poob ciab casting tau hloov zuj zus mus ua ib txoj kev nrov

Keeb kwm siv nyob rau hauv cov hniav nyiaj hniav kub,ploj wax casting tau hloov zuj zus los ua ib txoj hauv kev nrov ntawm kev tsim cov hlau precision.Piv nrog rau lwm txoj kev tsim khoom, nws nrawm dua, yuav tsum muaj cov neeg ua haujlwm tsawg dua, siv cov cuab yeej siv qis dua, thiab tso cai rau kev tsim kom zoo nkauj.Cov txheej txheem tseem yuav pab txo qis cov khoom pov tseg uas nkag mus rau hauv qhov chaw pov tseg.Muaj ntau yam kev siv ntawm cov txheej txheem, xws li hauv kev lag luam tsheb, kev lag luam aviation, thiab kev lag luam tshuaj.Hauv kev lag luam roj, piv txwv li, cov khoom yuav tsum muaj corrosion-resistantthiab muaj peev xwm tiv taus qhov kub thiab txias.Hauv kev lag luam chemical, lawv yuav tsum tiv taus xeb, yaig, thiab kev kub ntxhov.Ntxiv nrog rau qhov yuav tsum tau muaj cov yam ntxwv tshwj xeeb, cov khoom yuav tsum tau tsim nrog qhov tseeb tshwj xeeb.Kev nqis peev casting yog kev daws teeb meem zoo rau cov teeb meem no.Nws ua rau cov neeg tsim qauv tsim cov ntsiab lus tsis sib xws hauv qhov me me, thaum zam kev xav tau tom qab ua tiav.Cov khoom tiav yog npaj xa tuaj.Nyob rau hauv lub ploj wax casting txheej txheem,ib tug wax qauv yog dipped rau hauv ib tug ceramic slurry.Ceramic slurry coats cov qauv siv quav ciab los ua ib lub plhaub sab nrauv nyuaj.Tom qab ntawd, ib lub molten hlau yog ntxiv rau hardened ceramic plhaub.Cov txheej txheej sab nrauv yog ces raug cua.Kev tshuaj xyuas cov khoom kawg yog ua tiav.Ib qho kev kho saum npoo kuj yog siv.Qhov no tuaj yeem txhim kho cov tsos ntawm cov hlau nto.Qhov ntxov tshaj plaws poob wax casting piv txwv hnub rov qab mus rau 3700 BC.Qee qhov piv txwv ntawm cov khoom siv pov tseg ploj tau pom hauv Ixayees, Nyab Laj, Africa, thiab Indus Valley.Lwm tus tau pom nyob hauv Europe, East Asia, thiab Nigeria.Cov txheej txheem tau siv los ua cov khoom kos duab, duab puab, thiab cov hniav nyiaj hniav kub rau ntau txhiab xyoo.Nyob rau hauv lub xyoo pua 18th, cov txheej txheem tau hloov los ntawm daim-moulding.Txawm li cas los xij, poob ciab casting tseem siv dav hauv kev lag luam hniav nyiaj hniav kub.Nws txoj kev yooj yim ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev cai cov hniav nyiaj hniav kub.Cov txheej txheem wax ploj ploj siv ntau yam hlau,xws li bronze, aluminium, thiab stainless hlau.Cov hlau rau casting yog aluminium vim nws yog machinable thiab corrosion-resistant.Nws kuj muab zoo heev hlau-rau-hlau lubrication.Lwm cov hlau, xws li tooj liab, tuaj yeem siv rau cov txheej txheem casting.Cov txheej txheem yog siv los nrum ntau qhov chaw, los ntawm me me,cov khoom me me mus rau qhov loj, hnyav.Nws yog qhov tshwj xeeb tshaj yog zoo rau cov hlau uas tsis tshua muaj melting point.Nws tseem paub tias muaj txiaj ntsig zoo hauv kev lag luam zaub mov thiab dej haus, qhov twg cov khoom tsim los tiv thaiv cov tshuaj acidic los ntawm cov khoom noj.Hauv kev lag luam tsheb, cov khoom yog tsim los ntawm ob qho tib si ferrous thiab non-ferrous hlau.Cov khoom yog tsim los kom muaj kev nyab xeeb thiab ua haujlwm zoo.Lub hoisting kev lag luam qhov chaw yog siv vertically thiab horizontally, thiab yuav tsum muaj zog.Lawv kuj raug huab cua hnyav thiab kub siab.Kev lag luam tshuaj muaj ntau yam teeb meem corrosion thiab yaig, yog li cov khoom yuav tsum tau tiv taus cov ntsiab lus.Kev lag luam automotive siv poob ciab casting rau nws cov cav tov, gearbox Cheebtsam, thiab compressor qhov chaw.
