Calcined Petroleum Coke rau Steel Production

• Calcined petroleum coke (CPC) yog ib qho tseem ceeb ntawm cov txheej txheem tsim cov hlau. CPC yog tsim los ntawm ntsuab petroleum coke (GPC), uas yog ib tug by-product ntawm crude roj refining. Cov txheej txheem calcination tshem tawm cov tshuaj tsis haum xws li cov dej noo thiab cov hydrocarbons los ntawm GPC, tawm hauv cov khoom siv roj carbon monoxide uas zoo tagnrho rau siv hauv hluav taws xob arc furnaces (EAFs) thiab blast furnaces.
• Hauv kev tsim cov hlau, CPC feem ntau yog siv los ua cov pa roj carbon ntxiv los kho cov ntsiab lus ntawm cov hlau. Qhov sib ntxiv ntawm CPC rau steel txhim kho cov khoom siv ntawm cov hlau, xws li lub zog thiab hardness. CPC kuj tseem siv los ua tus txo qis hauv kev tsim cov ferroalloys thiab lwm yam hlau thiab ua roj hauv kev lag luam cement.
• Qhov zoo ntawm CPC yog qhov tseem ceeb los xyuas kom meej tias kev ua haujlwm zoo ntawm EAFs thiab blast furnaces. Cov ntsiab lus carbon, cov ntsiab lus tshauv, cov ntsiab lus ntawm leej faj, thiab qhov loj me me faib tag nrho ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm CPC hauv kev tsim cov hlau. Cov neeg tsim khoom ntawm CPC yuav tsum ua raws li cov qauv kev tswj hwm nruj kom ntseeg tau tias lawv cov khoom ua tau raws li cov lus qhia tshwj xeeb uas tsim los ntawm cov neeg tsim khoom steel.

Calcined petroleum coke (CPC) muaj nyob rau hauv ntau qhov ntau thiab tsawg los yog granulometries kom tau raws li cov kev cai sib txawv hauv kev tsim steel.

CPC feem ntau ntim rau hauv hnab loj lossis hnab jumbo.

Calcined petroleum coke muaj ntau yam zoo uas ua rau nws nyiam xaiv hauv ntau daim ntawv thov:

• Cov ntsiab lus siab carbon:CPC muaj cov ntsiab lus siab carbon, feem ntau siab dua 97%. Cov ntsiab lus carbon siab no ua rau nws muaj txiaj ntsig zoo carbon additive, muab cov qib carbon uas xav tau hauv cov hlau thiab lwm yam kev siv.
• Tsawg Volatile Matter:Calcination ntawm roj av coke txo nws cov ntsiab lus tsis hloov pauv, ua rau CPC qis hauv cov ntaub ntawv tsis hloov pauv. Cov teeb meem tsis hloov pauv tsawg yog qhov tseem ceeb rau kev txo qis emissions thiab ua tiav kev ua tau zoo ib yam hauv cov ntawv thov xws li steelmaking.
• Txhim kho Physical thiab Chemical Properties:Cov txheej txheem calcination txhim kho lub cev thiab tshuaj lom neeg ntawm cov roj av coke, xws li nce ceev, hluav taws xob conductivity, thiab thermal conductivity. Cov cuab yeej txhim kho no pab txhawb kev ua haujlwm zoo dua hauv kev siv xws li anode ntau lawm thiab steelmaking.
• Tsawg Sulfur Cov ntsiab lus:CPC feem ntau muaj cov ntsiab lus tsis tshua muaj leej faj, uas muaj txiaj ntsig zoo rau cov ntawv thov uas yuav tsum muaj cov qib sulfur tsawg, xws li cov hlau ntau lawm. Cov ntsiab lus sulfur tsawg pab txo qis impurities thiab txhim kho qhov zoo ntawm cov khoom kawg.
