Nrog rau qhov nyuaj ntawm kev ua haujlwm hlau thev naus laus zis, cov hlau tshiab rau cov qauv tshwm sim, thiab ntau qhov chaw hauv metallurgical teb tsis cuam tshuam. Txawm li cas los xij, cov ntaub ntawv uas tau sawv ntawm qhov kev sim ntawm lub sijhawm thiab tseem tsis tau muaj txiaj ntsig vim lawv qhov zoo yog tseem siv ntau yam kev lag luam.

Hlau casting tseem yog ib qho ntawm cov lus qhia tseem ceeb hauv kev ua haujlwm ntawm cov tuam txhab metallurgical feem ntau. Yog vim li cas nyob rau hauv lub fact tias cov khoom ua los ntawm cov khoom no yog nyob rau hauv siab thov. Cov khoom zoo li no txawv ntawm lub neej ua haujlwm ntev, nrog rau kev ua haujlwm ntev.

Iron casting technology

Cov txheej txheem tsim khoom tsis tau hloov pauv ntau lub sijhawm. Cam khwb cia hlau casting yog tsim los ntawm cam khwb cia hlau castings raws li tej yam kos duab, nyob rau hauv uas lawv tsis tau teem.

Cov txheej txheem ua tiav yog nyob ntawm cov thev naus laus zis uas siv hauv ib lub lag luam tshwj xeeb. Nyob rau tib lub sijhawm, feem ntau, nws xav tias cov alloy hauv cov kua dej yog pub rau hauv cov ntawv tshwj xeeb. Tom qab cov cam khwb cia hlau tau txias thiab khov kho, nws tuaj yeem txiav thiab tshem tawm ntawm pwm, thiab tom qab ntawd ua haujlwm ntxiv. Hauv kev tsim cov cam khwb cia hlau castings, nws yog assumed tias ntxiv machining ntawm cov khoom yuav ua.

Cov tuam txhab uas tshwj xeeb hauv qee cov txheej txheem casting tsim ntau yam khoom seem rau ntau yam kev lag luam. Cov cheeb tsam ntawm kev siv thiab kev ua haujlwm ntawm cov hlau cam khwb cia yog nyob ntawm qib ntawm cov khoom siv no.

Production

Nyob hauv kev lag luam, uas yog hauv kev tsim cov tshuab thiab cov cuab yeej siv tshuab, cov dej pov tseg thiab cov khoom siv dej, muaj kev thov siab rau cov khoom uas ua los ntawm cov hlau cam, hu ua "grey". Yog vim li cas rau qhov no nyob rau hauv lub fact tias xws li cov khoom yog check thiab hnav-resistant. Cov khoom no tau lees paub los ntawm qhov tseeb tias graphite ntxiv rau cov hlau.

Ntau lub tuam txhab kev lag luam thov rau cov kev pabcuam xws li kev cai casting ntawm cov khoom siv hlau. Txawm hais tias muaj qhov sib txawv ntawm qhov yuav tsum tau ua rau cov txheej txheem thev naus laus zis, uas tau piav qhia los ntawm peculiarities ntawm cov dej num ntawm cov neeg siv khoom, muaj ib qho kev xav tau dav dav. Nws muaj nyob rau hauv qhov tseeb hais tias kev tsim cov cam khwb cia hlau yuav tsum ua raws li cov yam ntxwv ntawm ib feem, uas yog qhia nyob rau hauv cov kos duab thiab cov ntaub ntawv.

Methods

cam khwb cia hlau nyob rau hauv txias-hardening sib tov yog ib qho ntawm cov niaj hnub technologies. Qhov kev daws teeb meem no xav tias cov pwm yog tsim los ntawm cov khoom sib tov uas muaj cov ntaub ntawv xws li resins. Qhov kom zoo dua ntawm cov pwm ua los ntawm xws li kev sib tov yog nce nruj. Qhov no tshem tawm qhov ua tau zoo ntawm cov qauv ntawm cov khoom yuav raug ua txhaum thaum lub sijhawm tsim khoom.

Sand casting kuj nrovdaim ntawv. Cov cuab yeej siv no siv cov xuab zeb uas tau cog lus. Txoj kev no yog tsim rau kev tsim khoom loj ntawm cov khoom loj, xws li turbine hniav lossis qhov loj ntawm lwm cov txheej txheem.

Tam sim no, hlau casting tseem tab tom txhim kho nquag. Cov txheej txheem tsim khoom tshiab tau ua tiav hauv kev siv thev naus laus zis.
