A hlau railyog cov txheej txheem taug qab cov txheej txheem tsim los coj cov log thiab nqa cov khoom hnyav hnyav kom nyab xeeb rau cov kev txhawb nqa pw tsaug zog thiab subgrade, thaum tswj kev sib raug zoo thiab kev ua haujlwm ntawm lub tsheb. Nws lub taub hau, web, thiab ko taw profile tswj khoov thiab hnav.GNEE RAILmuab tag nrho -txoj kev tsheb ciav hlau suav nrog QU70–QU120, DIN536 A55–A120, GB 8–60 kg rails, UIC50–UIC60, JIS 15KG–CR100, AS{12}}–89 kg, BS11:195/AS15, thiab ARE 2. kev kho mob, ua ntej- sib dhos, thiab qhov project{19}}cov lus qhia tshwj xeeb.
Dab tsi yog qhov sib txawv ntawm cov ntsia hlau?
Rail qauv (kev qhia tshwj xeeb) feem ntau yog cais los ntawmQhov hnyav ib ' meter ' (kg / m). Cov qauv sib txawv nyob rau hauv ntau lub teb chaws thiab cheeb tsam, thiab lawv kuj raug faib raws li lub hom phiaj (xws li cov kab tsheb ciav hlau loj, subways, lub teeb rails, crane rails, thiab lwm yam). Cov qauv kev tsheb ciav hlau thiab kev faib tawm yog raws li hauv qab no:
I. Rail qauv raws li Suav National Standards (GB)
Railways hauv Suav teb feem ntau faib cov kev tsheb ciav hlau los ntawm qhov hnyav ib 'meter', nrog rau cov qauv hauv qab no:
1. Rails rau kab zoo tib yam (siv nyob rau hauv lub ntsiab railways, freight railways, thiab lwm yam.)
- 38kg / m: Feem ntau siv nyob rau hauv txoj kev tsheb ciav hlau thaum ntxov, tam sim no maj mam tawm mus, tsuas yog khaws cia hauv qee cov kab, cov kab tshwj xeeb lossis cov kab qub.
- 43kg / m: Ib zaug siv dav hauv nruab nrab thiab qis - kev tsheb ciav hlau ceev, tam sim no feem ntau siv hauv kev tsheb ciav hlau hauv zos, Hoobkas thiab kuv cov kab tshwj xeeb, thiab lwm yam.
- 50kg / m: Ib qho ntawm cov qauv tseem ceeb rau cov kab tseem ceeb tam sim no ntawm txoj kev tsheb ciav hlau zoo tib yam, haum rau cov neeg caij tsheb sib xyaw thiab cov kab thauj khoom, nrog lub zog zoo thiab kav ntev.
- 60kg / m: Cov qauv tseem ceeb rau hnyav - tsheb ciav hlau thiab siab - kev tsheb ciav hlau ceev zoo tib yam (xws li cov kab nrog kev ceev ntawm 160-200km / h), nrog rau cov kabmob muaj zog thiab hnav zoo dua.
- 75kg / m: Siv nyob rau hauv hnyav -haul railways (xws li Daqin Railway) thiab freight mob siab kab, haum rau tsheb ciav hlau nrog loj qag loads (axle load Ntau tshaj los yog sib npaug zos rau 25t), muaj zog zoo heev thiab qaug zog kuj.

2. Cov tsheb ciav hlau tshwj xeeb rau siab - kev tsheb ciav hlau ceev
60kg / m (siab- tsheb ciav hlau ceev): Tuam Tshoj txoj kev siab - kev tsheb ciav hlau ceev (nrog kev ceev ntawm 250-350km / h) feem ntau siv 60kg / m rails. Cov ntaub ntawv feem ntau yog U71MnG, U75V, thiab lwm yam, uas yuav tsum tau flatness siab dua, hnav tsis kam thiab vuam kev ua tau zoo, feem ntau yog seamless kab (ntev rail strips).
Qee qhov tshwj xeeb (xws li hnyav-haul siab- cov kab kev tsheb ciav hlau ceev) yuav siv cov hlua nrog lub zog siab dua ntawm 75kg / m, tab sis lawv daim ntawv thov tsawg dua.
