Dab tsi yog Stainless Hlau Precision Casting?
Oct 11, 2023| Cov tuam txhab sib txawv muaj cov kev tsim khoom sib txawv (nrog rau cov khoom siv, qhov chaw, cov neeg ua haujlwm zoo, thiab lwm yam), cov cwj pwm tsim khoom thiab kev paub dhau los. Lawv yuav tsum xav txog cov khoom twg tsim nyog thiab qhov twg tsis yog (lossis tsis yog) raws li cov qauv no. Cov kev xav tau thiab cov nqi raug qhov tseeb ntawm cov castings tau los ntawm ntau txoj kev casting yog qhov sib txawv, qhov pib peev thiab cov ntim ntau lawm kuj tsis sib xws, thiab cov txiaj ntsig kev lag luam kuj txawv. Yog li ntawd, kom ua tiav ntau dua, sai dua, zoo dua thiab kev lag luam ntau dua, peb yuav tsum coj mus rau hauv tus account txhua yam.
Stainless hlau casting yog ib lo lus dav dav rau hlau-raws li alloys siv los tsim precision castings yam tsis tau hloov eutectic thaum lub sij hawm condensation txheej txheem. Ib hom cam khwb cia hlau. Cam khwb cia hlau muab faib ua peb pawg: cam khwb cia carbon steel, cam khwb cia hlau tsis tshua muaj hlau thiab cam khwb cia tshwj xeeb hlau.
Muab faib:
(1) Carbon hlau casting. Stainless hlau casting yog ib tug cam khwb cia hlau nrog carbon raws li thawj alloying caij thiab ib tug me me ntawm lwm yam ntsiab. Cov ntsiab lus carbon tsawg dua 0.2% rau cam khwb cia qis-carbon steel, cov ntsiab lus carbon yog 0.2%-0.5% rau cam khwb cia nruab nrab carbon steel, thiab cov pa roj carbon cov ntsiab lus yog ntau dua 0.5% rau cam khwb cia high-carbon steel. Nrog rau qhov sib ntxiv ntawm cov ntsiab lus carbon, lub zog ntawm cam khwb cia carbon steel nce, thiab hardness txhim kho. Lub tshuab kas fes qhov chaw cam khwb cia carbon steel muaj lub zog siab, plasticity thiab tsis kam, tus nqi qis, hauv cov tshuab hnyav siv los ua cov khoom uas lees txais cov khoom loj, xws li dov zeb ncej, hydraulic xovxwm puag, thiab lwm yam .; Nws yog siv rau hauv tsheb ciav hlau los ua qhov chaw uas muaj kev ntxhov siab thiab raug cuam tshuam, xws li hauv ncoo, sab ncej, lub log thiab cov khoom sib txuas.
(2) Stainless hlau precision casting. Cam khwb cia hlau uas muaj alloying ntsiab xws li manganese, chromium, thiab tooj liab. Tag nrho cov ntsiab lus ntawm alloying feem ntau tsawg dua 5%, uas muaj kev cuam tshuam ntau dua thiab tuaj yeem kho cua sov kom tau txais cov khoom zoo dua qub. Casting low-alloy steel muaj kev ua tau zoo dua li cov pa roj carbon steel, uas tuaj yeem txo qhov zoo ntawm qhov chaw thiab txhim kho lub neej kev pab cuam.
(3) Casting tshwj xeeb hlau. Robot stainless hlau fittings yog alloy cam khwb cia hlau rau tshwj xeeb xav tau kev pab, muaj ntau yam, feem ntau muaj ib los yog ntau tshaj high-volume alloying ntsiab kom tau ib tug tej yam kev kawm tshwj xeeb. Piv txwv li, high-manganese hlau uas muaj 11% -14% manganese tuaj yeem tiv taus qhov cuam tshuam, thiab feem ntau yog siv rau cov khoom hnav-tiv taus ntawm cov tshuab mining, neeg hlau stainless hlau fittings, thiab kev tsim kho tshuab; Ntau yam ntawm stainless hlau nrog chromium los yog chromium-nickel ua lub ntsiab alloying, siv rau qhov chaw uas ua hauj lwm nyob rau hauv corrosive los yog siab kub tej yam kev mob siab tshaj 650 degree, xws li lub cev valve, twj tso kua mis, ntim los yog chav turbine vaj tse rau high-muaj peev xwm fais fab chaw nres tsheb. . Lub precision casting specification yog siab, qhov dav dav dav siab ntev yog 1%, qhov pom kev siab siab yog ± 1/2 degrees, thiab qhov chaw tiav tuaj yeem ncav cuag Ra1.
