Lub tsheb ciav hlau steel yog ib feem ntawm cov hlau dov uas tsim los coj cov tsheb ciav hlau log, faib cov log tsheb rau cov neeg pw tsaug zog thiab ballast, thiab tswj xyuas cov kab lus meej meej raws li kev rov ua haujlwm ntau dua.
Qhov tseeb qhov hnyav ntawm 60 kg rail yog dab tsi?
60 kg rail yog hais txog ib lub tsheb ciav hlau steel uas nws qhov hnyav yog 60 kilograms ib 'meter', thiab nws yog ib qho ntawm cov khoom siv hnyav tshaj plaws -cov haujlwm tsheb ciav hlau rau txoj kev tsheb ciav hlau loj, hnyav- tsheb thauj khoom txoj hauv kev, thiab siab - kev tsheb ciav hlau ceev. Hauv kev tsim kho kev tsheb ciav hlau thoob ntiaj teb, cov tsheb ciav hlau hauv chav kawm 60 kg / m sawv cev rau qhov chaw pib uas cov kab ke hloov pauv ntawm nruab nrab - lub luag haujlwm rau hnyav - lub luag haujlwm hauv lub luag haujlwm, txhawb nqa siab dua qag thiab lub neej ua haujlwm ntev dua.
Ntau lub teb chaws thiab cov koom haum siv cov ntaub ntawv zoo sib xws tab sis tsis zoo ib yam hauv chav kawm 60 kg. Cov lus hauv qab no sib piv cov sib npaug thoob ntiaj teb feem ntau.
| Standard System | Rail Designation | Qhov hnyav (kg / m) | Ntev Ntev (m) |
|---|---|---|---|
| EN / UA | UIC60 (60E1) | 60.21 | 12.5, 25, 50, 100 (CWR) |
| Tuam Tshoj GB | 60 kg Rail | 60.64(qee qhov profile 60.00) | 12.5, 25, 100 |
| AREMA (USA) | 136 ROJ | 67.56(tsis muaj tseeb 60 kg chav kawm) | 12–25 : kuv |
| Russia GOST | R65 | 64.88 | 12.5, 25 |
| JIS | 60 kg Rail | 60.80 | 12.5, 25 |
Txawm hais tias UIC60 feem ntau raug xa mus rau thoob ntiaj teb raws li "60 kg rail," nws qhov tseeb yog60,21 kg ib m, uas yog suav hais tias yog lub thoob ntiaj teb benchmark rau hnyav mainline rail. GB txheem 60 kg rails yog ze heev nyob rau hauv geometry thiab kev ua tau zoo, tab sis qhov tseeb loj thiab lub taub hau qhov ntev yuav txawv me ntsis. GNEE RAIL muab UIC60, GB 60 kg, thiab sib npaug profiles rau hla- ciam teb thiab thoob ntiaj teb railway tej yaam num, nrog rau tag nrho qhov ntev ntawm cov ntaub ntawv pov thawj thiab ntawv pov thawj.
Ib Daim Ntawv Qhia Tag Nrho Qhov hnyav npaum li cas?
Txij li cov tsheb ciav hlau raug xaj thiab thauj los ntawm qhov ntev, cov neeg yuav khoom feem ntau yuav tsum tau suavtag nrho daim hnyav, tsis yog qhov hnyav ib 'meter' xwb. Qhov hnyav tiag tiag nyob ntawm qhov ntev ntawm kev tsheb nqaj hlau.
| Hom Rail | Qhov hnyav (kg / m) | Ntev (m) | Nyhav ib thooj (kg) |
|---|---|---|---|
| UAS 60 | 60.21 | 12.5 | ≈ 753 |
| UAS 60 | 60.21 | 25 | ≈ 1,505 |
| wb 60kg | 60.64 | 25 | ≈ 1,516 |
| UIC60 (CWR) | 60.21 | 100 | ≈ 6,021 |
Rau kev txuas txuas txuas txuas txuas (CWR) cov phiaj xwm, cov ntsia hlau feem ntau muab nkag rau hauv50m, 75m, lossis 100m ntev, uas ua rau kom muaj kev thauj mus los thiab tuav cov cai thiab yuav tsum tau koom tes nrog cov khoom siv hauv qhov chaw.
Vim li cas 60 kg Rail Nyhav tseem ceeb rau kev khiav haujlwm?
Txoj kev tsheb ciav hlau qhov loj ntawm ib 'meter' ncaj qha cuam tshuam rau nwskhoov txhav, qaug zog tiv thaiv, thiab kev pab lub neej. Heavier rails tuaj yeem tiv taus ntsug deflection, hnav lub taub hau, thiab dov kev qaug zog, tshwj xeeb tshaj yog nyob rau hauvsiab qag loads thiab siab -ceev tej yam kev mob. Piv nrog rau cov hlua sib zog xws li 50 kg / m lossis 43 kg / m, 60 kg rail muab kev txhim kho kev thauj mus los rau cov neeg pw tsaug zog thiab ballast, uas txo cov kev tswj xyuas zaus thiab txhawb kev soj ntsuam ntev dua.
| Kev faib tawm | Qhov siab (mm) | Lub taub hau (mm) | Hauv qab (mm) | Thickness (mm) | Qhov hnyav (kg / m) | |
| Lub Teeb Rail | 8 KG / M | 65 | 25 | 54 | 7 | 8.42 |
| 9 KG / M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |
| 12 KG / M | 69.85 | 38.1 | 69.85 | 7.54 | 12.2 | |
| 15 KG / M | 79.37 | 42.86 | 79.37 | 8.33 | 15.2 | |
| 18 KG / M | 80 | 40 | 80 | 10 | 18.06 | |
| 22 KG / M | 93.66 | 50.8 | 93.66 | 10.72 | 22.3 | |
| 24 KG / M | 107 | 51 | 90 | 10.9 | 24.46 | |
| 30 KG / M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
Los ntawm qhov kev xav ntawm qhov system, lub tsheb ciav hlau yuav tsum tau sib phim nrogtsim nyog sleepers, fastening systems, thiab rail pads, txwv tsis pub cov qauv zoo ntawm cov tsheb ciav hlau hnyav tsis tuaj yeem siv tag nrho.
Qhov tseeb qhov hnyav ntawm "60 kg rail" yog kwv yees li 60 kg ib 'meter', nrog rau cov txiaj ntsig xws li 60.21 kg / m (UIC60) lossis cov duab siab dua me ntsis raws li GB thiab JIS cov qauv vim muaj qhov sib txawv ntawm qhov profile. Qhov tseem ceeb tshaj plaws hauv kev ua haujlwm engineering tsis yog tsuas yog qhov hnyav nominal xwb, tab sis kuj ua raws li qhov siab ntev, tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lub taub hau - hardening yuav tsum tau raws li tus qauv siv tau.
Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv hlau sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.
