Hlau rail, tseem hu ua kev tsheb ciav hlau khiav, steel khiav, yog lub ntsiab lus tseem ceeb ntawm txoj kev tsheb ciav hlau. Nws txoj haujlwm yog coj lub log ntawm lub log tsheb, dais lub siab loj ntawm lub log, thiab ua kom ruaj khov ntawm kev tsheb ciav hlau. Txoj kev tsheb ciav hlau yuav tsum muab qhov nruam, du thiab qhov tsawg kawg nkaus dov rau lub log. Nyob rau hauv electrified railway los yog tsis siv neeg thaiv seem, rail kuj yuav siv tau raws li ib tug orbital circuit.
Dab tsi yog qhov zoo tib yam rails ua los ntawm?
Cov tsheb ciav hlau zoo ib yam, tseem hu ua cov pa tsheb ciav hlau, feem ntau yog ua los ntawm cov hlau zoo - zoo uas tuaj yeem tiv taus qhov hnyav tas li, hnav, thiab cuam tshuam ntawm kev hla tsheb ciav hlau. Kev xaiv ntawm cov hlau ua kom cov tsheb ciav hlau muaj zog, toughness, thiab durability.

Vim li cas hlau siv rau Ordinary Rails?
- Lub zog: Hlau muab lub zog txhua yam tsim nyog los txhawb nqa hnyav locomotives thiab tsheb thauj khoom.
- Durability: Resistant hnav thiab deformation nyob rau lub sijhawm ua haujlwm ntev.
- Toughness: tuaj yeem nqus cov cuam tshuam yam tsis muaj kev tawg.
- Fatigue Resistance: Tuav lub tsheb ciav hlau rov qab thauj mus los yam tsis muaj kev ua haujlwm
Yuav ua li cas xaiv cov khoom siv rail?
Xaiv txoj kev tsheb ciav hlau txoj kev tsheb ciav hlau yuav suav nrog kev sib tw ntawm txoj kev tsheb ciav hlau cov khoom (qhov hnyav, lub zog, hardness, profile) rau daim ntawv thov kev thov, tsom rau lub qag load, tsheb ntim, kev khiav hauj lwm ceev, nkhaus vojvoog, thiab ib puag ncig, nrog hnyav, hnyav, los yog alloy steels rau siab -ceev / hnyav- cov kab thiab zoo li siv cov qauv kev sib tw nrog IC. AREMA.
- Ntsuam xyuas Loads & Ceev: Txiav txim siab qhov profile (MGT, qag loads, ceev).
- Kos kab Geometry: Txheeb xyuas cov nkhaus nruj thiab cov qib siab.
- Xav txog ib puag ncig: Qhov cuam tshuam rau huab cua thiab kev pheej hmoo corrosion.
- Xaiv Profile & Qib: Sib piv rau cov kev xav tau (xws li UIC60 rau mainlines, P24 / P30 rau lub teeb crane).
- Tham nrog cov kws tshaj lij: Ua haujlwm nrog cov neeg muag khoom thiab cov kws tsim khoom kom pom kev xaiv thiab ua raws li cov qauv.
Raws li cov chaw tsim khoom ntawm rail Cheebtsam los ntawm Tuam Tshoj,GNEE RAILxav qhia lub Tuam Tshoj steel rails rau koj! Rau cov xwm txheej sib txawv, peb yuav tsum xaiv qhov tsim nyog steel rails. Steel rails muaj ntau hom thiab qauv xaiv.
