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.
Ntawm cov qib sib txawv rail,ua 71mntau 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.
Cov tshuaj muaj pes tsawg leeg ntawm U71Mn yog dab tsi?
U71Mn yog ib qho siab -manganese, siab- carbon rail hlau, feem ntau yog tsim los ntawm Hlau (Fe) nrog cov ntsiab lus tseem ceeb: Carbon (C) nyob ib ncig ntawm 0.65-0.77%, Manganese (Mn) 1.10-1.50%, thiab Silicon (Si) 0.15% horus ntawm 0.3% thiab phosp. Sulfur (S), feem ntau<0.05% each, to enhance strength and wear resistance for heavy rail applications.
Kev sib xyaw ua ke (qhov hnyav %):
- Cov pa roj carbon (C): 0.65% - 0.77%
- Manganese (Mn): 1.10% - 1.50%
- Silicon (Si): 0.15% - 0.35%
- Phosphorus (P): Tsawg dua lossis sib npaug rau 0.04% (lossis<0.05%)
- Sulfur (S): Tsawg dua lossis sib npaug li 0.04% (lossis<0.05%)
- Hlau (Fe): Sib npaug
| Qib Steel | C(%) | Si | Mn | Cr | V | P | S | Tensile zog (Rm / MPa) |
| ua 71mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | Tsawg dua lossis sib npaug li 0.035 | Tsawg dua lossis sib npaug li 0.030 | Ntau dua lossis sib npaug rau 880 |
Cov yam ntxwv tseem ceeb:
- Cov ntsiab lus ntawm cov pa roj carbon monoxide siab: Pab txhawb qhov nyuaj thiab lub zog.
- Cov ntsiab lus Manganese siab: Txhim kho lub zog, tawv, thiab hnav tsis kam, ua rau nws haum rau siab - kev siv tsheb ciav hlau.
- Lub hom phiaj: Siv rau hnyav - txoj haujlwm railway rail, muab kev hnav zoo heev thiab muaj peev xwm tiv taus hnyav thiab cuam tshuam.
Dab tsi yog qhov zoo ntawm kev siv U71Mn los tsim Steel Rail?
Siv U71Mn steel rau kev tsheb ciav hlau muaj qhov zoo xws li lub zog siab, hnav zoo heev, kev ua haujlwm zoo qaug zog, thiab tsim nyog rau cov khoom hnyav thiab hnyav, ua rau nws zoo tagnrho rau kev siab -ceev thiab hnyav- txoj haujlwm railways, chaw nres nkoj, thiab mining, ua tsaug rau nws cov tshuaj muaj pes tsawg leeg (carbon, manganese, thiab lwm yam) thiab muaj peev xwm ua tau zoo dua {- thiab qis dua.
Cov txiaj ntsig tseem ceeb:
- High Strength & Durability: U71Mn steel muab lub zog tensile siab thiab dabtsi yog khoov tsis kam, tseem ceeb heev rau kev thauj cov tsheb ciav hlau hnyav thiab cuam tshuam, txo cov kev xav tau kev saib xyuas.
- Superior Wear & Abrasion Resistance: Nws muaj pes tsawg leeg, tshwj xeeb tshaj yog nrog ntxiv manganese, tsim ib qho tawv tawv uas tiv taus hnav thiab corrugation, ua rau lub neej ua haujlwm ntev, tshwj xeeb tshaj yog nyob rau hauv siab - daim ntawv thov ceev.
- Txhim kho lub neej qaug zog: Cov kev tswj hwm cov ntsiab lus ua rau kev ua haujlwm qaug zog zoo dua thiab tiv thaiv kev tawg tawm, qhov tseem ceeb rau kev ua haujlwm txuas ntxiv.
- Adaptability to Harsh Environments: U71Mn steel, nrog rau cov qauv tsim nyog (xws li U71MnG), tuaj yeem tswj xyuas cov khoom zoo thiab muaj kev cuam tshuam rau qhov kub thiab txias hauv qhov chaw qis, zoo li cov pom ntawm Qinghai-Tibet Railway.
- Versatility for Heavy-Kev Siv Lub Luag Haujlwm: Nws yog dav siv hauv hnyav- txoj kev tsheb ciav hlau, siab - cov kab ceev, thiab cov chaw lag luam (chaw nres nkoj, mines) qhov tshwj xeeb ua haujlwm nyob rau hauv kev thauj khoom loj.
- Txhim kho Weldability (nrog cov txheej txheem tsim nyog): Thaum muaj kev sib tw, kev vuam tshwj xeeb (xws li flash-kev sib txhuam hybrid) thiab kev kho cua sov tuaj yeem ua kom zoo dua microstructure, ntxiv dag zog rau kev sib koom tes thiab kev sib tw.
Dab tsi ntawm steel rails tuaj yeem siv U71Mn los tsim khoom?
U71Mn steel feem ntau yog siv rau kev tsim khoomhnyav - lub luag haujlwm crane rails(zoo li QU70, QU80, QU100, QU120) rau cov chaw nres nkoj, docks, thiab mines, nrog rauhnyav railway rails(zoo li GB qauv 43kg, 50kg, 60kg) rau cov kab tseem ceeb thiab kev tsheb ciav hlau, muab kev hnav zoo tshaj plaws thiab lub zog rau kev thauj khoom siab thiab cuam tshuam. Nws cov ntsiab lus carbon thiab manganese siab muab qhov zoo tshaj plaws hardness thiab toughness, ua rau nws zoo tagnrho rau kev thov.
