Ductile hlau manhole npog: tuaj yeem pom raws li matrix ntawm carbon steel nrog flake graphite.Raws li cov qauv matrix sib txawv, grey cam khwb cia hlau tuaj yeem muab faib ua peb pawg: ferrite matrix grey cam khwb cia hlau;Ferrite pearlite raws li grey cam khwb cia hlau;Pearlite raws li grey cam khwb cia hlau.
Mechanical Properties Of Ductile Iron Manhole Npog
Cov khoom siv ntawm cov hlau grey muaj feem xyuam nrog microstructure ntawm matrix thiab morphology ntawm graphite.Lub flaky graphite nyob rau hauv grey cam khwb cia hlau hnyav cleaves lub matrix, yooj yim ua rau muaj kev ntxhov siab nyob rau hauv lub ntse ces kaum ntawm graphite, ua lub tensile lub zog, plasticity, thiab toughness ntawm grey cam khwb cia hlau ntau qis dua cov hlau.Txawm li cas los xij, nws lub zog compressive yog sib npaug ntawm cov hlau, thiab nws tseem yog cov hlau cam khwb cia nrog cov khoom siv tsis zoo ntawm cov khoom siv cam khwb cia hlau.Nyob rau tib lub sijhawm, cov qauv matrix kuj muaj qee yam cuam tshuam rau cov khoom siv hluav taws xob ntawm grey cam khwb cia hlau.Cov graphite flakes ntawm ferrite matrix grey cam khwb cia hlau yog ntxhib, nrog lub zog qis thiab hardness, yog li lawv tsis tshua siv;Cov graphite flakes ntawm pearlite raws li grey cam khwb cia hlau yog me me, muaj zog thiab hardness, thiab tsuas yog siv los tsim cov khoom tseem ceeb dua;Cov graphite flakes ntawm ferrite pearlite matrix grey cam khwb cia hlau yog me ntsis thicker dua pearlite grey cam khwb cia hlau, thiab lawv cov kev ua tau zoo tsis zoo li pearlite grey cam khwb cia hlau.Yog li ntawd, grey cam khwb cia hlau nrog pearlite matrix feem ntau siv hauv kev lag luam.
Lwm Cov Khoom Ntawm Cov Hlau Hlau Manhole Npog
Kev ua haujlwm zoo casting, zoo poob siab, zoo hnav tsis kam, zoo txiav kev ua tau zoo, tsis tshua muaj notch rhiab heev.

Kev kho cua sov ntawm Grey Cast Iron Manhole Cover
1. Ductile hlau manhole npog nrog kev ntxhov siab nyem annealing.
2. Nodular cam khwb cia hlau manhole npog txhim kho machinability annealing.
3. Nto quenching ntawm ductile hlau manhole npog.
