1. Kev lag luam hlau yog dab tsi?kev nqus tsev tas mus li?

Kev siv lub tshuab nqus tsev txuas ntxiv mus rau hauv cov hlau yog ib hom kev siv tshuab tshiab uas yaj cov hlau hauv qab lub tshuab nqus tsev thiab txhaj rau hauv pwm kom tsim cov khoom siv hlau los ntawm kev txias thiab khov ntawm pwm. Kev siv lub tshuab nqus tsev txuas ntxiv mus rau hauv lub tshuab nqus tsev muaj qhov zoo dua li cov txheej txheem ib txwm muaj xws li kev ua haujlwm zoo, kev raug siab, thiab kev siv hluav taws xob tsawg.

2. Cov khoom siv feem ntau siv rau hauv kev nqus tsev casting

Cov khoom siv feem ntau siv rau kev nqus tsev feem ntau suav nrog cov cub tawg nqus tsev, cov tshuab nqus tsev, cov pwm casting, thiab lwm yam. Ntawm lawv, lub cub tawg nqus tsev yog cov khoom siv tseem ceeb uas tsim nyog rau kev npaj cov castings zoo, uas tuaj yeem muab qhov chaw nqus tsev ruaj khov kom ntseeg tau tias qhov zoo thiab kev ua tau zoo ntawm cov castings.

3. Txheej txheem thiab txheej txheem

Cov thev naus laus zis thiab cov txheej txheem ntawm kev ua kom lub tshuab nqus tsev tas mus li yog qhov nyuaj heev, xav tau ntau kauj ruam xws li kev ua kom sov ua ntej, kev kho lub tshuab nqus tsev, yaj, nchuav, khov, thiab lwm yam. Ntawm lawv, kev kho lub tshuab nqus tsev yog cov txheej txheem tseem ceeb ntawm kev ua kom lub tshuab nqus tsev tas mus li hauv cov hlau, uas tuaj yeem tshem tawm cov pa roj thiab cov khoom tsis huv hauv cov hlau, kom ntseeg tau tias qhov zoo thiab qhov du ntawm qhov casting.

4. Cov kev daws teeb meem rau cov teeb meem uas feem ntau tshwm sim

Hauv cov txheej txheem ntawm kev nqus tsev tas mus li hauv metallurgy, cov teeb meem feem ntau suav nrog kev kub dhau ntawm lub crystallizer, hlau splashing, roj tso tawm tsis zoo, thiab porosity. Cov txheej txheem los daws cov teeb meem no suav nrog kev ua kom zoo dua ntawm tus qauv ntawm lub crystallizer, kho qhov system cua sov, thiab txhim kho cov txheej txheem nchuav.

5. Kev Txheeb Xyuas

Kev siv cov txheej txheem nqus tsev hlau tsis tu ncua tsis yog tsuas yog txhim kho qhov zoo thiab kev ua tau zoo ntawm kev castings, tab sis kuj txhim kho kev tsim khoom thiab txuag hluav taws xob. Nrog rau kev txhim kho tas mus li ntawm kev lag luam tsim khoom, kev nqus tsev hlau tsis tu ncua yuav siv dav thiab dhau los ua cov thev naus laus zis tseem ceeb hauv kev lag luam casting yav tom ntej.

Cov txiaj ntsig thiab qhov tsis zoo ntawm kev siv lub tshuab nqus tsev vacuum casting yog dab tsi?

Kev casting hauv lub tshuab nqus tsev yog ib txoj kev casting hauv ib puag ncig nqus tsev, uas muaj qee qhov zoo thiab qhov tsis zoo piv rau cov txheej txheem casting ib txwm muaj. Nov yog qee qhov zoo thiab qhov tsis zoo ntawm kev casting hauv lub tshuab nqus tsev:

Cov txiaj ntsig:

Cov khoom zoo: Qhov chaw nqus tsev tuaj yeem txo qhov kev sib cuag ntawm cov hlau thiab cov pa roj xws li oxygen thiab nitrogen hauv huab cua, yog li txo cov oxidation thiab lwm yam kev ua qias tuaj, uas pab tsim cov khoom hlau thiab cov khoom sib xyaw zoo thiab huv si.

Kev tswj qhov tseeb: Thaum lub sijhawm ua cov txheej txheem nqus tsev, cov yam xws li kub, siab, thiab huab cua tuaj yeem tswj tau meej dua, ua rau cov khoom sib xyaw thiab cov khoom ntawm cov khoom sib xws thiab sib xws, yog li txhim kho qhov tseeb ntawm cov khoom.

Txo cov porosity thiab cov inclusions: Vim yog cov roj tsawg hauv qhov chaw nqus tsev, nws pab txo cov porosity thiab cov inclusions hauv casting, txhim kho qhov sib xws thiab qhov ceev ntawm cov khoom.

Haum rau cov hlau uas yaj sai heev: Kev siv lub tshuab nqus tsev yog qhov tsim nyog rau kev siv cov hlau thiab cov hlau uas yaj sai heev vim tias nyob rau hauv ib puag ncig uas nqus tsev, qhov yaj sai ntawm cov ntaub ntawv no raug txo qis, uas pab tswj cov txheej txheem casting zoo dua.

Kev tiv thaiv ib puag ncig: Cov txheej txheem nqus tsev ua kom txo tau cov pa roj thiab cov khib nyiab khov, ua rau nws zoo rau ib puag ncig.

Qhov Tsis Zoo:

Tus nqi khoom siv siab: Cov khoom siv nqus tsev feem ntau kim dua vim tias nws xav tau kev tsim tshwj xeeb thiab cov txheej txheem tswj hwm meej heev.

Kev txij nkawm nyuaj: Kev txij nkawm thiab kev ua haujlwm ntawm cov khoom siv nqus tsev yog qhov nyuaj heev, xav tau kev paub thiab kev txawj ntse.

Kev ua haujlwm tsis zoo: Piv rau qee txoj kev casting ib txwm muaj, kev nqus tsev casting yuav muaj kev ua haujlwm qis dua, tshwj xeeb tshaj yog rau kev tsim khoom loj.

Daim Ntawv Thov Txwv: Kev siv lub tshuab nqus tsev feem ntau yog siv rau hauv cov teb uas xav tau cov khoom zoo heev thiab cov hlau ntshiab, uas yuav zoo li nyuaj thiab kim heev rau cov ntawv thov dav dav.

Zuag qhia tag nrho, kev siv lub tshuab nqus tsev yog ib qho thev naus laus zis siab heev uas haum rau cov chaw thov tshwj xeeb, thiab kev sib pauv ntawm qhov zoo thiab qhov tsis zoo nyob ntawm cov kev xav tau thiab cov kev cai tshwj xeeb ntawm kev tsim khoom.

Lub tshuab nqus tsev Hasung txuas ntxiv mus yuav ua tau raws li qhov xav tau rau cov hlau zoo hauv ntau yam lag luam.
