Dab tsi yog qhov specification ntawm UIC54 railroad?
CovUAS 54(los yog 54E1) railroad yog ib tug, standardized hnyav -lub luag hauj lwm rail profile.The 54E1 (UIC54) rail qauv tsim raws li European qauv EN 13674-1. Nws yog siv rau kev tsim kho tsheb ciav hlau. Qhov no yog hom T seem rail (pav ca hauv qab rails) nrog 54,77kg hnyav ib 'meter'. Rau tus qauv khiav yog siv 54E1 / UIC54 rail rau nruab nrab thiab hnyav thauj khoom.
UIC54 Rail Specification & Dimensions:
54E1 (UIC54) rail yog tsim raws li European tus qauv EN 13674-1. Nws yog siv rau kev tsim kho tsheb ciav hlau. Qhov no yog T-section rail (flat-bottomed rail) nrog rau qhov hnyav ntawm 54,77kg ib meter.

Chemical Composition thiab Mechanical Properties ntawm UIC54 rail profile:
Kev ua haujlwm ntawm UIC54 rail nyob ntawm nws cov metallurgy. Cov ntsiab lus carbon feem ntau yog li ntawm 0.62% txog 0.80%. Manganese qib nyob ntawm 0.70% thiab 1.20% txhawm rau txhim kho toughness. Cov ntsiab lus no ua kom cov tsheb ciav hlau mus txog qhov tsawg kawg nkaus tensile lub zog ntawm 880 MPa rau R260 qib. Rau R350HT, lub zog siab tshaj 1175 MPa. Cov khoom no tiv thaiv kev qaug zog sab hauv thiab txuas ntxiv kev pabcuam lub neej ntawm kev khiav.

Daim ntawv thov ntawm Rail 54E1:
54e1 rail profile yog ntau yam. Nws yog tus qauv kev xaiv rau lub teb chaws txoj kev tsheb ciav hlau sib txuas thoob plaws Europe, Asia, thiab Africa. Nws tsim txhawb nqa ob qho tib si cov neeg caij tsheb ciav hlau thiab kev thauj khoom thauj. Vim nws qhov sib npaug ntawm qhov hnyav thiab lub zog, nws kuj tau nquag siv nyob rau hauv nroog lub teeb rail systems thiab underground subways. Nws muab kev caij tsheb du thaum tswj kev nyab xeeb siab rau siab - tsheb khiav ceev.
GNEE RAILmuab kev txhim khu kev qha UIC54 (54E1) steel rails rau kev thov kev tsheb ciav hlau. Kev tsim khoom ua raws EN 13674-1 kom ntseeg tau tias zoo ib yam. Cov ntsia hlau muaj peev xwm thauj khoom muaj zog thiab kev ua haujlwm ruaj khov hauv qab 22-25 tonne qag loads. Nrog kev siv pov thawj hauv cov kab sib xyaw ua ke, lawv yog qhov kev xaiv zoo rau ntau qhov haujlwm.
