Nyob rau hauv cov txheej txheem smelting ntawm hlau thiab hlau cov khoom, melting poob ntawm carbon ntsiab nyob rau hauv molten hlau yog feem ntau nce vim muaj tej yam xws li smelting lub sij hawm thiab ntev overheating lub sij hawm, uas ua rau cov carbon cov ntsiab lus nyob rau hauv molten hlau tsis tuaj yeem ncav cuag tus nqi theoretical xav tau. kho kom zoo.
Txhawm rau ua kom muaj cov pa roj carbon ntau hauv cov txheej txheem smelting ntawm cov hlau thiab hlau, cov pa roj carbon monoxide ntxiv yog hu ua carburizer.
Petroleum coking tus neeg sawv cev tuaj yeem siv rau hauv cov hlau cam khwb cia hlau, cov ntsiab lus carbon feem ntau yog 96 ~ 99%.
Muaj ntau ntau hom carburizing tus neeg sawv cev raw cov ntaub ntawv, carburizing tus neeg sawv cev tsim cov txheej txheem ntau lawm kuj txawv, muaj ntoo carbon, thee carbon, coke, graphite, thiab lwm yam.
High quality carburizer feem ntau yog hais txog graphitized carburizer, nyob rau hauv qhov kub thiab txias, qhov kev npaj ntawm carbon atoms qhia lub microscopic morphology ntawm graphite.
Graphitization tuaj yeem txo cov ntsiab lus ntawm impurities hauv carburizer, nce cov ntsiab lus carbon ntawm carburizer thiab txo cov ntsiab lus sulfur.
Muaj ntau ntau hom carburizer, thiab qhov Performance index ntawm carburizer zoo ib yam. Cov hauv qab no yog txoj hauv kev kom paub qhov zoo ntawm carburizer:
1. Cov ntsiab lus dej: Cov dej ntsiab lus ntawm carburizer yuav tsum tsawg li tsawg tau, thiab cov ntsiab lus dej yuav tsum tsawg dua 1%.
2. Cov ntsiab lus tshauv: Cov hmoov tshauv ntawm carburizer yuav tsum tsawg li tsawg tau. Cov hmoov tshauv ntawm calcined petroleum coke carburizer yog qhov tsawg, txog 0.5 ~ 1%.
3, volatilization: volatilization yog qhov tsis muaj txiaj ntsig ntawm carburizer, volatilization nyob ntawm qhov kub thiab txias ntawm lub carburizer thiab cov txheej txheem kho, kev ua tiav carburizer volatilization yog qis dua 0.5%.
4. Cov pa roj carbon monoxide ruaj khov: Cov pa roj carbon monoxide ruaj khov ntawm lub carburizer yog qhov tseem ceeb ntawm cov carburizer, qhov siab dua cov pa roj carbon monoxide, qhov zoo dua.
Raws li tus nqi ruaj khov ntawm cov carburizer, carburizer tuaj yeem muab faib ua ntau qib, xws li 95%, 98.5%, 99%, thiab lwm yam.
5. Cov ntsiab lus ntawm cov sulfur: cov ntsiab lus ntawm cov sulfur ntawm carburizer yog ib qho tseem ceeb ntawm cov khoom tsis zoo, thiab cov nqi qis dua, qhov zoo dua. Cov ntsiab lus ntawm sulfur ntawm carburizer nyob ntawm seb cov ntsiab lus ntawm cov khoom siv raw ntawm carburizer thiab calcining kub
