Lub steel rail yog kub -rolled steel bar, zoo li tus asymmetric I-beam, uas tsim cov ntsiab lus ntawm railway lem, coj lub tsheb ciav hlau log, coj lub siab loj, thiab muab ib tug du, nruam nto rau thauj, thaum tseem ua hauj lwm raws li ib tug hluav taws xob conductor nyob rau hauv electrified kab, yuav tsum tau muaj zog muaj zog, hnav tsis kam, thiab kev nyab xeeb.
rails hnyav npaum li cas?
Rail hnyav sib txawv, feem ntau ntsuas hauv phaus ib yard (lb / yd) nyob rau hauv North America los yog kilograms ib meter (kg / m) nyob rau hauv cov teb chaws Europe, xws li ib tug sib dua li 60 lb / yd (~ 30 kg / m) rau industrial siv txog hnyav - lub luag hauj lwm rails xws li 136 lb / yd / high speed (~ 68 lb / yd) hnyav- cov kab tsheb, nrog rau qhov hnyav hnyav yog 115-141 lb/yd (57-70 kg/m) lossis 60 kg/m rau cov tshuab niaj hnub.
Common Weight ranges:
Lub teeb/Industrial: 60-90 lb/yd (kwv yees . 30-45 kg/m).
Standard Mainline: 115-141 lb/yd (kwv yees . 57-70 kg/m).
Siab -Speed/Havy-Haul: 60 kg/m (121 lb/yd) los yog hnyav dua, xws li 70 kg/m (140 lb/yd).

Yuav ua li cas xaiv txoj cai steel rail hom?
Xaiv txoj kev tsheb ciav hlau yuav tsum sib piv cov tsheb ciav hlau qhov hnyav, lub zog, thiab cov khoom siv rau koj cov kev xav tau tshwj xeeb, feem ntau txiav txim siab los ntawmload (axle hnyav), ceev, tsheb ntim, thiab ib puag ncig, nrog rau ntev - cov nqi thiab kev saib xyuas. Lub cev hnyav dua, muaj zog dua (xws li 60kg / m +) haum hnyav -haul / siab- cov kab nrawm, thaum lub tsheb sib dua (30kg / m lossis tsawg dua) yog kev lag luam rau lub Hoobkas sab hauv lossis qis - siv ceev. Nco ntsoov xyuas kev ua raws li cov qauv kev lag luam (UIC, AREMA, thiab lwm yam) thiab xav txog lub taub hau - cov kev xaiv nyuaj rau kev siv tau ntev.
- Ntsuas koj qhov project xav tau: qag loads, ceev, tsheb zaus, ib puag ncig.
- Kev sab laj cov qauv: Sib piv cov kev xav tau rau hom kev tsheb ciav hlau (xws li GB60, ASCE 40).
- Xav txog tus nqi ntawm lub neej: Sib npaug ntawm tus nqi them ua ntej nrog ntev - tu thiab kav ntev.
NtawmGNEE RAIL, peb tshwj xeeb hauv kev muab ntau yam ntawm kev tsheb ciav hlau, suav nrog cov tsheb ciav hlau hnyav, tsheb ciav hlau, tsheb ciav hlau crane thiab tsheb ciav hlau fastening, nrog rau kev sib tw siab -kev ua haujlwm tsheb ciav hlau clips thiab kev daws teeb meem.
