Dab tsi yog Shrinkage tus nqi ntawm Zinc Tuag Casting?

Qhov kev xav ntawm Zinc Tuag tsuas yog nyob ntawm cov khoom xws li cov khoom siv alloy, Tuag Casting qauv, Phab Ntsa Thicking thiab nchuav kub. Qhov loj me ntawm shrinkage tus nqi tuaj yeem suav los ntawm cov qauv hauv qab no:

Cov xwm txheej cuam tshuam rau shrinkage tus nqi ntawm zinc tuag casting

Cov khoom siv alloy: Cov khoom sib txawv casting muaj qhov sib txawv shrinkage tus nqi. Piv txwv li, cam khwb cia hlau muaj ib tug loj shrinkage tus nqi, thaum grey cam khwb cia hlau muaj ib tug me me shrinkage tus nqi. Silicon tuaj yeem txhawb nqa qhov txo qis, thaum leej faj yuav ua rau kom tus nqi shrinkage.

Cov qauv ntawm kev tuag casting: Cov qauv ntawm kev tuag casting, xws li phab ntsa thickness, tav, thiab lwm yam, yuav cuam tshuam rau qhov txias txias thiab shrinkage.

Pouring kub: Qhov kub ntawm qhov pouring ntau dua, qhov ntau dua cov alloy superheat, thiab cov kua shrinkage ntau dua. Lub pouring ceev thiab qhov rov qab ncuav thaum lub sij hawm pouring txheej txheem kuj yuav cuam tshuam lub shrinkage ntawm lub casting.

Lub cev thiab mechanical zog ntawm zinc alloy
Zinc alloy yog ib qho yooj yim los tuag-cam ntawm qhov chaw qis qis (385 degree), thiab muaj chav nyob zoo chav kub thiab coj kev tiv thaiv zoo. Tsis tas li ntawd, Zinc Alloy tsis nqus hlau, corrode tuag, lossis lo rau pwm thiab tuag casting.
