Koob coke yog ntau yam zoo heev uas tsim los ntawm cov ntaub ntawv carbon.Nws cov tsos yog cov khoom ntxeem tau nrog nyiaj grey thiab xim hlau luster.Nws cov qauv muaj qhov pom tseeb ntws zoo nkauj, nrog loj tab sis ob peb qhov thiab me ntsis oval zoo li.Nws yog cov khoom siv raw rau cov khoom siv high-end carbon xws li ultra-siab zog electrode, cov khoom siv tshwj xeeb carbon, carbon fiber thiab nws cov khoom sib xyaw.
Raws li cov khoom sib txawv, rab koob coke tuaj yeem muab faib ua roj koob coke thiab thee koob coke.Koob coke ua los ntawm roj av residue yog roj koob coke.Cov koob coke uas ua los ntawm cov thee tar suab thiab nws cov feem yog coal series koob coke.
Cov indexes uas cuam tshuam rau qhov zoo ntawm rab koob coke muaj xws li qhov tseeb ntom ntom, cov ntsiab lus sulfur, cov ntsiab lus nitrogen, cov ntsiab lus tsis zoo, cov ntsiab lus tshauv, thermal expansion coefficient, resistivity, vibration ntom, thiab lwm yam. qib super (qib zoo heev), qib thawj thiab qib thib ob.
Qhov kev ua tau zoo sib txawv ntawm cov thee thiab roj koob coke suav nrog cov ntsiab lus hauv qab no.
1. Raws li cov xwm txheej zoo ib yam, cov graphite electrode ua los ntawm cov roj koob coke yog qhov yooj yim dua rau cov duab zoo dua li cov koob koob coke.
2. Tom qab ua cov khoom lag luam graphite, qhov ntom thiab lub zog ntawm cov khoom siv graphitized ntawm cov roj-series koob coke yog me ntsis siab dua li ntawm cov thee-series koob coke, uas yog tshwm sim los ntawm kev nthuav dav ntawm thee-series koob coke thaum graphitization.
3. Hauv kev siv cov graphite electrode tshwj xeeb, cov khoom graphitized ntawm cov roj koob coke muaj qis coefficient ntawm thermal expansion.
4. Nyob rau hauv cov nqe lus ntawm lub cev thiab tshuaj indexes ntawm graphite electrode, qhov tshwj xeeb kuj ntawm graphitized khoom ntawm roj koob coke yog me ntsis siab dua li cov coke koob coke khoom.
5. Qhov tseem ceeb tshaj plaws yog qhov ntsuas kub ntawm rab koob coke nthuav dav thaum qhov kub nce mus txog 1500-2000 ℃ nyob rau hauv cov txheej txheem ntawm kev kub siab graphitization, yog li qhov kub nce siab yuav tsum tau tswj nruj me ntsis, tsis ceev kub nce, nws yog qhov zoo tshaj plaws tsis siv cov series graphitization txheej txheem ntau lawm, thee ntsuas koob coke los ntawm kev ntxiv additives los tswj nws expansion, tus nqi expansion yuav txo tau.Tab sis nws yog qhov nyuaj dua kom ua tiav roj koob coke.
6. Calcined roj koob coke muaj ntau me me coke thiab nplua particle loj, thaum thee koob coke muaj tsawg cov ntsiab lus thiab loj particle loj (35 - 40 mm), uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm formula particle loj, tab sis nws coj teeb meem rau cov neeg siv.
7. Raws li kev taw qhia ntawm Nyiv Petroleum Coke Company, nws ntseeg tau hais tias muaj pes tsawg leeg ntawm cov roj koob coke yog yooj yim dua li coke rab koob, yog li nws yooj yim los tswj lub coking thiab cua sov lub sij hawm.
Los ntawm cov saum toj no, roj koob coke muaj plaub yam tsawg: tsawg tsis muaj tseeb lub ntiajteb txawj nqus, tsis tshua muaj zog, tsis tshua muaj CTE, tsis tshua muaj kev tiv thaiv, thawj ob tsawg rau graphite cov khoom, lub xeem ob tsawg rau graphite cov khoom yog haum.Zuag qhia tag nrho, qhov Performance indexes ntawm roj series koob coke yog zoo dua li thee series koob coke, thiab daim ntawv thov kev thov kuj yog ntau dua.
Tam sim no, graphite electrode yog lub lag luam xav tau tseem ceeb rau koob coke, suav txog li 60% ntawm tag nrho daim ntawv thov ntawm koob coke, thaum cov tuam txhab electrode muaj qhov xav tau zoo rau koob coke, tsis muaj tus kheej xav tau.Cov koob coke thov ntawm lithium ion roj teeb anode cov khoom muaj ntau haiv neeg, high-end digital lag luam nyiam cov roj siav coke, lub hwj chim roj teeb lag luam yog nyob ntawm coke nrog cov nqi siab dua.
koob coke ntau lawm muaj ib tug tej yam kev kawm pib, yog li ntawd domestic qhauj kuj tsis tshua muaj.Tam sim no, cov chaw tsim khoom lag luam hauv tsev tseem ceeb ntawm cov roj koob coke suav nrog: Weifang Fumei tshiab Zog, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei lub zog tshiab, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, thiab lwm yam. . Coal series koob coke mainstream ntau lawm enterprises Baowu carbon khoom, Baotailong tshuab, Anshan qhib carbon, Anshan tshuaj, Fang Daxi ke Mo, Shanxi Macro, Henan qhib carbon, Xuyang Group, Zaozhuang revitalization, Ningxia Baiichuan, Tangshan Dongri tshiab zog, Taiyuan Shengxu thiab lwm yam.
