Daim ntawv thov ntawm ferrosilicon inoculants: Tam sim no, camshafts ntawm roj av thiab diesel xyaw feem ntau yog ua los ntawm steel, alloy cam khwb cia hlau, thiab ductile hlau, thiab siv quenching los yog txias shock txheej txheem (alloy cam khwb cia hlau txheej txheem) kom tau raws li kev ua tau zoo.Txawm li cas los xij, steel shafts thiab ductile hlau shafts tsis haum rau high-speed engine ntau tshaj 4000 rpm, thiab lub zog ntawm txias-shock alloy cam khwb cia hlau tsis haum rau lub zog yuav tsum tau ntawm nruab nrab-qhov loj engine.
Kev ua haujlwm ntawm ferrosilicon inoculant yog kom kov yeej cov cuab yeej uas twb muaj lawm cov hlau los yog cov khoom siv hlau tsis haum rau cov khoom siv los tiv thaiv kev kub ceev thiab cov khoom txias-shock alloy cam khwb cia hlau cov khoom tsis haum rau cov khoom siv zog ntawm nruab nrab. thiab qis-ceev xyaw, thiab muab ib txoj kev haum rau txhua hom cav.Qhov txias-shock alloy ductile hlau thiab camshaft casting txoj kev uas ua tau raws li qhov yuav tsum tau ua rau lub cav hnav tsis kam, khawb tsis kam, spalling tsis kam, qaug zog taw tes tiv thaiv lub zog, thiab lwm yam. txuag hluav taws xob.Lub ferrosilicon inoculant txais yuav ib txoj kev loj-dose inoculation, thiab tag nrho cov ntsiab lus silicon yog 1.9% -3.7%.Kev ntsuam xyuas ua ntej lub cub tawg qhia tau hais tias cov pa roj carbon sib npaug ntawm cov hlau kub qub, cov pa roj carbon sib npaug ntawm tus neeg sawv cev nodularizing (kev tshuaj xyuas qhov tseeb ntawm qhov kub hnyiab) thiab cov pa roj carbon sib npaug ntawm cov ferrosilicon inoculant (tag nrho qhov nqus ntawm 4.3-4.55. yog smelted nyob rau hauv lub hwj chim zaus los yog nruab nrab zaus rauv, thiab lub cub tawg kub yog 1450 ° C. camshaft casting txoj kev ntawm txias-shock alloy ductile hlau yog ntsuab xuab zeb molding, ntub casting, thiab molding xuab zeb noo noo yog tsawg dua 4%; Qhov ntsuas kub yog 1340-1360 ° C; lub thickness ntawm cov hlau txias sab nraud yog 0.25-0.4 ntawm sab nraud txoj kab uas hla ntawm cam txiv duaj, thiab qhov dav ntawm sab nraud cua txias hlau Qhov dav tib yam li lub cam peach. Cov hlau txias sab nraud yog qhov loj ntawm lub cam txiv duaj tom qab muab faib + 2 npaug ntawm lub thickness ntawm cov hlau txias. Lub puab kab noj hniav ntawm cov cua txias sab nraud yog qhov tseeb radial loj ntawm sab ntawm lub cam txiv duaj lub thawv + 2 hli ntawm ib sab. Lub periphery tuaj yeem ua Txhua yam, nrog txoj kab nqes ntawm 1-2 ° los ntawm hauv qab mus rau saum.
