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.
22 kq rwjyog oriented thiab load bearing, nws yog siv nrog lub log khiav, txhawb nqa qhov hnyav.Lub 22kg lub teeb rail yog tsuas yog siv rau kev tso cov kab tsheb thauj mus los ib ntus thiab lub teeb locomotive kab rau thaj chaw hav zoov, thaj chaw mining, factories thiab chaw tsim kho.
Ib tug 22kg lub teeb steel rail hnyav22.3 kg ib m(kg / m), raws li "22kg" yog hais txog nws qhov hnyav nominal ib 'meter', uas yog tus qauv rau hom kev tsheb ciav hlau no siv hauv kev siv mining thiab kev lag luam. Thaum nws qhov kev ntsuas qhov hnyav yog 22.3 kg / m, qhov ntsuas qhov ntsuas tau qee zaum txawv me ntsis (piv txwv li, 21.2-21.5 kg / m) vim yog kev tsim khoom.

Heavy steel rail vs Lub teeb rail
Hnyav rail siv loj, muaj zog rails rau siab -ceev, siab - muaj peev xwm systems (subways, freight) rau lem, thaum lub teeb rail siv sib dua, me rails rau hauv nroog thauj (trams) uas feem ntau khiav ntawm txoj kev theem, tej zaum sib koom txoj kev nrog tsheb, muab tsawg dua tab sis yooj yim dua. Qhov sib txawv tseem ceeb yog nyob rau hauv qhov hnyav hnyav (piv txwv li, 60kg + rau hnyav vs.<30kg for light), infrastructure (grade-separated vs. at-grade), capacity, and operational environment (dedicated vs. mixed traffic).
| Kev faib tawm | Qhov siab (mm) | Lub taub hau (mm) | Hauv qab (mm) | Thickness (mm) | Qhov hnyav (kg / m) | |
| Heavy Rail | 38 KG / M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG / M | 140 | 70 | 114 | 14.5 | 44.653 | |

| 50 KG / M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG / M | 176 | 73 | 150 | 16.5 | 60.64 | |
Lub luag haujlwm ntawm steel rail yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm steel rails yog muab qhov chaw du, nruam, thiab ruaj khov uas coj lub log tsheb ciav hlau, txhawb nqa qhov hnyav, thiab hloov cov khoom thauj los ntawm lub log mus rau cov qauv khiav (pw tsaug zog, ballast, roadbed). Lawv muaj qhov tsawg- txoj kev tiv thaiv rau dov, tiv taus qhov cuam tshuam thiab siab, thiab, hauv cov tshuab hluav taws xob, kuj tuaj yeem ua cov khoom hluav taws xob rau cov teeb liab thiab lub zog.
- Kev taw qhia: Rails khaws cov tsheb ciav hlau ntawm txoj kev tshwj xeeb, tiv thaiv kev derailment thiab ua kom muaj kev nyab xeeb.
- Load Support: Lawv dais qhov hnyav hnyav ntawm locomotives thiab carriages, faib nws hla cov qauv khiav.
- Load Transfer: Rails xa cov rog no (qhov hnyav, cuam tshuam, lub zog centrifugal) rau cov neeg pw tsaug zog thiab hauv av hauv qab no.
- Tsawg Resistance Surface: Lawv muab qhov tsawg tshaj plaws tiv thaiv nto rau lub log kom yob rau, ua kom lub tsheb ciav hlau khiav tau zoo.
- Kev Siv Hluav Taws Xob: Ntawm cov kab hluav taws xob, lawv ua ib feem ntawm cov hluav taws xob hluav taws xob rau kev taw qhia thiab lub zog rov qab.
