Calcined roj av coke feem ntau yog siv rau hauv pre-baked anode thiab cathode rau electrolytic txhuas, recarburizer rau metallurgical thiab hlau kev lag luam ntau lawm, graphite electrode, industrial silicon, daj phosphorus thiab carbon electrode rau ferroalloy, thiab lwm yam.
Yog li ntawd, ob qho tib si electrolytic txhuas cog, cov nroj tsuag carbon ywj pheej thiab cov chaw ua roj av them sai sai rau kev nce qib thiab kev txhim kho ntawm cov thev naus laus zis calcination roj av coke.
Pom tias cov roj av calcined muaj ntau lub luag haujlwm, nws yog qhov tsim nyog los tsim cov txuj ci tsim khoom tshiab los txhim kho kev siv cov roj av calcined ntxiv.
Tshwj xeeb tshaj yog, lub cub tawg calcining rau kev tsim cov roj av coke calcined hauv Suav teb tseem muaj qhov chaw zoo rau kev txhim kho txuj ci. Nws yog qhov tsim nyog los tsom mus rau kev siv cov ntaub ntawv tshiab, kev tsim cov cib silica zoo, kev rov qab los ntawm cov peev txheej kub pov tseg hauv ntau txoj kev, kev txhim kho kev ua haujlwm tsis siv neeg, lub cub tawg ziab thiab kev ua haujlwm txheem, kom ua rau kev siv cov roj av coke calcined siab dua.
Qhov siv tau zoo dua, ntxiv rau qhov cub tawg kom txhim kho lub neej kev loj hlob, kev tsim khoom siab, kev tiv thaiv ib puag ncig ntse, kev lag luam kev lag luam.
Tshwj xeeb, nws yog qhov tsim nyog los ua ke cov thev naus laus zis simulation nrog kev xyaum tsim khoom los txhim kho qhov zoo thiab cov teeb meem kev siv tshuab ntawm Tuam Tshoj cov roj av calcined, yog li kom txo qis tus nqi tsim khoom thiab txhim kho kev ua haujlwm ntau lawm.
Qhov feem pua ntawm cov qauv nqi calcined tar hauv Suav teb
Hauv cov graphite electrode siv rau hauv steelmaking lossis anode paste (melting electrode) siv rau hauv txhuas thiab magnesium, txhawm rau kom ua tau raws li qhov yuav tsum tau ua ntawm roj av coke (coke), coke yuav tsum tau calcined.
Qhov kub ntawm calcination feem ntau yog nyob ib puag ncig 1300 ℃, nrog lub hom phiaj ntawm kev tshem tawm cov volatiles ntawm tar ntau li ntau tau.
Ua li no, cov ntsiab lus hydrogen ntawm cov roj av coke reproducts tuaj yeem txo qis, qib graphitization ntawm roj av coke tuaj yeem txhim kho, thiab lub zog kub siab thiab kev tiv thaiv cua sov ntawm graphite electrode tuaj yeem txhim kho, thiab cov hluav taws xob conductivity ntawm graphite electrode tuaj yeem txhim kho.
Kev hlawv calcined feem ntau yog siv rau hauv kev tsim cov graphite electrode, cov khoom siv carbon paste, xuab zeb pob zeb diamond, kev lag luam phosphorus zaub mov, kev lag luam metallurgical thiab calcium carbide, ntawm cov graphite electrode yog qhov siv dav tshaj plaws.
Cov coke nyoos tuaj yeem siv ncaj qha rau calcium carbide ua cov khoom tseem ceeb, silicon carbide thiab boron carbide ua cov ntaub ntawv sib tsoo yam tsis muaj kev sib tsoo thiab hlawv.
Kuj tseem siv tau ncaj qha ua cov cib ua los ntawm cov hlau ua los ntawm cov cua sov coke lossis cov cua sov ua los ntawm cov pa roj carbon, kuj tseem siv tau ua cov txheej txheem casting rau cov coke ntom ntom, thiab lwm yam.
Daim ntawv tshaj tawm xyoo 2020-2026 Tuam Tshoj calcined petrolem coke kev tshawb fawb txog kev lag luam tob ntawm qhov xwm txheej tam sim no thiab kev hloov pauv ntawm daim ntawv tshaj tawm kev txhim kho "yog raws li ntau qhov kev tshawb fawb kev lag luam, feem ntau yog raws li Lub Chaw Haujlwm Saib Xyuas Kev Txheeb Xyuas Hauv Tebchaws, Ministry of Commerce thiab National Development and Reform Commission, Lub Chaw Tshawb Fawb Txog Kev Txhim Kho ntawm Lub Xeev, Lub Koom Haum Kev Lag Luam calcined coke, cov ntaub ntawv tshaj tawm txog calcined coke hauv tsev thiab txawv teb chaws, thiab lub hauv paus ntawm cov chaw tshawb fawb txog kev lag luam calcined coke los muab cov ntaub ntawv ntxaws ntxaws,
Ua ke nrog cov ntaub ntawv tshawb fawb txog kev lag luam tob tob, raws li kev cuam tshuam tam sim no ntawm Tuam Tshoj txoj kev lag luam loj, cov cai thiab cov lag luam tseem ceeb rau kev lag luam coke, daim ntawv no tsom mus rau kev ua haujlwm tag nrho ntawm kev lag luam coke thiab cov lag luam me cuam tshuam, thiab tshuaj xyuas thiab kwv yees qhov kev txhim kho thiab kev cia siab ntawm kev lag luam coke yav tom ntej.
Daim ntawv tshaj tawm txog qhov xwm txheej tam sim no thiab kev txhim kho ntawm Tuam Tshoj kev lag luam calcined coke txij xyoo 2020 txog 2026 uas tau tso tawm los ntawm kev tshawb fawb kev lag luam muaj cov ntaub ntawv raws sijhawm thiab tiav, cov duab kos nplua nuj thiab kev xav paub. Raws li kev tshuaj xyuas tob thiab kev kwv yees ntawm qhov xwm txheej tam sim no thiab kev txhim kho ntawm kev lag luam calcined coke, kev cia siab yav tom ntej ntawm kev lag luam calcined coke tau raug kawm.
Rau cov tuam txhab ua lag luam calcining coke hauv kev sib tw ua lag luam tam sim no, kev nkag siab txog kev nqis peev, kev hloov kho tsim nyog ntawm txoj kev lag luam;
Yuav kom xaiv tau lub cib fim zoo rau cov neeg ua lag luam uas muaj lub tswv yim zoo, cov thawj coj ntawm lub tuam txhab yuav ua cov kev npaj tswv yim zoo, muab cov ntaub ntawv txog kev lag luam thiab cov lus qhia tsim nyog.
"Xyoo 2020-2026 Tuam Tshoj calcined coke kev lag luam hauv kev tshawb fawb tob thiab kev txhim kho daim ntawv qhia" yog daim ntawv qhia kev tshaj lij tseem ceeb rau cov tuam txhab calcined coke, cov chaw tshawb fawb, cov tsev txhab nyiaj, tsoomfwv, thiab lwm yam, kom nkag siab meej, nkag siab sai sai txog kev txhim kho tam sim no ntawm kev lag luam calcined coke thiab nkag siab txog kev taw qhia kev txhim kho ntawm cov tuam txhab.
