Classification Ntawm Cast Iron

1, Raws li cov ntaub ntawv sib txawv ntawm cov pa roj carbon monoxide, cam khwb cia hlau tuaj yeem muab faib ua

Dawb cam khwb cia hlau

Tsuas yog ib qho me me ntawm cov pa roj carbon diluted hauv ferrite, cov khoom seem ntawm cov pa roj carbon monoxide muaj nyob rau hauv cov hlau cam khwb cia hauv daim ntawv ntawm cementite, thiab nws cov pob txha yog nyiaj dawb, yog li nws hu ua dawb cam khwb cia hlau. Tam sim no, dawb cam khwb cia hlau yog tsuas yog siv los ua raw khoom rau steel ua thiab dawb paug rau ua malleable cam khwb cia hlau.

Grey cam khwb cia hlau

Tag nrho los yog feem ntau ntawm cov pa roj carbon monoxide muaj nyob rau hauv cov hlau cam khwb cia li flake graphite, thiab nws cov pob txha yog grey tsaus, yog li nws yog hu ua grey cam khwb cia hlau.

Hemp cam khwb cia hlau

Ib feem ntawm carbon muaj nyob rau hauv daim ntawv ntawm graphite, zoo ib yam li grey cam khwb cia hlau; Lwm qhov muaj nyob rau hauv daim ntawv ntawm dawb cementite, zoo ib yam li dawb cam khwb cia hlau. Muaj cov xim dub thiab dawb hauv qhov tawg, yog li nws hu ua ma cam khwb cia hlau. Hom cam khwb cia hlau no kuj nyuaj thiab nkig, yog li nws tsis tshua siv hauv kev lag luam.

2, Raws li cov ntaub ntawv sib txawv graphite hauv cam khwb cia hlau, cam khwb cia hlau tuaj yeem muab faib ua

Grey cam khwb cia hlau

Graphite nyob rau hauv cam khwb cia hlau muaj nyob rau hauv flakes.

hlau hlau

Graphite nyob rau hauv cam khwb cia hlau muaj nyob rau hauv daim ntawv ntawm flocs. Nws yog ua los ntawm dawb cam khwb cia hlau nrog tej yam muaj pes tsawg leeg tom qab annealing ntawm high kub rau lub sij hawm ntev. Nws cov khoom siv kho tshuab (tshwj xeeb yog toughness thiab plasticity) yog siab dua li cov hlau cam khwb cia hlau, yog li nws yog conventionally hu ua malleable cam khwb cia hlau.

Hlau hlau

Graphite hauv cam khwb cia hlau yog spherical. Nws yog tau tom qab spheroidizing kev kho mob ua ntej pouring hlau molten. Hom cam khwb cia hlau no tsis tsuas yog muaj cov khoom siv ntau dua li cov cam khwb cia hlau grey thiab malleable cam khwb cia hlau, tab sis kuj muaj cov txheej txheem tsim khoom yooj yim dua li malleable cam khwb cia hlau. Ntxiv mus, nws tuaj yeem txhim kho nws cov khoom siv kho tshuab los ntawm kev kho cua sov, yog li nws tau siv dav hauv kev tsim khoom.
