Ahlau railyog txhais los ntawm nws tus ntoo khaub lig-sectional profile, muaj lub taub hau, web, thiab ko taw, engineered los tiv thaiv dabtsi yog khoov, hnav, thiab ib puag ncig kev nyuaj siab. Raws li tus neeg muag khoom,GNEE RAILmuab rails nyob rau hauv ntau yam profiles, xws li DIN536, UIC, BS11: 1985, thiab AREMA / ASCE qauv thiab lwm yam. Peb cov kev pab cuam muaj xws li customized ntev ntau lawm, vuam los yog koom cov kev daws teeb meem, thiab cov tswv yim tswv yim ntawm load- bearing optimization, xyuas kom meej cov rails raws li kev lag luam thiab kev thauj mus los.
Vim li cas cov hlau siv hauv kev tsheb ciav hlau?
Hlau yog siv nyob rau hauv txoj kev tsheb ciav hlau vim nws muab kev sib xyaw ua ke zoo tshaj plaws ntawm lub zog, durability, hnav tsis kam, thiab cov nqi ua haujlwm yuav tsum tau ua kom ntev - lub sij hawm, hnyav - lub luag haujlwm kev tsheb ciav hlau. Los ntawm ob qho tib si engineering thiab kev lag luam pom, steel yog cov khoom siv zoo tshaj plaws rau kev tsheb nqaj hlau. Cov laj thawj tseem ceeb yog raws li hauv qab no.
Ua ntej,steel muaj siab load-cov kabmob muaj peev xwm thiab qaug zog. Railway rails yuav tsum nqa rov qab qag loads los ntawm cov tsheb ciav hlau uas muaj peev xwm tshaj kaum tons ntawm ib lub log, ntau lab lub sij hawm nyob rau hauv lawv cov kev pab cuam lub neej. High- carbon thiab alloy rail steels xws li U71Mn, U75V, thiab R260/R350HT yog tsim los tiv thaiv kev qaug zog tawg thiab yas deformation, uas yog qhov tseem ceeb rau kev tswj xyuas cov duab geometry thiab tiv thaiv kev ua tsis tiav.
| Qib | Standard / cheeb tsam | Kev sib xyaw ua ke (wt%) |
| R260 | TS EN 13674-1 (Tebchaws Europe) | C: 0.67–0.80, Mn: 0.90–1.20, Si: Tsawg dua lossis sib npaug rau 0.50 |
| R350 HT | TS EN 13674-1 (Tebchaws Europe) | C: 0.75–0.85, Mn: 0.80–1.20, Cr: 0.20–0.50 |

Thib ob,steel muaj kev hnav zoo heev ntawm lub log-rail kev sib cuag nto. Qhov chaw sib cuag ntawm lub log thiab tsheb ciav hlau yog qhov me me, tsim kom muaj kev sib cuag siab heev. Thaum tshav kub kub zoo- kho steel rails tuaj yeem tiv taus lub taub hau, hnav sab nrauv, thiab corrugation, ncua kev pab cuam lub neej thiab txo cov nqi tu. Qhov no yog ib qho tseem ceeb sib npaug rau cov crane ntsia, qhov twg cov log tsheb hnyav hnyav thiab qeeb, rov ua dua tshiab ua rau hnyav hnyav hnyav.
Peb,steel muab zoo toughness thiab cuam tshuam tsis kam, uas yog ib qho tseem ceeb rau kev nyab xeeb. Rails yuav tsum zam qhov cuam tshuam los ntawm lub log tiaj tus, lub zog nres, qhov kub thiab txias - ua rau muaj kev ntxhov siab, thiab kev thauj khoom tsis zoo ntawm cov pob qij txha thiab cov keyboards. Cov hlau tuaj yeem nqus tau cov kev poob siab no yam tsis muaj kev puas tsuaj, tshwj xeeb tshaj yog thaum alloyed thiab tswj-txias thaum tsim khoom.
Plaub,steel yog tsim rau vuam thiab nruam kev tsim kho. Niaj hnub nimno railways thiab crane systems cia siab heev rau flash-tooj vuam thiab thermite welding kom ntev, nruam rails, uas txhim kho kev caij tsheb, txo suab nrov, thiab txo kev txij nkawm ntawm cov pob qij txha. Hlau cov khoom siv hlau ua kom muaj zog, txhim khu kev qha welded pob qij txha thaum ua raws li cov txheej txheem.
Hlau ntsia hlau kuj sib xyaw ua ke zoo nrog cov txheej txheem fastening, rail pads, puag daim hlau, thiab cov neeg pw tsaug zog, ua kom tiav cov qauv uas tuaj yeem tsim kho rau qhov sib txawv ceev, loads, thiab ib puag ncig.GNEE RAILmuab tsis tau tsuas yog tsheb ciav hlau rails thiab crane rails nyob rau hauv ntau yam thoob ntiaj teb cov qauv, tab sis kuj txuam fasteners, rail clips, pads, thiab customized technical support, kom ntseeg tau tias qhov zoo ntawm steel rails tau tiav nyob rau hauv tiag tiag tej yaam num.
