Cawv Coke yog cov khoom ntawm high - kub kev kho mob ntawm roj av coke. Nws yog qhov tsis tseem ceeb cov khoom siv tseem ceeb hauv kev lag luam xws li txhuas electrolysis, hlau, thiab carbon. Kab lus no tsom rau cov txheej txheem tseem ceeb ntawm kev txwv Coke. Cawv Coke yog tsim los ntawm calcining raw roj coke nyob rau hauv ib lub airtight calcining rauv ntawm 1200 degree, uas nws tau hloov pauv ntawm lub cev thiab tshuaj.
Cov txheej txheem tseem ceeb -} recination:
Lub compination ua yog tsis yog "lub cev qhuav dej thiab ziab" tab sis ib txoj kev hloov pauv nyuaj. Nws cov hom phiaj tseem ceeb thiab cov kev hloov pauv nws cov kev tsis txaus siab suav nrog:
1. Volatile tshem tawm:Raw roj coke coke muaj 8-15% scatile teeb meem (dej thiab lub teeb hydrocarbons). Kev kho kom meej kiag li tshem tawm cov volatiles, txo cov ntsiab lus uas tsis muaj zog ntawm CPC rau hauv qab 0.5%.
2. Lub cev qhuav dej:Tus txheej txheem no kom tshem tawm cov dej ua haujlwm thiab dej saum npoo.
3. Txhim Kho Qhov Tseeb Tseeb:Kev ua kom muaj txiaj ntsig ntawm cov qauv Coke thiab txhim kho nws cov qauv siv lead ua, nce nws qhov tseeb ntawm 1.4-1.6 g / cme (ntsuab coke) rau 2.0-2 Qhov tseeb tiag tiag yog ib qho tseem ceeb tshaj plaws ntawm kev xam pom zoo; Ntau dua ntom feem ntau qhia tau cov khoom zoo dua.
4. Txhim kho cov tshuab zog muaj zog thiab conductivity:Kev ua kom zoo thiab shrinkage ntawm cov qauv siv lead ua yooj yim txhim kho kev kho tshuab zog (hnav thiab zuaj hluav taws xob.
5. Txhim kho cov tshuaj ruaj khov:Siab -} Kev kho kub ua rau nws siv tshuaj ntau ruaj khov thiab tsis tshua muaj tshwm sim.
Cov Khoom Siv Calcination feem ntau suav cov ntsiab lus Qhab, lauj kaub calciners, thiab teb hearth calciners (RKK). Cepred Coke (CPC) yog tus staple ntawm kev lag luam niaj hnub, tshwj xeeb yog cov metallurgical kev lag luam. Los ntawm high - kub recination, nws hloov los ntawm cov roj av los ntawm cov khoom siv siab. Nws qhov zoo yog ncaj qha cuam tshuam nrog qhov zoo ntawm downstream aluminium thiab hlau, kev siv fais fab ntau lawm, thiab ib puag ncig cov pa paug. Yog li ntawd, CPC kev lag luam yog cov ntaub ntawv CPC yog qhov txuas yooj yim txuas nrog lub zog thoob ntiaj teb thiab cov kev cai hlau loj heev thiab cov cai ib puag ncig.
