Graphite electrode inoreva petroleum coke, tsono coke seyakabikwa, marasha tara yekunamira, mushure meyakasvibira yakabikwa, yakapwanyika kugaya, kusanganisa, kukanya, kuumba, calcination, impregnation, graphite uye mechanic process uye yakagadzirwa nemhando yekupisa kupisa kwe graphite conductive material, inonzi artificial graphite electrode (inozonzi graphite electrode), kuti isiyanise kubva kune yakasikwa graphite seyakagadzirwa kugadzirwa kwechisikigo graphite electrode. Zvinoenderana nemhando yayo indekisi, inogona kukamurwa kuita yakajairika simba graphite electrode, yakakwirira simba graphite electrode uye Ultra-yakakwirira simba graphite electrode.
High simba graphite electrode inogadzirwa nemhando yepamusoro petroleum coke (kana yakaderera giredhi tsono coke) kugadzirwa, dzimwe nguva muviri weelectrode unofanirwa kuisirwa, iwo emuviri uye emuchina zvimiro zvakakwirira kupfuura zvakajairika simba graphite electrode, senge yakaderera resistivity, ichibvumira yakakura. ikozvino density.
High power graphite electrode inobvumira kushandiswa kwezvino density ye18 ~ 25A/cm2 graphite electrode, inonyanya kushandiswa musimba guru arc furnace steel making.
Electric furnace steelmaking mushandisi mukuru wemagraphite electrodes. Kubuda kwesimbi yeEAF muChina kunokwana 18% yekubuda kwesimbi isina kuchena, uye graphite electrode inoshandiswa mukugadzira simbi inokwana 70% ~ 80% yehuwandu hwehuwandu hwegraphite electrode. Electric furnace steelmaking ndiko kushandiswa kwe graphite electrode muchoto chazvino, kushandiswa kwemagetsi akawandisa uye kubhadharisa pakati pearc inogadzirwa nepamusoro tembiricha yekupisa sosi kunyungudika.
-arc furnace inonyanya kushandiswa mukugadzirwa kweindasitiri yero phosphorus uye silicon, nezvimwewo, hunhu hwayo chikamu chezasi che conductive electrode yakavigwa muchoto chemoto, arc inoumbwa mukati meiyo dhizaini, uye shandisa choto chekuchaja pachako kubva mukupokana. yesimba rekupisa pakupisa choto chekuchaja, imwe yehurefu hwazvino hunodiwa -arc furnace inoda graphite electrode, senge silicon 1 t pakugadzirwa kusvika kudyiwa kwegraphite electrode ingangoita 100 kg, Inenge 40kg yegraphite electrode inodiwa kugadzira 1t. yero phosphorus.
Iyo graphitization yevira yekugadzira zvigadzirwa zvegraphite, choto chinonyunguduka chekunyungudusa girazi uye choto chemagetsi chekugadzirwa kwesilicon carbide ndechechoto chekudzivirira. Zvinhu zviri muchoto zvose zvinopikisa kupisa uye chinhu chinopisa. Kazhinji, iyo conductive graphite electrode yakaiswa mumadziro echoto pamagumo echoto chekudzivirira, uye graphite electrode inoshandiswa pakurega kushandiswa pano.
Iyo isina graphite electrode inoshandiswawo kugadzirisa akasiyana crucible, mold, chikepe uye kupisa muviri uye zvimwe zvakakosha-zvakaumbwa zvigadzirwa zvegraphite. Semuenzaniso, muindasitiri yegirazi yequartz, 10T yegraphite electrode billet inodiwa kune yega yega 1T yemagetsi fuse chubhu kugadzirwa; 100kg yegraphite electrode billet inodiwa kugadzira 1t quartz zvidhinha.
Kubva pakutanga kwekota yechina ye2016, nekusimudzirwa kwekugadzirisa-side reform policy muindasitiri yesimbi nesimbi, kuputsa pasi pasi pesimbi kwakangoerekana kwave kunonyanya kukosha mukubvisa shure kwekugadzira simba. Musi wa10 Ndira, 2017, mutevedzeri weMutungamiriri weNational Development and Reform Commission akataura pamusangano weCISA we2017 Council kuti mabhawa ese epasi anofanira kubviswa pamberi paChikumi 30, 2017. Muna 2017, huwandu hweChina hweEAF simbi hwaive hunosvika matani emamiriyoni zana nemakumi maviri. , ayo matani mamiriyoni 86.6 akanga ari mukugadzirwa uye mamiriyoni 15.6 matani akanga asiri kugadzirwa. Kubva pakupera kwaGumiguru 2017, huwandu hwekugadzira eAF hwaive hunosvika 26.5 miriyoni matani, ayo angangoita makumi matatu muzana akatangazve. Kukanganiswa nekuderedzwa kwehutoni hwepakati frequency furnace, simbi yemagetsi yevira inotangwa zvine mutsindo, uye hupfumi hwehupfumi hwesimbi yehuni hwakatanhamara. Yemagetsi choto chesimbi ine kudiwa kwakanaka kwesimba repamusoro uye Ultra-yakakwirira simba graphite electrode, uye kukwira kwekutenga chido.
Muna 2017, mutengo wepamba wegraphite electrode wakakwira, uye kudiwa kwemhiri kwemakungwa kwakakwira. Misika yese yemumba neyemhiri kwemakungwa yakadzokera mukubudirira. MuChina, nekuda kwekucheneswa kwe "simbi yepasi", kuwedzera kwemagetsi arc furnace kugona, kuchengetedzwa kwezvakatipoteredza muganho wekugadzirwa kwemabhizinesi kabhoni uye zvimwe zvinhu, mutengo wepamba graphite electrode wakakwira muna 2017, zvichiratidza kuti musika wepasi pegirafu electrode uri mukati. kuperevedza. Panguva imwecheteyo, kukura kwe graphite electrode kunoratidza kuti mhiri kwemakungwa graphite electrode kudiwa kwakasimba. Zvemukati nekumhiri kwemakungwa zvakaratidza kudiwa kwakasimba kwemagraphite electrode, iyo indasitiri ichiri mushopu yekugovera mamiriro.
Naizvozvo, kukwezva kwekudyara kweiyo yakakwirira simba graphite electrode indasitiri ichiri yakasimba.
Nekuvandudzwa kweindasitiri yesimbi nesimbi yepasi rose, yemagetsi arc furnace zvishoma nezvishoma kusvika kuhombe, Ultra-yakakwirira simba uye komputa otomatiki kutonga uye zvimwe zvinhu zvekusimudzira, kushandiswa kwesimba remagetsi arc furnace kuri kuwedzera, kukurudzira kushandiswa kwesimba repamusoro graphite electrode. .
Zvichienzaniswa neUnited States, Europe, Japan nedzimwe nyika dzakasimukira nematunhu, China high power graphite electrode industry yakatanga kunonoka, kunyanya ichivimba nekutenga kunze kwenyika pakutanga, kugadzirwa kwemagetsi emagetsi emagetsi epamusoro kuri kure nezvinodiwa. Inotungamirwa nekuvandudzwa kweindasitiri yesimbi nesimbi uye kufambira mberi kwetekinoroji, China yave kutyora zvishoma nezvishoma tekinoroji yenyika dzekunze, uye kugona kwekugadzira kwesimba repamusoro graphite electrode kwave kukwira, uye mhando yechigadzirwa yakagadziridzwa nekukurumidza. Parizvino, iyo yakakwira simba graphite electrode inogadzirwa muChina yakawana mhedzisiro yakanaka muhombe yemagetsi arc furnace, uye ese maratidziro ekuita echigadzirwa anogona kusvika kune inotungamira nhanho yenyika. China yakakwira simba graphite electrode zvigadzirwa hazvisi kungopa musika wemumba, asiwo nhamba huru yekutengesa kune dzimwe nyika, kudiwa kwezvigadzirwa zvinotengeswa kunze kwenyika kushoma.
Iko kuvandudzwa kwechoto chekugadzira simbi kune yakakwirira simba itsika yakakosha yekuvandudzwa kwemagetsi emagetsi ekugadzira simbi. Mune ramangwana, kubuda kwesimbi yemagetsi emagetsi emoto kuchawedzera, uye kudiwa kwayo kwemagetsi emagetsi emagetsi emagetsi kuchawedzerawo, kusimudzira kugadzirwa kwemagetsi emagetsi emagetsi epamusoro muChina. Emba yakakwira simba graphite electrode mabhizinesi anogona kuwedzera iyo maindasitiri ketani, kuita tsvakiridzo nekuvandudza zvigadzirwa, uye kuvaka michina yekugadzira, inogona kunyatso kudzikisa mutengo webhizinesi uye kugadzirisa purofiti yekushanda kwebhizinesi.
