Keeb kwm: Ib Profile, Ob Lub Npe Systems
UIC60 thiab 60E1 yog xa mus rau tib txoj kev tsheb ciav hlau: UIC60 yog lub npe siv los ntawm International Union of Railways, thiab 60E1 yog qhov kev xaiv raws li European tus qauv EN 13674-1, uas suav nrog railway rails ntawm 46 kg / m thiab siab dua. Qhov profile yog lub tiaj tus - hauv qab tsheb ciav hlau nrog lub npe loj ntawm 60.21 kg / m, tsim los rau siab - cov neeg caij tsheb ceev, cov tsheb thauj khoom hnyav thiab txoj kev tsheb ciav hlau sib xyaw. Vim hais tias qhov profile geometry yog standardized, rails los ntawm txawv mills yog interchangeable rau ib leeg thiab nrog rau tus qauv fastening, fishplate thiab expansion sib koom ua ke ua rau 60E1 seem.

Steel Qib thiab Mechanical Properties
EN 13674-1 txhais cov qib pearlitic steel xaiv los ntawm hardness thiab hnav tsis kam. Cov kev qhia dav tshaj plaws yog R260 rau cov qauv kev pabcuam thiab R350HT rau cua sov- kho siab- kev pabcuam hnav, nrog R200 thiab R260Mn muaj rau cov ntawv thov qis dua thiab manganese-alloyed.
| Qib | Tensile zog MPa | Elongation min | Hardness HBW | C % | Si% | Mn% | S max % | P max % | H ppm max | Aw ppm max |
|---|---|---|---|---|---|---|---|---|---|---|
| R200 | Tsawg kawg yog 680 | 14% | 200-240 | 0.40-0.60 | 0.15-0.58 | 0.70-1.20 | 0.025 | 0.035 | 3 | 20 |
| R260 | Tsawg kawg yog 880 | 10% | 260-300 | 0.62-0.80 | 0.15-0.58 | 0.70-1.20 | 0.025 | 0.025 | 2.5 | 20 |
| R260Mn | Tsawg kawg yog 880 | 10% | 260-300 | 0.55-0.75 | 0.15-0.60 | 1.30-1.70 | 0.025 | 0.035 | 2.5 | 20 |
| R350 HT | Tsawg kawg yog 1175 | 9% | 350-390 | 0.72-0.80 | 0.15-0.58 | 0.70-1.20 | 0.025 | 0.020 | 2.5 | 20 |
R350HT yog cua sov kho los ntawm lub taub hau kom ncav cuag nws cov hardness siab dua thiab tensile lub zog, uas kwv yees ua ob npaug rau lub neej hnav ntawm cov nkhaus nkhaus piv nrog R260, ntawm tus nqi ntau dua. R260Mn siv cov ntsiab lus manganese ntxiv los txhim kho los ntawm - hardness thiab hnav tus cwj pwm yam tsis muaj kev kho cua sov.
Tolerances thiab Kev Tswj Xyuas Zoo
60E1 rails raug xa mus rau qhov profile nruj thiab kev ua siab ntev ntev. Profile kam rau ua chav kawm X tswj lub taub hau dav ntawm 74.3 hli, qhov siab ntawm 172 hli thiab lub hauv paus dav ntawm 150 hli nyob rau hauv ntxiv los yog rho tawm 0.5 hli, uas guarantees qhov chaw zaum ntawm rail clips thiab baseplates. Straightness class A txwv txoj kev sib txawv ntawm txoj kab ntsug thiab sab nraud kom txoj kev tsheb ciav hlau khiav qhov tseeb ntawm kev kub ceev. Cov qauv ntev yog feem ntau 12 mus rau 25 m, lub qhov taub ntses phaj yog drilled mus rau ib txoj kab uas hla ntawm 33 hli nrog txoj hauj lwm tolerances ntawm lub vev xaib, thiab qhov saum npoo yog descaled nyob rau hauv siab siab thaum lub sij hawm tsim khoom. Kev tswj xyuas zoo suav nrog kev txheeb xyuas cov tshuaj muaj pes tsawg leeg nrog lub tshuab nqus tsev degassing thiab theem nrab refining kom tshem tawm impurities, kev ntsuam xyuas ntawm lub zog tensile, hardness thiab cuam tshuam tsis kam, thiab tsis yog - kuaj kev puas tsuaj los ntawm eddy tam sim no, ultrasonic thiab laser scanning rau sab hauv qhov tsis zoo thiab qhov tseeb.
Qib Xaiv los ntawm Daim Ntawv Thov
High -cov neeg caij tsheb ceev: R260 lossis R260Mn rau kev hnav thiab tus nqi sib npaug; R350HT qhov twg nkhaus yog nruj los yog tsheb khiav ceev.
Hnyav-haul freight: R350HT ntawm nkhaus thiab qib uas hnav dominates; R260 ntawm tangent khiav nrog nruab nrab tonnage.
Mixed- txoj kev tsheb khiav: R260 yog qib qub, nrog R350HT tshwj tseg rau txoj kev nkhaus thiab kev rov ua dua tshiab.
Lub teeb lossis qis -cov kab kev lag luam ceev: R200 tuaj yeem txiav txim siab qhov hnav tsis yog qhov txwv.
Kev Ntseeg Tsis Zoo
UIC60 thiab 60E1 yog qhov sib txawv. Lawv yog tib qhov profile nyob rau hauv ob txoj kev xaiv; EN 13674-1 siv 60E1 kev xaiv
Qhov hnyav ntawm txoj kev tsheb ciav hlau yog 60 kg ib 'meter'. Nominal hnyav yog 60.21 kg / m.
Ib txoj kev tsheb ciav hlau nyuaj yog ib txwm zoo dua. R350HT tus nqi ntau dua, yog qhov nyuaj rau vuam thiab muaj kev cuam tshuam ntau dua rau kev puas tsuaj; Kev xaiv qib yuav tsum ua raws li txoj kev npaj tsheb thiab tu.
Kev kam rau siab yog kev nthuav dav ntau lawm. Profile kam rau ua chav kawm cuam tshuam rau lub rooj zaum, phaj phaj haum thiab tus cwj pwm tsis zoo, yog li nws yog qhov yuav tsum tau ua, tsis yog qhov nthuav dav.
Cov lus nug nquag
Q1: EN 13674-1 yog dab tsi?
TS EN 13674-1 Cov txheej txheem European rau kev tsheb ciav hlau ntawm 46 kg / m thiab siab dua, txhais cov duab geometry, qib steel, cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm ntev.
Q2: Puas yog UIC60 zoo ib yam li 60E1?
Yog lawm. UIC60 yog tus qauv UIC thiab 60E1 yog EN lub npe ntawm tib lub tiaj tus - hauv qab rail profile.

Nominal loj yog 60.21 kg ib 'meter', nrog ib tug profile qhov siab ntawm 172 hli, lub hauv paus dav ntawm 150 hli thiab lub taub hau dav ntawm 74.3 hli.
Q4: Dab tsi steel qib yuav tsum tau siv rau hnyav thauj khoom?
Rau hnyav qag loads thiab ntse nkhaus, R350HT muab lub neej ntev tshaj plaws; R260 yog haum rau nruab nrab tonnage ntawm tangent khiav.
Q5: Vim li cas kev kam rau siab yog qhov tseem ceeb rau txoj kev tsheb ciav hlau?
Tight tolerances xyuas kom tseeb clip thiab baseplate zaum, haum fishplate haum, thiab ruaj khov dynamic cwj pwm, uas ua ke yuav txo tau hnav thiab ntev khiav lub neej.
Q6: Puas yog EN 13674-1 rails haum rau cov kab nrawm?
Yog lawm. Lub 60E1 profile nrog cov chav kawm ncaj ncees A thiab qib xws li R260 thiab R350HT yog qhov kev xaiv tus qauv rau siab - khiav ceev.
