65-45-12 ductile hlau poob ciab peev casting qhov chaw

QT65-45-12 ductile hlau QT65-45-12 alloy ductile hlau

Cov khoom siv qib: QT65-45-12

Txuj: GB/T 1348-2009 cov khoom siv hlau

Steel pawg: hlau hlau

QT65-45-12 yog hlau hlau (raws li cov neeg siv yuav tsum tau pom zoo xaiv lwm yam: refining alloy hlau pob)

Ductile hlau yog carbon nyob rau hauv daim ntawv ntawm spherical graphite, nws cov cuab yeej siv tau zoo dua li cov hlau grey thiab ze rau cov hlau, nws muaj qhov zoo casting, txiav thiab hnav tsis kam, muaj qee qhov elasticity,

Nta thiab Scope ntawm daim ntawv thov

Nws yog pearlescent ductile hlau nrog lub zog siab, hnav tsis kam thiab tsis tshua muaj zog (tsis tshua muaj plasticity). Haum rau lub zog siab xav tau ntawm qhov chaw, xws li diesel thiab roj av cav crankshaft, camshaft, ib feem ntawm grinder, milling tshuab, tshuab dhos spindle, pob zeb ncej, me me turbine spindle.

Mechanical zog:

Tensile zog σb (MPa): Ntau dua lossis sib npaug rau 700

Conditional yield zog σ0.2 (MPa): Ntau dua lossis sib npaug rau 420

Elongation δ (%): Ntau dua lossis sib npaug rau 2

Hardness: 225 ~ 305HB

Kev kho cua sov specification thiab metallographic qauv:

Kev kho cua sov specification: (txiav txim siab los ntawm tus neeg muag khoom, cov hauv qab no yog kev kho cua sov ntawm tus qauv, rau kev siv) 800 degree, normalizing

Metallographic qauv: graphite + pearlite + ib qho me me ntawm ferrite

Grey cam khwb cia hlau. Cov ntsiab lus carbon yog siab (2.7% ~ 4.0%), cov pa roj carbon feem ntau muaj nyob rau hauv daim ntawv ntawm flake graphite, thiab tawg yog grey.

Grey hlau luv luv. Tsawg melting point (1145 ~ 1250 degree), me me shrinkage thaum solidification, compressive zog thiab hardness ze rau carbon steel,

Kev poob siab zoo. Siv los tsim cov cuab yeej siv lub txaj, lub tog raj kheej, lub thawv thiab lwm yam khoom siv.

Dawb cam khwb cia hlau. Cov ntsiab lus ntawm carbon thiab silicon yog tsawg, cov pa roj carbon feem ntau muaj nyob rau hauv daim ntawv ntawm cementite, thiab cov pob txha yog nyiaj-dawb. Loj shrinkage thaum lub sij hawm solidification,

Yooj yim los tsim shrinkage qhov thiab tawg. High hardness, brittleness, tsis tuaj yeem tiv taus qhov cuam tshuam. Nws feem ntau yog siv los ua ib qho dawb paug rau malleable cam khwb cia hlau thiab ua rau hnav-resistant qhov chaw.

Malleable cam khwb cia hlau. Tau los ntawm cov hlau cam khwb cia dawb tom qab kho annealing, cov graphite tau muab faib ua pawg thiab flocculation, hu ua hlau tawv. Nws cov ntaub so ntswg zoo sib xws.

Hnav tsis kam, zoo plasticity thiab toughness. Nws yog siv los tsim cov khoom nrog cov duab nyuaj uas tuaj yeem tiv taus cov khoom muaj zog dynamic.

Hlau hlau. Grey cam khwb cia hlau molten hlau yog tau los ntawm spheroidizing kev kho mob, thiab cov precipitated graphite yog spherical, hu ua ductile hlau.

Piv nrog cov grey cam khwb cia hlau zoo tib yam, nws muaj zog dua, zoo dua toughness thiab plasticity. Siv nyob rau hauv kev tsim cov combustion engine, nws pib qhov chaw thiab ua liaj ua teb machinery.

Vermicular graphite cam khwb cia hlau. Cov graphite precipitated los ntawm grey cam khwb cia hlau molten hlau yog worm-zoo li. Mechanical zog zoo ib yam li cov hlau,

Casting zog ntawm grey cam khwb cia hlau thiab ductile cam khwb cia hlau. Siv los ua qhov chaw rau tsheb.

Alloy cam khwb cia hlau. Ordinary cam khwb cia hlau yog tau los ntawm kev ntxiv cov alloying tsim nyog (xws li silicon, manganese, phosphorus, npib tsib xee, chromium, molybdenum, tooj liab, txhuas, boron, vanadium, tin, thiab lwm yam).

Alloying cov ntsiab lus ua rau cov qauv matrix ntawm cam khwb cia hlau hloov, kom nws muaj qhov sib xws thaum tshav kub kub, hnav tsis kam, corrosion kuj, kub tsis kam los yog tsis muaj cov khoom sib nqus. Siv nyob rau hauv kev tsim cov mining, tshuaj machinery thiab cov twj paj nruag, twj paj nruag thiab lwm yam.

Nta: Ua kom tiav cov khoom specifications, nyiam tus nqi, ntim tsis zoo, ntshiab tooj liab, zoo ncaj, cov khoom loj, tuaj yeem muab cov ntaub ntawv pov thawj thiab SGS daim ntawv tshaj tawm.
