Njira zopewera oxidative decarburization ya zida zoyeserera za ng’anjo yamagetsi
Njira zopewera oxidative decarburization wa ng’anjo yamagetsi yoyesera workpieces
1. Pamwamba zokutira phala
Njira yokutira phala pamwamba pa workpiece ndi otsika mtengo, yosavuta ntchito, ndipo safuna zipangizo zapadera.
Ngakhale njira yogwiritsira ntchito phala ndi yosavuta komanso yosavuta, pali ngozi yosokoneza ndi kupukuta phala panthawi yotentha, zomwe zingayambitsebe makutidwe ndi okosijeni ndi decarburization. Panthawi imodzimodziyo, phala lilipo pamwamba pa workpiece, zomwe zidzakhudza khalidwe lozimitsira, ndipo workpiece yozimitsidwa sizovuta kuyeretsa. Ndipo, ntchito yomwe imakutidwa ndi phala idzatulutsa utsi wambiri ikatenthedwa, zomwe zidzakhudza kugwiritsa ntchito ng’anjo yamagetsi.
2. Kuphimba ufa wa makala
Gwiritsani ntchito ufa wamakala, kapena yonjezerani zitsulo zoyenerera zachitsulo ndi slag (kukula kwa tirigu 1 ~ 4mm) ku ufa wa makala monga chotetezera, kuphimba workpiece ndi kutenthetsa mu ng’anjo, zomwe zingathe kulepheretsa workpiece ku oxidizing decarburization reaction. Njirayi ndi yophweka komanso yosavuta kugwiritsa ntchito, ndipo mtengo wake ndi wotsika, koma nthawi yotentha iyenera kuwonjezereka moyenera.
3. Kupewa ntchito zapadera zoboola pakati
Kwa zida zina zooneka ngati mwapadera, ndizovuta kupewa oxidative decarburization mwa kupaka matope kapena kupaka ufa wamakala. Panthawiyi, ufa wochuluka wa malasha ukhoza kuikidwa mu ng’anjo ndi thireyi, ndiyeno kutentha kwa ng’anjo kumatha kuwonjezeka mpaka kufika pamtunda wapamwamba. Kutentha kuyenera kukhala kwakukulu kuposa 30 ~ 50 ℃, kotero kuti makala amalumikizana ndi mpweya kuti apange mpweya wokwanira wa kaboni, kuti mpweya wa ng’anjoyo ukhale wosalowerera ndale, ndiyeno zida zapadera zimadzaza, zomwe zimatha kuchepetsa kapena kulepheretsa zochitika za oxidative decarburization.
