A hlau railyog ib tug precision- dov steel taug kev tivthaiv uas txhais lub tsheb khiav nto thiab tswj cov kev taw qhia log zoo ib yam nyob rau hauv hnyav thiab rov qab loads. Nws cov kav ntev thiab qhov tseeb ntawm qhov profile yog qhov tseem ceeb rau kev ua haujlwm ntev - kev nyab xeeb.GNEE RAILCov khoom siv ua tiav cov qauv xws li GB lub teeb thiab hnyav rails, UIC50–UIC60, DIN536 crane rails A55–A120, QU70–QU120, JIS rail series, AS1085 profiles, BS11: 1985, thiab AREMA/ASCE seem, nrog rau cov kev pabcuam xws li kev sib koom ua ntej{10.
Koj txhais li cas los ntawm 60 kg rail?
A "60 kg rail" yog hais txog ib qho hnyav- lub luag haujlwm steel rail hnyav kwv yees li 60 kilograms ib 'meter' (kg / m), qhia nws qhov loj, lub zog, thiab muaj peev xwm rau kev thauj khoom siab, siv rau cov kab loj loj, siab - txoj kev ceev, thiab kev siv hnyav xws li cranes, ua raws li cov qauv xws li UIC 60 lossis JIS 60kg.
Cov yam ntxwv tseem ceeb:
- Qhov hnyav:Nyob ib ncig ntawm 60.6 txog 60.8 kg rau txhua meter ntawm nws qhov ntev, nyob ntawm tus qauv tshwj xeeb (JIS, GB, UIC).

- Daim ntawv thov:Qhov zoo tshaj plaws rau txoj kab tsheb ciav hlau loj, siab - cov neeg caij tsheb ceev, hnyav- thauj khoom thauj, subways, thiab cov tshuab thauj khoom.
Dab tsi yog qhov zoo ntawm kev siv 60kg rail?
Qhov zoo ntawm kev siv 60kg kev tsheb ciav hlau suav nrog lub zog zoo dua thiab ruaj khov rau cov khoom hnyav, lub neej kev pab cuam ntev dua nrog kev txo qis, txo tus nqi txij nkawm vim kev thauj khoom zoo dua, txhim kho kev nyab xeeb rau siab - tsheb ciav hlau ceev, thiab tus nqi -kev ua tau zoo rau hnyav- txoj hauv kev loj, ua rau nws txoj kev xaiv tseem ceeb rau kev tsheb ciav hlau niaj hnub xav tau kev ua haujlwm siab.
Cov txiaj ntsig tseem ceeb:
** Siab Load Capacity:**Engineered los lis axle loads tshaj 30 tons, zoo tagnrho rau hnyav freight thiab siab - tsheb ciav hlau ceev.
** Txhim khu kev ruaj ntseg: **Qhov loj dua modulus resists dabtsi yog khoov thiab deformation, muab superior ntsug thiab lateral khiav stability.
** Lub neej ua haujlwm ntev:**Lub log zoo dua qhov kev faib tawm txo qis kev sib cuag thiab hnav, ncua kev tsheb ciav hlau lub neej thiab txiav cov nqi hloov pauv.
** Txo Kev Kho Mob: **Kev hnav qis dua thiab txhim kho kev thauj mus los rau ballast txhais tau tias tsis tshua muaj kev saib xyuas thiab kev tshuaj xyuas ntev dua.
** Txhim kho kev ua tau zoo:**Txhawb kev tsheb ciav hlau siab dua (piv txwv li, mus txog 160 km / h) thiab kev khiav tsheb ceev nrog kev nyab xeeb dua thiab kev caij tsheb zoo dua.
** Nqis -Zoo:**Muab kev ua haujlwm siab thiab ua haujlwm ntev, muab cov txiaj ntsig kev lag luam zoo dua rau kev xav tau txoj hauv kev xws li mainlines thiab hnyav -txoj kev taug kev.
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.
