Sand casting aluminiumyog cov txheej txheem ntau yam, pheej yig, thiab tuaj yeem ua tiav rau casting txhuas qhov chaw ntawm txhua qhov ntau thiab tsawg. Molten aluminium alloy yog poured rau hauv pwm kab noj hniav tsim los ntawm compacting sib tov ntawm xuab zeb, av nplaum, thiab dej nyob ib ncig ntawm ib tug qauv. Thaum ua tiav zoo, xuab zeb casting tso cai rau kev ua tau zoo aluminium castings nrog cov cuab yeej zoo heev.
Vim li cas aluminium zoo rau xuab zeb casting?
Aluminium yog zoo kawg nkaus haum rau xuab zeb casting vim nws zoo heev fluidity thaum molten, tso cai kom tiav molded cov ntsiab lus, thiab nws tsis tshua muaj melting point uas minimizes thermal hnav ntawm cov xuab zeb pwm. Nrog rau qee yam khoom siv thiab cov ntaub ntawv yooj yim, nws tseem tuaj yeem ua kom muaj kev nyab xeeb kawm cov txheej txheem txhuas xuab zeb hauv tsev. Txawm li cas los xij, rau kev lag luam zoo castings, cov kws tshaj lij kev lag luam zoo li Tuam Tshoj Welong muaj kev txawj ntse thiab muaj peev xwm xaxuab zeb casting aluminiumraws li cov neeg siv khoom specifications.
Yuav Ua Li Cas Sand Mould rau Aluminium Casting?
Kev npaj ntawm cov xuab zeb pwm yog qhov tseem ceeb heev kom tau txais kev ua tiav zoo. Nov yog cov kauj ruam tseem ceeb:
1. Tau txais cov xuab zeb zoo silica. Angular nplej nrog uniform loj faib pwm zoo.
2. Ntxiv bentonite av nplaum ntawm 5-15% ntawm cov xuab zeb hnyav. Cov av nplaum ua raws li kev khi.
3. Kev xaiv muaj xws li additives xws li cov hmoov av hmoov av los txhim kho collapsibility.
4. Ua tib zoo sib xyaw cov xuab zeb thiab cov khoom ntxiv thaum qhuav.
5. Maj mam sib tov hauv dej, feem ntau sib npaug li 4% ntawm cov xuab zeb los ntawm qhov hnyav. Cov xuab zeb yuav tsum sib sau ua ke los ntawm kev tsis ntub dej.
6. Knead cov xuab zeb sib tov zoo kom txog thaum pliable thiab zoo ib yam thoob plaws.
7. Ntim cov xuab zeb npaj ib ncig ntawm cov qauv halves, compacting nws zoo rau hauv cov contours.
8. Ua tib zoo cais cov xuab zeb pwm ib nrab ntawm cov qauv.
9. Muab cov pwm ib nrab ua ke ua ke ntawm lub khob ntim thiab qhov cua.
10. Yeem: tua cov pwm sib dhos kom tawv thiab ntxiv dag zog rau nws ua ntej nchuav.
Cov khoom ntawm cov xuab zeb yuav tsum tau tswj kom ua tiav zoo permeability, collapsibility, thiab nto tiav ntawm castings. Kev sim cov qauv castings pab hu rau hauv cov xuab zeb zoo sib xyaw. Cov iav kev nyab xeeb zoo li lub tshuab ua pa thiab cov khaub ncaws tiv thaiv yuav tsum hnav thaum tuav cov xuab zeb silica.
Yuav Ua Li Cas Sand Cast Aluminium Hauv Tsev?
Nrog kev ceev faj txog kev nyab xeeb, txhuas tuaj yeem ua xuab zeb hauv tsev siv cov khoom siv yooj yim:
Cov khoom siv xav tau:
- Zoo xuab zeb
- Bentonite av nplaum
- Hlau lossis ntoo los ua cov qauv
- Da dej, sib tov ntim
- Hlau melting rauv
- Cov khoom siv tiv thaiv
Cov kauj ruam rau Tsev Sand Casting:
1. Tsim ib qho qauv ob-daim rau koj tus qauv tsim. Cov ntaub ntawv zoo sib xws yog ntoo, yas, lossis txhuas.
2. Npaj cov xuab zeb ntsuab sib tov thiab tsim pwm halves nyob ib ncig ntawm tus qauv.
3. Clamp pwm halves ua ke nruj nreem.
4. Melt aluminium scraps los yog ingots nyob rau hauv lub cub tawg mus txog 1300 degree F. Siv qhov cua kom zoo.
5. Ncuav molten aluminium maj mam thiab smoothly rau hauv lub khob pwm.
6. Tso cai rau cov hlau kom ruaj khov ua ntej tawg qhib pwm.
7. Tshem tawm casting los ntawm pwm thiab ntxuav tawm cov xuab zeb ntau dhau.
8. Kev xaiv cov kauj ruam xws li kev kho cua sov lossis machining kom tiav cov casting.
Cov xuab zeb hauv tsev yooj yim tuaj yeem tsim cov khoom zoo nkauj lossis ua haujlwm zoo txhuas. Txawm li cas los xij, rau ntau qhov geometries thiab zoo tsim nyog rau engineering daim ntaub ntawv, kev foundries xws li Tuam Tshoj Welong muaj peev xwm ua tau raws li qhov yuav tsum tau ua. Thov hu rau peb kom nug.
