Dab tsi hlau feem ntau siv rau kev tsheb ciav hlau?
Jan 19, 2026
Hlau rail, peb kuj hu ua txoj kev tsheb ciav hlau, nws yog ib qho tseem ceeb rau steel railing system. Raws li ib feem ntawm txoj kev tsheb ciav hlau, steel rail coj lub tsheb ciav hlau mus rau pem hauv ntej thiab dais lub siab loj. Meanwhile, steel rails qhia lub siab mus rau railway sleepers. Yog li steel rails ua lub luag haujlwm tseem ceeb hauv txoj kev tsheb ciav hlau thiab qhov zoo ntawm cov hlua hlau yog qhov tseem ceeb heev.
Tsis tas li ntawd, steel rails muaj lwm txoj haujlwm tseem ceeb. Cov hlau ntsia hlau muab qhov chaw du thiab tsis muaj zog rau cov tsheb uas ua kom muaj kev nyab xeeb.
Dab tsi hlau feem ntau siv rau kev tsheb ciav hlau?
Hlau rails, cov khoom tseem ceeb ntawm txoj kev tsheb ciav hlau, feem ntau yog ua los ntawm siab -lub zog carbon-manganese steel. Cov khoom no yog xaiv rau nws zoo heev ua ke ntawm hardness, hnav tsis kam, thiab toughness, tso cai rau rails mus rau lub enormous siab thiab dynamic loads los ntawm tsheb ciav hlau. Cov qhab nia raug suav nrogU71Mn, U75V, 55Q, Q235,thiabR350 HT, uas yog dav siv nyob rau hauv industrial, mining, thiab mainline railway daim ntaub ntawv.
| Qib Steel | Cov pa roj carbon (%) | Manganese (%) | Silicon (%) | Hom kev siv |
|---|---|---|---|---|
| ua 71mn | 0.65–0.76 | 1.10–1.40 | 0.15–0.35 | Mainline heavy rail, siab -speed rail |
| U75V | 0.71–0.80 | 0.70–1.05 | 0.50–0.80 | High - tsheb ciav hlau ceev, hnyav - daim ntawv thov |
| 55Q | 0.50–0.60 | 0.60–0.90 | 0.15–0.35 | Lub teeb rail, industrial kab |
| Q235 | 0.12–0.20 | 0.30–0.70 | Tsawg dua los yog sib npaug li 0.30 | Mining rail, lub teeb industrial kab |
| R350 HT | 0.70–0.82 | 0.60–1.25 | 0.13–0.60 | Siab - nrawm European mainlines |
Hlau yog siv rau lwm yam hlau xws li hlau los yog txhuas vim nws muab ib tug zoo meej tshuav nyiaj li cas ntawm lub zog, durability, thiab kuj rau hnav thiab qaug zog. Tsis zoo li cov hlau ntshiab, steel rails tuaj yeem tiv taus cov khoom hnyav dua los ntawm kev siab - ceev lossis hnyav thauj khoom thauj yam tsis muaj deforming. Cov pa roj carbon-manganese steels zoo li U71Mn yog cov cua sov- kho kom zoo dua qub, ua rau lub neej ua haujlwm ntev thiab kev saib xyuas tsawg. Tsis tas li ntawd, cov khoom siv hlau tsis sib xws ua kom lub ntsej muag du, uas txo cov log hnav thiab txhim kho kev nyab xeeb.
Yuav Ua Li Cas Steel Rails Tsim?
Rails yog tsim los ntawmkub- dov txheej txheem, qhov twg carbon-manganese steel yog rhuab thiab zoo li tus I-zoo li tus ntoo khaub lig seem, muaj xws li lub taub hau rail, web, thiab ko taw. Qhov kev tsim no ua kom muaj qhov siab tshaj plaws khoov tsis kam thiab thauj khoom faib. Qee qhov kev tsheb ciav hlau tau dhau musKev kho cua sovtxhawm rau txhim kho kev hnav tsis kam, tshwj xeeb tshaj yog rau siab - nrawm lossis hnyav- txoj haujlwm khiav. GNEE RAIL tsim ob qho tib si qauv thiab kev cai rails kom tau raws li ntau yam thoob ntiaj teb cov qauv, suav nrogGB, UIC, JIS, AREMA, thiab DIN, ua kom muaj kev sib raug zoo rau lub ntiaj teb kev tsheb ciav hlau.
| Txuj | Hom Rail | Qhov hnyav (kg / m) | Ntev (m) | Khoom siv |
|---|---|---|---|---|
| GB11264-89 | Lub teeb Rail 22KG | 22 | 6–12 | Q235, 55Q |
| UIC860 | UAS 60 | 60.21 | 12–25 | R260, R350HT |
| JIS E1101 | 22 KG | 22.3 | 9–12 | JIS E Steel |
| AREMA | 60 RE | 60 | 12–25 | SS, HH, LA, IH |
| TIAB SA 536 | A100 | 100 | 10–12 | 900A |
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.
