Ahlau railyog ib qho kev qhia txog kev siv tshuab uas hloov lub log tig mus rau hauv kev tswj cov kab khiav mus los, kom ntseeg tau tias lub tsheb coj tus cwj pwm txawm tias nyob rau hauv qhov hnyav thiab siab - ua haujlwm ntau zaus. Nws cov tawv tawv thiab sab hauv toughness yog optimized los tiv thaiv kev hnav sai thiab sab hauv tawg, uas yog hom tsis ua hauj lwm nyob rau hauv overloaded los yog tsis zoo xaiv rail seem.
GNEE RAILmuaj steel rails npog railway, crane, thiab industrial thauj daim ntaub ntawv nyob rau hauv tag nrho cov thoob ntiaj teb cov qauv, thiab txhawb cov neeg muas zaub nrog steel qib xaiv, hardness tswj kev xaiv, ultrasonic kuaj, thiab kev sib koom tes ntawm fishplates, bolts, clips, thiab baseplates.
railways hu ua dab tsi?
Kev tsheb ciav hlau feem ntau hu uatxoj kev tsheb ciav hlau, txoj kev tsheb ciav hlau, los yogyooj yim taug qab, tab sis nyob rau hauv technical thiab engineering cov ntsiab lus lawv tau raug xa mus raws li txoj kev tsheb ciav hlau mus tas li lossis txoj kev tsheb ciav hlau, uas qhia meej tias txoj kev taug kev yog ib qho kev txhim kho ruaj khov uas tsim los ntev - kev pabcuam es tsis yog txoj hauv kev ib ntus.
Los ntawm cov qauv tsim qauv, txoj kev taug kev tau piav qhia raws li cov qauv kev tsheb ciav hlau, muaj ntau yam sib xyaw ua ke: steel rails, rail fastenings, sleepers (tseem hu ua ties), ballast lossis slab, thiab subgrade. Nyob rau hauv cov qauv thiab cov ntaub ntawv technical, lo lus tsheb ciav hlau tsuas yog hais txog cov hlau khiav ntawm qhov chaw, thaum lub tsheb ciav hlau lossis cov kab ke yog hais txog kev sib dhos ua tiav uas txhawb nqa thiab coj lub tsheb ciav hlau.
GNEE RAILtxhawb nqa ob txoj kev tsheb ciav hlau thiab kev lag luam kev lag luam los ntawm kev muab cov kev daws teeb meem kev tsheb ciav hlau, suav nrog cov tsheb ciav hlau (8-30 kg / m), hnyav rails (38-60 kg / m), UIC50 / 54 / 60, DIN 536 crane rails,QU crane rails, thiab matched fastening systems nrog installation thiab kev txhawb nqa.

Lub luag haujlwm ntawm steel rails yog dab tsi?
Steel rails ua lub hauv paus tseem ceeb ntawm txoj kev tsheb ciav hlau, ua haujlwm feem ntau los muab qhov nruam, du, thiab nruj rau lub tsheb ciav hlau log. Lawv coj lub log raws txoj hauv kev, kev txhawb nqa thiab faib cov khoom loj ntsug thiab sab nraud rau cov neeg pw tsaug zog / ballast, thiab ua cov khoom siv hluav taws xob rau cov teeb liab.
- Kev taw qhia thiab kev txhawb nqa:Rails xyuas kom lub tsheb ciav hlau log nyob ntawm txoj kev, tiv thaiv kev derailments thaum muab qhov qis -tsis kam, du, thiab ruaj khov rau kev txav mus los.
- Load Distribution:Lawv tiv taus lub siab tseem ceeb, suav nrog kev thauj khoom ntsug, sab nraud, thiab lub zog centrifugal los ntawm kev tig, nres, lossis kev tsheb ciav hlau nrawm, hloov cov zog no mus rau cov pw tsaug zog thiab ballast.
- Kev Nyab Xeeb thiab Tswj:Rails ua hauj lwm raws li lub orbital Circuit Court rau tsis siv neeg signaling systems nyob rau hauv electrified railways, tseem ceeb heev rau nrhiav tau lub tsheb ciav hlau qhov chaw.
- Structure Integrity:Tsim los nrog siab -lub zog, hnav- tiv taus, thiab siab - qaug zog- lub zog hlau los tuav cov tsheb thauj khoom hnyav thaum tuav cov geometric stability (gauge).
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.
