- Particle loj:Qhov loj me me ntawm carburizer muaj kev cuam tshuam zoo rau nws qhov nqus tau. Cov particle loj dhau lawm, nws tsis yooj yim rau kev sib cuag nrog cov kua hlau thaum melting, thiab tus nqi nqus tau txo; Cov khoom me me dhau lawm thiab yooj yim rau ntab los yog nqa tawm los ntawm huab cua tam sim no, uas yuav txo qhov nqus tau. Ib qho nruab nrab, qhov loj me me yog feem ntau pom zoo.
- Cov ntsiab lus carbon thiab impurity cov ntsiab lus:Qhov siab dua cov ntsiab lus ntawm cov carburizer, qhov qis dua cov ntsiab lus ntawm impurities (xws li sulfur, nitrogen, tshauv), thiab qhov siab dua nws qhov nqus feem ntau. High quality carburizers muaj ntau dua purity thiab muaj ntau conducive rau nqus.
- Degree ntawm graphitization:Ntuj graphite los yog dag graphitized carburizer, nws tus nqi nqus feem ntau yog siab dua li hom coke lossis coal carburizer, vim tias cov qauv graphitized tau yooj yim absorbed los ntawm cov kua hlau.
2. Smelting txheej txheemtsis muaj(Dab tsi yog qhov cuam tshuam rau qhov nqus ntawm carburizer?)
- Kub:Qhov kub ntawm cov kua hlau ntau dua, qhov siab dua qhov nqus thiab nqus tus nqi ntawm lub carburizer. Qhov no yog vim hais tias lub carburizer yog yooj yim rau decompose ntawm qhov kub thiab txias, thiab cov tshuaj tiv thaiv ntawm carbon nyob rau hauv kev sib cuag nrog kua hlau yog ntau khaus. Txawm li cas los xij, qhov kub thiab txias yuav ua rau kom tsis muaj zog ntxiv.
- Stirring siv:Tsim nyog nplawm tuaj yeem txhim kho kev sib cuag ntawm carburizer thiab cov kua hlau, yog li txhim kho tus nqi nqus. Txawm li cas los xij, kev sib zog ua kom muaj zog heev tuaj yeem ua rau cov carburizer raug tshem tawm hauv cov kua dej thiab ua rau kom poob.
- Ntxiv txoj kev:Lub carburizer feem ntau yog ntxiv rau cov kua hlau los ntawm kev npog txoj kev, txoj kev dispersion los yog embedding txoj kev. Ntawm lawv, txoj kev embedding (ntxiv cov carburizer rau cov kua hlau) feem ntau muaj qhov nqus tau ntau dua vim tias nws tuaj yeem txo oxidation thiab ntab poob.
3. Cov yam ntxwv ntawm cov kua hlau(Dab tsi yog qhov cuam tshuam rau qhov nqus ntawm carburizer?)
- Melt muaj pes tsawg leeg:Qhov concentration ntawm lwm cov ntsiab lus hauv cov kua hlau (xws li oxygen, silicon, sulfur, thiab lwm yam) yuav cuam tshuam rau solubility ntawm carbon. Piv txwv li, silicon thiab carbon tuaj yeem muaj cov txiaj ntsig zoo sib xws, thaum sulfur inhibits kev sib cais ntawm carbon.
- Oxidation:Thaum cov pa oxygen hauv cov kua hlau yog siab, nws yooj yim ua rau oxidation ntawm carburizer rau carbon monoxide los yog carbon dioxide, yog li txo qhov nqus tau.
4. Lub sijhawm ntxiv cov carburizer(Dab tsi yog qhov cuam tshuam rau qhov nqus ntawm carburizer?)
- Ntxiv qhov kub thiab txias:Thaum lub carburizer ntxiv rau hauv lub sijhawm thaum ntxov ntawm melting, tus nqi nqus yuav raug txo vim qhov kub thiab txias tsis txaus thiab cov tshuaj tiv thaiv tsis txaus; Thaum ntxiv rau thaum kawg ntawm melting, cov hlau ua kua kub yog siab dua thiab qhov nqus tau siab dua, tab sis lub sij hawm lig dhau lawm yuav cuam tshuam rau cov khoom sib xws ntawm cov pa roj carbon monoxide.
- Kev noj zaub mov ntu:Yog tias cov carburizer thiab oxidizing cov ntaub ntawv (xws li hlau oxide, alumina, thiab lwm yam) ntxiv rau tib lub sijhawm, nws yooj yim ua rau oxidation ntawm carbon thiab txo qhov nqus ntawm cov pa.
5. Rauv hom thiab kev ua haujlwm(Dab tsi yog qhov cuam tshuam rau qhov nqus ntawm carburizer?)
- Rauv hom:Qhov sib txawv smelting furnaces (xws li hluav taws xob arc rauv, induction furnaces, blast furnaces, thiab lwm yam) muaj qhov sib txawv ntawm qhov nqus ntawm carburizer. Piv txwv li, nyob rau hauv induction furnaces, qhov nqus ntawm cov carburizer feem ntau yog siab dua vim qhov zoo fluidity nyob rau hauv lub molten pas dej ua ke.
- Atmosphere tswj:Nyob rau hauv cov txheej txheem smelting, tswj qhov txo qhov cua pab txo cov oxidation ntawm carburizer thiab txhim kho tus nqi nqus.
6. Lwm yam sab nraud(Dab tsi yog qhov cuam tshuam rau qhov nqus ntawm carburizer?)
- Cia tej yam kev mob ntawm lub carburizer:Yog hais tias lub carburizer ntub dej los yog oxidized, nws qhov kev ua tau zoo yuav txo qis, yog li txo qhov nqus tau.
- Kev paub ntawm tus neeg ua haujlwm:Cov kws tshaj lij tuaj yeem tswj hwm kev noj zaub mov zoo dua, qhov kub thiab txias thiab kev siv zog kom ua kom zoo dua qhov nqus ntawm carburizer.
