Hlau castings yog cov khoom tseem ceeb hauv kev tsim khoom niaj hnub no, thiab cov txheej txheem tsim khoom muaj kev cuam tshuam ncaj qha rau qhov raug, sab hauv kev ncaj ncees, txhua yam khoom, thiab kev pabcuam lub neej. Raws li kev lag luam xws li kev tsim tsheb, tshuab, lub zog, thiab cov cuab yeej siv tsim kho xav tau ntau dua - cov khoom ua haujlwm, cov txheej txheem kev ua haujlwm zoo li qub tau nce ntxiv nrog kev tsim cov thev naus laus zis, tsim cov kev daws teeb meem ntau dua thiab ua tau zoo.
Kev tsim cov hlau casting feem ntau suav nrog kev tsim pwm, hlau melting, pouring, txias thiab solidification, pwm tshem tawm, tu, thiab tom qab ua tiav. Ua ntej pib tsim khoom, engineers tsim pwm thiab txheej txheem tsim raws li cov khoom siv geometry, cov yam ntxwv ntawm cov khoom siv, thiab kev ua haujlwm. Cov hlau xaiv yog ces melted mus rau qhov yuav tsum tau kub thiab poured rau hauv lub pwm kab noj hniav, qhov twg nws maj mam txias thiab solidifies rau hauv cov duab uas xav tau.
Xuab zeb casting yog ib qho ntawm feem ntau siv casting txoj kev vim nws versatility thiab ntau yam kev siv. Nws tuaj yeem ua rau cov khoom sib txawv ntawm qhov ntau thiab tsawg thiab geometries thiab haum rau qhov loj, cov duab nyuaj, thiab qis - mus rau nruab nrab - ntim ntau lawm. Rau cov khoom uas xav tau kev sib txawv geometries thiab kev tswj qhov nruj dua, peev casting tuaj yeem muab kev txhim kho saum npoo zoo thiab ntau dua qhov tseeb los ntawm kev siv cov pwm ua tib zoo thiab cov txheej txheem txheej txheem.
Tuag casting feem ntau yog siv rau siab - ntim ntau lawm ntawm cov khoom tsis yog -ferrous, tshwj xeeb tshaj yog cov uas ua los ntawm txhuas thiab zinc alloys. Molten hlau yog txhaj rau hauv pwm nyob rau hauv lub siab, tso cai rau cov tuam txhab tsim cov khoom nyias nyias- cov phab ntsa thiab cov khoom ua haujlwm tau zoo thaum tuav qhov ntev. Centrifugal casting siv lub zog sib hloov los faib cov hlau molten nyob rau hauv pwm thiab feem ntau siv rau cov khoom cylindrical xws li cov kav dej, lub tes tsho, thiab lwm yam rotationally symmetrical Cheebtsam.
Casting tsis xaus thaum cov khoom raug tshem tawm ntawm pwm. Kev ua haujlwm ntxiv tuaj yeem suav nrog kev tu, kev kho cua sov, kev siv tshuab, thiab kev tshuaj xyuas zoo. Kev kho cua sov tuaj yeem txhim kho cov khoom xws li lub zog, hardness, thiab toughness, thaum machining pab ua kom tiav qhov seem thiab sib dhos cov cai ntawm cov khoom tiav. Kev tshuaj xyuas qhov ntev thiab tsis yog -kev kuaj kev puas tsuaj kuj tuaj yeem siv los txheeb xyuas qhov chaw lossis sab hauv thiab xyuas kom meej tias cov casting ua tau raws li cov qauv tsim nyog.
Cov kws tshaj lij kev lag luam nco ntsoov tias niaj hnub casting ntau lawm tsis yog tsom rau kev tsim cov khoom siv tau zoo. Cov neeg tsim khoom tau nce qhov ntsuas qhov tseeb, kev ua tau zoo, tus nqi tsim khoom, thiab kev xav txog ib puag ncig. Kev nce qib hauv kev simulation, kev tsim khoom siv hluav taws xob, kev saib xyuas cov txheej txheem, thiab cov khoom siv thev naus laus zis tau xav tias yuav txhim kho kev tsim khoom thiab cov khoom sib xws, muab cov khoom pov thawj txhim khu kev qha rau ntau yam kev lag luam.
