Petroleum coke carburizer. Nyob rau hauv no txoj kev, roj av coke yuav zoo dua decomposed nyob rau hauv molten hlau. Lub ntsiab carburizer ntawm kev ua lag luam tam sim no yog graphitized roj av coke carburizer.
Muaj ntau yam khoom siv raw rau cov neeg ua haujlwm carburizing, thiab cov txheej txheem tsim tawm kuj txawv, suav nrog cov pa roj carbon monoxide, cov pa roj carbon monoxide, coke, graphite, thiab lwm yam, ntawm cov uas muaj ntau hom me me hauv ntau pawg. Carburizers uas ua tau zoo dua feem ntau yog xa mus rau carburizers uas tau graphitized. Nyob rau hauv qhov kub thiab txias, qhov kev npaj ntawm carbon atoms siv lub microscopic daim ntawv ntawm graphite, yog li nws yog hu ua graphitization.
Kev cuam tshuam ntawm qhov loj me ntawm tus neeg saib xyuas carburizing: Tus nqi nqus ntawm tus neeg sawv cev carburizing nyob ntawm qhov sib xyaw ua ke ntawm kev sib xyaw thiab qhov sib txawv ntawm tus neeg sawv cev carburizing thiab oxidation poob tus nqi. Nyob rau hauv ib txwm muaj, cov carburizer hais me me, tus nqi tawg yog ceev, thiab tus nqi poob yog loj; cov carburizer hais yog loj, tus nqi dissolution qeeb, thiab tus nqi poob yog me me. Kev xaiv ntawm carburizer particle loj yog cuam tshuam nrog txoj kab uas hla thiab lub peev xwm ntawm lub cub tawg.
Feem ntau hais lus, yog tias txoj kab uas hla thiab lub peev xwm ntawm lub cub tawg loj, qhov loj me ntawm lub carburizer yuav tsum loj dua; conversely, particle loj ntawm lub carburizer yuav tsum me me.
