Dab tsi ntawm casting yog siv rau iav?

1, Txheej txheem cej luam ntawm Gear Casting Materials
Muaj ntau yam khoom siv rau iav castings, uas tuaj yeem muab faib ua ob pawg raws li cov khoom siv: hlau castings thiab non-metallic castings. Hauv cov hlau castings, feem ntau suav nrog cam khwb cia hlau, cam khwb cia hlau, cam khwb cia tooj liab, thiab lwm yam; Cov khoom siv tsis yog xim hlau muaj xws li yas, roj hmab, thiab lwm yam. Cov ntaub ntawv no txhua tus muaj lawv tus kheej cov yam ntxwv thiab tsim nyog rau qhov chaw ua haujlwm sib txawv thiab cov kev xav tau ntawm kev sib kis.
2, Kev Siv Hlau Castings hauv Gears
Cam khwb cia steel gears
Cam khwb cia hlau iav yog dav siv nyob rau hauv hnyav-duty thiab high-ceev kis scenarios vim lawv lub zog siab, siab hardness, thiab zoo heev hnav tsis kam. Cam khwb cia hlau cov ntaub ntawv tuaj yeem txhim kho lawv cov khoom siv kho tshuab ntxiv, ua kom cov kabmob muaj peev xwm thiab kev pabcuam lub neej ntawm cov iav los ntawm kev kho cua sov. Txawm li cas los xij, tus nqi tsim khoom ntawm cam khwb cia steel iav yog siab thiab kev ua haujlwm nyuaj kuj tseem ceeb.
Cam khwb cia hlau iav
Cam khwb cia hlau iav yog dav nyiam vim lawv qhov zoo xws li tus nqi qis, zoo hnav tsis kam, thiab zoo casting thiab txiav txheej txheem. Cam khwb cia hlau iav tuaj yeem muab faib ua grey cam khwb cia hlau iav, malleable cam khwb cia hlau iav, thiab ductile hlau iav. Grey cam khwb cia hlau iav yog haum rau qhov qis-ceev thiab du kis tau tus mob; Malleable cam khwb cia hlau iav muaj ib qho kev toughness thiab yog haum rau withstanding tej yam loads; Ductile hlau iav yog dav siv nyob rau hauv hnyav-duty thiab high-speed kis daim ntaub ntawv vim lawv lub zog siab, siab hardness, thiab zoo hnav tsis kam.
Grey cam khwb cia hlau iav yog hom cam khwb cia hlau ntau tshaj plaws. Tag nrho los yog feem ntau ntawm nws cov pa roj carbon monoxide muaj nyob rau hauv daim ntawv ntawm flake graphite, thiab cov pob txha tawg yog grey. Txawm hais tias graphite muaj cov khoom siv tsis zoo, vim nws qhov zoo xws li tus nqi qis thiab hnav tsis kam, grey cam khwb cia hlau iav tseem siv dav hauv cov xwm txheej qis thiab kev sib kis.
Malleable cam khwb cia hlau iav yog ua los ntawm dawb cam khwb cia hlau los ntawm graphitization annealing. Nws cov carbon muaj nyob rau hauv daim ntawv ntawm flocculent graphite nyob rau hauv lub matrix, nrog siab toughness thiab hnav tsis kam. Malleable cam khwb cia hlau iav yog tsim rau cov xwm txheej uas tiv taus qee yam kev cuam tshuam.
Cov hlau nplaum hlau yog tsim los ntawm spheroidization ntawm molten hlau, nyob rau hauv uas tag nrho los yog feem ntau ntawm cov graphite nyob rau hauv cam khwb cia hlau yog faib nyob rau hauv ib tug kheej kheej zoo ntawm lub substrate. Piv nrog flake graphite, spherical graphite zoo heev txo cov kev ntxhov siab vim los ntawm graphite carbon, muab zog ntau dua txhua yam khoom thiab hnav tsis kam. Ductile hlau iav yog haum rau hnyav-duty thiab high-ceev kis xwm txheej.
3, Daim ntawv thov ntawm cov hlau tsis yog hlau castings hauv lub zog
Tsis yog xim hlau castings xws li yas thiab roj hmab kuj siv rau hauv kev tsim khoom. Cov ntaub ntawv no muaj qhov zoo xws li lub teeb yuag, tsis muaj suab nrov, thiab kev poob siab zoo, ua rau lawv haum rau kev kub ceev, lub teeb load, thiab tsis tshua muaj precision kis scenarios. Txawm li cas los xij, lub peev xwm thauj khoom thiab hnav tsis kam ntawm cov iav tsis yog hlau tsis zoo, yog li lawv cov kev ua tau zoo thiab cov nqi yuav tsum tau muab xam rau hauv kev siv tswv yim.
