U71Mn rail specification yog dab tsi?
Jan 20, 2026
Hlau railsyog cov khoom tseem ceeb hauv kev thauj mus los hauv kev lag luam, warehouse crane lem, thiab logistics networks. Lawv muab cov kev taw qhia ruaj khov rau cov tsheb log, dais dynamic thiab zoo li qub loads, thiab tswj kev sib raug zoo raws li kev ua haujlwm tas mus li. High- zoo steel rails muab lub zog, toughness, thiab hnav tsis kam los xyuas kom meej ntev - lub sij hawm cia siab, txo kev txij nkawm, thiab txhawb nqa hnyav los yog rov ua dua kev lag luam. Kev xaiv kev tsheb ciav hlau kom raug yog qhov tseem ceeb rau cov chaw tsim khoom, chaw nres nkoj, tsev khaws khoom, thiab cov kab tsheb thauj mus los ib ntus kom tau txais kev nyab xeeb thiab ua haujlwm tau zoo.
Ntawm cov qib sib txawv ntawm kev tsheb nqaj hlau, U71Mn tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev lag luam crane rails thiab hnyav- cov kab tsheb thauj mus los vim nws qhov sib xyaw ua ke ntawm lub zog siab, hnav tsis kam, thiab kev cuam tshuam toughness.
U71Mn rail specification yog dab tsi?
U71Mn rails yog tsim los muab kev ua haujlwm zoo nyob rau hauv kev thauj khoom hnyav thiab rov ua dua qhov kev ntxhov siab.
| Khoom | ua 71mn | Chav tsev | Sau ntawv |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug rau 380 | MPa | Txhawb nqa dynamic loads hauv kev ua haujlwm crane |
| Tensile zog | 880–1080 | MPa | Resistant pob txha nyob rau hauv lub siab tshaj plaws kev nyuaj siab |
| Hardness | 350–450 | HB | Muab siab hnav tsis kam |
| Elongation | Ntau dua lossis sib npaug li 12% | % | Balances toughness thiab lub zog |
| Cov pa roj carbon | 0.63–0.73 | % | Siab-lub zog qis- cov ntsiab lus alloy |
| Manganese | 1.35–1.65 | % | Txhim kho hnav tsis kam thiab toughness |
U71Mn rails yog tshwj xeeb tshaj yog haum rauhnyav kev lag luam cranes, chaw nres nkoj ua haujlwm, thiab siab -cov haujlwm logistics kab, qhov twg hnav tsis kam thiab kev cuam tshuam toughness yog qhov tseem ceeb rau kev ua haujlwm ntev -.
Cov qauv twg thiab cov Profiles koom nrog U71Mn Rails?
U71Mn rails yog tsim raws liSuav GB / T 2585-2007 tus qauvthiab tuaj yeem muab nkag rau hauv ntau qhov kev lag luam rail profiles rau kev siv hauv tsev thiab thoob ntiaj teb:
- Rail hnyav:50kg / m, 60kg / m, 75kg / m, nyob ntawm kev ua haujlwm load thiab crane hom
- Rail qhov siab:Feem ntau 150mm, 160mm, 180mm, hloov kho rau kev teeb tsa tshwj xeeb
- Custom lengths:Muab raws li qhov xav tau ntawm qhov project, nrog rau kev xaiv rau ua ntej -drilled xaus los yog nkhaus seem
| 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 | |

| 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 | |
| Heavy Rail | 38 KG / M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG / M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG / M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG / M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG / M | 176 | 73 | 150 | 16.5 | 60.64 | |
U71Mn rails kuj tuaj yeem hloov kho kom haumDIN, EN, lossis JIS profile sib npaug, tso cai rau cov haujlwm thoob ntiaj teb tau txais txiaj ntsig los ntawm cov hlau cov khoom siv kho tshuab thaum ua raws li cov qauv hauv zos.
