1. Cam khwb cia hlau li qub
Cam khwb cia hlau li qub yog siv los nchuav cov hlau castings. Ib hom casting alloy. Cam khwb cia hlau yog cov hlau casting uas tsim los ntawm txoj kev casting. Cam khwb cia hlau yog tsuas yog siv nyob rau hauv kev tsim khoom ntawm ib co complex duab, nyuaj rau forge los yog txiav txheej txheem tsim thiab yuav tsum tau muaj zog thiab plasticity ntawm qhov chaw.
2. Cam khwb cia hlau li qub
Cam khwb cia hlau yog cov ntsiab lus carbon ntau tshaj 2% ntawm cov hlau-carbon alloy. Feem ntau peb hu ua cam khwb cia hlau li qub, nrog cov hlau ductile, grey cam khwb cia hlau hlau los ntawm spheroidal kho tau, nag lossis daus ntawm graphite yog spherical, hu ua ductile hlau. Tshaj li qhov zoo tib yam grey cam khwb cia hlau muaj zog dua, zoo toughness thiab plasticity.
Classification ntawm cam khwb cia hlau li qub:
cam khwb cia hlau yuav muab faib ua: grey cam khwb cia hlau, dawb cam khwb cia hlau, malleable cam khwb cia hlau, ductile hlau, peristaltic cam khwb cia hlau, alloy cam khwb cia hlau.
3. Distinction:
Thawj cov khoom sib txawv, ib qho yog cam khwb cia hlau, ib qho yog cam khwb cia hlau.
Qhov thib ob, lub siab tsis kam ntawm qhov nruab nrab yog qhov sib txawv, cam khwb cia hlau yog lub siab-siab valve, cam khwb cia hlau yog lub valve qis.
Thib peb, lub sealing tsis zoo ib yam, cam khwb cia steel valve sealing kev ua tau zoo dua li cam khwb cia hlau valve.
Plaub, kev siv cov khoom sib txawv, cam khwb cia steel li qub tuaj yeem siv rau qhov kub thiab txias ib puag ncig, cam khwb cia hlau li qub tsuas yog siv rau hauv qhov kub thiab txias, qhov chaw tsis tshua muaj siab.
cam khwb cia hlau li qub yog siv nyob rau ntawm qhov kub ntawm txog 125 degrees, haum rau kais dej, dej phwj tuaj thiab lwm yam uas tsis yog-kua kua siv; cam khwb cia steel li qub tuaj yeem siv rau ntawm qhov kub siab tshaj ntawm 425 degrees, haum rau siv hauv boilers, chav kav dej.
cam khwb cia hlau yog nruj dua li cam khwb cia hlau, brittleness kuj yog ntau dua cam khwb cia hlau, thiab cam khwb cia hlau muaj zoo plasticity thiab toughness dua cam khwb cia hlau, yog li cam khwb cia hlau feem ntau yog siv nyob rau hauv lub pipeline ntawm qis siab, tab sis kuj tsuas yog siv tau rau lub cam khwb cia hlau. pipeline nyob rau hauv chav tsev kub saum toj no, vim hais tias ntawm lub siab los yog kub nce yuav qhia tau hais tias lub valve yuav muaj ib tug npaum li cas ntawm deformation ntawm ib tug kab ntawm cam khwb cia hlau li qub yog unfavorable.
Cov txheeb ze rau cam khwb cia hlau li qub, cam khwb cia steel li qub tuaj yeem siv rau hauv qhov siab lossis qhov kub thiab txias yog qhov siab ntawm cov kav dej.
