Arail ntses phajyog ib qho kev sib koom ua ke uas ua kom lub taub hau ntawm txoj kev tsheb ciav hlau, lub vev xaib, thiab cov hauv paus ntawm ob qhov kev tsheb ciav hlau uas nyob ib sab, kom ntseeg tau tias qhov kev hla ntawm lub sijhawm bending thiab ntsug loads hla qhov tsis sib xws thaum tiv thaiv kev sib txawv txav.GNEE RAILmanufactures ntses daim hlau rau GB lub teeb thiab hnyav rails, UIC txheem rails, DIN536 thiab QU crane rails, JIS rail seem, AS1085 rails, BS11 profiles, thiab AREMA / ASCE rails, thiab muab kev sib koom tsim kev soj ntsuam xyuas thiab installation kev taw qhia.
Cov ntaub ntawv dab tsi ua rau cov ntses niaj hnub?
Niaj hnub nimno railway ntses daim hlau (cov tuav sib koom ua ke) feem ntau yog tsim los ntawm siab - lub zog, cov ntaub ntawv ruaj khov tsim los tiv taus hnyav, dynamic loads. Cov ntaub ntawv tseem ceeb uas siv yog dov los yog forged siab -carbon steel, nruab nrab- carbon steel, thiab tshwj xeeb alloys, xws li cov txhim kho nrog manganese.

Cov khoom siv twg yog qhov ruaj khov tshaj plaws rau kev sib koom ua ke rail?
Thaum tshav kub kub-kho cov pa roj carbon steel, tshwj xeeb yog qib zoo li 45 #, 50Mn, lossis 42CrMo, yog cov khoom siv ruaj khov tshaj plaws rau cov qauv, hnyav -cov haujlwm rail sib koom ua ke, muab lub zog siab thiab qaug zog. Rau cov rwb thaiv tsev, ntev - daim ntaub ntawv siv tau ntev, siab - lub zog forged steel ua ke nrog polyurethane coatings los yog qib siab fiberglass- cov khoom siv ntxiv yog cov kev xaiv zoo tshaj plaws rau kev ua haujlwm ntev.
Cov khoom tseem ceeb Durable:
- Thaum tshav kub kub-Kho tau hlau (Quenched thiab Tempered):Feem ntau 45 #, 50Mn, lossis 42CrMo steel, cov no muab kev sib xyaw zoo tshaj plaws ntawm lub zog, tawv, thiab hnav tsis kam, feem ntau kav ntev tshaj 50 xyoo.
- Microalloyed hlau:Siv rau hauv daim ntawv thov tshwj xeeb los ua kom muaj zog thiab qaug zog tiv thaiv hauv qhov hnyav - thauj khoom.
- High-Lub zog Composite/Fiberglass:Feem ntau siv nyob rau hauv "glued insulated pob qij txha" los muab kev ruaj khov thaum tswj hluav taws xob rwb thaiv tsev ntawm cov tsheb ciav hlau.
Yuav ua li cas yog rail joint bars tsim?
Rail sib koom ua ke (los yog ntses phaj) yog tsim los ntawm cov txheej txheem meej, ntau-theem txheej txheem, feem ntau suav nrog kub dov lossis forging steel, ua raws li kev kho cua sov, drilling / punching, thiab ua tiav kom muaj kev ncaj ncees ntawm cov qauv. Cov khoom no yog tsim los ua kom tau raws li cov kev tsheb ciav hlau tshwj xeeb (piv txwv li, UIC 60, 136 RE) thiab tseem ceeb heev rau kev sib txuas, sib dhos, thiab txhawb nqa txoj kev tsheb ciav hlau.
Cov txheej txheem tseem ceeb ntawm kev tsim khoom
- Raw Khoom Npaj:High- steel muaj zog (feem ntau carbon lossis microalloyed steel) raug txiav kom loj.
- Shaping (Forging los yog Rolling):Cov hlau yog rhuab mus rau qhov kub thiab txias thiab zoo li siv cov forging hammers hnyav los yog tshwj xeeb kub - dov mills los tsim cov profile uas yuav tsum tau (xws li, Angel tuav).
- Kev kho cua sov:Txhawm rau txhim kho cov kav ntev, tawv, thiab lub zog, cov tuav tau txais kev kho cua sov tshwj xeeb, suav nrog cua sov thiab tswj cua txias (quenching thiab tempering).
- Machining thiab Drilling:Cov tuav tau raug txiav kom ntev, nrog cov ntsia liaj qhov rooj qhov drilled los yog xuas nrig ntaus kom ua tau raws li qhov ntev ntev (piv txwv li, ± 1/32 nti rau qhov loj).
- Ua tiav:Cov pob qij txha ua tiav raug ntxuav, tshuaj xyuas qhov tsis xws luag, thiab feem ntau coated nrog cov khoom tiv thaiv tiv thaiv-corrosion.
