A hlau railyog ib tug hardened steel kev taw qhia qauv uas txhais cov khiav geometry thiab absorbs log cuam tshuam quab yuam, ua kom muaj zog thiab rov ua lub tsheb txav raws txoj kev ruaj khov. Nws tus ntoo khaub lig-sectional daim ntawv txiav txim siab dabtsi yog khoov thiab tiv tauj tus cwj pwm.GNEE RAILxa cov tsheb ciav hlau hla GB, UIC, DIN536, JIS, AS1085, BS11, thiab AREMA / ASCE cov qauv, suav nrog crane rail series QU thiab DIN A- hom, thiab muaj cov kev pabcuam xws li kev tsheb ciav hlau vuam kev daws teeb meem, kev sib koom ua ke, thiab cov txheej txheem kev teeb tsa.
Dab tsi yog qhov txawv ntawm GB Rail thiab BS Rail?
Qhov sib txawv ntawm GB (Suav) rails thiab BS (British Standard) rails nyob rau hauv lawv cov qauv, qhov ntev, hnyav chav kawm, qib steel, thiab cov kev siv, uas qhia txog cov qauv engineering ntawm Tuam Tshoj thiab lub tebchaws United Kingdom. Nov yog qhov kev sib piv ntxaws:
1. Cov Txheej Txheem thiab Cov Txheej Txheem Txheej Txheem
- GB Rails:Kev tswj hwm los ntawm Suav cov qauv hauv tebchaws (GB / T series), piv txwv li, GB / T 11264-2012 rau cov tsheb ciav hlau lossis GB / T 8162-2018 rau cov tsheb ciav hlau hnyav. Cov txheej txheem no txhais qhov ntev, qib steel, cov khoom siv kho tshuab, thiab kev tsim cov khoom ua kom haum rau kev ua haujlwm ntawm Tuam Tshoj txoj kev tsheb ciav hlau, suav nrog lub hauv paus, kev lag luam, thiab kev siv tsuas.
- BS Rails:Tsim los ntawm British Standards (BS 11: 1985 rau kev tsheb nqaj hlau), uas qhia txog kev tsheb nqaj hlau, qhov hnyav, qhov ntev, thiab kev ua siab ntev rau cov kab hnyav, qauv, thiab cov kab tsheb ciav hlau. BS rails muaj keeb kwm tau siv nyob rau hauv UK thiab yav dhau los lub tebchaws Commonwealth thiab yog tsim los kom phim British taug qab engineering xyaum.

Dab tsi yog cov khoom ntawm rail?
Rails feem ntau yog tsim los ntawm siab -lub zog, kub- cov pa roj carbon steel, tshwj xeeb yog tsim los tiv taus hnyav hnyav, khoov, thiab hnyav hnyav. Cov qib steel muaj xws li R260 thiab R350HT (kub-kho). Lawv muaj cov ntsiab lus siab carbon (0.6% - 0.8%) thiab manganese kom nce hardness.
