Hom kev tsheb ciav hlau feem ntau yog dab tsi?
Jan 15, 2026
Hlau rail(tseem hu ua railroad rails, railway rails, los yog crane rails) yog cov khoom tseem ceeb ntawm cov kab ke, pab coj lub log thiab faib cov khoom hnyav nrog qhov tseeb.
Hom kev tsheb ciav hlau feem ntau yog dab tsi?
Lub steel rail yog ib qho kub -khoov steel seem ntsia longitudinally ntawm sleepers los ua qhov chaw khiav ntawm lub tsheb ciav hlau log, hloov qag loads rau hauv cov qauv khiav, thiab tswj kom raug cov kev taw qhia ntawm dov Tshuag. Hauv kev tsim kho tsheb ciav hlau niaj hnub no, cov tsheb ciav hlau tsis yog cov tswv cuab nkaus xwb tab sis tseem yog qhov tseem ceeb ntawm kev qaug zog - cov khoom tseem ceeb uas nws qhov profile, qib steel, thiab kev kho cua sov ncaj qha txiav txim siab taug qab lub neej thiab kev tu lub voj voog. Thoob plaws ntiaj teb kev tsheb ciav hlau sib txuas, txawm hais tias muaj ntau qhov profile thiab cov qauv muaj nyob, ib pawg tau dhau los ua qhov tseem ceeb hauv cov neeg caij tsheb thiab cov khoom thauj.
Dab tsi yog Qhov Kev Siv Hluav Taws Xob Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Niaj Hnub No?
Hom kev tsheb ciav hlau uas siv thoob ntiaj teb feem ntau yog covtiaj tus- hauv qab hnyav tsheb ciav hlau, tshwj xeeb tshaj yog cov profiles nyob ib ncig ntawm 60 kg / m, xws li UIC60, 60E1 (EN), 60kg (GB), thiab 136RE (AREMA, muaj peev xwm zoo sib xws). Pav ca - cov kab hauv qab muaj qhov dav dav uas zaum ncaj qha rau ntawm cov tsheb ciav hlau thiab cov paib hauv qab, ua rau lawv sib xws nrog cov txheej txheem elastic fastening thiab cov pob zeb ua vaj tse, uas yog cov kev tsim kho niaj hnub no.
Hom kev tsheb ciav hlau no tau hloov pauv cov tsheb ciav hlau qub qub thiab cov khoom sib zog vim nws muab kev ruaj ntseg zoo dua, kev txhim kho yooj yim dua, thiab kev xa khoom zoo dua. Nyob rau hauv txoj kev tsheb ciav hlau loj, metro systems, thiab hnyav- thauj cov tsheb thauj mus los, 60 kg / m class rails sawv cev qhov sib npaug zoo tshaj plaws ntawm lub zog ntawm cov qauv, hnav tsis kam, thiab cov nqi mus ncig.
Piv txwv ntawm Common Heavy Rail Profiles Siv Thoob Ntiaj Teb
| Txuj | Profile | Qhov hnyav (kg / m) | Daim ntawv thov |
|---|---|---|---|
| UIC 860 | UAS 60 | 60.21 | Mainline neeg nrog caij thiab freight |

| wb 2585 | P60 (60kg) | 61.64 | Suav teb chaws railways |
| AREMA | 136 ROJ | 67.41 | North American hnyav freight |
| JIS | 60kg ua | ~60 | Cov kab tsheb ciav hlau hauv Nyij Pooj |
Rau cov haujlwm thoob ntiaj teb,GNEE RAILmuab tag nrho cov saum toj no cov ntaub ntawv thiab tuaj yeem phim ob qho tib si geometry thiab qib steel rau cov kab ke uas twb muaj lawm, kom ntseeg tau tias muaj kev sib raug zoo nrog cov txheej txheem fastening thiab vuam cov qauv.
Puas Muaj Lwm Hom Kev Tsheb Ciav Hlau rau Kev Siv Tshwj Xeeb?
Thaum 60 kg/m tiaj tus- hauv qab txoj kab tsheb ciav hlau tseem ceeb, lwm hom kev tsheb ciav hlau muaj nyob hauv ib puag ncig tshwj xeeb.
- Lub teeb rails, feem ntau yog li ntawm 18 kg / m txog 30 kg / m, yog dav siv nyob rau hauv industrial railways, mines, yards, thiab ib co lub teeb rail transit systems uas qag loads qis thiab installation yooj yuav tsum tau.
| 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 | |
- Crane rails, xws li DIN A-series thiab Suav QU-series rails, yog tsim los nrog cov webs tuab dua thiab siab dua lub taub hau kom tiv taus lub log siab heev thiab lub zog sab nraud los ntawm cov nyiaj siv ua haujlwm cranes hauv cov chaw nres nkoj, steel mills, thiab thawv terminals.
| Crane Rail | qw 70 | 120 | 70 | 120 | 28 | 52.8 |
| qw 80 | 130 | 80 | 130 | 32 | 63.69 | |

| qw 120 | 170 | 120 | 170 | 44 | 118.1 |
- Grooved railsyog cov txheej txheem hauv txoj kev tsheb ciav hlau vim tias qhov zawj tso cai rau cov tsheb thauj mus los hla kev sib tsoo thaum ua kom lub taub hau tsheb ciav hlau ua raws li qib pavement.
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.
