Cov qauv ntawm cov khoom siv casting feem ntau suav nrog cov hauv qab no:
Grey cam khwb cia hlau: Grey cam khwb cia hlau yog siv dav tshaj plaws thiab siab tshaj - hom cam khwb cia hlau, suav txog ntau dua 80% ntawm kev lag luam. Nws muaj flake graphite, siab compressive zog, tab sis kuj tsis tshua muaj zog tensile. Grey cam khwb cia hlau yog qhov rhiab heev rau qhov txias txias, thiab cov kev hloov ntawm phab ntsa thickness muaj qhov cuam tshuam loj rau nws cov khoom siv kho tshuab. Vim nws tsis zoo thermal stability, nws tsis haum rau siv nyob rau hauv siab - qhov kub thiab txias.
Vermicular graphite cam khwb cia hlau: Lub graphite morphology ntawm vermicular graphite cam khwb cia hlau yog nruab nrab ntawm flake thiab kheej kheej, uas qhia ib tug kab mob. Nws cov khoom siv dav dav zoo dua li cov grey cam khwb cia hlau, thiab nws yog qhov tsim nyog rau kev tsim cov khoom hauv qhov chaw hnyav, tshwj xeeb tshaj yog cov kub kub gradients. Vermicular graphite cam khwb cia hlau tsis tshua muaj siab rau qhov txias txias thiab muaj cov thermal conductivity zoo thiab cov txheej txheem ua haujlwm.
Spheroidal graphite cam khwb cia hlau: Ductile cam khwb cia hlau yog tau los ntawm tshwj xeeb spheroidizing thiab inoculation kev kho mob, thiab cov graphite yog spherical. Nws txoj kev ua tau zoo yog piv rau cov hlau, thiab nws lub zog, plasticity thiab elastic modulus zoo dua li cov hlau cam khwb cia grey, thiab nws cov hnav tsis kam kuj yog siab dua. Txawm hais tias rhiab rau qhov txias txias, nws cov thermal stability siab ua rau nws siv tau rau hauv qhov kub thiab txias.
Casting alloy cov ntaub ntawv: xws li ZG40Cr9Si2, uas belongs rau lub siab chromium cam khwb cia hlau qeb, feem ntau yog siv los tsim cov khoom uas tiv taus kub, siab kub thiab muaj zog hnav. Cov khoom siv no muaj kev tiv thaiv zoo heev thiab hnav tsis kam.
