Lub ntsiab lus ntawm txoj kev tsheb ciav hlau yog dab tsi?
Ib txoj kev tsheb ciav hlau (los yog kev tsheb ciav hlau / kev tsheb ciav hlau) yog txoj hauv kev tsim rau cov tsheb ciav hlau, muaj ob qho tib si steel rails ntawm cov neeg pw tsaug zog (kev sib txuas) thiab ballast, muab qhov qis - txhuam qhov chaw rau cov log kom yob rau kev nyab xeeb, kev thauj mus los. Nws yog lub hauv paus infrastructure, suav nrog kev tsheb ciav hlau, fastenings, sleepers, thiab ballast, uas tso cai rau cov tsheb ciav hlau mus ncig thiab txiav txim siab lawv txoj kev ceev thiab kev ua tau zoo, tsim "txoj kev mus tas li" rau kev tsheb ciav hlau.
Cov ntsiab lus tseem ceeb & lub ntsiab lus:
- Rails: Cov hlau tuav ncaj qha rau hauv kev sib cuag nrog lub tsheb ciav hlau lub log.
GNEE RAIL muaj nyob rau hauv kev tsim steel rails ntawm ntau yam qauv siv nyob rau hauv thee mining, lub ntsiab railway kab, factories, cranes, thiab lwm yam. Muaj lub teeb steel rails, hnyav steel rails, crane steel rails, thiab tshaj hnyav steel rail.

- Sleepers/Ties: Hla- kab teeb (ntoo, pob zeb) uas tuav cov hlua ntawm qhov sib nrug deb.
- Ballast: Crushed pob zeb hauv paus uas txhawb cov neeg pw tsaug zog thiab faib qhov hnyav.
- Lub Hom Phiaj: Los coj cov tsheb ciav hlau, muab kev ruaj ntseg, thiab ua kom muaj zog txav mus ntev.
GB Rail vs UIC Rail
Tuam Tshoj tus GB (Guobiao) cov qauv kev tsheb ciav hlau thiab UIC (International Union of Railways) cov qauv sib txawv feem ntau hauv lawv qhov kev tsom xam: GB rails feem ntau ua qhov tseem ceeb rau kev hnav tsis kam rau hnyav hnyav / kev kub ceev uas siv tshwj xeeb siab -manganese steels (xws li U71Mn, U75V) rau Tuam Tshoj tus loj heev UIC UIC qauv (UIC), thaum lub sij hawm sib npaug UIC, toughness, weldability, thiab purity nrog nruab nrab -carbon steels (C45E, R350HT) rau European interoperability, txawm hais tias ob leeg muaj siab - zog xaiv thiab ntau profiles xws li UIC60/GB60kg.

Cov kev sib txawv tseem ceeb yog nyob rau hauv cov khoom muaj pes tsawg leeg, kev kho cua sov, ntev ntev (GB feem ntau 25m, UIC 12-25m), thiab kev ntsuas kev ua tau zoo, txawm tias ob qho tib si tsom rau kev nyab xeeb thiab kev ua haujlwm.
