Hauv cov txheej txheem zom zaws, vim kev sib faib tsis zoo lossis kev them nyiaj, kev txiav txim siab ntau dhau thiab lwm qhov laj thawj, qee zaum cov pa roj carbon nyob rau hauv cov hlau tsis tuaj yeem ua kom tau raws li cov kev xav ntawm lub sijhawm saum toj kawg nkaus, yog li nws tsim nyog ntxiv cov pa roj carbon hlau rau molten hlau. Muaj ntau cov ntaub ntawv uas tuaj yeem siv los ua cov carburizers rau cam khwb cia hlau, xws li cov graphite cuav, calcined roj av coke, graphite ntuj, coke, anthracite thiab cov khoom sib xyaw ua los ntawm cov khoom siv no.
Kev saib xyuas yuav tsum tau them rau cov ntsiab lus hauv qab no hauv kev siv tus neeg sawv cev carburizing rau kev pov, txwv tsis pub nws cov absorptivity yuav cuam tshuam.
1. Cuam cuam tshuam ntawm cov particle loj ntawm carburizer: cov txheej txheem ntawm carburizer suav nrog kev sib cais diffusion txheej txheem thiab oxidation poob txheej txheem. Txoj kev sib cais siab diffusion thiab oxidation poob tus nqi ntawm cov khoom seem sib txawv ntawm cov carburizers sib txawv.
2. Cuam tshuam ntawm tus neeg sawv cev carburizing rau casting: hauv qee qhov ntsuas kub thiab ib yam tshuaj lom neeg sib xyaw, cov saturated concentration ntawm carbon hauv molten hlau yog qee yam. Ntawm qhov kev zaum tshwj xeeb, ntau cov carburizer ntxiv, qhov ntev dua qhov kev sib cais lub sij hawm ntev dua, qhov poob ntau dua qhov sib piv yog, thiab qhov qis dua ntawm qhov nqus tau yog.
3. cuam tshuam ntawm qhov ntsuas kub ntawm qhov tsis txaus ntseeg ntawm carburizing tus neeg sawv cev rau casting: thaum qhov sib npaug siab kub siab dua, qhov nqus ntawm carburizing tus neeg sawv cev txo qis; thaum lub carburizing qhov kub thiab txias qis dua qhov sib npaug ntawm qhov kub thiab txias, lub saturated solubility ntawm carbon txo, qhov kev tsis txaus siab thiab siab tshaj ntawm cov pa roj carbon tsawg, yog li cov txiaj ntsig kuj tsawg. Thaum lub carburizing kub yog nyob rau qhov sib npaug ntawm qhov kub thiab txias, qhov nqus ntawm carburizing tus neeg sawv cev yog qhov siab tshaj plaws.
4. Cov nyhuv ntawm cov nplawm kub hlau ntawm qhov nqus tus nqi ntawm carburizer: lub sijhawm tsim nyog nplawm ntawm kub hlau yuav tsum xyuas kom meej tag nrho kev cuam tshuam ntawm carburizer.
Cov xwm txheej yog qhov tseem ceeb tshaj plaws cuam tshuam rau kev siv cov nyhuv thiab nqus dej ntawm carburetor
