Decarburization yog ib qho tshwm sim thiab muaj teeb meem tshwm sim thaum lub sij hawm kho cua sov ntawm cov hlau thiab lwm yam hlau alloys. Nws hais txog qhov poob ntawm cov pa roj carbon monoxide los ntawm cov txheej txheej saum npoo ntawm cov khoom thaum raug kub kub hauv ib puag ncig uas txhawb oxidation. Cov pa roj carbon monoxide yog ib qho tseem ceeb hauv cov hlau, ua rau nws lub zog, hardness, thiab hnav tsis kam. Yog li ntawd, decarburization tuaj yeem ua rau txo cov khoom siv dag zog, degradation degradation, thiab tag nrho cov khoom zoo. Yuav kom daws tau qhov teeb meem decarburization hauv kev kho cua sov, ntau txoj hauv kev thiab cov tswv yim tiv thaiv tuaj yeem ua haujlwm.
1. Tswj huab cua
Ib txoj hauv kev zoo tshaj plaws los txo cov decarburization yog los ntawm kev tswj cov cua sov cua thaum lub sij hawm kho cua sov. Decarburization tshwm sim thaum carbon nyob rau hauv cov hlau reacts nrog oxygen los yog lwm yam gases xws li carbon dioxide, tsim carbon monoxide los yog carbon dioxide uas khiav tawm ntawm qhov chaw. Txhawm rau tiv thaiv qhov no, yuav tsum siv qhov chaw inert lossis txo qis. Cov pa roj carbon monoxide muaj xws li nitrogen, argon, lossis hydrogen, uas tsim kom muaj ib puag ncig tsis muaj oxygen, txo qhov kev pheej hmoo ntawm cov pa roj carbon monoxide.
Qee cov txheej txheem kho cua sov siv lub tshuab nqus tsev vacuum kom tshem tawm tag nrho cov gases uas tuaj yeem cuam tshuam nrog steel nto. Txoj kev no yog qhov tshwj xeeb tshaj yog rau cov khoom muaj txiaj ntsig zoo uas txawm tias qhov tsawg kawg nkaus decarburization tsis tuaj yeem lees txais. Xwb, carburizing atmospheres, qhov twg carbon-nplua nuj gases siv, tuaj yeem pab tswj lossis txawm tias nce qib carbon saum npoo, tiv thaiv qhov muaj peev xwm decarburization.
2. Kev siv cov tshuaj tiv thaiv
Kev siv cov tshuaj tiv thaiv yog lwm txoj hauv kev los tiv thaiv cov khoom ntawm decarburization. Cov txheej txheem xws li ceramic pastes, tooj liab plating, lossis cov xim tshwj xeeb tuaj yeem ua rau lub cev tsis muaj zog, tiv thaiv cov pa roj carbon monoxide tawm ntawm qhov chaw. Cov coatings no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau qhov chaw uas dhau mus ntev kev kho cua sov los yog rau cov khoom raug oxidative heev.
3. Kev kho cua sov tsis zoo
Decarburization yog qhov kub thiab txias, txhais tau hais tias qhov kub thiab txias, qhov ntau dua cov pa roj carbon monoxide yuav khiav tawm ntawm cov hlau. Los ntawm kev ua tib zoo xaiv cov kev kho cua sov thiab lub sijhawm, qhov kev pheej hmoo ntawm decarburization tuaj yeem txo qis. Txo cov txheej txheem kub los yog txo lub sij hawm raug rau ntawm qhov kub thiab txias tuaj yeem txo qis cov pa roj carbon ntau. Qee qhov xwm txheej, kev ua kom txias tsis sib xws thaum lub sij hawm mus ntev kuj tuaj yeem muaj txiaj ntsig zoo, vim nws txo lub sij hawm tag nrho cov khoom raug cuam tshuam rau decarburizing tej yam kev mob.
4. Cov txheej txheem tom qab kev kho mob
Yog tias decarburization tshwm sim txawm tias muaj kev tiv thaiv kev tiv thaiv, cov txheej txheem tom qab kev kho mob xws li kev sib tsoo los yog kev siv tshuab tuaj yeem ua haujlwm kom tshem tawm cov txheej txheem decarburized. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas ntog zoo li hardness thiab hnav tsis kam yog qhov tseem ceeb. Qee qhov xwm txheej, cov txheej txheem carburizing thib ob tuaj yeem siv los kho cov pa roj carbon monoxide uas ploj lawm hauv txheej txheej saum npoo, yog li rov ua kom cov khoom xav tau.
Decarburization hauv kev kho cua sov yog qhov teeb meem tseem ceeb uas tuaj yeem cuam tshuam qhov kev ua tau zoo thiab cov khoom siv hlau zoo. Los ntawm kev tswj cov cua sov cua sov, siv cov txheej txheem tiv thaiv, optimizing cov txheej txheem tsis zoo, thiab siv cov txheej txheem kho tom qab kho, cov kev tsis zoo ntawm decarburization tuaj yeem txo qis. Cov tswv yim no xyuas kom meej tias cov khoom kho tau khaws lawv lub zog, hardness, thiab durability, thaum kawg txhim kho tag nrho cov khoom zoo kawg nkaus.
