Lub ntsiab lus ntawm txoj kev tsheb ciav hlau yog dab tsi?
Atsheb ciav hlau rail, ntau precisely hu ua ahlau rail, yog kub- dov steel profile ntsia longitudinally ntawm sleepers los ua tus khiav nto thiab kev taw qhia rau tsheb ciav hlau log. Nws yog qhov tseem ceeb ntawm kev thauj khoom-cov kabmob ntawm txoj kev tsheb ciav hlau, lub luag haujlwm rau kev nqa lub log loads, tswj ntsuas ntsuas, thiab xa cov rog kom nyab xeeb rau hauv pw tsaug zog, ballast, thiab subgrade. Tsis zoo li cov qauv hlau dav dav, rail hlau yog tsim tshwj xeeb los tiv thaiv hnav, qaug zog, thiab rov ua kom muaj kev ntxhov siab los ntawm kev hla kev tsheb ciav hlau.
Hauv kev siv hluav taws xob tsim hluav taws xob, lo lus "tsheb ciav hlau" feem ntau yog hais txog ob khub ntawm cov hlau sib txuas uas txhais cov ntsuas kev ntsuas thiab xyuas kom meej tias lub log flanges khaws cov tsheb kom raug raws txoj kev, txawm nyob rau hauv txoj kev tsheb ciav hlau loj, metro, tramways, lossis kev lag luam lem.
Dab tsi yog Cov Qauv ntawm Hlau Rail?
Tus qauv kev tsheb ciav hlau muaj qhov ua kom zoo dua I-zoo li tus hla ntu uas muaj peb thaj chaw ua haujlwm:
| Rail Part | Muaj nuj nqi hauv Kev Pabcuam | Lub Hom Phiaj Engineering |
|---|---|---|
| Rail taub hau | Kev sib cuag log ncaj qha | Resistant hnav thiab dov kev qaug zog |
| Rail Web | Txuas taub hau thiab ko taw | Transfers ntsug thiab lateral loads |
| Rail Foot (Pib) | So ntawm cov ntaub qhwv los yog daim hlau | Muab kev ruaj ntseg thiab load faib |
Qhov geometry no ua rau kev khoov siab tshaj plaws thaum txo qis kev siv cov khoom siv, uas yog vim li cas tib lub ntsiab lus hla ntu yog siv hauv UIC, EN, AREMA, GB, JIS, thiab lwm yam qauv thoob ntiaj teb.
Specifications ntawm Txawv tus qauv steel rail rail
Raws li tus kws tshaj lij kev tsheb nqaj hlau xa khoom, GNEE RAIL tuaj yeem muab cov qauv sib txawv steel hlau xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.

Vim li cas Steel siv rau tsheb ciav hlau?
Rails yog tsim los ntawm siab -carbon pearlitic steel lossis cua sov- kho alloy steel vim tias cov ntaub ntawv no muab kev sib xyaw zoo tshaj plaws ntawm hardness, toughness, thiab qaug zog. Cov qhab nia xws li U71Mn, R260, R350HT, thiab 900A, uas tau teev tseg raws li GB, EN, UIC, thiab AREMA cov qauv. Cov hlau no tiv taus ntau lab lub log hla thaum tswj kev ncaj ncees ntawm qhov chaw thiab lub zog ntawm cov qauv.

Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm cov qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug khoom, GNEE ua tau zoo steel rails uas tau raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
