Kev paub txog cov khoom siv hlau casting.

Castings

Casting yog ib qho yooj yim, pheej yig thiab ntau txoj hauv kev ntawm kev tsim cov txhuas rau hauv ntau cov khoom. Cov khoom xws li kev xa hluav taws xob thiab lub cav tsheb thiab lub hau rau saum Washington Monument tau tsim los ntawm cov txheej txheem txhuas casting. Feem ntau cov castings, tshwj xeeb tshaj yog cov khoom loj txhuas, feem ntau yog ua hauv cov xuab zeb pwm.

Take Away Facts

• Casting yuav tsum muaj ib feem-tshem tawm tsim

Casting pwm yuav tsum tau tsim kom haum rau txhua theem ntawm cov txheej txheem. Rau kev tshem tawm ib feem, me ntsis taper (lub npe hu ua cua ntsawj ntshab) yuav tsum tau siv rau ntawm qhov chaw perpendicular rau txoj kab sib cais kom tus qauv tuaj yeem raug tshem tawm ntawm pwm.

• Casting qhov chaw nrog kab noj hniav

Txhawm rau tsim cov kab noj hniav hauv cov castings (xws li rau lub cav thaiv thiab lub tog raj kheej taub hau siv hauv tsheb), cov ntaub ntawv tsis zoo yog siv los ua cov cores. Casts ntawm qhov xwm no feem ntau yog tsim nyob rau hauv cov xuab zeb pwm. Cov cores tau muab tso rau hauv lub thawv casting tom qab cov qauv raug tshem tawm.

• Casting rau lub teeb yuag thiab lub zog

Aluminium cov khoom ntawm lub teeb yuag thiab lub zog coj cov txiaj ntsig zoo thaum nrum rau hauv qhov chaw. Ib daim ntawv thov ntawm txhuas tuag cam khwb cia yog nyias-walled enclosures nrog tav thiab tus thawj coj ntawm sab hauv kom ua kom muaj zog.

• Casting nyob rau hauv keeb kwm thaum ntxov ntawm txhuas

Thawj cov khoom lag luam aluminium yog castings xws li cov khoom siv kho kom zoo nkauj thiab cookware. Txawm hais tias tsim los ntawm cov txheej txheem centuries-laus, cov khoom no tau suav hais tias yog tshiab thiab tshwj xeeb.

Cov txheej txheem ntawm casting aluminium

Casting yog thawj thiab feem ntau siv txoj hauv kev los ua txhuas rau hauv cov khoom. Kev txhim kho txuj ci tau ua tiav, tab sis lub hauv paus ntsiab lus tseem zoo ib yam: Molten aluminium yog nchuav rau hauv pwm kom duplicate tus qauv xav tau. Peb txoj kev tseem ceeb tshaj plaws yog tuag casting, pwm mus tas li thiab xuab zeb casting.

Tuag casting

Cov txheej txheem tuag casting yuam molten aluminium rau hauv steel tuag (pwm) nyob rau hauv siab. Cov txheej txheem tsim khoom no feem ntau yog siv rau cov khoom ntim siab. Precisely tsim txhuas qhov uas yuav tsum tau ib tug yam tsawg kawg nkaus ntawm machining thiab xov yuav ua tau los ntawm no casting txoj kev.

Permanent pwm casting

Cov pwm tas mus li casting muaj cov pwm thiab cov cores ntawm cov hlau lossis lwm yam hlau. Molten aluminium feem ntau yog nchuav rau hauv pwm, txawm tias qee zaum siv lub tshuab nqus tsev. Cov pwm tas mus li tuaj yeem ua kom muaj zog dua li tuag lossis xuab zeb castings. Semi-permanent pwm casting cov txheej txheem yog siv thaum cov cores mus tas li yuav tsis tuaj yeem tshem tawm ntawm qhov ua tiav.

Casting Applications

Kev siv dav hauv kev lag luam tsheb thiab tsev

Kev lag luam tsheb yog lub lag luam loj tshaj plaws rau txhuas casting. Cov khoom cam khwb cia ua ntau tshaj li ib nrab ntawm cov txhuas siv hauv tsheb. Cast aluminium kis tau tus mob thiab pistons tau nquag siv hauv tsheb thiab tsheb thauj khoom txij li thaum xyoo 1900s. Cov khoom siv me me, cov cuab yeej siv tes, lawnmowers thiab lwm yam tshuab yog tsim los ntawm ntau txhiab qhov sib txawv ntawm cov aluminium casting duab. Cov khoom siv casting feem ntau siv los ntawm cov neeg siv khoom yog cookware, thawj cov khoom txhuas uas tau tsim muaj rau kev siv txhua hnub.
