Cov qib hlau twg yog qhov zoo tshaj plaws rau kev tsim uic54?
UAS 54 rail(tseem hu ua 54E1 rail lossis rail 54E1) yog tsim los siv ua tib zoo xaiv cov qib steel uas ua tau raws li UIC 860 / EN 13674-1 cov qauv. Qib "zoo tshaj" steel tsis yog ib qho kev xaiv ruaj khov. Nws nyob ntawm seb txoj kev tsheb ciav hlau yuav siv li cas, suav nrog kev thauj khoom qag, tsheb thauj mus los, thiab kev cia siab txij nkawm.
uic54 rail specification:
| Hom Rail | Dimensions mm | Qib Steel | Qhov hnyav (Kg / m) | |||
| Rail qhov siab / A | Hauv qab dav / F | Lub taub hau dav / C | Web Thickness/t | |||
| 54E1 (UA 54) | 159 | 140 | 70 | 16 | R200 / R260 / R260Mn / R300HT | 54.77 |
| 60E1 (UA 60) | 172 | 150 | 72 | 16.5 | R200 / R260 / R260Mn / R300HT | 60.21 |
Rau feem ntau txoj kev tsheb ciav hlau, cov qib pom zoo feem ntau yog R260, R300, R350HT, thiab U71Mn. Txhua qib no muaj qhov sib txawv ntawm qhov sib npaug ntawm lub zog, hardness, hnav tsis kam, thiab tus nqi, tso cai rau UIC54 rail profile ua tau zoo nyob rau hauv ntau qhov chaw ua haujlwm. NtawmGNEE RAIL, cov qib no yog tsim los nrog kev tswj dov thiab kev kho cua sov kom ntseeg tau tias kev ua haujlwm ruaj khov thiab ua raws li UIC54 rail specification.
Yuav Ua Li Cas Cov Qib Hlau Ua Haujlwm hauv UIC54 Rail?
Cov qib hauv qab no yog siv dav hauv kev tsim khoomUIC54 rail profile, txhua tus ua haujlwm rau ib qho kev thov tshwj xeeb.
- R260yog qib siv dav tshaj plaws rau cov qauv kev tsheb ciav hlau. Nws muaj kev ntseeg tau lub zog thiab zoo toughness, ua rau nws haum rau cov neeg caij tsheb thiab cov tsheb thauj khoom. Nws kuj yog tus nqi - ua tau zoo, uas ua rau nws zoo tagnrho rau cov haujlwm loj - cov phiaj xwm loj uas tswj kev siv nyiaj txiag tseem ceeb.

- R350 HTyog cov cua sov- kho siab- qib zog. Nws muaj qhov hardness ntau dua, uas txhim kho kev ua haujlwm ntawm kev tsheb ciav hlau lub taub hau thiab dov kev qaug zog. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau hnyav- txoj kev tsheb ciav hlau, siab - cov kab nrawm, thiab cov kab nkhaus uas hnav hnyav dua.

Txhua yam ntawm cov ntaub ntawv no tuaj yeem siv los tsimUAS 54 rail, tab sis lawv cov kev ua tau zoo yuav txawv nyob ntawm kev ua haujlwm.
Yam Qib Steel Koj Yuav Tsum Xaiv rau Koj Qhov Haujlwm?
Xaiv cov qib steel zoo tshaj plaws rauUIC54 rail (54E1 rail)yuav tsum muaj cov khoom sib txuam rau cov kev pabcuam tiag tiag. Rau cov qauv railway kab nrog nruab nrab loads thiab tsheb,R260 los yog U71Mnfeem ntau yog txaus thiab muaj kev tswj tus nqi zoo.
Rau cov kab uas muaj tsheb khiav ntau dua los yog muaj zog hnav,R300muab qhov kev xaiv muaj zog thiab ruaj khov dua yam tsis muaj kev nce nqi loj. Thaum txoj kev tsheb ciav hlau ua haujlwm nyob rau hauv hnyav qag loads, siab ceev, los yog yuav tsum tau ncua kev pab cuam lub neej nrog txo txij nkawm,R350 HTdhau los ua qhov kev xaiv zoo tshaj plaws vim nws cov hardness superior thiab qaug zog kuj.
Qhov tseem ceeb yog kom tsis txhob dhau - specification lossis qis dua - specification. Xaiv cov qib uas siab dhau yuav ua rau tus nqi nce ntxiv, thaum xaiv cov qib qis dua yuav ua rau hnav sai dua thiab cov nqi kho mob ntau dua lub sijhawm.
Dab tsi Ua Qib Hlau "Zoo Tshaj" rau UIC54 Rail?
Ua ntej sib piv cov qhab nia tshwj xeeb, nws yog ib qho tseem ceeb kom nkag siab txog cov qauv siv los ntsuas lawv. Rails raug cuam tshuam rau lub log txuas ntxiv, cuam tshuam kev thauj khoom, thiab kev ntxhov siab cyclic. Yog hais tias cov hlau yog mos heev, lub taub hau rail yuav hnav sai heev. Yog hais tias nws nyuaj heev yam tsis muaj toughness txaus, nws yuav tawg nyob rau hauv dynamic loads.
Cov khoom siv zoo tagnrho raucev 54e1yuav tsum ua kom muaj kev sib npaug ntawmhnav tsis kam thiab qaug zog lub zog, thaum tswj kom txaus ductility kom nqus tau qhov cuam tshuam. Tsis tas li ntawd, cov hlau yuav tsum tsim nyog rau dov rau hauv qhov tseebUIC54 rail qhov ntevtsis muaj qhov tsis xws luag.
Vim hais tias cov kab tsheb ciav hlau sib txawv ua haujlwm nyob rau hauv cov xwm txheej sib txawv, qib "zoo tshaj" yog ib txwm yog ib qho uas haum rau qhov chaw ua haujlwm tiag tiag es tsis yog tsuas yog muaj lub zog siab tshaj plaws.
