Dab tsi yog Cov Khoom Siv Txheej Txheem rau 54E1 Rail?
Cov54 E1 Rail(keeb kwm hu ua UIC54) yog ib qho ntawm feem ntau siv railway khiav profiles nyob rau hauv lub ntiaj teb no. Txawm hais tias koj tab tom tsim cov kab tsheb thauj neeg caij tsheb loj lossis hnyav - thauj khoom thauj khoom thauj, xaiv cov qib steel zoo yog qhov tseem ceeb rau kev taug qab kev nyab xeeb, lub neej ntev, thiab cov nqi tu.
1. Cov Qib Hlau Raws li European Standard (EN 13674-1)
Raws li European tus qauv EN 13674-1, cov ntaub ntawv rau 54E1 rail yog feem ntau cais los ntawm hardness thiab tensile lub zog. Ob qib tseem ceeb tshaj plaws yog:
Qib R260: Tus Qauv Kev Lag Luam (Tsis yog-Tshuaj Kub)
- Yam ntxwv: R260 yog "raws li-rolled" carbon-manganese steel. Nws yuav tsum muaj qhov tsawg kawg nkaus hardness ntawm260 HWBthiab qhov tsawg kawg nkaus tensile lub zog ntawm880 MPa ua.
- Daim ntaub ntawv: Qhov no yog cov khoom siv tshaj plaws rau 54E1 rails thoob ntiaj teb. Nws yog dav siv rau cov kev tsheb ciav hlau loj loj, cov neeg caij tsheb sib xyaw- tsheb thauj mus los, thiab cov kab ncaj nraim lossis loj - vojvoog nkhaus.
Qib R350HT: Lub Hnyav -Kev Xaiv Lub Luag Haujlwm (Kub Kho)
- Yam ntxwv: "HT" sawv cev rau Kev Kho Hniav Kub. Los ntawm cov txheej txheem quenching hauv online, nws qhov hardness yam tsawg kawg nkaus ncav cuag 350 HBW, nrog lub zog tensile yam tsawg kawg nkaus ntawm 1175 MPa.
- Daim ntawv thov: R350HT muaj qhov tshwj xeeb hnav thiab qaug zog ua haujlwm. Nws yog tsim tshwj xeeb rau hnyav- txoj kev tsheb ciav hlau, siab - cov kab tsheb khiav ceev, thiab cov nkhaus ntse uas sab hnav yog qhov kev txhawj xeeb loj.

2. Sib npaug Suav Cov Qauv (GB/T 2585)
Sib npaug rau EN R260: U71Mn
U71Mn yog classic high-carbon, micro-manganese rail hlau hauv Suav teb. Nws lub zog tensile (Ntau dua los yog sib npaug rau 880 MPa) thiab hardness (260 ~ 300 HBW) zoo kawg nkaus phim European R260 tus qauv.
(Faj seeb: U75V, uas muaj vanadium, yog ib qho nyuaj me ntsis thiab feem ntau siv los ua lwm yam zoo rau cov uas tsis yog - cua sov- kho cov cai).
Sib npaug rau EN R350HT: U71MnQ lossis U75VQ
Cov lus "Q" txhais tau tias Quenched (kub-kho). Thaum U71Mn lossis U75V tau txais kev kho cua sov, lawv cov tawv tawv ncav cuag 320 ~ 380 HBW, nrog lub zog tensile Ntau dua lossis sib npaug rau 1180 MPa.
Cov qib no yog cov qauv tsim thiab tshuaj zoo tshaj plaws hloov pauv rau European R350HT hauv cov haujlwm hnyav-.
