Cov tshuaj muaj pes tsawg leeg ntawm cov hlau nplaum feem ntau suav nrog tsib lub ntsiab lus ntawm carbon, silicon, manganese, sulfur thiab phosphorus. Rau qee qhov castings nrog tshwj xeeb yuav tsum tau ntawm lub koom haum thiab kev ua tau zoo, ib qho me me ntawm cov ntsiab lus alloying kuj suav nrog. Tsis zoo li cov hlau zoo tib yam grey cam khwb cia hlau, cov hlau nplaum yuav tsum muaj cov lej ntawm cov seem spheroidal nyob rau hauv thiaj li yuav xyuas kom meej graphite spheroidization. Peb tsim ntau yam ntawmcastings rau Japanese thiab European tsheb thauj khoom, zoo licaij nplooj ntoos hlav bracket, caij nplooj ntoos hlav shackle,caij nplooj ntoos hlav pin thiab caij nplooj ntoos hlav bushing.
1, Carbon thiab carbon sib npaug xaiv txoj cai: carbon yog lub hauv paus ntsiab lus ntawm ductile hlau, siab carbon pab graphitization. Txawm li cas los xij, cov ntsiab lus carbon siab yuav ua rau graphite ntab. Yog li ntawd, qhov kev txwv sab saud ntawm cov pa roj carbon sib npaug hauv cov hlau ductile yog raws li lub hauv paus ntsiab lus ntawm tsis muaj graphite ntab.
2, Silicon xaiv txoj cai: Silicon yog lub zog graphitizing. Nyob rau hauv cov hlau ductile, silicon tuaj yeem tsis tsuas yog txo qhov nyiam ntawm lub qhov ncauj dawb thiab nce cov nyiaj ntawm ferrite, tab sis kuj muaj lub luag haujlwm ntawm refining eutectic pawg thiab txhim kho lub roundness ntawm graphite spheres.
3, Manganese xaiv txoj cai: Raws li cov ntsiab lus ntawm sulfur nyob rau hauv ductile hlau twb tsawg heev, tsis tas yuav tsum tau ntau manganese rau neutralize sulfur, lub luag hauj lwm ntawm manganese nyob rau hauv ductile hlau yog tsuas yog nyob rau hauv kev txhim kho stability ntawm pearlite.
4, Phosphorus xaiv cov hauv paus ntsiab lus: phosphorus yog ib qho teeb meem, nws tsis tshua muaj solubility hauv cam khwb cia hlau. Feem ntau, qhov qis dua cov ntsiab lus ntawm phosphorus hauv cov hlau hlau, qhov zoo dua.
5, Sulfur xaiv txoj cai: Sulfur yog ib qho kev tiv thaiv kheej kheej, nws muaj zog affinity nrog magnesium, tsawg lub ntiaj teb thiab lwm yam spheroidal ntsiab, lub xub ntiag ntawm leej faj yuav noj ntau spheroidal ntsiab nyob rau hauv lub ferrofluid, tsim magnesium thiab tsawg. ntiaj teb sulfides, ua rau slag, porosity thiab lwm yam casting tsis xws luag.
6, Spheroidal ntsiab lus xaiv txoj cai: nyob rau hauv lub hauv paus ntawm kev ua kom lub spheroidal tsim nyog, cov seem ntawm magnesium thiab tsawg lub ntiaj teb yuav tsum tsawg li tsawg tau. Magnesium thiab tsis tshua muaj lub ntiaj teb residues siab dhau lawm, yuav ua rau muaj kev nyiam ntawm lub qhov ncauj dawb ntawm cov kua hlau, thiab yuav cuam tshuam rau cov khoom siv hluav taws xob ntawm cov castings vim lawv qhov sib cais ntawm cov ciam teb.
