Lub luag hauj lwm ntawm graphitized roj av coke nyob rau hauv steel furnace ironmaking yog muab cov pa roj carbon qhov chaw rau cov txheej txheem hlau. Cov pa roj carbon nyob rau hauv graphitized roj av coke ua raws li kev txo tus neeg sawv cev, reacting nrog cov pa oxygen hauv cov hlau ore los tsim cov pa roj carbon monoxide, uas txo cov hlau ore kom molten hlau. graphitized petroleum coke kuj pab ua kom cov pa roj carbon ntsiab lus ntawm cov khoom kawg, ua rau nws hardness, lub zog thiab durability.
Qhov zoo ntawm kev siv graphitized petroleum coke nyob rau hauv steel furnace ironmaking muaj xws li:
1. Cov ntsiab lus siab carbon: graphitized petroleum coke muaj cov ntsiab lus siab carbon, txog li 98% mus rau 99.9%, thiab yog cov pa roj carbon zoo tagnrho hauv cov txheej txheem hlau.
2. Tsawg impurity cov ntsiab lus: graphitized petroleum coke muaj cov ntsiab lus impurity tsawg, tshwj xeeb tshaj yog leej faj thiab nitrogen, uas yog unfavorable rau lub ironmaking txheej txheem.
3. High thermal conductivity: graphitized petroleum coke muaj cov thermal conductivity siab, uas pab faib cov cua sov sib npaug hauv lub cub tawg, thiab cov khoom zoo dua.
4. Cov ntsiab lus tsis tshua muaj tshauv: graphitized petroleum coke muaj cov hmoov tshauv tsawg, uas txo cov slagging thiab txhim kho qhov cub ua haujlwm.
5. Tus nqi qis: graphitized petroleum coke yog tus nqi ntau dua li lwm cov ntaub ntawv carbon xws li anthracite thiab metallurgical coke. Hauv cov ntsiab lus, daim ntawv thov ntawm graphitized roj av coke nyob rau hauv steel furnace ironmaking yog qhov tseem ceeb rau kev tsim cov hlau zoo. Nws cov ntsiab lus carbon siab, tsis muaj impurity cov ntsiab lus, siab thermal conductivity, cov ntsiab lus tsis tshua muaj tshauv thiab tus nqi qis ua rau nws yog qhov zoo tshaj plaws carbon qhov chaw rau cov txheej txheem no.
Yog lawm, muaj lwm yam zoo rau kev siv graphitized petroleum coke (graphitized petroleum coke) nrog rau nws daim ntawv thov hauv steel furnace ironmaking.
1. Roj qhov chaw: graphitized petroleum coke tuaj yeem siv los ua cov khoom siv roj rau ntau yam kev lag luam xws li cement thiab hluav taws xob. Nws cov nqi calorific siab, cov ntsiab lus tsis muaj leej faj thiab cov hmoov tshauv tsawg ua rau nws xaiv cov roj rau kev lag luam.
2. Hluav taws xob conductivity: graphitized petroleum coke muaj cov khoom siv hluav taws xob zoo heev vim nws cov ntsiab lus carbon siab, uas ua rau nws cov khoom tsim nyog rau electrodes, anodes, thiab cathodes hauv ntau daim ntawv thov, suav nrog electrolysis, aluminium ntau lawm, thiab lithium-ion roj teeb.
3. Chemical Purity: graphitized petroleum coke muaj cov tshuaj purity siab ua rau nws zoo tagnrho rau kev siv tshuaj xws li catalysts, roj hlwb thiab hluavtaws pob zeb diamond ntau lawm.
4. Cov peev txheej txuas dua tshiab: graphitized petroleum coke yog tsim los ntawm cov roj av coke, cov khoom siv los ntawm cov roj av refining. Yog li ntawd, graphitized petroleum coke yog cov khoom siv txuas ntxiv dua tshiab uas pab txo cov khib nyiab thiab ua kom muaj kev ruaj ntseg.
5. Ib puag ncig me me: Piv nrog rau lwm cov ntaub ntawv carbon xws li thee, graphitized petroleum coke muaj qhov cuam tshuam me me rau ib puag ncig. Nws cov khoom tsim tawm tsawg dua carbon dioxide emissions thiab cov pa phem, ua rau nws muaj kev xaiv zoo rau ib puag ncig.
