Carbon material production process is akanyatsodzorwa system engineering, kugadzirwa kwegraphite electrode, special carbon materials, aluminium kabhoni, itsva-yepamusoro-yekupedzisira kabhoni zvinhu hazviparadzaniswe kubva mukushandiswa kwezvinhu, midziyo, tekinoroji, manejimendi mana ekugadzira zvinhu uye zvine hukama hukama. teknolojia.
Raw zvinhu ndizvo zvakakosha zvinotaridza hunhu hwekabhoni zvinhu, uye kuita kwezvakagadzirwa zvinhu zvinotaridza mashandiro ezvakagadzirwa kabhoni. Pakugadzirwa kweUHP uye HP graphite electrodes, high quality tsono coke ndiyo yekutanga sarudzo, asiwo yakakwirira mhando binder asphalt, impregnating agent asphalt. Asi chete zvemhando yepamusoro zvigadzirwa, kushaikwa kwemidziyo, tekinoroji, manejimendi zvinhu uye zvine chekuita nehunyanzvi tekinoroji, haikwanise kuburitsa yemhando yepamusoro UHP, HP graphite electrode.
Ichi chinyorwa chinotarisa pane hunhu hwemhando yepamusoro tsono coke kutsanangura mamwe maonero emunhu, kune vanogadzira tsono coke, vanogadzira maelectrode, masangano ekutsvagisa esainzi kuti vakurukure.
Kunyangwe kugadzirwa kwemaindasitiri kwetsono coke muChina kwave gare gare kupfuura kwemabhizinesi ekunze, kwakakura nekukurumidza mumakore achangopfuura uye kwatanga kuumbwa. Panyaya yehuwandu hwekugadzira vhoriyamu, inogona kunyatso kuzadzisa kudiwa kwetsono coke yeUHP uye HP graphite electrodes inogadzirwa nemabhizinesi epamba kabhoni. Nekudaro, kuchine imwe gap mumhando yetsono coke kana ichienzaniswa nemabhizinesi ekunze. Kuchinja kwekuita kwebatch kunokanganisa kudiwa kwemhando yepamusoro tsono coke mukugadzirwa kwehukuru hukuru UHP uye HP graphite electrode, kunyanya hapana yemhando yepamusoro yejoint coke coke inogona kusangana nekugadzirwa kwegraphite electrode joint.
Mabhizinesi ekunze kabhoni anogadzira mahombe akaremerwa UHP, HP graphite electrode inowanzova sarudzo yekutanga yemhando yepamusoro petroleum tsono coke seyakanyanya mbishi coke, mabhizinesi eJapan kabhoni anoshandisawo mamwe marasha akatevedzana tsono coke seyakabikwa, asi chete kune inotevera φ. 600 mm tsanangudzo ye graphite electrode kugadzirwa. Parizvino, tsono coke muChina inonyanya kuve marasha akatevedzana tsono coke. Kugadzirwa kwemhando yepamusoro-soro yakakura UHP graphite electrode nemabhizinesi ecarbon kazhinji inotsamira kune inotengeswa peturu yakatevedzana tsono coke, kunyanya kugadzirwa kwemhando yepamusoro yakabatana neyekune dzimwe nyika yeJapan Suishima oiri yakatevedzana tsono coke uye yeBritish HSP mafuta akatevedzana tsono coke seyakabikwa coke.
Parizvino, tsono coke inogadzirwa nemabhizinesi akasiyana-siyana inowanzofananidzwa nekutengeserana kwekuita indexes yekunze tsono coke neyakajairwa kuita indexes, senge madota emukati, density yechokwadi, sulfur yemukati, nitrogen yemukati, particle size distribution, thermal expansion coefficient and so. on. Nekudaro, kuchine kushomeka kwemagiredhi akasiyana etsono coke classification kana ichienzaniswa nenyika dzekunze. Naizvozvo, kugadzirwa kwetsono coke colloquially zvakare ye "zvinhu zvakabatana", haigone kuratidza giredhi remhando yepamusoro premium tsono coke.
Pamusoro pekufananidza kuita kwakajairwa, mabhizinesi ekhabhoni anofanirwawo kutarisisa kune hunhu hwetsono coke, senge kurongeka kweiyo thermal yekuwedzera coefficient (CTE), simba rechikamu, anisotropy degree, data yekuwedzera mune isina- inhibited state uye inhibited state, uye tembiricha inosiyana pakati pekuwedzera nekukanda. Nekuti izvi zvinopisa zvimisikidzo zvetsono coke zvakakosha zvikuru pakudzora kwegraphitization process mukugadzira graphite electrode, hongu, pesvedzero yemafuta ekupisa easphalt coke akaumbwa mushure mekugochwa kwebinder uye impregnating agent asphalt haina kubviswa.
1. Kufananidza anisotropy yetsono coke
(A) Muenzaniso: φ 500 mm UHP electrode body yeA domestic carbon factory;
Raw material tsono coke: Japanese itsva Chemical LPC-U giredhi, reshiyo: 100% LPC-U giredhi; Kuongorora: SGL Griesheim chirimwa; Zviratidzo zvekushanda zvinoratidzwa muTable 1.
(B) Muenzaniso: φ 450 mmHP electrode muviri weimba carbon factory; Raw material tsono coke: yepamba fekitori mafuta tsono coke, chiyero: 100%; Kuongorora: Shandong Bazan Carbon Plant; Zviratidzo zvekushanda zvinoratidzwa muTable 2.
Sezvinoonekwa kubva pakuenzanisa Tafura 1 uye Tafura 2, iyo lPC-U giredhi yetsono coke yemazuva ese emakemikari marasha matanho ane hombe anisotropy yezvinhu zvinopisa, umo iyo anisotropy yeCTE inogona kusvika 3.61 ~ 4.55, uye iyo anisotropy of resistivity yakakurawo, inosvika 2.06 ~ 2.25. Kunze kwekusimba kwekushanduka kwemba yepetroleum tsono coke iri nani pane iyo yekemikari mitsva yemazuva ese LPC-U giredhi remarasha chiyero chetsono coke. Iko kukosha kweanisotropy yakaderera zvakanyanya pane iyo yeDaily kemikari LPC-U marasha ekuyera tsono coke.
Ultra yakakwira simba graphite electrode kugadzira anisotropic degree performance analysis ndiyo fungidziro yetsono coke raw material quality kana kwete yakakosha nzira yekuongorora, saizi yedhigirii reanisotropy, hongu, zvakare ine imwe pesvedzero pakugadzirwa kwe electrode, chiyero che anisotropy yemagetsi yakanyanya kupisa kuvhunduka kuita kupfuura iyo anisotropy dhigirii yeavhareji simba reiyo electrode diki yakanaka.
Parizvino, kugadzirwa kwemarasha tsono coke muChina yakakura kwazvo kupfuura iyo petroleum tsono coke. Nekuda kwemutengo wakakwira wezvigadzirwa uye mutengo wemabhizinesi ecarbon, zvinonetsa kushandisa zana muzana remumba tsono coke mukugadzira UHP electrode, uku uchiwedzera chimwe chikamu cheyakaverengerwa petroleum coke uye graphite poda kugadzira electrode. Naizvozvo, zvakaoma kuongorora anisotropy yemumba tsono coke.
2. Linear uye volumetric zvimiro zvetsono coke
Iyo mutsara uye volumetric shanduko yekushanda yetsono coke inonyanya kuratidzwa mune graphite process inogadzirwa ne electrode. Nekushanduka kwekushisa, tsono coke ichaita mutsara uye volumetric kuwedzera uye chibvumirano panguva yekushanda kwegraphite process heat up, iyo inobata zvakananga kuchinja kwemutsara uye volumetric ye electrode yakakangwa billet mu graphite process. Izvi hazvina kufanana nekushandiswa kwezvinhu zvakasiyana-siyana zvecoke mbishi, magiredhi akasiyana etsono coke shanduko. Uyezve, tembiricha yemhando yemutsara uye vhoriyamu shanduko yemagiredhi akasiyana etsono coke uye calcined petroleum coke zvakare akasiyana. Chete nekugona hunhu uhu hwecoke mbishi tinogona kudzora zvirinani nekugadzirisa kugadzirwa kwe graphite kemikari kutevedzana. Izvi zvinonyanya kuoneka mune dzakatevedzana graphitization process.
Tafura 3 inoratidza mutsara uye vhoriyamu shanduko uye tembiricha yemhando dzemagiredhi matatu epetroleum tsono coke inogadzirwa naConocophilips kuUK. Linear kuwedzera kunoitika kana oiri tsono coke inotanga kupisa, asi tembiricha pakutanga kwemutsara mutsetse kazhinji inosarira kuseri kwetembiricha yecalcination. Kubva 1525 ℃ kusvika 1725 ℃, mutsara wekuwedzera kunotanga, uye tembiricha yemhando yese yemutsara chibvumirano yakatetepa, chete 200 ℃. Tembiricha yemhando yese yekumisikidza kweyakajairika kunonoka petroleum coke yakakura kupfuura iyo yetsono coke, uye marasha tsono coke iri pakati pezviviri, zvakati kurei kupfuura mafuta tsono coke. Mhedzisiro yemhedzisiro yeOsaka Industrial Technology Test Institute muJapan inoratidza kuti kunyanyisa kupisa kwe coke, iyo yakakura mitsara yekudzikira tembiricha, kusvika 500 ~ 600 ℃ mutsara shrinkage tembiricha, uye kutanga kwemutsara shrinkage tembiricha yakadzikira. , pa1150 ~ 1200 ℃ yakatanga kuitika mutsetse shrinkage, ariwo hunhu hweakajairwa kunonoka petroleum coke.
Izvo zvirinani kupisa kwemafuta uye kukura kwe anisotropy yetsono coke, ndiko kupfupika kwetembiricha yemutsara mutsetse. Mamwe emhando yepamusoro mafuta tsono coke chete 100 ~ 150 ℃ linear contraction tembiricha renji. Izvo zvinobatsira kwazvo kumabhizinesi ekabhoni kutungamira graphitization process kugadzirwa mushure mekunzwisisa hunhu hwekuwedzera mutsara, kudonhedza uye kuwedzerazve kweakasiyana mbizha zvinhu coke, izvo zvinogona kudzivirira zvimwe zvisingakoshi zvemhando yemarara zvigadzirwa zvinokonzerwa nekushandisa yechinyakare ruzivo maitiro.
3 mhedziso
Tenzi hunhu hwakasiyana hwezvigadzirwa, sarudza inonzwisisika michina inoenderana, yakanaka musanganiswa wetekinoroji, uye manejimendi ebhizinesi akawedzera zvesainzi uye zvine musoro, iyi nhevedzano yehurongwa hwese hwese inodzorwa zvakasimba uye yakagadzikana, inogona kunzi ine hwaro hwekugadzira yakakwirira- mhando yepamusoro-yepamusoro simba, yakakwirira simba graphite electrode.
