandelo elincinci le-electrode okanye ingono (intsalela) Ukwahlula kwenzeka ngenxa yokunciphisa i-oxidation yomzimba okanye ukungena kokuqhekeka.Ubungakanani bokulahleka kokuphela okushiyekileyo kuhambelana nokumila kwengono, uhlobo lwe-buckle, isakhiwo sangaphakathi se-electrode, i-vibration kunye nempembelelo yekholomu ye-electrode.
4.Ukuxobuka komphezulu kunye nokuwa kwebhloko
Kwinkqubo yokunyibilikisa, kubangelwa ukupholisa ngokukhawuleza kunye nokufudumeza, kunye nokuxhatshazwa kwe-thermal vibration resistance of the electrode ngokwayo.
5.Ukwaphulwa kwe-Electrode
Kubandakanya ukwaphuka komzimba we-electrode kunye nengono, ukuphuka kwe-Electrode kuhambelana nomgangatho wangaphakathi wegraphite electrode kunye nengono, Ulungelelwaniso loLungiso kunye nokusebenza kwentsimbi.Izizathu zihlala zigxininisa iingxabano phakathi kweentsimbi zetsimbi kunye nabavelisi be-electrode yegraphite.
