Kev cai Grey Cast Iron Sand Casting

Thaum peb nrum grey hlau, peb nruj me ntsis ua raws li cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom raws li lub stardards los yog yuav tsum tau los ntawm cov neeg muas zaub. Tsis tas li ntawd, peb muaj peev xwm thiab cov cuab yeej siv los kuaj seb puas muaj qhov tsis xws luag hauv qhov castinggrey hlau xuab zeb castings.

Cov ferrous alloys uas muaj cov ntsiab lus ntawm ntau tshaj 2% yog hu ua cam khwb cia hlau. Txawm hais tias cam khwb cia hlau tuaj yeem muaj qhov feem pua ​​​​ntawm cov pa roj carbon monoxide ntawm 2 txog 6.67, qhov kev txwv tsis pub muaj feem ntau ntawm 2 thiab 4%. Cov no yog cov tseem ceeb vim lawv zoo heev casting zoo.

Grey hlau castings yog pheej yig duahlau castings, tab sis nws muaj zog tensile thiab ductility ntau dua li cov hlau. Grey hlau tsis tuaj yeem hloov cov pa roj carbon steel, thaum cov hlau nplaum tuaj yeem hloov cov pa roj carbon steel hauv qee qhov xwm txheej vim muaj lub zog tensile siab, tawm dag zog thiab elongation ntawm cov hlau hlau.

Los ntawm daim duab hlau-carbon equilibrium, nws tuaj yeem pom tias cov hlau cam khwb cia muaj qhov tseem ceeb ntawm cementite thiab ferrite. Vim tias qhov feem pua ​​​​ntawm cov pa roj carbon ntau dua, cov cementite yog siab ua rau muaj kev nyuaj siab heev thiab brittleness zoo rau cam khwb cia hlau.
