Dab tsi yog Steel Rail Standards?
Cov qauv kev tsheb ciav hlau steel yog cov kev qhia tshwj xeeb uas txhais cov khoom sib xyaw, hla -section geometry, qhov ntev ntev thiab kev ua haujlwm ntawm cov ntsia hlau. Lawv muaj nyob rau hauv thiaj li hais tias ib tug rail tsim los ntawm ib lub zeb yuav tsum tau ntsia thiab tswj interchangeably nrog rails los ntawm lwm qhov chaw, thiab thiaj li hais tias lub log, pw tsaug zog thiab fastening systems yuav tsum tau matched rau txoj kev tsheb ciav hlau. Txhua cheeb tsam tau tsim nws tus qauv tsev neeg - AREMA thiab ASTM hauv North America, EN thiab UIC hauv Europe, GB thiab TB hauv Suav teb, JIS hauv Nyij Pooj, BS hauv UK - thiab txhua tus qhia cov profile los ntawm nominal mass per meter (piv txwv li 60 kg / m rail) ua ke nrog cov qib steel tso cai rau qhov profile ntawd.
Cov Ntsiab Lus Tseem Ceeb Tshaj Tawm los ntawm Rail Standards
Khoom muaj pes tsawg leeg:carbon, manganese, silicon thiab alloying ntsiab txwv uas tswj hardness, weldability thiab qaug zog kuj.
Dimensions thiab geometry:lub taub hau, lub vev xaib thiab ko taw profile, ntxiv rau kev ncaj thiab twist tolerances, kom ntseeg tau tias kev sib raug zoo nrog cov log thiab fastenings.
Mechanical zog:tensile lub zog, tawm los lub zog, hardness, cuam tshuam toughness thiab hnav tsis kam yuav tsum tau.
Qib Performance:Piv txwv li R260 thiab R350HT hauv EN 13674-1, kom tus neeg yuav khoom tuaj yeem sib tw tsheb ciav hlau lub zog rau qag load thiab ceev.
Kev tshuaj xyuas thiab kuaj:sampling, kuaj ultrasonic, hardness kuaj thiab txais cov qauv.

Yuav Ua Li Cas Xaiv Tus Qauv Zoo
Xaiv tus qauv uas phim koj lub network kev khiav hauj lwm lossis kev lag luam xa tawm, tom qab ntawd xaiv qhov loj ntawm ib lub 'meter' los ntawm qag load thiab ceev, thiab thaum kawg paub meej cov qib steel los ntawm kev hnav thiab weldability. Rau kev lag luam thiab kev siv crane, GB lub teeb rail thiab QU crane rail, DIN 536 crane rail thiab JIS E 1103 yog ib qho; Rau cov tsheb loj, EN 13674, AREMA thiab GB hnyav tsheb ciav hlau siv. Cov neeg muag khoom xws li GNEE RAIL muab cov ntsia hlau, clips, bolts, baseplates, roj hmab ncoo thiab cov khoom siv thauj tog rau nkoj raws li qhov sib koom ua ke kom txhua qhov kev sib tshuam yog qhov sib xws.
Cov lus nug nquag
60 kg / m txhais li cas hauv kev tsim tsheb ciav hlau?
Nws yog lub nominal loj ntawm ib 'meter' rail. Nws yog ib qho shorthand rau lub peev xwm load thiab nruj ntawm seem: hnyav rail nqa ntau qag loads thiab resists dabtsi yog khoov zoo dua. Qhov ntsuas qhov tseeb ntawm 60 kg / m seem feem ntau txawv me ntsis ntawm tus nqi nominal (piv txwv li 60.64 kg / m).
Dab tsi yog qhov txawv ntawm EN 13674 thiab UIC 860?
UIC 860 yog cov qauv kev tsheb ciav hlau nyob sab Europe, txhais cov ntu xws li UIC54 thiab UIC60. TS EN 13674-1 (txoj hlua) thiab EN 13674-4 (seem) yog cov qauv European tam sim no uas hloov pauv lub tebchaws thiab UIC kev tsheb ciav hlau tshwj xeeb, siv cov npe xws li 54E1 thiab 60E1 nrog qib steel R200 txog R370CrHT. Feem ntau UIC seem tseem siv tau raws li EN ntu nrog cov duab geometry zoo ib yam.
Puas yog AREMA thiab ASCE yog tib txoj kev tsheb ciav hlau?
ASCE yog cov laus American Society of Civil Engineers seem series (ASCE 25 txog ASCE 175), tseem siv dav rau lub teeb thiab kev tsheb ciav hlau. AREMA yog tam sim no railway engineering koom haum tus qauv uas nws 100RE, 115RE thiab 136RE seem yog cov niaj hnub hnyav rail profiles rau North American freight networks.
Vim li cas tib txoj kev tsheb ciav hlau tuaj hauv cov qib steel sib txawv?
Vim kev tsheb sib txawv. Cov kab hluav taws xob muaj peev xwm siv tau qis dua - qib nqi, thaum hnyav - txoj kab nkhaus xav tau cua sov- qib kho nrog siab hardness thiab qaug zog. Cov qauv yog li tso cai rau ntau qib rau ib ntu, piv txwv li R200 rau R350HT rau 60E1, thiab tus neeg yuav khoom xaiv qib rau lub luag haujlwm.
Dab tsi yog qhov txawv ntawm crane rail thiab railway rail?
Crane rails muaj lub taub hau dav dav thiab yog tsim los nqa hnyav hnyav hnyav loads ntawm qis ceev raws crane girders; piv txwv li GB QU70-QU120 thiab DIN 536 A45-A150. Railway rails muaj lub taub hau profiled sib phim rau tsheb ciav hlau log thiab yog tsim los rau kev kub ceev khiav nrog kev taw qhia sab.
Kuv yuav siv tus qauv twg rau kev tsheb ciav hlau mining?
Rau mine thiab industrial lem, GB lub teeb rail (8-30 kg / m) los yog GB hnyav rail (38-43 kg / m), ASCE seem, DIN 5901 lub teeb rail thiab JIS 22-37 kg seem yog tag nrho cov. Qhov kev xaiv yog nyob ntawm lub qag load, ceev thiab fastening system twb nyob rau hauv kev pab cuam ntawm qhov chaw.
