Dab tsi yog steel rail?
Lub tsheb ciav hlau steel yog ib qho tshwj xeeb zoo li tus, siab - lub zog steel bar tsim cov kev taw qhia tseem ceeb thiab thauj khoom - bearing nto ntawm railway lem, muab txoj kev du rau cov tsheb ciav hlau, cranes, thiab lwm yam tsheb coj, thaum tiv taus siab loj thiab hloov mus rau cov neeg pw tsaug zog (kev sib txuas). Cov "I" lossis "U" - cov duab zoo li no muaj qhov ruaj khov, tsis tu ncua, thiab qis- ua haujlwm dov nto, feem ntau yog ua los ntawm nruab nrab mus rau siab carbon steel rau hardness, toughness, thiab hnav tsis kam, nrog rau cov qauv tshwj xeeb rau siab -cov neeg caij tsheb ceev, thauj khoom hnyav, lossis cov cranes muaj.
Steel Rail Classification
Txoj kev tsheb ciav hlau yog qhov tseem ceeb ntawm txoj kev tsheb ciav hlau, thiab lub luag haujlwm yog coj lub tsheb log mus rau pem hauv ntej, tiv taus lub zog loj ntawm lub log thiab hloov mus rau cov neeg pw tsaug zog. Cov steel rails tau muab faib ua peb hom,crane rail, hnyav rail thiab lub teeb rail.
- Hom crane rail: QU120, QU100, QU80, QU70, cov khoom yog manganese steel.

| 60 KG / M | 176 | 73 | 150 | 16.5 | 60.64 | |
- Hom teeb pom kev zoo: 9,12,15,22,30kg / m.
| Kev faib tawm | Qhov siab (mm) | Lub taub hau (mm) | Hauv qab (mm) | Thickness (mm) | Qhov hnyav (kg / m) | |
| Lub Teeb Rail | 8 KG / M | 65 | 25 | 54 | 7 | 8.42 |
| 9 KG / M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |

| 30 KG / M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
Cov tsheb ciav hlau sib txawv muaj cov qauv ntev. Txhua hom kev tsheb ciav hlau xav tau qhov tshwj xeeb lossis sib txuam steel rail. Xws li kev teeb tsa ntawm cov tsheb ciav hlau tawg, nws yuav tsum tau hloov tam sim ntawd los tiv thaiv kev nyab xeeb ntawm tsheb. Tshawb xyuas cov tsheb ciav hlau tsis tu ncua txhawm rau txhawm rau tshem tawm cov teeb meem zais. Nws yog ib qho tsim nyog los xaiv thiab nruab qhov zoo, siab hnav tsis kam steel rails.
Lub hom phiaj ntawm Track Rail yog dab tsi?
Lub hom phiaj ntawm txoj kev tsheb ciav hlau yog los txhawb, qhia, thiab muab qhov chaw qis - kev sib txhuam rau cov tsheb ciav hlau, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj mus los los ntawm kev faib cov khoom hnyav, tswj kev taw qhia, thiab tiv thaiv derailments, tsim cov qauv tseem ceeb rau dov Tshuag mus rau.
Lub luag haujlwm tseem ceeb:
- Kev them nyiaj yug: Rails nqa qhov hnyav hnyav ntawm tsheb ciav hlau, faib nws hla cov neeg pw tsaug zog (kev sib raug zoo) thiab ballast.
- Kev taw qhia: Lawv muab cov lus qhia txuas ntxiv mus, ua kom cov log sib dhos thiab tiv thaiv lub tsheb ciav hlau los ntawm txoj kev.
- Low Friction Surface: Steel rails muab ib tug du, nyuaj nto rau steel log rau dov rau, txo qhov kev tiv thaiv kom sai, ntau yig mus txawv tebchaws.
- Load Distribution: Lawv kis tau lub zog ntsug thiab kab rov tav los ntawm lub tsheb ciav hlau sib npaug mus rau lub txaj txhawb nqa.
- Kev Taw Qhia: Rails txhais txoj hauv kev ntawm lub tsheb ciav hlau, tso cai rau kev tswj kev txav thiab hloov mus.
- Kev Nyab Xeeb: Lawv yog ib qho tseem ceeb rau kev ruaj ntseg, nrog cov yam ntxwv zoo li kev nyab xeeb ntawm cov choj thiab cov nkhaus kom muaj lub tsheb ciav hlau yog tias nws derails.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm ntau 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 cov cuab yeej, GNEE ua tau zoo steel rails 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.
