Chinhu chikuru chinoshandiswa mukugadzira graphite electrode i calcined petroleum coke. Saka rudzii rwe calcined petroleum coke rwakakodzera kugadzirwa kwe graphite electrode?
1. Kugadzirwa kwemafuta asina kubikwa mumafuta ekubikisa kunofanirwa kuzadzisa musimboti wekugadzira petroleum coke yemhando yepamusoro, uye kunyorwa kwepetroleum coke yemhando yepamusoro kunofanira kunge kwakanyatsogadzirwa nefiber. Maitiro ekugadzira anoratidza kuti kuwedzera 20-30% thermal cracking residue coke mumafuta asina kubikwa mumafuta ane mhando yepamusoro, izvo zvinogona kusangana nezvinodiwa zvekugadzira graphite electrode.
2. Simba rakakwana rekuvaka.
Dhayamita yezvinhu zvakabikwa inotanga kupwanywa, kunyungudika, uye kupwanywa nguva yekuderedza kupwanywa, inosangana nezvinodiwa zvekubatanidza saizi yegirasi resikweya.
3. Kuchinja kwehuwandu hwecoke kunofanira kunge kudiki mushure mekupwanyika, izvo zvinogona kuderedza kushushikana kwemukati muchigadzirwa kunokonzerwa nekuzvimba kwemuchina wakadzvanywa uye kuderera kwekushanda kwekugadzira nekugadzira graphitization.
4. Coke inofanira kunge iri nyore kugadzira graphitization, zvigadzirwa zvinofanirwa kunge zvisina simba rekudzivirira, kupisa kwakanyanya uye kuwedzera kwekupisa kwakaderera.
5. Kusagadzikana kweCoke kunofanira kunge kuri pasi pe1%,Chinhu chinoshanduka chinoratidza kudzika kwekubikira uye chinokanganisa zvinhu zvakasiyana-siyana.
6. Coke inofanira kugochwa pa1300℃ kwemaawa mashanu, uye simba rayo rechokwadi harifanirwe kunge riri pasi pe2.17g/cm2.
7. Huremu hwesarufa mucoke hahufanirwe kupfuura 0.5%.
North America neSouth America ndidzo dzinogadzira petroleum coke zvakanyanya pasi rose, nepo Europe ichizvigadzirira yega petroleum coke. Vagadziri vakuru vepetroleum coke muAsia ndiKuwait, Indonesia, Taiwan neJapan nedzimwe nyika nenzvimbo.
Kubva kuma1990, nekukura kwehupfumi hweChina nekukurumidza, kudiwa kwemafuta kwave kuchiwedzera gore negore.
Kana huwandu hwemafuta asina kucheneswa hukawedzera zvakanyanya, huwandu hwakawanda hwepetroleum coke, chinhu chinobva mukucheneswa kwemafuta asina kucheneswa, huchagadzirwa zvisingadzivisike.
Zvichienderana nekupararira kwemafuta epetroleum coke muChina, dunhu rekumabvazuva kweChina riri pamusoro, richipa anopfuura 50% yemafuta ese epetroleum coke muChina.
Inoteverwa nedunhu rekuchamhembe kwakadziva kumabvazuva nedunhu rekuchamhembe kwakadziva kumadokero.
Huremu hwesarufa mupetroleum coke hune basa guru mukushandiswa kwayo nemutengo wayo, uye kugadzirwa kwepetroleum coke ine graphitized kunogumira pamitemo yakasimba yezvakatipoteredza kunze kwenyika, iyo inorambidza kupiswa kwepetroleum coke ine huremu hwakawanda muzvicherwa zvakawanda uye mafekitori emagetsi munyika.
Coke yepetroleum yemhando yepamusoro uye ine sulfur shoma inoshandiswa zvakanyanya mumaindasitiri esimbi, aruminiyamu nekabhoni. Kuwedzera kwekudiwa kwayo kunowedzera kukosha kwecoke yepetroleum kanoverengeka.
Mumakore achangopfuura, kushandiswa kwepetroleum coke muChina kuri kuramba kuchikura nekukurumidza, uye kudiwa kwepetroleum coke mumisika yese yevatengi kuri kuramba kuchikura.
Aruminiyamu ndiyo inodarika hafu yekushandiswa kwepetroleum coke muChina. Inonyanya kushandiswa muanode yakabikwa kare, uye kudiwa kwesulfur coke yepakati nepasi kwakanyanya.
Zvigadzirwa zvekabhoni zvinosvika chikamu chimwe muzvishanu chezvinodiwa zvepetroleum coke, iyo inonyanya kushandiswa kugadzira maelectrode egraphite. Maelectrode egraphite epamusoro ane kukosha kukuru uye anobatsira zvikuru.
Kushandiswa kwemafuta kunodarika chikamu chimwe mugumi, uye mafekitori emagetsi, porcelain nemagirazi anoshandisa akawanda.
Chiyero chekushandiswa kwesimbi muindasitiri yekunyungudutsa simbi chinosvika chimwe chete kusvika makumi maviri, kushandiswa kwesimbi yekugadzira simbi.
Pamusoro pezvo, kudiwa kweindasitiri yesilicon isimba rinofanirawo kutariswa.
Chikamu chekutengesa kunze kwenyika ndicho chidiki kwazvo, asi kudiwa kwecoke yepetroleum yepamusoro mumusika wekunze kwenyika kuchiri kukosha. Kunewo chikamu chakati checoke ine sulfur yakawanda, pamwe nekushandiswa kweinodyiwa mudzimba.
Nekukura kwehupfumi hweChina, zvigayo zvesimbi zvemuno zveChina, zvigayo zvealuminium nezvimwe zvakanakira hupfumi zvakavandudzika zvishoma nezvishoma, kuitira kuwedzera kugadzirwa uye mhando yezvigadzirwa, makambani mazhinji makuru akatenga zvishoma nezvishoma graphenized petroleum coking carbonizer. Kudiwa kwemuno kuri kuwedzera. Panguva imwe chete, nekuda kwemutengo wakakwira wekushanda, mari yakawanda yekudyara uye zvinodiwa zvehunyanzvi mukugadzirwa kwegraphitized petroleum coke, hapana mabhizinesi akawanda ekugadzira uye kumanikidzwa kushoma pari zvino, saka kutaura zvazviri, musika wakakura, kuwanikwa kudiki, uye kuwanikwa kwese kuri kushoma pane kudiwa.
Parizvino, mamiriro ezvinhu mumusika wepetroleum coke muChina ndeekuti, zvinhu zvakawanda zvine sarufa petroleum coke zvakawandisa, zvinonyanya kushandiswa semafuta; zvinhu zvishoma zvine sarufa petroleum coke zvinonyanya kushandiswa mukugadzira simbi nekutengesa kunze kwenyika; zvigadzirwa zvepamusoro zve petroleum coke zvinofanirwa kutengeswa kunze kwenyika.
Maitiro ekugadzira calcination yemafuta epetroleum coke ekunze anopedzwa mufekitori, petroleum coke inogadzirwa nefekitori inoenda zvakananga muchikamu checalcination kuti iite calcination.
Sezvo pasina mudziyo we calcination mumafekitori emumba, petroleum coke inogadzirwa nemafekitori inotengeswa zvakachipa. Parizvino, petroleum coke ne coal calcining zvekuChina zviri kuitwa muindasitiri yesimbi, senge carbon plant, aruminiyamu plant, nezvimwewo.
