Tuam Tshoj OEM kev cai cam khwb cia hlau castings los ntawmpoob ciab peev casting txheej txheem. Ductile hlau, uas tseem hu ua ducitle cam khwb cia hlau, nodular hlau, spheroidal graphite hlau, spheroidal graphite cam khwb cia hlau, los yog tsuas yog SG hlau luv luv.Thaum cov graphite tam sim no me me, puag ncig, thiab cov khoom sib 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 khoom siv hlau nplaum yog tsim los ntawm cov txheej txheem casting uas tswj tau 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 yog nce ntxiv los ntawm cov hlau castings.
