A hlau railyog ib qho kev thauj khoom -cov kabmob thiab cov lus qhia uas sib xyaw ua ke ntawm cov qauv muaj zog, hnav tsis kam, thiab cov duab kos duab meej, ua kom lub tsheb muaj kev nyab xeeb thiab du ua haujlwm raws li kev rov ua haujlwm dynamic thiab zoo li qub. Nws lub taub hau, lub vev xaib, thiab ko taw qhov ntev yog tsim los ua kom zoo dua kev faib tawm kev ntxhov siab.GNEE RAILmuaj cov kev tsheb ciav hlau hla txhua tus qauv, suav nrog lub teeb thiab hnyav GB rails, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS1085 31–89 kg, BS11: 1985, thiab AREMA/ASCE ntxiv fabrication 25–100. ua ntej- koom ua ke, thiab ntawm - kev txhawb nqa kev kawm.
Lub luag haujlwm ntawm steel rail yog dab tsi?
Kev taw qhia:Rails muab ib tug meej, nruam nto uas coj tsheb ciav hlau log nyob rau hauv yuav tsum tau kev taw qhia.
Load Bearing:Lawv dais qhov hnyav hnyav thiab cuam tshuam cov tsheb ciav hlau, suav nrog, nrawm, nres, thiab tig lub zog.
Load Distribution:Rails faib lub siab los ntawm lub log mus rau cov pw tsaug zog thiab ballast hauv qab no, txo cov kev ntxhov siab ntawm lub hauv paus.
Smooth Running Surface:Lawv ua kom muaj kev sib tw, qis - kev sib txhuam rau cov tsheb ciav hlau, uas yog qhov tseem ceeb rau kev txav mus los thiab kev nplij siab ntawm cov neeg caij tsheb.
Kev Siv Hluav Taws Xob:Hauv cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob, cov ntsia hlau yog cov khoom siv hluav taws xob rau kev taw qhia thiab taug qab cov kab hluav taws xob hauv hluav taws xob txhawm rau txheeb xyuas cov haujlwm ntawm lub tsheb ciav hlau.
Dab tsi yog hom kev tsheb ciav hlau sib txawv?
Txoj kev tsheb ciav hlau feem ntau yog cais los ntawm lawv tus ntoo khaub lig-sectional profile, nrog lub tiaj tus-Kab hauv qab (Vignoles) kev tsheb ciav hlau feem ntau (kwv yees . 90%) siv) vim nws qhov ruaj khov thiab yooj yim ntawm kev teeb tsa ncaj qha rau cov neeg pw tsaug zog. Lwm hom muaj xws li Bull-Lub Taub Hau, Ob Chav -Lub Taub Hau, Grooved, thiab tshwj xeeb rails rau cov kev siv tshwj xeeb xws li, tus neeg tsav tsheb.
Yam tseem ceeb ntawm Railway Rails
- Pav ca-Bottomed Rail (Vignoles):Cov txheej txheem niaj hnub, muaj lub hauv paus tiaj tus uas zaum ncaj qha rau ntawm cov pw tsaug zog lossis cov ntaub qhwv, txo qhov xav tau ntawm cov rooj zaum.
- Bull-Head Rail:Nta lub taub hau tuab thiab sib dua; keeb kwm muaj nyob rau hauv UK, feem ntau siv tam sim no nyob rau hauv cov ntsiab lus, kev hla, thiab cov cheeb tsam uas yuav tsum tau muaj zog durability.
- Ob chav -Head Rail:Symmetrical sab saum toj thiab hauv qab, Ameslikas tsim los tso cai rau thim rov qab txoj kev tsheb ciav hlau thaum sab saum toj hnav, tab sis qhov no ua pov thawj tsis zoo vim lub rooj zaum puas ntawm lub taub hau.
- Grooved Rail (Girder Rail):Siv feem ntau hauv tramways lossis txoj kev -khiav qhov xwm txheej uas cov tsheb ciav hlau tau kos rau hauv txoj kev pavement, uas muaj qhov sib txawv ntawm flange rau lub log flanges.

Kev faib tawm los ntawm cov qauv thiab qhov hnyav
Rails kuj tau categorized los ntawm qhov hnyav (kg ib meter lossis lbs ib yard) thiab cov txheej txheem txheem:
- UIC Standards:Feem ntau siv thoob ntiaj teb cov qauv, xws li UIC54 thiab UIC60 (siv rau siab -ceev / hnyav-haul).
