Carbon material production process is akanyatsodzorwa system engineering, kugadzirwa kwegraphite electrode, special carbon materials, aluminium kabhoni, itsva-yepamusoro-yekupedzisira kabhoni zvinhu hazviparadzaniswe nekushandiswa 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, kushomeka 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, vagadziri vemagetsi emagetsi, masangano ekutsvagisa sainzi kukurukura.
Kunyangwe kugadzirwa kwemaindasitiri kwetsono coke muChina kwave gare gare kupfuura kwemabhizinesi ekunze, kwakakura nekukurumidza mumakore achangopfuura uye kwatanga kuumbwa.Panyaya yehuwandu hwekugadzira vhoriyamu, inogona 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 hombe UHP uye HP graphite electrode, kunyanya hapana yepamusoro-yemhando yejoint coke coke inogona kusangana nekugadzirwa kwegraphite electrode joint.
Mabhizinesi ekunze kabhoni anogadzira mahombe akatemerwa UHP, HP graphite electrode inowanzova sarudzo yekutanga yemhando yepamusoro petroleum tsono coke seyakanyanya mbishi coke, maJapan mabhizinesi ecarbon 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, iyo tsono coke inogadzirwa nemabhizinesi akasiyana-siyana inowanzofananidzwa nekutengeserana kwekuita indexes yekunze tsono coke neyakajairwa kuita indexes, senge madota emukati, density yechokwadi, sarufa 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 ekabhoni anofanirwawo kutarisisa kuratidzwa kwetsono 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.Nokuti izvi zvinopisa zvinhu zvetsono coke zvakakosha zvikuru pakutonga kwegraphitization maitiro mukugadzirwa kwegraphite electrode, hongu, simba rekushisa kweasphalt coke rakagadzirwa 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, reshiyo: 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 makemikari emarasha 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 yemazuva ese kemikari LPC-U giredhi remarasha chiyero chetsono coke.Kukosha kweanisotropy kwakadzikira zvakanyanya pane kutsva Daily chemical LPC-U marasha anoyera tsono coke.
Ultra yakakwira simba graphite electrode kugadzira anisotropic degree performance analysis ndiyo fungidziro yetsono coke raw material quality kana isiri yakakosha nzira yekuongorora, saizi yedhigirii reanisotropy, hongu, zvakare ine imwe pesvedzero pakugadzirwa kwe electrode, chiyero che anisotropy yemagetsi yakanyanyisa kupisa kuvhunduka kuita kupfuura iyo anisotropy degree yeavhareji simba remagetsi diki yakanaka.
Parizvino, kugadzirwa kwemarasha tsono coke muChina kwakakura kupfuura iyo petroleum tsono coke.Nekuda kwemutengo wakakwira wezvigadzirwa uye mutengo wemabhizinesi ecarbon, zvakaoma kushandisa zana muzana remumba tsono coke mukugadzirwa kweUHP electrode, uku uchiwedzera chimwe chikamu cheyakanzi 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 kuputika 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 kwegraphite kemikari kutevedzana.Izvi zvinonyanya kuoneka mune dzakatevedzana graphitization process.
Tafura 3 inoratidza mutsara uye vhoriyamu shanduko uye tembiricha magiredhi matatu epetroleum tsono coke inogadzirwa naConocophilips kuUK.Kuwedzera kwemutsara kunoitika kekutanga apo mafuta tsono coke inotanga kupisa, asi tembiricha pakutanga kwemutsara mutsetse kazhinji inononoka kuseri kwetembiricha yecalcination.Kubva 1525 ℃ kusvika 1725 ℃, mutsara wekuwedzera kunotanga, uye tembiricha yemhando yese yemutsara chibvumirano idiki, 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 yeongororo yeOsaka Industrial Technology Test Institute muJapan inoratidza kuti kunyanyisa kupisa kwecoke, ndiko kukura kwetembiricha ye shrinkage, kusvika 500 ~ 600 ℃ mutsara wekudzikira tembiricha, uye kutanga kwetambo shrinkage tembiricha yakadzikira. , pa1150 ~ 1200 ℃ yakatanga kuitika mutsetse shrinkage, inovawo hunhu hweakajairwa kunonoka petroleum coke.
Izvo zvirinani zvimiro zvekupisa uye kukura kwe anisotropy yetsono coke, inodzikisira tembiricha 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 chiitiko maitiro.
3 mhedziso
Tenzi hunhu hwakasiyana hwezvigadzirwa, sarudza inonzwisisika michina inoenderana, yakanaka musanganiswa wetekinoroji, uye manejimendi ebhizinesi ane sainzi uye ane musoro, iyi nhevedzano yehurongwa hwese hwese inodzorwa zvakasimba uye yakagadzikana, inogona kunzi ine hwaro hwekugadzira yakakwirira- mhando yepamusoro-yepamusoro simba, yakakwirira simba graphite electrode.
