Hauv kev lag luam niaj hnub no uas nrhiav kev ua tau zoo tshaj plaws, qhov kev ua tau zoo ntawm cov khoom siv hlau txuas ntxiv mus txiav txim siab qhov siab ntawm cov khoom kawg. Cov txheej txheem casting txuas ntxiv mus ib txwm muaj nyob rau hauv ib puag ncig huab cua, thiab cov teeb meem xws li cov khoom hlau tsis tiav thiab tsis tu ncua yog qhov nyuaj rau zam, uas tau dhau los ua qhov tsis zoo uas txwv tsis pub txoj kev loj hlob ntawm cov khoom siv hlau zoo.

Yog li, puas muaj ib txoj kev siv tshuab uas tuaj yeem tshem tawm cov teeb meem no xws li kev pov hlau hauv 'chaw ib puag ncig'? Cov lus teb yog yog - lub tshuab nqus tsev txuas ntxiv mus. Thiab daim ntawv thov ntawm lub tshuab nqus tsev txuas ntxiv mus yog dav heev

Yog dab tsinqus tsev tas mus li casting?

Hais yooj yim xwb, kev siv lub tshuab nqus tsev tas mus li yog ib txoj kev ua haujlwm siab heev uas txuas ntxiv txhaj cov hlau uas yaj rau hauv lub tshuab crystallizer thiab rub cov hlau casting tawm tas mus li hauv ib puag ncig uas muaj lub tshuab nqus tsev heev. Nws muab ob qho txiaj ntsig tseem ceeb ntawm "kev siv lub tshuab nqus tsev degassing" thiab "kev siv lub tshuab molding tas mus li" ua ke rau hauv ib qho:

Ib puag ncig nqus tsev: tshem tawm tag nrho cov tshuaj tiv thaiv ntawm cov hlau molten thiab cov pa roj xws li oxygen, nitrogen, thiab hydrogen, txo cov porosity thiab oxide inclusions, thiab txhim kho qhov purity, density, thiab cov khoom siv kho tshuab ntawm cov hlau.

Kev tsim tas mus li: Nws ua tiav cov khoom tsim tsis tu ncua los ntawm cov hlau ua kua mus rau cov khoom castings, nrog kev ua haujlwm siab thiab automation, thiab tseem tuaj yeem tau txais cov castings ntev tsis kawg nrog cov qauv sib xws thiab qhov zoo ntawm qhov chaw.

Kev cuam tshuam rau cov lag luam twg? Daim Ntawv Thov Dav Dav ntawm Lub Tshuab Nqus Tsev Nruam Casting

Daim ntawv thov ntawm qhov 'khoom cuav' no mus deb tshaj qhov kev ua haujlwm hlau ib txwm muaj, nws tab tom txhaj tshuaj tshiab rau hauv ntau yam kev lag luam tsim khoom siab.

Cov ntaub ntawv no yog lub hauv paus rau kev tsim cov semiconductor silicon single crystal growth furnace crucibles, lead frames, thiab sputtering targets.
Tus nqi: Cov pa oxygen tsawg heev thiab kev coj ua siab ua kom muaj kev ruaj khov ntawm lub tshav kub thiab kev ua haujlwm ntawm kev xa hluav taws xob tam sim no thaum lub sijhawm tsim cov chip, cuam tshuam ncaj qha rau kev ua tau zoo thiab cov txiaj ntsig ntawm cov chip.

4. Kev tshawb nrhiav thiab kev tsim cov ntaub ntawv tshiab
Daim Ntawv Thov: Cov koom haum tshawb fawb loj thiab cov chaw kuaj khoom siv siv cov tshuab nqus tsev me me los tsim cov qauv tshiab, kawm txog cov txheej txheem khov, thiab ua cov khoom sim me me.
Tus Nqi: Muab ib txoj kev npaj tseem ceeb "thawj kauj ruam" rau cov ntaub ntawv tshiab los ntawm chav kuaj mus rau kev lag luam, ua kom cov ntaub ntawv tshiab tshwm sim sai dua.

Puas yog txhua yam raug pov tseg? Cov qauv twg tuaj yeem ua taulub tshuab nqus tsev tas mus li casting tshuab ua?

Tus "qauv" ntawm lub tshuab nqus tsev txuas ntxiv tsis yog hais txog cov khoom ua si lossis cov duab puab, tab sis yog rau cov khoom tseem ceeb uas nws tsim tawm ncaj qha, uas yog, lub billet rau kev ua tiav tob tom ntej. Raws li cov duab thiab txoj kev kos duab ntawm lub crystallizer, nws tuaj yeem tsim ntau yam "qauv":

1. Qws/Puag ncig Ingot
Kev piav qhia: Qhov no yog daim ntawv feem ntau, nrog rau qhov sib tshuam ncig.
Kev ua tom qab: Nws tuaj yeem ua tiav ntxiv rau hauv cov khoom seem, turbine discs, cov khoom bar, thiab lwm yam los ntawm kev forging, dov, tig, thiab lwm txoj kev.
