Lub ntsiab lus ntawm casting: yog ib txoj kev ua kua hlau ua, uas yog, cov hlau yog rhuab rau cov kua kom nws muaj fluidity, thiab ces poured rau hauv pwm nrog ib tug tej yam zoo ntawm cov kab noj hniav, cov kua hlau nyob rau hauv lub gravity teb los yog sab nraud quab yuam teb siab, centrifugal quab yuam, electromagnetic quab yuam, thiab lwm yam nyob rau hauv qhov kev txiav txim ntawm cov kab noj hniav txias thiab solidification rau hauv kab noj hniav zoo li tus casting. Txoj kev tsim khoom no hu ua casting.
Tam sim no, feem ntau siv hauv casting ntau lawm yog cov ntaub ntawv hlau, vim tias cov kua hlau yog yooj yim ntws, yog li txoj kev casting yog tsim rau ntau yam ntaub ntawv hlau, xws li cam khwb cia hlau, cam khwb cia hlau, cam khwb cia tooj liab alloy, aluminium alloy, thiab lwm yam. , ua kom castings ntawm ntau qhov ntau thiab tsawg thiab cov duab, thiab tuaj yeem ua rau nws cov duab thiab qhov loj me kom ze li sai tau rau cov khoom, yog li txuag hlau kom txo tau cov nyiaj ua haujlwm thiab txo cov nqi tsim khoom.
Casting txheej txheem ntau lawm
Cov txheej txheem yooj yim tshaj plaws hauv kev tsim cov casting yog xuab zeb casting, cov castings tsim los ntawm cov qauv no rau ntau tshaj 90% ntawm tag nrho qhov hnyav, ntxiv rau cov peev casting, hlau casting, siab casting, centrifugal casting thiab lwm yam casting txoj kev, peb feem ntau. paub qhov txawv ntawm cov xuab zeb casting sab nraum cov qauv qauv hu ua tshwj xeeb casting, vim yog tsim ntawm cov txheej txheem casting sib txawv muaj lawv tus yam ntxwv.
Cov txheej txheem ntawm cov xuab zeb casting yog qhia hauv daim duab 6-1
Casting yam ntxwv
1. muaj zog adaptability. Cov duab ntawm cov casting tuaj yeem ua tau ntau dua, vim tias cov tub ntxhais tuaj yeem siv tau, thiab cov kab noj hniav sab hauv uas nyuaj rau cov txheej txheem los ntawm cov cuab yeej siv kho tshuab dav dav tuaj yeem tau txais. Xws li lub thawv, lub tog raj kheej thaiv, thiab lwm yam.
2.Txoj kev yooj yim loj casting loj, qhov hnyav tsis txwv. Los ntawm ob peb millimeters, ob peb grams mus rau kaum meters mus rau pua pua tons tuaj yeem ua tau. Cov phab ntsa tuab tuaj yeem yog los ntawm 0.5mm txog li 1m cov ntaub ntawv pov thawj tuaj yeem ua cov hlau cam, cam khwb cia hlau, carbon hlau thiab cov hlau tsis muaj hlau.
3.Qhov ntim ntau lawm tsis txwv. Los ntawm ib daim mus rau me me batch mus rau loj ntau lawm.
4. Tus nqi qis. Castings tuaj yeem siv ncaj qha siv cov khoom seem qis thiab cov chips ua cov khoom siv raw, cov cuab yeej siv qis thiab cov nyiaj ua haujlwm me me ntawm cov castings kom txuag tau hlau.
5.Qhov casting muaj cov khoom siv tsis zoo. Vim yog cov pob zeb ntxhib tsim los ntawm cov kua hlau hauv cov txheej txheem condensation, qhov pores, cov kab nrib pleb thiab lwm yam tsis xws luag yog yooj yim tshwm sim, thiab muaj ntau yam tsis xws luag hauv cov txheej txheem casting ntau lawm, yog li cov khoom siv ntawm cov casting tsis zoo li cov forgings. ntawm tib yam khoom.
casting technology txoj kev loj hlob
Tam sim no, txhua lub teb chaws hauv ntiaj teb tab tom tsim cov cuab yeej siv niaj hnub no los ua cov khoom lag luam casting muaj kev ua tau zoo dua, siab dua precision, tsawg dua npoo thiab ntau dua. Yuav kom ua tau raws li cov kev cai no, cov hlau casting tshiab yuav raug tsim, thiab cov txheej txheem smelting tshiab thiab cov cuab yeej tshiab yuav tshwm sim raws li. High-tech castings nrog tus nqi siab dua yuav raug tsim tawm.
Txoj kev loj hlob ntawm kev siv tshuab casting nyob rau lub sijhawm tom ntej no yuav tshwm sim hauv cov hauv qab no
◇ Kev sib tw rau kev tsim khoom hnyav ntawm ultra-nplua thiab ultra-thin-walled castings.
◇ Hlau matrix composite casting tshuab yuav muaj kev txhim kho zoo.
◇ Rau cov kev taw qhia ntawm ntsuab thiab huv si casting technology, kev txhim kho cov txheej txheem zoo + kev tiv thaiv ib puag ncig kev tsim khoom rau cov kev taw qhia ntawm kev ua haujlwm siab, ntau yam, kev siv tsawg, tsis tshua muaj nqi thiab tsis muaj kuab paug.
◇ Thaum cov txheej txheem ntawm kev siv tshuab thiab automation ntawm casting ntau lawm txuas ntxiv txhim kho, nws yuav raug tsim kho kom hloov tau yooj yim los nthuav cov kev hloov pauv ntawm cov khoom sib txawv thiab ntau yam ntau lawm. Daim ntawv thov ntawm cov neeg hlau thiab cov tshuab hluav taws xob hauv kev tsim cov khoom tsim thiab kev tswj xyuas kuj tseem yuav ua kom dav ntxiv.
◇ Nyob rau hauv cov nqe lus ntawm kev tswj kom zoo, kev siv nruj ntawm cov txheej txheem tswj kev siv tshuab yuav muaj kev txhim kho tshiab hauv kev tshawb nrhiav thiab ntsuas kev ntxhov siab ntawm txhua txoj kev. Nyob rau hauv cov xwm txheej ntawm kev nce qib ntawm kev siv tshuab hluav taws xob thiab kev sim ntsuas txhais tau tias, cov neeg ua haujlwm hauv qhov chaw tsim khoom yuav ua qhov kev tshawb fawb ntau ntxiv ntawm txoj kev xav ntawm cov hlau crystallization solidification thiab xuab zeb compaction. Hauv cov ntsiab lus, casting ntau lawm yuav tsum ua tiav cov txiaj ntsig siab, noj tsawg, tsis muaj mob thiab pheej yig nyob rau hauv qhov chaw zoo thiab kho kom zoo. Lub tshuab casting ntxiv dhau los ua cov npoo me me thiab tsis muaj cov npoo moulding tshuab uas tuaj yeem sib tw nrog lwm cov txheej txheem kev kos duab.
