Graphitized petroleum coke carburizer muaj cov yam ntxwv ntawm purity siab, kub tsis kam, thiab siab zog. Nws yog dav siv nyob rau hauv foundry, metallurgy, refractory cov ntaub ntawv thiab lwm yam lag luam. Hauv kev lag luam casting: nws feem ntau yog siv los kho cov qauv thiab hardness ntawm castings thiab txuas lub neej kev pab cuam ntawm castings. Hauv kev lag luam metallurgical: nws plays lub luag haujlwm tseem ceeb thiab tseem ceeb hauv kev smelting steel thiab non-ferrous hlau thiab raws li kev tswj cov khoom hauv steelmaking.
Graphitized petroleum coke carburizer muaj cov pa roj carbon monoxide siab, nqus thiab siv tus nqi, tsis tshua muaj sulfur thiab nitrogen tsawg. Nws tuaj yeem txo qhov pore inclusions, optimize graphite morphology, nce qib spheroidization thiab txhim kho kev ua haujlwm casting, yog li ua tiav lub hom phiaj ntawm kev txhim kho kev lag luam.
Cov txheej txheem carburizing ntawm carburizing tus neeg saib xyuas suav nrog kev tawg, diffusion thiab oxidation poob ntawm tus neeg sawv cev carburizing. Qhov luaj li cas ntawm cov carburizer sib txawv, thiab qhov sib txawv, diffusion thiab oxidation poob tus nqi kuj txawv. 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.
