A hlau railyog ib tus tswv cuab txuas ntxiv uas ua haujlwm raws li ob qho kev taw qhia thiab thauj khoom -cov kabmob, ua kom muaj kev sib haum xeeb, nyab xeeb, thiab txhim khu kev qha ntawm cov tsheb ntawm kev tsheb ciav hlau lossis kev lag luam. Nws qhov profile, cov khoom siv, thiab kev kho deg ncaj qha cuam tshuam rau kev hnav, qaug zog tiv thaiv, thiab kev sib haum xeeb.GNEE RAILmuaj ntau yam kev tsheb ciav hlau thoob ntiaj teb, suav nrog GB lub teeb thiab hnyav, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS1085 31–89 kg, BS11: 1985, thiab AREMA/15 kev tiv thaiv, 2 thiab ASCE; installation kev pab tswv yim.
Dab tsi yog cov haujlwm ntawm cov tsheb ciav hlau thiab cov pw tsaug zog?
Hauv txoj kev tsheb ciav hlau, cov tsheb ciav hlau thiab cov neeg pw tsaug zog (kev sib txuas) ua haujlwm ua ke raws li cov qauv thiab kev ua haujlwm, txhua qhov ua tau zoo tab sis muaj kev cuam tshuam cov luag haujlwm uas ua kom muaj kev nyab xeeb ntawm tsheb ciav hlau, kev thauj mus los, thiab ntev - lub sijhawm taug kev ruaj ntseg. Lawv cov dej num tuaj yeem nkag siab meej los ntawm ob qho tib si kev xav thiab kev ua haujlwm.
Lub luag haujlwm ntawm Rails:
- Rails yog qhov sib txuas ncaj qha ntawm lub tsheb ciav hlau thiab txoj kev khiav. Lawv lub luag haujlwm tseem ceeb yog txhawb nqa thiab faib cov log tsheb los ntawm cov khoom dov mus rau cov neeg pw tsaug zog thiab tom qab ntawd mus rau ballast lossis slab foundation. Vim tias cov tsheb ciav hlau niaj hnub ua kom muaj zog zoo li qub thiab muaj zog, cov tsheb ciav hlau yuav tsum tiv thaiv kev nyuaj siab, kev sib cuag, kev cuam tshuam, thiab qaug zog, uas yog vim li cas siab - lub zog pearlitic steels xws liU71Mn, R260, UAthiabR350 HTtau siv dav.

- Rails tseem coj lub log tsheb ciav hlau thiab tswj qhov ntsuas qhov tseeb, kom ntseeg tau tias cov tsheb nyob hauv kev nyab xeeb, txawm tias muaj kev kub ceev lossis dhau ntawm qhov nkhaus. Lub taub hau kev tsheb ciav hlau thiab kev sib dhos yog qhov tseem ceeb rau kev ruaj ntseg ntawm lub tsheb, txo lub log hnav, thiab tiv thaiv derailment. Tsis tas li ntawd, rails muab ib tug du thiab nruam khiav nto, uas minimizes dov kuj, kev co, thiab suab nrov, kev txhim kho lub zog efficiency thiab cov neeg nrog caij.
- Hauv ntau txoj kev tsheb ciav hlau, cov tsheb ciav hlau txuas ntxiv ua ib feem ntawm cov hluav taws xob rov qab los rau kev taw qhia thiab kev sib tw, ua kom muaj hluav taws xob zoo txuas ntxiv thiab kev tiv thaiv corrosion tseem ceeb rau kev nyab xeeb kev tsheb ciav hlau thiab kev ntseeg tau ntawm lub cev.
Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv hlau sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.

Lub luag haujlwm ntawm Sleepers (Ties):
- Cov neeg pw tsaug zog ua raws li cov tswvcuab txhawb nqa hauv qab ntawm txoj hlua. Lawv lub luag haujlwm tseem ceeb yog tuav cov ntsia hlau kom ruaj khov rau hauv txoj haujlwm thiab tuav txoj kev ntsuas qhov tseeb thiab kev sib haum xeeb hauv qab lub tsheb ciav hlau rov qab. Los ntawm kev kho ob txoj hlua ntawm qhov chaw ruaj khov, cov neeg pw tsaug zog tiv thaiv qhov ntsuas qhov dav thiab qhov txav mus rau sab nraud, uas yog qhov ua rau muaj kev tsis ruaj khov.
- Cov neeg pw tsaug zog kuj tseem faib cov tsheb thauj mus los hla thaj tsam dav dua ntawm ballast lossis pob zeb hauv paus, txo qhov siab ntawm subgrade thiab tiv thaiv kev sib haum xeeb ntau dhau. Qhov kev faib khoom thauj khoom no yog qhov tseem ceeb rau kev tswj cov kab deformation thiab tuav ntev - lub sij hawm geometry. Tsis tas li ntawd, cov neeg pw tsaug zog muab lub hauv paus ruaj khov rau txoj kev tsheb ciav hlau, nrog rau cov hlua khi, cov phaj hauv qab, thiab cov ntaub qhwv, uas tswj cov kev sib tw ntsug, nqus kev co, thiab txo cov kev cuam tshuam ntawm kev xa mus rau cov qauv kev khiav.
Lub hauv paus ntsiab lus ua haujlwm ntawm steel rail yog dab tsi?
Lub hauv paus ntsiab lus ntawm kev ua haujlwm steel yog ua raws li qhov muaj zog, du, qib girder coj lub log thiab hloov cov tsheb ciav hlau loj heev rau cov neeg pw tsaug zog, ballast, thiab tsim, tso siab rau steel - ntawm - steel kev sib txhuam (adhesion) rau traction, braking, thiab kev taw qhia, thaum lub sij hawm tiv thaiv ntsug 2 bending thiab kev txhawb nqa ntawm nws kev nyab xeeb, kev mus ncig zoo. Nws lub luag haujlwm tseem ceeb yog kev thauj mus los, kev taw qhia lub log (ntu & sab), thiab muab qhov qis -kev sib txhuam nto, ua haujlwm los ntawm siab - lub zog steel thiab cov qauv tsim.
- Load Transfer: Rails ua raws li cov kab hluav taws xob txuas ntxiv, faib cov tsheb thauj khoom hnyav los ntawm lub tsheb ciav hlau mus rau cov neeg pw tsaug zog (kev sib raug zoo) hauv qab, uas tom qab ntawd kis cov khoom thauj mus rau ballast (pob zeb crushed) thiab thaum kawg hauv av (tsim).
- Kev taw qhia & Smoothness: Txoj kev tsheb ciav hlau qhov profile muab qhov sib luag, txuas ntxiv, thiab qhov tseeb gauged nto rau steel log rau yob, tiv thaiv kev txav mus los (flange taw qhia) thiab ua kom muaj kev caij tsheb zoo.
- Adhesion Traction: Qhov tseem ceeb kev sib txhuam (adhesion) ntawm lub log steel thiab steel rail muab lub zog rau acceleration (traction), braking, thiab centering lub tsheb ciav hlau, tsim lub hauv paus ntawm feem ntau railways.
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.
