Pfupiso
1. Maonero akajairika
Graphitization: kugona kuburitsa zvinhu pakati pegore rinouya
Zvinhu zvakagadzirwa: makore maviri anotevera anotarisirwa kuva nekushanduka-shanduka kwakanyanya
2. Musiyano nekushandiswa kwecoke yenenjere yemarasha necoke yemafuta:
Zvinhu zvakasiyana-siyana: matope emafuta akagadzirwa nemafuta, asphalt yemarasha yakagadzirwa nemarasha.
Mashandisirwo akasiyana: coke yenenjere yemafuta, coke yenenjere yemarasha inoshandiswa paelectrode ine simba guru (ultra); coke yenenjere yemafuta isina kugadzirwa uye yakabikwa paelectrode isina kugadzirwa.
Kufambira mberi: Marasha anogona kukura mune ramangwana.
3. Maitiro ekuwanikwa uye kudiwa kwepetroleum coke: nzira nhatu dzekushandisa electrode iri pasi pemvura + anode yakabikwa kare + electrode isina kunaka dziri kuwedzera, nepo divi rekupihwa risingawedzere kugadzirwa kana kutoderedza huwandu, zvichikonzera mitengo yakakwira uye zvigadzirwa zvinotengeswa kunze kwenyika zvingasakwanise kugutsa kudiwa kwacho.
4. Kuwedzerwa kwenzvimbo yeAnode kumusoro: Zhongke Electric neAnqing Petrochemical vakasaina chibvumirano chekushandira pamwe, asi hapana kubatanidzwa kwechokwadi kwemari kana kudyara mari.
5. Chiyero checoke chisina kunaka: chepamusoro-soro chine needle coke yakachena, chakasanganiswa pakati, pasi-soro chine petroleum coke yakachena. Needle coke 30-40%, petroleum coke 60-70%. Tani yeelectrode isina kunaka ine petroleum coke yakachena matani 1.6-1.7.
6. Kuenderera mberi kwegirafiti: kufambira mberi kuripo parizvino hakuna kunaka, kwakafanana neindasitiri yediaphragm, asiwo kuvimba nemidziyo kuti irambe iripo, kubudirira mune ramangwana kunogona kuderedza kushandiswa kwesimba uye mazuva ekutumira.
Mibvunzo neMhinduro
1. Kuwanikwa uye kudiwa uye mutengo
Mubvunzo: Kuwanikwa uye kudiwa uye kushomeka kwemitengo yekoka ine sulfur yakaderera?
A: Matani miriyoni imwe chete ecoke ine sulfur shoma achatumirwa gore rino, zvichiita kuti ive 60%. Nekugohorera kwe60%, 60/0.6=matani miriyoni imwe chete ecoke ine sulfur shoma achadiwa. Kudiwa kunopfuura kuwanikwa, zvichikonzera kukwira kwemitengo, uye mutengo unodarika 8000 yuan.
Mubvunzo: Maitiro egore rinouya ekugovera nekudiwa, mamiriro emitengo?
A: Koke ine sulfur shoma (common petroleum coke) ine mashandisirwo matatu: electrode, anode yakabikwa kare uye negative electrode. Dzese dziri kukura. Rutivi rwekugovera haruna kuwedzera kana kuderedza kugadzirwa, zvichikonzera mitengo yakakwira.
Mubvunzo: Makambani ekokeji yekota yechipiri ane kukwira kwemitengo, kune kuderera kwekutapurirana kwemitengo
A: Ningde Times neBYD havazotori mutoro wakazara, asi vachatora chikamu chawo. Fekitori ye cathode ichatora chikamu chawo. Fekitori yebhatiri yechipiri inogona kuitisa. Tarisa purofiti chaiyo patani, pamwe chete ne graphitization ratio, mutengo we coke hausi pachena zvakanyanya.
Q: Chii chinonzi amplitude yezvinhu zvisina kunaka zveQ2 paavhareji?
A: Kadiki, 10%, graphitization isina kuchinja, Q1 low sulfur coke inenge 5000 yuan, Q2 avhareji 8000 yuan,
Mubvunzo: Maonero ekuwanikwa uye kudiwa kwemafuta epetroleum coke
A: (1) Kudiwa kwemuno kunopfuura kuwanikwa: kukura kwepasi pevhu ndiko kunokurumidza, kukura kwe40%+ kwepetroleum coke, petroleum coke mumakore maviri anotevera zviri mukushamisika kukuru, nekuti petrochina yemuno, kuwedzera kwekugadzirwa kweSinopec kwakaderera, kugadzirwa kwemuno kwematani mamiriyoni makumi matatu pagore, 12% ishoma yesulfur coke, haigone kusangana nezvinodiwa zvemuno.
(2) Kuwedzera kwemafuta ekuwedzera: Tichatorawo coke kubva kuIndonesia, Romania, Russia neIndia. Mukuyedza, kufambira mberi kuri kunonoka, izvo zvingasakwanise kuzadzisa zvinodiwa pakugadzira negative electrode.
(3) Kutonga kwemutengo: mwero wakaderera wegore rapfuura waiva munaKurume, uye petroleum coke yaive 3000 yuan/tani. Mikana yekudzokera kumutengo uyu mudiki.
(4) Nzira yeramangwana: nekuwedzera kwekudiwa kwemotokari dzemagetsi, kushandiswa kwecoke yemafuta kushoma, uye nzira yemarasha inogona kushandiswa.
Mubvunzo: Kokeji yepakati uye kudiwa kwayo?
A: Koke yesarufa yepakati nepakati yakamanikanawo, semuenzaniso, matani miriyoni imwe eanode, kurasikirwa kwe10% kwegraphitization, matani miriyoni imwe chete egraphitization, tani imwe chete yegraphitization inoda matani matatu esulfur coke yepakati nepakati, inoda matani mamiriyoni matatu nematatu esulfur coke yepakati nepakati kuti itsigire.
Mubvunzo: Pane makambani asina kunaka here anopa petroleum coke kumusoro kwerwizi?
A: Zhongke Electric yakasaina chibvumirano chekushandira pamwe neAnqing Petrochemical. Handisati ndambonzwa nezvekubatanidzwa kwechokwadi kwemasheya kana kudyara mari.
Mubvunzo: Musiyano wemitengo uripo pakati pemafekitori madiki nemafekitori makuru akadai seShanshan neKaijin ndeupi?
A 
1) indasitiri yezvakaipa haigone kungoverenga mutsauko wemitengo. Kune chigadzirwa chimwe chete kana zviviri zvakajairika muindasitiri yezvakaipa, zvizhinji zvacho zviri zvigadzirwa zvemunhu.
(2) Mafekitori madiki haana zvakanakira muzvigadzirwa zvakajairika, saka anofanira kudzikisa mitengo kuti akwane musika. Kana mafekitori madiki akaunganidza tekinoroji uye akadzidza zvigadzirwa zvepamusoro uye zvigadzirwa zvakagadzirwa nemunhu, anogona kugadzira zvakanakira. Kana mafekitori makuru asingaite zvigadzirwa zvakagadzirwa nemunhu, anogona chete kuita zvigadzirwa zvakajairika.
2, kupatsanura uye kushandisa petroleum coke
Q: Ndezvipi zvinodiwa zve coke yezvinhu zvepamusoro zvemapango akasiyana-siyana asina kunaka?
A: (1) Kupatsanura: kune manyuko mana ecoke isina kunaka, coke ine sarufa shoma yepetroleum, coke ine needle ine mafuta, coke ine needle ine coal, coke ine asphalt yemarasha.
(2) chiyero: coke ine sarufa shoma inoverengerwa 60%, needle coke 20-30%, yasara i coke ine asphalt yemarasha.
Mubvunzo: Chii chinonzi jiao?
A: Inonyanya kupatsanurwa kuita petroleum nemarasha, mafuta anogona kupatsanurwa kuita petroleum coke yakajairika, needle coke; Marasha anogona kupatsanurwa kuita coke yakajairika, needle coke, asphalt coke

Mubvunzo: Pane mukana here wekuti vatengesi vaite negative pole, senge Socom?
A 1) suotong inotenga matani mamiriyoni mana epetroleum coke pagore, uye indasitiri yese isina kunaka inotenga matani miriyoni imwe chete, ayo akapetwa ka4. Ine mukana wehuwandu. Kune vanhu vashoma vanobatana zvakananga neCNPC ne sinopec, kunyanya vatengesi, nekuti kutengeserana kunonyanya kukurukurwa.
(2) mafambiro emitengo yeindasitiri: indasitiri yemafuta ecoke pakutanga kwegore nekupera kwemutengo wakakwira, nekuti kuti zvinhu zviwedzere, muna Chivabvu naChikumi, mafuta ecoke esulfur akaderera, epakati nepakati akadonha ne10-15%, nekuda kwehuwandu hwezvinhu zvakachengetwa, muna Gumiguru ndokutanga kuunganidzwa, mutengo uchakwira zvakare.
Mubvunzo: Vagadziri vemafuta asina kunaka vachatenga petroleum coke zvakananga here? Ko Sotone inobatsira papi?
A: Mazhinji acho achiri kutengwa kubva kuvatengesi. Huwandu hwacho hudiki zvekuti hahukwanise kutengeswa neCNPC neSinopec. Sulphur coke dzese dziri mbiri, dzepakati nedzepasi dzinogadzirwa.
5, graphite yekugadzira uye graphite yechisikigo
Mubvunzo: Kushandisa girafiti yechisikigo
A 1) mazhinji acho anoshandiswa kunze kwenyika. Magetsi eLG anoshandisa hafu yekugadzira uye hafu yechisikigo. Mafekitori makuru emumba B neC anoshandisawo chikamu chechisikigo, chinova 10%
(2) zvikanganiso zvegirafiti yechisikigo: girafiti yechisikigo isina kugadziriswa ine matambudziko akawanda, akadai sekuwedzera kukuru, kutadza kufamba zvakanaka kweropa.
(3) Kufunga nezvemafashoni: kana chigadzirwa chemhando yepamusoro chikashandiswa zvishoma nezvishoma muChina, zvinokurudzirwa kuti chishandiswe kubva mumotokari dzemhando yepamusoro. Zvichava nyore kuva nematambudziko nemotokari dzemhando yepamusoro dzakasanganiswa zvakananga ne20-30%.
Mubvunzo: Ndeupi musiyano uripo pakati pegirafiti yechisikigo negirafiti yekugadzira?
A: Graphite yechisikigo yatova graphite muvhu. Mushure mekusakura, inova graphite yakarongwa. Kana yapetwa, inova bhora regraphite rechisikigo.
Zvakanakira: yakachipa zvishoma, ine simba guru (360GWH), ine simba rakawanda;
Zvakashata: kusashanda zvakanaka kwebhasikoro, kuwedzera kuri nyore, kusashanda zvakanaka kwekupisa kwakanyanya
Mubvunzo: Ko tekinoroji ye graphite anode yakagadzirwa yakapararira here zvekuti munhu wese anogona kugadzira zvigadzirwa zvakafanana?
A: Ichokwadi kuti kune kupararira kwetekinoroji. Iye zvino kune zvirimwa zvidiki zvakawanda. Kubva pakati pegore rapfuura kusvika pari zvino, chirimwa chisina kunaka chakaburitsa matani mamiriyoni matanhatu kusvika manomwe.
(1) Pane kuverenga kaviri. Matani 300,000 ezvigadzirwa zvakapedzwa uye matani 100,000 egraphitization akashandiswa. Data rese rakakura.
