A hlau railyog ib qho kev thauj khoom -cov kabmob thiab cov kev taw qhia uas ua rau lub nraub qaum ntawm cov tsheb ciav hlau, ua kom muaj kev nyab xeeb, kav ntev, thiab kev ua haujlwm zoo nyob rau hauv kev tsheb loj thiab kev lag luam. Nws qhov kev ua tau zoo yog txhais los ntawm cov khoom siv, hla -sectional profile, thiab qhov tawv tawv.GNEE RAILmuab tag nrho - qauv kev tsheb nqaj hlau, suav nrog lub teeb thiab hnyav GB rails, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS{10}}–89 kg, BS11: 1985, thiab 2lb-CE, thiab AREMA vuam, kev kho cua sov, thiab tag nrho - kev sib tham txog kev teeb tsa.
115RE Rail Dimensions
115RE rail muaj tus qauv profile raws li AREMA (The American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes). Nws qhov hnyav nominal yog 56.9kg / m sib npaug rau 115 phaus ib yard. Yog li, nws tseem hu ua 115lb rail. Raws li hom kev tsheb ciav hlau hnyav, nws tsuas yog siv rau kev khawb av vim nws lub zog siab . 115RE rail yog cua sov{10}} kho kom tswj tau qhov hardness thiab lub zog ntawm cov hlau. Qhov no yog ua tsaug rau kev kho cua sov ntawm kev tswj cov cua txias thiab yog li tswj cov microstructure.

Dab tsi yog qhov txawv ntawm steel rails ntawm cov qauv sib txawv?
Qhov sib txawv ntawm cov qauv kev tsheb ciav hlau muaj kev hloov pauv hauv cov tshuaj lom neeg, cov khoom siv kho tshuab (lub zog, hardness), qhov hnyav ib meter, profile duab, thiab kev kho cua sov, tag nrho cov tsim nyog rau cov kev siv tshwj xeeb xws li hnyav thauj, siab -ceev, los yog kev lag luam, nrog rau cov qauv loj hauv cheeb tsam xws li UIC (Tebchaws Europe), AREMA (US), thiab JIS (Nyiv) kev nyab xeeb thiab kev ua haujlwm zoo.
Cov yam ntxwv tseem ceeb sib txawv:
Khoom siv & Khoom:
- Carbon Content: Higher carbon (e.g., >0.8%) nce hardness thiab hnav tsis kam tab sis kuj raug nqi, piv rau cov qauv carbon rails.
- Alloying Elements: Ntxiv manganese, silicon, chromium, los yog vanadium txhim kho cov khoom tshwj xeeb xws li lub zog lossis qaug zog.
Mechanical Properties:
- Lub zog & Hardness: Cov qib sib txawv (piv txwv li, R260, 1080) muaj qhov sib txawv tensile lub zog thiab qib hardness, tseem ceeb rau kev tiv thaiv lub log hnav thiab cuam tshuam.
- Toughness: Ib qho tseem ceeb rau kev tiv thaiv kev tsheb ciav hlau tawg, feem ntau ua tiav los ntawm kev tswj kom txias los yog nqus degassing.
Luj & Profile (Size):
- Nyhav ib Meter (kg / m): hnyav rails (piv txwv li, 75kg / m) tuav ntau dua qag loads thiab ceev (heavy haul, mainlines), thaum sib dua rails (piv txwv li, 50kg / m) nplua ceg kab los yog metro.
- Profile Shape: Standardized profiles (lub taub hau, web, ko taw) txawv los ntawm cheeb tsam (UIC, AREMA, thiab lwm yam) kom phim cov qauv tsim tshwj xeeb thiab lub log sib cuam tshuam.
Daim Ntawv Thov & Kev Ua Haujlwm:
- Siab -Speed/Havy Haul: Yuav tsum hnyav dua, muaj zog rails (xws li, UIC 60, AREMA 115RE) kom ruaj khov thiab kav ntev.
- Industrial / Light Rail: Sib dua, kev lag luam ntau dua (piv txwv li, BS 90A) yog siv qhov chaw thauj khoom qis dua.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm cov qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug khoom, GNEE ua tau zoo steel rails uas tau raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
