Ductile Cast Iron Investment Casting

OEM kev cai ductile cam khwb cia hlau castings nrogpeev casting txheej txheemlos ntawm Tuam Tshoj casting tuam txhab. Peb kuj tuaj yeem muab kev pabcuam ntawmCNC machining, sib dhos thiab kho qhov chaw.

Cam khwb cia hlau yog cov ferrous alloys uas muaj cov ntsiab lus carbon ntau tshaj 2%. Txawm hais tias cam khwb cia hlau tuaj yeem muaj qhov feem pua ​​​​ntawm cov pa roj carbon monoxide ntawm 2 txog 6.67, qhov kev txwv tsis pub muaj feem ntau ntawm 2 thiab 4%. Cov no yog cov tseem ceeb vim lawv zoo heev casting zoo. Grey cam khwb cia hlau thiab ductile cam khwb cia hlau (tseem hu ua nodular cam khwb cia hlau los yog spheroidal graphite hlau) yog feem ntau siv nyob rau hauvcasting qhov chaw.

Cov hlau cam khwb cia hlau yog cov hlau nodularized uas nws cov graphite yog tam sim no me me, puag ncig, thiab cov khoom faib tau zoo, nws cov nyhuv tsis muaj zog yog me me thiab cov cam khwb cia hlau zoo li no yuav muaj ntau dua ductility. Hom cam khwb cia hlau no yog hu ua ductile lossis nodular hlau lossis spheroidal graphite lossis tsuas yog SG hlau. Daim ntawv no ntawm graphite tuaj yeem ua tiav los ntawm kev ntxiv cov ntsiab lus magnesium lossis cerium lossis kev sib xyaw ntawm ob lub ntsiab lus rau molten cam khwb cia hlau. Magnesium yog ntxiv rau hauv qhov ntau ntawm 0.07 mus rau 0. 10% ua raws li qhov sib ntxiv ntawm ferro-silicon los txhawb graphitization. Thaum lub sij hawm solidification, magnesium pab nyob rau hauv kev faib ntawm graphite thoob plaws hauv cov hlau.

Ductile hlau muaj zog-rau-qhov hnyav piv, zoo dua machinability thiab ntau dua qhov cuam tshuam tus nqi. Ntxiv mus, cov hlau nplaum hlau castings yog tsim los ntawm cov txheej txheem casting nyob rau hauv kev tswj kom zoo ntawm cov khoom zoo tuaj yeem ua tiav piv rau kev poob forging. Yog li, ntau yam khoom xws li crankshafts thiab txuas rods tsim feem ntau los ntawm kev poob forging yognce ntxiv los ntawm cov khoom siv hlau ductile.
