CovUAS 60 rail, peb kuj hu nws 60E1, yog ib tug dav siv railway rail profile tsim los ntawm European International Railway Union (UIC). Nws yog ib qho hnyav - txoj haujlwm tsheb ciav hlau uas hnyav 60.21 kg ib 'meter', tsim nrog "H" -zoo li tus ntoo khaub lig seem ntsuas 172 hli qhov siab thiab 150 hli puag dav.

Dab tsi steel qib yog qhov zoo tshaj plaws uic60 rail khoom?
60E1 (los yog UIC 60) rails yog siab -zoo, carbon-manganese steel rails ua raws li European Standard EN 13674-1. Cov qib steel feem ntau rau cov tsheb ciav hlau no suav nrogR260 (standard hardness),R320 Cr, thiabR350 HT(kub-kho). Cov ntaub ntawv no muab lub zog siab, ua haujlwm ntev, thiab hnav tsis kam, feem ntau nrog qhov nyuaj ntawm 260-390 HB.
Tus Qauv Xaiv: R260 Steel Qib
Rau feem coob ntawm cov phiaj xwm kev tsheb ciav hlau loj, R260 suav tias yog tus qauv kev lag luam thiab feem ntau yog qhov "zoo tshaj" sib npaug ntawm kev ua haujlwm thiab tus nqi. Qib no yog cov hlau pearlitic nrog qhov nyuaj ntawm 260 txog 300 HBW (Brinell Hardness). Nws muaj cov weldability zoo heev thiab txaus hnav tsis kam rau cov kab ncaj nraim.

Vim tias nws yog peb cov qib uas nquag tsim tawm, peb lub chaw tswj hwm siab - ntim efficiency rau R260, ua rau nws yog qhov kev xaiv pheej yig tshaj plaws rau kev sib txuas hauv lub teb chaws thiab cov kab tsheb thauj khoom uas muaj qhov nkhaus hnyav tsis yog qhov kev txhawj xeeb tseem ceeb.
Qhov Kev Xaiv Tshwj Xeeb: R350HT Thaum tshav kub kub-Tshuaj Rail
Thaum cov neeg siv khoom nug txog cov khoom "zoo tshaj" nyob rau hauv cov nqe lus ntawm lub neej ntev thiab durability, cov lus teb yog R350HT. Qib no tau dhau los ua cov txheej txheem tshwj xeeb "Head Hardening" (HT) hauv peb qhov chaw. Los ntawm kev tswj cov cua txias ntawm lub taub hau tsheb ciav hlau tom qab dov, peb ua tiav cov qauv zoo pearlitic nrog lub hardness ntawm 350 txog 390 HBW.

Cov khoom no yog tsim los tshwj xeeb rau siab - ib puag ncig kev nyuaj siab. Nws yog qhov kev xaiv zoo tshaj plaws rau kev nkhaus ntse, hnyav-haul mining lem, thiab siab -frequency metropolitan transit systems. Thaum tus nqi pib ib tuj siab dua, R350HT txo qis "Tag nrho Tus Nqi ntawm Cov Tswv Cuab." Nws tiv taus kev sib cuag nrog kev qaug zog thiab sab hnav zoo dua li cov qauv qib, txhais tau tias cov lem yuav tsum tsis tshua muaj kev saib xyuas thiab hloov.
Yuav ua li cas xaiv txoj cai Rail 60e1 khoom?
Kev xaiv txoj cai 60E1 (UIC60) cov khoom siv tsheb ciav hlau yuav tsum sib piv cov qib steel thiab hardness rau kev ua haujlwm load, ceev, thiab ib puag ncig, ua raws li EN 13674-1 cov qauv. Siv R260 rau txoj kab dav dav / neeg caij tsheb thiab R350HT / R350LHT (lub taub hau- tawv) rau hnyav-haul, nruj nkhaus, lossis qhov hnyav hnyav, feem ntau ua kom lub zog tensile ntau ntawm 680 txog 1175 MPa.
Kev txiav txim siab tseem ceeb rau xaiv 60E1 Rail Khoom:
Load thiab ceev (qib xaiv):
- R260: Standard carbon steel (kwv yees . 260-300 HB) rau siab- ceev thiab dav siv hauv mainline, muab zoo toughness thiab hnav tsis kam.
- R350HT / R350LHT: Head-hardened (heat-treated) steel (>350 HB) tsim los rau hnyav - thauj khoom thauj, siab - cov kab tonnage, thiab nkhaus nkhaus, muab lub neej qaug zog zoo dua.
Environmental Factors (Durability):
- Rau cov ntug dej hiav txwv lossis thaj chaw muaj kev lag luam, xaiv cov tsheb ciav hlau nrog cov ntsiab lus sulfur thiab phosphorus qis (<0.05% S, <0.03% P) to prevent brittleness.
- Copper-muaj cov alloys (0.2–0.4% Cu) raug pom zoo los tsim kom muaj kev tiv thaiv patina hauv ib puag ncig corrosive.
