rails ua haujlwm li cas?

 

Lub tsheb ciav hlau yog ib qho tseem ceeb ntawm kev tsheb ciav hlau kev tsim kho, muab txoj hauv kev txuas mus ntxiv, ruaj khov, thiab coj txoj hauv kev rau tsheb ciav hlau. Rails ua hauj lwm los ntawm kev txhawb nqa hnyav hnyav ntawm locomotives thiab freight, coj lub log raws txoj kev meej, thiab xa cov khoom thauj no kom nyab xeeb rau cov neeg pw tsaug zog (kev sib txuas) thiab ballast. Tsim kom raug thiab txhim kho cov tsheb ciav hlau kom muaj kev sib tw tsheb ciav hlau, txo kev hnav, thiab tswj kev nyab xeeb.

 

 

Yuav ua li cas Rails txhawb nqa tsheb ciav hlau Loads?

 

Rails dais lub zog ntsug thiab sab nraud ntawm lub tsheb ciav hlau log. Qhov I-zoo li tus ntoo khaub lig- ntu ntawm cov tsheb ciav hlau niaj hnub tso cai rau lawv tiv taus lub sijhawm khoov thiab cuam tshuam. Lub taub hau kev tsheb ciav hlau muab qhov chaw du rau lub log sib cuag, lub vev xaib tiv thaiv lub zog shear, thiab lub hauv paus (ko taw) kis cov khoom thauj mus rau cov neeg pw tsaug zog.

 

 

Rail Section	Muaj nuj nqi
Lub taub hau	Muab ib tug dov nto; txo kev sib txhuam thiab hnav
Web	Resistant ntsug thiab kab rov tav shear zog
Puag	Hloov qhov hnyav rau cov neeg pw tsaug zog thiab ua kom ruaj khov

 

Yuav Ua Li Cas Rails Hloov Loads?

 

Rails faib lub tsheb ciav hlau qhov hnyav ntawm lub log rau cov neeg pw tsaug zog thiab ballast. Cov hlua hnyav dua nrog lub vev xaib tuab thiab lub hauv paus muab kev ruaj ntseg thiab kev ua neej ntev dua, tshwj xeeb tshaj yog nyob rau hauv kev rov ua dua. Piv txwv li, hnyav rail P60 (60 kg / m) muaj peev xwm kis tau siab - neeg nrog caij tsheb ciav hlau loads, thaum lub teeb rail 22 kg / m suits industrial los yog tramway kab.

 

 

Rail Hom	Qhov hnyav (kg / m)	Hom Load Capacity	Siv dav
Lub Teeb Rail	6–30	Tsawg, industrial	Factories, kab luv
Heavy Rail	38–75	Nruab nrab mus rau siab	Neeg nrog caij, freight kab
Crane Rail	70–120	Point loads, siab cuam tshuam	Industrial yards, cranes

Dab tsi yog cov khoom ntawm steel rail?

 

Cov hlau rails feem ntau yog ua los ntawm siab - carbon steel thiab qee zaum alloy hlau, tshwj xeeb yog tsim los rau lub zog siab, hardness, thiab hnav tsis kam, nrog cov ntsiab lus tseem ceeb yog Carbon (C) thiab Manganese (Mn) rau lub zog, feem ntau txhim kho nrog cov ntsiab lus xws li Chromium (Cr) lossis Vanadium (V), thiab tom qab ntawd qee zaum cua sov- kho kom zoo dua. Cov qib zoo li R260 (U75V) thiab R350HT yog siv rau cov kab hnyav-.

Packing & Delivery ntawm Steel Rail

 

 

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.
