Graphite electrode inoreva petroleum coke, needle coke sezvinhu zvisina kugadzirwa, marasha emarasha ekunamira, mushure mekunamwa zvinhu zvisina kugadzirwa, kupwanywa kwekukuya, kusanganisa, kukanya, kuumba, calcination, impregnation, graphite uye mechanical processing uye yakagadzirwa nemhando yekupisa kwakanyanya kwe graphite conductive material, inonzi artificial graphite electrode (inozonzi graphite electrode), kuti isiyaniswe ne natural graphite sekugadzirwa kwezvinhu zvisina kugadzirwa zve natural graphite electrode. Zvichienderana ne quality index yayo, inogona kukamurwa kuita ordinary power graphite electrode, high power graphite electrode uye ultra-high power graphite electrode.
Electrode yegrafiti ine simba guru inogadzirwa nekugadzirwa kwepetroleum coke (kana kuti neelement coke yemhando yepamusoro), dzimwe nguva muviri we electrode unofanirwa kunyudzwa, hunhu hwayo hwepanyama uye hwemakanika hwakakwira kupfuura electrode yegrafiti ine simba rakajairika, senge resistivity yakaderera, zvichibvumira huwandu hwakawanda hwemagetsi.
Electrode yegrafiti ine simba guru inobvumira kushandiswa kwehuwandu hwemagetsi e18 ~ 25A/cm2 graphite electrode, inonyanya kushandiswa mukugadzira simbi yefurnace ine simba guru.
Kugadzira simbi muchoto chemagetsi kunonyanya kushandisa ma electrode egrafiti. Kubuda kwesimbi ye eAF muChina kunotora 18% yezvinobuda musimbi isina kucheneswa, uye electrode yegrafiti inoshandiswa mukugadzira simbi inotora 70% ~ 80% yehuwandu hwese hwe graphite electrode. Kugadzira simbi muchoto chemagetsi kunoreva kushandiswa kwe graphite electrode muchoto chemagetsi, kushandiswa kwemagetsi akawandisa uye kuchaja pakati pe arc inogadzirwa nekupisa kwakanyanya kunobuda pakupisa.
-arc furnace inonyanya kushandiswa mukugadzira phosphorus yeyero yeindasitiri nesilicon, nezvimwewo, hunhu hwayo chikamu chezasi che electrode inofambisa mvura yakavigwa muchoto, arc yakaumbwa mukati mechikamu chezvinhu, uye inoshandisa choto pachayo kubva pakurwisa kwesimba rekupisa kusvika pachoto chekupisa, chimwe chezvinhu zvinodiwa nehukuru hwemazuva ano -arc furnace inoda graphite electrode, senge silicon 1 t pakugadzirwa kusvika pakushandiswa kwe graphite electrode inenge 100 kg, Inenge 40kg ye graphite electrode inodiwa kuti igadzire 1t yero phosphorus.
Chitofu chegrafitisation chekugadzira zvigadzirwa zvegrafiti, chitofu chekunyungudutsa chegirazi rekunyungudutsa uye chitofu chemagetsi chekugadzira silicon carbide ndezvechitofu cheresistance. Zvinhu zviri muchoto ndezveresistance yekudziyisa uye chinhu chekudziyisa. Kazhinji, electrode yegrafiti inofambisa inoiswa mumadziro echoto pamucheto wechoto cheresistance, uye electrode yegrafiti inoshandiswa kushandiswa zvachose pano.
Electrode yegrafiti isina chinhu inoshandiswawo pakugadzira zvigadzirwa zvakasiyana-siyana zvegrafiti zvinobvira pamoto, chakuvhuvhu, chikepe nemuviri wekupisa nezvimwe zvigadzirwa zvegrafiti zvine chimiro chakakosha. Semuenzaniso, muindasitiri yegirazi requartz, 10T ye graphite electrode billet inodiwa pa1T yega yega yekugadzira machubhu emagetsi efuse; 100kg ye graphite electrode billet inodiwa kugadzira 1t quartz brick.
Kubva pakutanga kwekota yechina ya2016, nekusimudzira mitemo yekuchinja-chinja kwezvikamu muindasitiri yesimbi nesimbi, kupwanya simbi yepasi kwave chinhu chinonyanya kukosha mukubvisa kugona kwekugadzira zvinhu kumashure. Musi wa10 Ndira 2017, mutevedzeri weMutungamiriri weNational Development and Reform Commission akataura pamusangano weCISA we2017 Council kuti matanda ese pasi anofanira kubviswa pamberi pa30 Chikumi 2017. Muna 2017, kugona kwese kwesimbi ye eAF muChina kwaive matani angangoita 120 miriyoni, ayo matani 86.6 miriyoni aive ari kugadzirwa uye matani 15.6 miriyoni aive asisagadzirwe. Pakupera kwaGumiguru 2017, kugona kwekugadzira kwe eAF kwaive matani angangoita 26.5 miriyoni, ayo angangoita 30% akatangwazve. Yakanganiswa nekuderedzwa kwesimba refurnace yepakati, simbi yefurnace yemagetsi yakatanga kushanda nesimba, uye kubatsirwa kwehupfumi kwesimbi yefurnace yemagetsi kwakakosha. Simbi yefurnace yemagetsi ine kudiwa kwakanaka kwesimba rakawanda uye graphite electrode yesimba rakawanda, uye kufarira kukuru kwekutenga.
Muna 2017, mutengo we graphite electrode yemuno wakakwira, uye kudiwa kwekunze kwenyika kwakakwira. Misika yemuno neyekunze kwenyika yakadzokera kubudiriro. MuChina, nekuda kwekubviswa kwe "floor steel", kuwedzera kwesimba remagetsi e arc furnace, muganho wekuchengetedza zvakatipoteredza wemakambani ecarbon nezvimwe zvinhu, mutengo we graphite electrode yemuno wakakwira zvakanyanya muna 2017, zvichiratidza kuti musika we graphite electrode yemuno hauna kuwanikwa. Panguva imwe chete, kukura kwe graphite electrode yemuChina kunoratidza kuti kudiwa kwe graphite electrode yemuno kwakasimba. Munyika nekunze kwenyika zvakaratidza kudiwa kwakasimba kwe graphite electrodes, indasitiri ichiri mukushomeka.
Saka, kukwezva kwemari kweindasitiri ye graphite electrode ine simba guru kuchiri kwakasimba.
Nekukura kweindasitiri yepasi rose yesimbi nesimbi, tanuru yemagetsi yearc zvishoma nezvishoma kusvika pakukura kukuru, simba repamusoro-soro uye kombiyuta otomatiki kudzora uye zvimwe zvinhu zvekuvandudza, kushandiswa kwetanuru yemagetsi yearc ine simba guru kuri kuwedzera, zvichikurudzira kushandiswa kwe graphite electrode ine simba guru.
Zvichienzaniswa neUnited States, Europe, Japan nedzimwe nyika dzakabudirira nenzvimbo dzakabudirira, indasitiri yemagetsi egraphite eChina ine simba guru yakatanga kunonoka, ichinyanya kuvimba nekutenga zvinhu zvinotengeswa kunze kwenyika nekukurumidza, kugadzirwa kwemagetsi egraphite ane simba guru hakusi kudiwa zvakanyanya. Nekuda kwekuvandudzwa kweindasitiri yesimbi nesimbi uye kufambira mberi kwetekinoroji, China yakaputsa zvishoma nezvishoma tekinoroji yenyika dzekunze, uye kugona kwekugadzira magetsi egraphite ane simba guru kwave kuchiwedzera, uye mhando yechigadzirwa yave kuvandudzwa nekukurumidza. Parizvino, magetsi egraphite ane simba guru akagadzirwa muChina akawana mhedzisiro yakanaka muchoto chikuru chemagetsi, uye zvese zvinoonekwa pakushanda kwechigadzirwa zvinogona kusvika padanho rekutungamira repasi rose. Zvigadzirwa zvemagetsi egraphite eChina zvine simba guru hazvingopi chete musika wemuno, asiwo huwandu hwakawanda hwezvinhu zvinotengeswa kunze kwenyika, kudiwa kwezvinhu zvinotengeswa kunze kwenyika kwakaderera.
Kuvandudzwa kwekugadzira simbi dzechoto kusvika pamagetsi akawanda inzira inokosha yekuvandudzwa kweindasitiri yekugadzira simbi dzechoto chemagetsi. Mune ramangwana, kubuda kwesimbi dzechoto chemagetsi dzine simba guru kuchawedzera, uye kudiwa kwadzo kwe graphite electrode ine simba guru kuchawedzerawo, zvichikurudzira kugadzirwa kwe graphite electrode ine simba guru muChina. Makambani emuno ane simba guru re graphite electrode anogona kuwedzera cheni yemaindasitiri, kuita tsvakiridzo nekugadzira zvinhu zvakagadziriswa, uye kuvaka michina yekugadzira, izvo zvinogona kuderedza zvinobudirira mari yebhizinesi uye kuvandudza purofiti yekushanda kwebhizinesi.
