Jan 22, 2026
Hlau railyog hais txog ib qho kev tsim qauv zoo nkauj steel profile uas xa cov nplaim du thiab zoo ib yam rau cov tsheb dov thaum txo qis hnav, kev co, thiab suab nrov.GNEE RAILcov khoom siv rails ua raws li ntau tus qauv thoob ntiaj teb, suav nrog UIC50–UIC60, JIS E1101/E1103, AS1085, thiab AREMA/ASCE 25–175 lb. Peb cov kev pabcuam suav nrog rau -thov txiav rau qhov ntev, kev kho qhov chaw xws li tiaj, zinc-coated{10} kev sib tham ua tiav, thiab cov neeg caij tsheb thiab industrial rail systems.

Dab tsi yog qhov tseem ceeb ntawm kev tsheb nqaj hlau?
Qhov tseem ceeb ntawm txoj kev tsheb ciav hlau yog nyob rau hauv nws lub luag haujlwm tseem ceeb raws li lub hauv paus ntawm kev tsheb ciav hlau - coj kev thauj mus los thiab kev lag luam khoom siv. Rails tsis yog steel tuav nkaus xwb-lawv yog cov precision-engineered Cheebtsam uas ua kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab ua haujlwm ntev hauv ntau daim ntawv thov.
1. Load-Cov kabmob thiab kev nyab xeeb
Rails yog tsim los nqa cov khoom hnyav heev, suav nrog kev siab - cov tsheb ciav hlau ceev, tsheb ciav hlau thauj khoom, thiab nyiaj siv ua haujlwm cranes. Lawv faib qhov hnyav thoob plaws cov neeg pw tsaug zog (kev sib raug zoo) thiab ballast, txo qis kev ntxhov siab ntawm lub hauv paus thiab tiv thaiv kev khiav deformation. Lub luag haujlwm ntawm cov txheej txheem no yog qhov tseem ceeb rau kev nyab xeeb ntawm kev ua haujlwm, txo qis kev pheej hmoo ntawm derailment thiab ncua lub neej ntawm txoj kev tsheb ciav hlau.
2. Kev taw qhia thiab kev ruaj ntseg
Rails muab qhov chaw khiav nrawm uas coj cov log raws txoj kev ruaj khov. Rau cov tsheb ciav hlau, qhov no ua kom muaj kev mus ncig zoo thiab kev sib raug zoo ntawm cov nkhaus thiab gradients. Hauv kev lag luam chaw, xws li cranes thiab chaw nres nkoj ua haujlwm, rails tswj qhov chaw raug rau cov khoom hnyav, tso cai rau cov khoom txav tau zoo thiab nyab xeeb.
3. Durability thiab kev ntseeg siab
High -cov tsheb ciav hlau zoo, zoo li cov uas muaj los ntawmGNEE RAIL, yog tsim los ntawm hnav-cov hlau tsis muaj zog (piv txwv li, U71Mn rau crane rails) uas tuaj yeem tiv taus kev sib txhuam tsis tu ncua, lub zog muaj zog, thiab hnyav ib puag ncig. Tsim kom zoo rails txo kev txij nkawm zaus thiab downtime, txhim kho tag nrho cov kev ntseeg tau.

4. Kev lag luam thiab kev ua haujlwm zoo
Rails ua kom muaj peev xwm siab -muaj peev xwm, qis- kev sib txhuam kev thauj mus los, uas yog lub zog ntau dua -ntau dua li kev thauj mus los rau cov khoom siv loj lossis cov tshuab hnyav. Hauv kev lag luam ib puag ncig, crane rails nce kev tsim khoom los ntawm kev txhawb nqa ceev thiab meej ntawm kev thauj khoom.
5. Versatility hla kev siv
Rails yog adaptable rau ntau yam ntsiab lus:
- Railway systems: Neeg nrog caij thiab freight thauj
- Kev lag luam kev lag luam: nyiaj siv ua haujlwm cranes, gantry cranes, thiab conveyors
- Mining thiab kev tsim kho: hnyav- thauj khoom thauj hauv ib puag ncig tsis zoo lossis tsis zoo
Hlau Rail Hom
Hom kev tsheb ciav hlau raug cais los ntawm kilograms ib meter ntawm txoj kev tsheb ciav hlau ntev. Piv txwv li, steel rails siv nyob rau hauv Tuam Tshoj txoj kev tsheb ciav hlau yog 75kg / m, 60kg / m, 50kg / m, 43kg / m thiab 38kg / m.
- Classified los ntawm Daim Ntawv Thov:GNEE RAIL khoom siv crane rail (QU120, QU100, QU80, QU70), hnyav rail (38, 43, 50, 60, 75kg) thiab lub teeb rail (9,12,15,22,30kg / m).
