Jan 21, 2026
Hlau railyog ib qho kub -rolled steel profile nrog tus qauv ntoo khaub lig- ntu uas muaj lub taub hau tsheb ciav hlau, lub vev xaib, thiab lub hauv paus, tsim los coj lub log, dais rov qab ntsug thiab sab nraub qaum, thiab xa cov kev ntxhov siab kom nyab xeeb rau cov neeg pw tsaug zog thiab lub hauv paus khiav. Nws yog qhov tseem ceeb ntawm kev thauj khoom-cov kabmob ntawm cov kab tsheb ciav hlau thiab cov tsheb ciav hlau, thiab nws cov khoom xaiv ncaj qha txiav txim siab txog kev nyab xeeb, hnav tsis kam, thiab kev pabcuam lub neej. Cov kev tsheb ciav hlau niaj hnub no vam khom tshwj xeeb hauv kev tsim tsheb ciav hlau es tsis yog cov qauv hlau zoo tib yam.
Hom hlau twg yog siv hauv kev tsheb ciav hlau?
Txoj kev tsheb ciav hlau feem ntau yog tsim los ntawm siab -carbon, siab -manganese carbon steel lossis qis- alloy steel, tsim los ua kom muaj zog, zoo toughness, thiab zoo heev hnav tsis kam. Cov qib siv dav tshaj plaws suav nrog U71Mn thiab U75V hauv GB qauv, R260 thiab R350HT hauv EN cov qauv, thiab 900A hauv AREMA cov qauv. Cov hlau no muaj cov qib tswj cov pa roj carbon monoxide los txhim kho hardness thiab manganese los txhim kho lub zog thiab qaug zog tiv thaiv, thaum taug qab alloying ntsiab xws li vanadium lossis chromium tuaj yeem raug ntxiv rau kev txhim kho kev ua haujlwm ntxiv hauv kev siv hnyav{10}}.

Vim li cas thiaj siab -Carbon thiab Alloyed Steels tsim nyog rau Rail Tracks?
Ntawm lub log-rail interface, kev sib cuag nrog kev ntxhov siab yog qhov siab heev thiab rov ua tsis tu ncua, uas tuaj yeem ua rau ntog, yas deformation, thiab dov kev sib cuag qaug zog yog tias cov hlau tsis txaus thiab muaj zog. Cov ntsiab lus carbon siab ua rau muaj zog thiab hnav tsis kam, thaum manganese txhim kho lub zog thiab hardenability, tso cai rau lub taub hau tsheb ciav hlau kom muaj kev ncaj ncees tom qab tswj tau txias lossis lub taub hau- kho hardening. Nyob rau hauv qib siab dua - qib rails, micro-alloying ntsiab xws li vanadium tej zaum yuav muab ntxiv rau refine grain qauv thiab txhim kho kev qaug zog.
Rau cov kab thauj khoom hnyav hnyav thiab cov crane khiav, cov tsheb ciav hlau yuav tsum tiv taus cov khoom muaj zog thiab cov quab yuam sab nraud. Yog li ntawd,GNEE RAILDIN536 crane rails (A65-A150) thiab QU crane rails (QU70-QU120) feem ntau yog tsim los ntawmU71Mn lossis U75V steel, muab siab dua hardness thiab ntev kev pab cuam lub neej piv nrog cov qauv railway rails. Rau railway mainlines, GNEE RAIL muab cov qib xws liU71Mn, U75V, R260, R350HT, thiab 900A, kom ntseeg tau tias muaj kev sib raug zoo nrog ntau lub qag loads, tsheb ceev ceev, thiab cov tswv yim txij nkawm.

Kev xaiv cov rail steel hlau tsis yog tsuas yog xaiv cov qib tab sis kuj sib piv nrog hom profile, fastening stiffness, thiab ib puag ncig.GNEE RAILtxhawb nqa cov haujlwm nrog kev xaiv kev tsheb ciav hlau raws li kev thauj khoom qag, lub log siab, tsheb khiav ntau zaus, thiab kev ua haujlwm ib puag ncig, muab cov kev tsheb ciav hlau ua raws li GB, EN, UIC, DIN, AREMA / ASCE, JIS, thiab AS cov qauv. Ntxiv rau cov khoom lag luam, GNEE RAIL muaj cov kev daws teeb meem kev tsheb ciav hlau, suav nrog cov tshuaj lom neeg tshwj xeeb tswj thiab tswj cov txheej txheem txias kom ua kom zoo dua qhov tawv tawv-tawv tawv rau kev xav tau kev pabcuam.
