Xuab zeb casting yog txheej txheem casting

Xuab zeb casting yog txheej txheem casting, tseem hu ua xuab zeb casting.Nws yog ib txoj hauv kev ua castings los ntawm kev siv cov xuab zeb hauv cov pwm casting.

Cov txheej txheem xuab zeb casting suav nrog cov kauj ruam hauv qab no:

1. Pwm npaj: Ua ob lub pwm nrog qhov zoo thiab tsis zoo concavities raws li cov duab thiab qhov loj ntawm qhov.Cov pwm zoo yog hu ua cov tub ntxhais, thiab cov pwm tsis zoo yog hu ua sandbox.Cov pwm no feem ntau yog ua los ntawm cov khoom siv refractory.

2. Kev npaj cov xuab zeb: Muab cov tub ntxhais tso rau hauv lub thawv xuab zeb thiab sau nws nrog cov xuab zeb nyob ib ncig ntawm cov tub ntxhais.Foundry xuab zeb feem ntau yog ib qho tshwj xeeb sib xyaw ntawm cov xuab zeb zoo, av nplaum thiab dej.Tom qab ua tiav tiav, cov xuab zeb pwm yog compacted siv lub siab los yog kev co.

3. Melting hlau: Melting cov hlau xav tau rau hauv lub xeev ua kua, feem ntau yog siv lub cub tawg kom sov cov khoom siv hlau.Thaum cov hlau mus txog qhov tsim nyog melting point, cov kauj ruam tom ntej tuaj yeem pib.

4. Pouring: Cov kua hlau yog maj mam nchuav rau hauv cov xuab zeb pwm, sau tag nrho cov duab.Cov txheej txheem pouring yuav tsum tau tswj kub thiab ceev kom tsis txhob muaj npuas, shrinkage kab noj hniav los yog lwm yam tsis xws luag.

5. Solidification thiab Cooling: Thaum cov kua hlau nyob rau hauv lub casting tau txias thiab solidified, lub pwm yuav qhib thiab lub solidified casting tshem tawm ntawm cov xuab zeb pwm.

6. Kev tu thiab tom qab ua tiav: Cov khoom tshem tawm tuaj yeem muaj qee cov xuab zeb lossis grit txuas rau saum npoo thiab yuav tsum tau ntxuav thiab txiav.Cov txheej txheem siv tshuab lossis tshuaj siv tau los tshem tawm grit thiab ua qhov tsim nyog trimming thiab kho.

Xuab zeb casting yog ib qho yooj yim thiab kev lag luam casting txoj kev tsim nyog rau kev tsim cov hlau ntawm ntau qhov ntau thiab tsawg thiab cov duab.Nws yog dav siv hauv kev lag luam xws li automotive, machinery, aerospace thiab zog.

Cov txheej txheem xuab zeb tuaj yeem sau tau yooj yim raws li cov kauj ruam hauv qab no: kev npaj pwm, npaj cov xuab zeb, melting hlau, pouring, solidification thiab txias, tu thiab tom qab ua tiav.

Sand casting tuaj yeem muab faib ua hom hauv qab no raws li cov xuab zeb sib txawv:

1. Mixed Sand Casting: Qhov no yog hom xuab zeb ntau tshaj plaws.Hauv kev sib xyaw xuab zeb casting, cov xuab zeb sib xyaw uas muaj cov xuab zeb, binder thiab dej yog siv.Cov xuab zeb pwm no muaj lub zog siab thiab ua haujlwm ntev thiab tsim nyog rau kev tsim cov khoom me me, nruab nrab thiab loj.

2. Binder xuab zeb casting: Hom xuab zeb no siv cov xuab zeb pwm nrog ib qho tshwj xeeb binder.Binders txhim khu lub zog thiab kav ntev ntawm cov xuab zeb pwm thaum tseem txhim kho qhov zoo thiab qhov tseeb ntawm castings.

3. Hard xuab zeb casting: Hard xuab zeb casting siv cov xuab zeb nyuaj pwm nrog hluav taws kub tsis kam thiab kav ntev.Cov xuab zeb pwm no yog tsim los tsim cov khoom loj thiab cov khoom hnyav, xws li cov cav cav thiab cov hauv paus.

4. Xuab zeb casting los ntawm txoj kev demoulding: Hauv hom xuab zeb casting no, ntau txoj kev demoulding yog siv los ua kev npaj thiab pwm noj cov xuab zeb pwm yooj yim dua.Cov txheej txheem tso tawm muaj xws li ntsuab xuab zeb casting, xuab zeb qhuav thiab tso tawm tus neeg sawv cev xuab zeb casting.

5. Tsiv qauv xuab zeb casting: Tsiv qauv xuab zeb casting yog txoj kev xuab zeb casting uas siv cov pwm txav.Txoj kev no yog tsim rau kev tsim cov castings nrog cov duab complex thiab cov kab noj hniav sab hauv, xws li cov iav thiab turbines.

Cov saum toj no yog cov txheej txheem dav dav thiab kev faib tawm ntawm cov xuab zeb casting.Cov txheej txheem tshwj xeeb thiab kev faib tawm tuaj yeem hloov pauv raws li kev xav tau thiab cov khoom siv sib txawv.
