Needle coke rudzi rwemhando yepamusoro rwakagadzirwa nesimba muzvinhu zvekabhoni. Chitarisiko chayo chakasimba chine maburi ane grey yesirivha uye simbi inopenya. Chimiro chayo chine magadzirirwo anoyerera zviri pachena, ine maburi makuru asi mashoma uye chimiro cheoval zvishoma. Ndiyo midziyo yekugadzira zvigadzirwa zvekabhoni zvepamusoro-soro zvakaita se ultra-high power electrode, special carbon material, carbon fiber nezvimwe zvinhu zvayo.
Zvichienderana nezvinhu zvakasiyana-siyana, needle coke inogona kukamurwa kuita oil needle coke uye coal needle coke. Needle coke inogadzirwa kubva mumafuta akasara ioil needle coke. Needle coke inogadzirwa kubva mucoal tar pitch uye chikamu chayo icoal series needle coke.
Ma indekisi anokanganisa kunaka kwe needle coke anosanganisira true density, sulfur content, nitrogen content, volatile matter, ash content, thermal expansion coefficient, resistivity, vibration density, nezvimwewo. Nekuda kwe index coefficient yakasiyana, needle coefficient inogona kukamurwa kuita super grade (giredhi rakanaka), first grade nesecond grade.
Musiyano wekushanda pakati pe coke yemarasha ne oil needle coke unosanganisira zvinotevera.
1. Mumamiriro ezvinhu akafanana, electrode yegrafiti yakagadzirwa neoil needle coke iri nyore kugadzira kupfuura coal needle coke.
2. Mushure mekugadzira zvigadzirwa zvegrafiti, huwandu uye simba rezvigadzirwa zvegrafiti zveoil-series needle coke zvakakwirira zvishoma pane zvecoal-series needle coke, izvo zvinokonzerwa nekuwedzera kwecoal-series needle coke panguva yegraphitization.
3. Mukushandiswa kwakananga kwe graphite electrode, chigadzirwa che graphitized che oil needle coke chine coefficient yakaderera yekuwedzera kwekupisa.
4. Panyaya yezviratidzo zve graphite electrode, simba rekushandisa graphite yakagadzirwa ne oil needle coke rakakwira zvishoma pane re coal needle coke product.
5. Chinonyanya kukosha ndechekuti coke yemarasha inoyera needle coke inowedzera kana tembiricha yasvika 1500-2000 ℃ mukuita graphitization yekupisa kwakanyanya, saka mwero wekukwira kwetembiricha unofanirwa kudzorwa zvakanyanya, kwete kukurumidza kukwira kwetembiricha, zvakanaka kusashandisa series graphitization process production, coke yemarasha inoyera nekuwedzera zvimwe zvinhu kudzora kuwedzera kwayo, mwero wekuwedzera unogona kuderedzwa. Asi zvakaoma kuwana oil needle coke.
6. Calcined oil needle coke ine coke diki uye saizi yezvidimbu zvidiki, nepo coal needle coke ine huwandu hushoma uye saizi yezvidimbu zvikuru (35 — 40 mm), izvo zvinogona kusangana nezvinodiwa zvehukuru hwezvidimbu zvefomula, asi zvinounza matambudziko kune vashandisi.
7. Sekuburitswa kweJapan Petroleum Coke Company, zvinofungidzirwa kuti musanganiswa weoiri needle coke uri nyore kupfuura coal needle coke, saka zviri nyore kudzora coking nenguva yekupisa.
Kubva pane zvataurwa pamusoro apa, oil needle coke ine mana akaderera: low false false specific gravity, low strength, low CTE, low specific resistance, zvinhu zviviri zvekutanga zvinodzikira kusvika kugraphite, zvigadzirwa zviviri zvekupedzisira zvinodzikira kusvika kugraphite zvakanaka. Kazhinji, performance indexes ye oil series needle coke iri nani pane coal series needle coke, uye application yacho inodawo zvakawanda.
Parizvino, graphite electrode ndiyo inonyanya kudiwa pamusika we needle coke, ichitora chikamu chinosvika 60% chekushandiswa kwe needle coke, nepo makambani e electrode aine kudiwa kwakajeka kwe needle coke, pasina kudiwa kwemhando yepamusoro. Kudiwa kwe needle coke yezvinhu zve lithium ion battery anode kwakawanda, musika wedhijitari wepamusoro unonyanya kufarira coke yakabikwa nemafuta, musika wemagetsi ebhatiri unonyanya kutsamira pa coke ine mashandiro akakwira.
Kugadzirwa kweNeedle coke kune mwero wehunyanzvi, saka mabhizinesi emuno haawanzo kuwanikwa. Parizvino, mabhizinesi makuru ekugadzira mafuta eNeedle coke anosanganisira: Weifang Fumei new Energy, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei new energy, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, nezvimwewo. Makambani makuru ekugadzira needle coke eBaowu carbon material, Baotailong technology, Anshan open carbon, Anshan Chemical, Fang Daxi ke Mo, Shanxi Macro, Henan open carbon, Xuyang Group, Zaozhuang revitalization, Ningxia Baichuan, Tangshan Dongri new energy, Taiyuan Shengxu nezvimwewo.
