Grey Cam khwb cia hlau Castings

Grey cam khwb cia hlau (tseem hu ua grey cam khwb cia hlau) yog ib pawg ntawm cov cam khwb cia hlau nrog rau ntau hom qib raws li qhov sib txawv ntawm cov qauv sib txawv. Grey cam khwb cia hlau yog ib hom hlau-carbon alloy thiab nws tau txais nws lub npe "grey" los ntawm qhov tseeb tias lawv cov ntu zoo li grey. Cov qauv metallographic ntawm grey cam khwb cia hlau yog tsim los ntawm flake graphite, hlau matrix thiab grain ciam teb eutectic. Thaum lub sij hawm grey hlau, cov Carbon yog nyob rau hauv flake graphite. Raws li ib qho ntawm cov khoom siv dav siv hlau, cam khwb cia grey hlau muaj ntau qhov zoo ntawm cov nqi, castability thiab machinablity.

Cov yam ntxwv ua tau zoo ntawmGrey Hlau Castings

• Cov kua grey hlau muaj fluidity zoo, thiab nws cov ntim shrinkage thiab linear shrinkage yog me me, thiab qhov rhiab heev rhiab heev yog me me.
• Cov khoom siv kho tshuab qis qis, lub zog compressive yog li 3 ~ 4 npaug siab dua lub zog tensile
• Kev poob siab zoo, qhov kev poob siab ntawm cov hlau grey yog li 10 npaug ntau dua li cov hlau cam khwb cia
• Grey hlau tsis muaj modulus ntawm elasticity

Cov yam ntxwv zoo ntawm Grey Hlau Castings

• Cov phab ntsa me me thiab cov duab nyuaj muaj
• Cov kev ntxhov siab seem ntawm cov casting yog me me
• Grey hlau castings yuav tsum tsis txhob tsim nrog cov qauv tuab heev, thiab cov seem asymmetrical feem ntau yog siv los ua kom tag nrho lawv lub zog compressive.
