I-electrode yegraphite ibhekisa kwi-petroleum coke, inaliti ye-coke njengezinto ekrwada, itela yamalahle yokuncamathelisa, emva kokuba izinto ezikrwada zibaliwe, ukugaya okwaphukileyo, ukuxuba, ukuxova, ukubumba, ukubala, ukufakelwa, igraphite kunye nokulungiswa koomatshini kwaye yenziwe ngohlobo lokumelana nobushushu obuphezulu. imathiriyeli yegraphite conductive, ebizwa ngokuba yi-artificial graphite electrode (emva koku kuthiwa yigraphite electrode), ukwahlula kwigraphite yendalo njengolungiselelo lwezinto ezikrwada zegraphite electrode yendalo. Ngokwesalathiso somgangatho wayo, inokwahlulwa ibe yi-electrode yamandla egraphite, amandla aphezulu egraphite electrode kunye ne-ultra-high power graphite electrode.
I-electrode ye-graphite yamandla aphezulu yenziwe ngekhwalithi ephezulu yepetroleum coke (okanye i-coke yenaliti yenqanaba eliphantsi), ngamanye amaxesha umzimba we-electrode kufuneka ufakwe, iipropathi zawo zomzimba kunye noomatshini ziphezulu kunamandla aqhelekileyo e-electrode yegraphite, efana ne-resistivity ephantsi, evumela ukuba kukhululwe. ukuxinana kwangoku.
I-electrode ye-graphite yamandla aphezulu ivumela ukusetyenziswa koxinano lwangoku lwe-18 ~ 25A / cm2 i-electrode ye-graphite, esetyenziswa kakhulu kwi-high power arc furnace steel making.
Ukwenziwa kwentsimbi yesithando sombane ngoyena msebenzisi uphambili weeelectrode zegraphite. Imveliso yentsimbi ye-eAF eTshayina yenza malunga ne-18% yemveliso yentsimbi ekrwada, kunye ne-electrode yegraphite esetyenziswa ekwenzeni intsimbi ithatha i-70% ~ 80% yesixa-mali sisonke se-electrode yegraphite. I-steelmaking yesithando sombane kukusetyenziswa kwe-electrode yegraphite kwiziko langoku, ukusetyenziswa kombane ogqithisileyo kunye nentlawulo phakathi kwe-arc eveliswa ngumthombo wobushushu obuphezulu ukunyibilikisa.
-I-arc furnace isetyenziswa kakhulu kwimveliso ye-industrial yellow phosphorus kunye ne-silicon, njl. njl., uphawu lwayo luyinxalenye engezantsi ye-electrode conductive engcwatywe kwintlawulo yesithando somlilo, i-arc eyenziwe ngaphakathi kwendawo yezinto eziphathekayo, kwaye isebenzise i-furnace charge ngokwayo ekuchaseni. Ubushushu bamandla ukufudumeza intlawulo yeziko, enye yoxinaniso oluphezulu lwangoku olufunekayo -i-arc yomlilo idinga i-electrode yegraphite, njengesilicon 1 t ngemveliso yokusetyenziswa kwe-electrode yegraphite imalunga ne-100 kg, Malunga ne-40kg ye-electrode yegraphite iyadingeka ukuvelisa i-1t. phosphorus etyheli.
Iziko legraphitization lokuvelisa iimveliso zegraphite, iziko lokunyibilika lokunyibilikisa iglasi kunye neziko lombane lokuvelisa i-silicon carbide yeyeziko lokumelana. Izinto eziphathekayo kwisithando somlilo zimbini ukuchasana nokufudumala kunye nento yokufudumala. Ngokuqhelekileyo, i-electrode ye-graphite conductive ifakwe eludongeni lwesithando somlilo ekupheleni kwesithando somlilo, kwaye i-electrode yegraphite isetyenziselwa ukusetyenziswa kokuyeka apha.
I-electrode yegraphite engenanto ikwasetyenziselwa ukucubungula i-crucible eyahlukeneyo, isikhunta, isikhephe kunye nomzimba wokufudumeza kunye nezinye iimveliso ezikhethekileyo zegraphite. Ngokomzekelo, kwimboni yeglasi ye-quartz, i-10T ye-graphite electrode billet iyadingeka kwi-1T nganye yokuvelisa i-tube fuse yombane; I-100kg ye-graphite electrode billet iyafuneka ukuvelisa isitena se-quartz eyi-1t.
Ukususela ekuqaleni kwekota yesine ye-2016, kunye nokukhuthazwa kwemigaqo-nkqubo yokuhlaziywa kwe-supply-side-side reform kwi-iron kunye ne-industry yensimbi, ukuchithwa kwentsimbi yomgangatho ngokukhawuleza kube yinto ephambili ekupheliseni amandla okuvelisa umva. NgoJanuwari 10, 2017, i-Vice-Vice-Director ye-National Development and Reform Commission yathi kwi-2017 Council intlanganiso ye-CISA ukuba yonke imivalo yomgangatho kufuneka isuswe ngaphambi koJuni 30, 2017. Kwi-2017, umthamo we-eAF we-eAF steel wawumalunga ne-120 yezigidi zeetoni. , apho i-86.6 yezigidi zeetoni ibisenziwa kwaye i-15.6 yezigidi zeetoni ibingekho kwimveliso. Ukusukela ekupheleni kuka-Okthobha ka-2017, umthamo wemveliso we-eAF wawumalunga ne-26.5 yezigidi zeetoni, apho malunga ne-30% yaphinda yaqalwa. Ukuchaphazeleka kukuncitshiswa komthamo wesithando somlilo esiphakathi, intsimbi yombane yombane iqalwa ngokusebenzayo, kwaye inzuzo yezoqoqosho yentsimbi yombane ivelele. Isithando somlilo sombane sinesidingo esihle samandla aphezulu kunye ne-electrode ephezulu yegraphite yamandla, kunye nomdla wokuthenga okuphezulu.
Ngo-2017, ixabiso lasekhaya le-graphite electrode lenyuka, kwaye imfuno yaphesheya yenyuka. Iimarike zasekhaya neziphesheya zibuyele empumelelweni. E-China, ngenxa yokukhutshwa "kwentsimbi ephantsi", ukwanda kombane we-arc yesithando sombane, umda wemveliso yokukhusela indalo yamashishini ekhabhoni kunye nezinye izinto, ixabiso lasekhaya le-graphite electrode liye lanyuka ngo-2017, ebonisa ukuba imarike ye-graphite electrode yasekhaya iphakathi. unikezelo olufutshane. Ngaxeshanye, ukukhula kwe-electrode yaseTshayina kubonisa ukuba imfuno ye-electrode yegraphite yaphesheya yolwandle inamandla. Asekhaya kunye naphesheya kweelwandle abonise imfuno eqinileyo yee-electrode zegraphite, ishishini lisakwimeko yokubonelela.
Ke ngoko, umtsalane wotyalo-mali weshishini lamandla aphezulu egraphite electrode usenamandla.
Ngophuhliso lweshishini lentsimbi kunye nentsimbi yehlabathi, iziko lombane le-arc ngokuthe ngcembe ukuya kumandla amakhulu, amandla aphezulu kunye nolawulo oluzenzekelayo lwekhompyuter kunye neminye imiba yophuhliso, ukusetyenziswa kombane we-arc ombane ophezulu kuyanda, ukukhuthaza ukusetyenziswa kwamandla aphezulu egraphite electrode. .
Xa kuthelekiswa ne-United States, iYurophu, iJapan kunye namanye amazwe aphuhlileyo kunye nemimandla, ishishini laseTshayina lamandla aphezulu egraphite electrode laqala kade, ikakhulu lixhomekeke ekuthengisweni kwelizwe kwasekuqaleni, ukuveliswa kwamandla aphezulu egraphite electrode kude nemfuno. Iqhutywa luphuhliso loshishino lwentsimbi kunye nentsimbi kunye nenkqubela phambili yezobuchwepheshe, i-China iye ngokuthe ngcembe yaphula i-monopoly yetekhnoloji yamazwe angaphandle, kwaye amandla emveliso ye-electrode ephezulu yegraphite iye yanyuka, kwaye umgangatho wemveliso nawo uphuculwe ngokukhawuleza. Okwangoku, i-electrode ephezulu ye-graphite eveliswe e-China iye yafumana iziphumo ezilungileyo kwi-arc enkulu yombane yombane, kwaye zonke izalathisi zokusebenza zemveliso zinokufikelela kwinqanaba elihamba phambili lamazwe ngamazwe. Iimveliso ze-electrode ze-electrode zaseTshayina azinikezeli kuphela imarike yasekhaya, kodwa kunye nenani elikhulu lokuthumela kumazwe angaphandle kumazwe angaphandle, imfuno yeemveliso ezithunyelwa ngaphandle incinci.
Uphuhliso lwe-steelmaking yesithando somlilo ukuya kumandla aphezulu yindlela ebalulekileyo yokuphuhliswa kombane wokwenza intsimbi yombane. Kwixesha elizayo, imveliso yamandla aphezulu e-steelmaking yombane iya kunyuka, kwaye imfuno yayo yamandla aphezulu e-graphite electrode nayo iya kwanda, ukukhuthaza ukuveliswa kwamandla aphezulu e-graphite electrode e-China. Amashishini asekhaya anamandla aphezulu egraphite electrode anokwandisa ikhonkco lemizi-mveliso, enze uphando kunye nophuhliso lwemathiriyeli ekrwada, kwaye akhe izixhobo zokuvelisa, ezinokunciphisa ngempumelelo iindleko zeshishini kunye nokuphucula inzuzo yokusebenza kweshishini.
