Aluminium tau pom daim ntawv thov dav hauv ntiaj teb niaj hnub no. Cov hlau no yog tus cwj pwm los ntawm lub teeb yuag, ductility thiab ductility, uas tso cai rau nws siv rau ntau yam lag luam. Nws melting point yog 660 ° C. Hauv kev tsim khoom, aluminium casting feem ntau yog siv, ua tsaug rau txhua yam khoom tsim.

Technological process

Tib neeg tau smelting aluminium tau ntev. Nws yooj yim tau txais ib qhodaim ntawv, yog li nws tsuas yog qhov tseem ceeb hauv kev lag luam thoob ntiaj teb. Niaj hnub no, ntau lub mills steel siv high-pressure casting technology. Nws yog tsim nyob rau hauv ib tug tshwj xeeb chamber siv lub piston, uas yog cuam tshuam los ntawm compressed cua, emulsion los yog roj, accelerating lub zog. Cov hlau molten nkag mus rau hauv lub siab-lub zog steel pwm ntawm qhov ceev ntawm li 50 m / s, uas xyuas kom meej tias nws puv tag.

Tuag casting txhuas muaj ntau yam zoo, suav nrog tsis tsuas yog nce kev tsim khoom, tab sis kuj siab precision ntawm cov khoom tiav. Cov thev naus laus zis yog siv los tsim cov khoom tseem ceeb hauv instrumentation, mechanical engineering thiab aircraft manufacturing.

Aluminium casting tom tsev

Ib feem yooj yim ntawm cov hlau no tuaj yeem ua taunws tus kheej. Txhua yam koj xav tau rau qhov no tuaj yeem nrhiav tau hauv tsev cob qhia.

Ua ntej tshaj plaws, koj yuav xav tau lub thawv nrog lub hau uas lub ntiaj teb molding yuav khaws cia. Aluminium casting feem ntau yog ua los ntawm kev sib xyaw ntawm cov xuab zeb thiab av nplaum. Rau qhov me me, koj tuaj yeem nqa cov silica zoo tib yam. Nws yuav tsum tau sifted thiab ncuav rau hauv ib lub thawv ntoo npaj.

Hauv kev ua haujlwm, yuav xav tau cov cuab yeej hauv qab no: ntoo spatula, tweezers, hooks, scalpels, txhuam, txhuam thiab ib lub trowel ua los ntawm cov hlau zoo thiab muaj qhov du.

Aluminium casting tom tsev cuam tshuam nrog kev nchuav hlau rau hauv pwm. Lawv tuaj yeem ua los ntawm lub thawv ntoo.

ua pwm

Kev tsim ntawm ntu yav tom ntej yuav tshwm sim hauv ob lub khob (thav duab). Txhawm rau ua rau lawv,koj yuav tsum tau tshem tawm hauv qab thiab lub hau ntawm lub thawv thiab txiav nws nrog txoj hlua ntev ntev rau hauv ob feem ntawm qhov siab sib txawv. Nyob rau hauv lub resulting flasks, nws yog ib qhov tsim nyog los laum ob lub qhov ntsug ntawm cov phab ntsa rov qab thiab ntxig coke rods rau hauv lawv. Thaum kaw lub thawv, cov cokes tawm hauv qab ntawm lub thawv yuav tsum mus rau hauv lub qhov drilled nyob rau sab saum toj ncej. Qhov no yuav tso cai rau koj los kho cov khob cawv kom raug rau ib leeg.

Nrog rau qhov raug tsim pwm rau casting txhuas hauv av, ib kab noj hniav yuav tsum tau txais uas yuav luam tag nrho cov cam khwb cia. Nws yog ua los ntawm nias ib sab ntawm daim ntawv theej ntawm cov khoom rau hauv av ntawm lub khob haus dej sab saud, thiab lwm qhov mus rau saum npoo ntawm lub raj mis. Cov ncej yuav tsum pwdaim ntaub thaiv muaj zog. Daim ntawv luam ntawm qhov tuaj yeem ua los ntawm ntoo lossis ua npuas ncauj.

Lub backfilling ntawm lub ntiaj teb molding yuav tsum maj mam. Txhua txheej tshiab yuav tsum tau zoo tamped, txwv tsis pub lub ntiaj teb sifted yuav tsis tuav nws cov duab. Nws tseem yuav ua ob peb qhov hluav taws xob qhov hluav taws xob thiab ntxig ib sprue los ntawm cov hlau molten yuav ntws. Tam sim no koj yuav tsum cia lub ntiaj teb qhuav zoo.

Pov txhuas rau hauv pwm

Ua ntej koj thaum kawg sib sau ua ke, koj yuav tsum ua tib zoo tshuaj xyuas nws thiabkom paub tseeb tias tsis muaj pob hauv ntiaj teb. Aluminium casting yuav muab qhov txiaj ntsig zoo tsuas yog tias qhov chaw so zoo kawg nkaus rov ua cov khoom lag luam. Kev sib koom ua ke ntawm cov dej qab zib thiab sab sauv tau pom zoo kom npog nrog av nplaum kom cov kua hlau tsis dhau dhau ntawm cov npoo ntawm qhov chaw so. Tom qab ntawd, lub khob dej sab saud tau muab tso rau ntawm qhov qis thiab kho nrog cokes.

Aluminium yuav tsum tau yaj hauv lub tin los ntawm muab tso rau hauv qhov cub. Thaum cov hlau tsis ua raws li cov poker txo qis rau hauv nws, nws tuaj yeem raug tshem tawm ntawm qhov hluav taws kub thiab nchuav rau hauv pwm los ntawm cov sprue.

Tom qab tos kom txias, nws yuav tsum tshem cov khoom tawm hauv av. Feem ntau, tom qab qhov no, kev ua haujlwm ntxiv ntawm cov khoom yog nqa tawm, suav nrog kev txiav tawm ntau dhau ntawm cov npoo thiab tig.

Aluminium casting yog txheej txheem zoo siab thiab muaj txiaj ntsig. Ua tsaug rau cov thev naus laus zis no, qhov me me tuaj yeem ua los ntawm koj tus kheej, uas yuav ua rau koj muaj kev zoo siab thiab txuag nyiaj.
