Semi khoom hlau casting yog txheej txheem kev tsim khoom siab heev uas tsim cov khoom hlau hauv lub xeev ib nrab, txuas qhov sib txawv ntawm cov tsoos forging thiab tuag casting. Los ntawm kev siv cov slurry nrog cov khoom siv tshwj xeeb, cov txheej txheem no ua rau cov kws tsim khoom tsim cov khoom ze-net-puab qhov chaw nrog cov khoom siv zoo tshaj plaws, txo qhov porosity, thiab qhov tsawg tsawg shrinkage defects piv rau cov qauv siv.
Semi Solid Metal Casting yog dab tsi?
Semi khoom hlau casting, feem ntau hu ua thixoforming lossis rheocasting, suav nrog kev ua cov hlau alloys thaum lawv yog cov khoom ib nrab thiab ua kua. Tsis zoo li tus qauv tuag casting qhov twg cov hlau molten yog txhaj, los yog forging qhov twg tag nrho cov hlau zoo li tus, txoj kev no ua hauj lwm nyob rau hauv ib tug tshwj xeeb kub ntau yam hu ua. mushy zone.
Hauv lub xeev no, cov hlau ua pov thawj tsis yog-Newtonian ntws tus cwj pwm, txhais tau tias nws cov viscosity txo qis hauv kev ntxhov siab. Cov yam ntxwv tshwj xeeb no tso cai rau cov khoom siv los sau cov pwm kab noj hniav nrog qis qis, txo qis roj nkag. Qhov tshwm sim yog ib qho kev tivthaiv uas sib xyaw ua ke tsim kev yooj yim ntawm casting nrog cov qauv kev ncaj ncees ntawm forged qhov chaw.
Kev lag luam feem ntau lees paub ob txoj hauv kev los ua kom tiav lub xeev ib nrab: rheocasting thiab thixocasting. Thaum ob qho tib si tsom rau tib qhov txiaj ntsig microstructural - lub ntiaj teb es tsis yog dendritic grain qauv - lawv cov khoom pib thiab cov txheej txheem cua sov sib txawv hauv paus.
Kev Tshawb Fawb Tom Qab Mushy Zone
Kev vam meej ntawm semi-tiav hlau casting tso siab rau kev tswj cov khoom seem, feem ntau ntawm 30% thiab 60%. Ntawm qhov piv txwv no, cov khoom siv tau raug tshem tawm hauv cov kua matrix. Thaum shear quab yuam siv thaum txhaj tshuaj, cov khoom no tig thiab xaub dhau ib leeg, tso cai rau cov dej sib tov ntws zoo li cov kua dej tuab.
Thaum lub shear stress raug tshem tawm, viscosity nce sai, tuav cov duab tam sim ntawd thaum sau cov kab noj hniav. Qhov kev hloov pauv sai no txo qis qhov tsim ntawm cov pores shrinkage, ib qho tsis xws luag hauv ib txwm nqus los yog siab-siab tuag casting. Cov kws tsim khoom muaj txiaj ntsig rau qhov kev kwv yees no rau kev siv tsheb tseem ceeb thiab kev siv dav hlau.
Thawj hom ntawm Semi Solid Processing
Kev nkag siab txog qhov sib txawv ntawm hom kev ua haujlwm tseem ceeb yog qhov tseem ceeb rau kev xaiv txoj kev tsim khoom zoo. Qhov kev xaiv feem ntau yog nyob ntawm cov khoom siv raw, qhov nyuaj, thiab qhov xav tau ntau lawm.
Rheocasting: Los ntawm Kua rau Semi-Solid
Rheocasting pib nrog tag nrho molten hlau. Cov kua alloy yog txias nyob rau hauv kev tswj xyuas los tsim ib tug semi-khoom slurry ncaj qha ua ntej txhaj tshuaj. Txoj kev no tshem tawm qhov xav tau tshwj xeeb ua ntej-cam khwb cia billets, muab kev yooj yim dua hauv kev xaiv alloy.
- Txheej Txheem Flow: Melt npaj → Tswj cua txias / slurry creation → Txhaj rau tuag → Solidification.
- Qhov tseem ceeb Advantage: Kev siv hluav taws xob qis dua vim tsis tas yuav remelting ntawm billets.
- Daim ntawv thov haum: Qhov zoo tshaj plaws rau kev tsim khoom loj loj uas ua rau qhov ua tau zoo txuas ntxiv.
Kev nce qib tsis ntev los no hauv rotor-based stirring thiab electromagnetic stirring tau txhim kho qhov sib xws ntawm rheocast slurries. Cov kev tsim kho tshiab no ua kom muaj kev sib faib ntawm cov khoom sib txawv, uas yog qhov tseem ceeb rau kev tswj xyuas cov tshuab isotropy hauv qhov kawg.
Thixocasting: Los ntawm Khoom Billet rau Semi-Solid
Thixocasting pib nrog ib tug tshwj xeeb npaj khoom billet uas muaj ib tug nplua, non-dendritic microstructure. Qhov no billet yog reheated rau lub semi-kub kub ntau yam thiab ces txhaj rau hauv pwm. Cov khoom siv feedstock feem ntau yog tsim los ntawm kev nruam nruam nrog kev ntxhov siab hnyav.
- Txheej Txheem Flow: Billet txiav → Induction reheating → Semi-solid forming → Ejection.
- Qhov tseem ceeb Advantage: Cov khoom siv zoo ib yam zoo vim yog tswj hwm microstructure ntawm cov khoom noj.
- Daim ntawv thov haum: Txaus siab rau cov khoom siv ua haujlwm siab uas yuav tsum tau tswj kev ua siab ntev.
Thaum thixocasting muaj qhov ua tau zoo dua qub, nws yuav tsum muaj cov kauj ruam txuas ntxiv los tsim cov ntawv tshwj xeeb. Qhov no tuaj yeem cuam tshuam cov nqi tsim khoom rau cov khoom me me piv rau qhov ncaj qha yaj mus kom ze ntawm rheocasting.
Kauj ruam-by-Step Guide rau Semi Solid Casting txheej txheem
Kev ua tiav semi-tiav hlau casting kev ua haujlwm yuav tsum muaj kev tswj xyuas meej ntawm thermal thiab mechanical parameters. Cov kauj ruam hauv qab no qhia txog cov txheej txheem ua haujlwm uas siv hauv cov chaw ua haujlwm niaj hnub no.
Kauj Ruam 1: Kev Npaj Alloy thiab Slurry Generation
Cov txheej txheem pib nrog kev xaiv cov hlau uas tsim nyog, feem ntau yog txhuas lossis magnesium series. Rau rheocasting, cov hlau molten yog txias rau lub hom phiaj kub thaum muaj agitated los tiv thaiv dendrite tsim. Hauv thixocasting, pre-cut billets raug tshuaj xyuas rau microstructural kev ncaj ncees ua ntej cua sov.
Kev tswj qhov kub thiab txias yog qhov tseem ceeb ntawm no. Deviations ntawm ob peb degrees tuaj yeem hloov cov khoom seem loj, cuam tshuam rau tus cwj pwm ntws. Sensors saib xyuas cov thermal profile tsis tu ncua kom ntseeg tau tias qhov sib xyaw tseem nyob hauv thaj chaw pom kev zoo.
Kauj Ruam 2: Reheating thiab Hloov (Thixocasting Specific)
Yog tias siv txoj kev thixocasting, cov khoom billets yog rhuab siv induction coils. Txoj kev no muab cov cua sov sai thiab zoo ib yam, nqa cov khoom mus rau lub xeev ib nrab sai kom txo qis oxidation. Tom qab ntawd cov rhuab slug raug xa mus rau qhov txhaj tshuaj chamber ntawm lub tshuab casting.
Automation plays lub luag haujlwm tseem ceeb hauv theem no. Robotic caj npab feem ntau tuav cov kev hloov mus los tswj lub sijhawm voj voog thiab ua kom cov neeg siv kev nyab xeeb. Qhov ceev ntawm kev hloov pauv yuav tsum tau ua kom zoo kom tiv thaiv kom tsis txhob ntxov ntxov ua ntej txhaj tshuaj.
Kauj Ruam 3: Txhaj thiab Kab Tsuag Filling
Lub semi-khoom slurry yog txhaj rau hauv cov hlau tuag ntawm qhov siab tshaj plaws tab sis qis qis dua li cov kua ua kua. Vim lub viscosity siab dua, qhov ntws pem hauv ntej yog laminar, uas ua rau txo qis cua nkag. Lub siab yog khaws cia thoob plaws lub sijhawm ua kom tiav kom tiav cov kab noj hniav.
Laminar ntws yog lub ntsiab txhais ntawm cov kauj ruam no. Tsis zoo li turbulent kua hlau ntws uas ntxiab roj npuas, qhov muab tshuaj txhuam zoo li cov hlau ib nrab thawb cua tawm hauv qhov cua kom zoo. Qhov no ua rau denser qhov chaw nrog tsawg dua voids.
Kauj Ruam 4: Solidification thiab Ejection
Thaum cov kab noj hniav puv lawm, ib feem solidifies sai nyob rau hauv siab. Qhov xwm txheej ib nrab tso cai rau lub sij hawm voj voog sai dua vim tias cov khoom twb tau ua tiav lawm. Tom qab txaus txias, lub ejector pins tso tawm cov khoom ntawm qhov tuag.
Qhov ze-net-shape muaj peev xwm txhais tau tias tsawg kawg tom qab ua tiav yuav tsum tau ua. Ntau qhov chaw tuaj yeem txav ncaj qha mus rau qhov chaw ua haujlwm lossis chaw kho mob saum npoo yam tsis muaj kev txiav lossis degating, ua kom cov kab ntau lawm.
Kauj Ruam 5: Kev soj ntsuam zoo thiab kev kho cua sov

Semi khoom hlau casting sawv cev rau qhov tseem ceeb ntawm kev nce qib hauv kev tsim hlau, muab cov kev daws teeb meem nyuaj rau cov kws ua haujlwm uas xav tau kom sib npaug ntawm cov duab kos duab nrog kev ua haujlwm siab. Los ntawm kev siv cov khoom tshwj xeeb ntawm lub xeev ib nrab, cov tuam txhab tsim khoom tuaj yeem tsim cov khoom lag luam uas ua tau zoo tshaj qhov qub castings hauv lub zog, xau nruj, thiab sib xws.
Cov tshuab no yog qhov zoo tagnrho rau:
- Automotive engineers nrhiav kom txo lub tsheb hnyav thaum tswj kev sib tsoo.
- Aerospace designers xav tau cov khoom muaj kev ntseeg siab nrog cov yam ntxwv sab hauv.
- Cov neeg tsim khoom lag luam nyob rau hauv electronics xav tau kev ruaj khov, nyias-walled enclosures nrog premium finishes.
Rau cov koom haum xav txog qhov kev hloov pauv no, cov kauj ruam tom ntej yuav muaj kev kawm ntxaws txog kev tsim cov khoom siv tam sim no. Kev ntsuam xyuas lub peev xwm rau kev sib sau ua ke thiab kev txo qis ntawm machining tuaj yeem nthuav qhia cov nyiaj txiag tseem ceeb. Kev koom tes nrog cov neeg muaj kev paub dhau los uas tshwj xeeb hauv kev ua haujlwm ib nrab thiab kev ua haujlwm siab yuav ua kom muaj kev ua haujlwm zoo thiab ua kom tau txais txiaj ntsig zoo tshaj plaws ntawm txoj kev tsim khoom zoo tshaj plaws.
