A steel railua raws li cov qauv thauj khoom- hloov nruab nrab ntawm cov khoom siv dov thiab lub hauv paus khiav, dispersing log siab los ntawm nws tus ntoo khaub lig-section mus rau hauv pw tsaug zog thiab subgrade cov ntaub ntawv. Nws txoj kev khoov khov kho thiab kev ruaj ntseg sab nraud yog qhov tseem ceeb rau kev tiv thaiv kev tsheb nqaj hlau hla thiab taug qab cov duab geometry distortion, tshwj xeeb tshaj yog nyob rau hauv nkhaus thiab hauv qab eccentric log loads.
GNEE RAILmuab tag nrho -ntau txoj kev tsheb ciav hlau rau txoj kab ncaj nraim, nkhaus, thiab qhov chaw tig tawm, muab cov khoom siv rau hauv qhov ntev thiab qhov ntev, thiab muaj cov kev pabcuam prefabrication nrog rau kev sib dhos nkhaus, drilling thiab lwm yam.
Dab tsi yog steel rails ua los ntawm?
Rails yog ua los ntawmtshwj xeeb siab - carbon steel, feem ntau hu uarail hlau, uas yog engineered los muab siab zog, hnav tsis kam, thiab qaug zog lub neej nyob rau hauv rov qab log loads. Tsis zoo li cov qauv hlau, rail steel yog optimized raudov kev sib cuag, tsis yog rau kev tsim kho.
Los ntawm cov tshuaj muaj pes tsawg leeg foundations, feem ntau railway thiab crane rails sivcarbon-manganese hlaunrog cov ntsiab lus carbon feem ntau nruab nrab ntawm0.6% thiab 0.8%, ua ke nrog tswj qib ntawm manganese, silicon, thiab qee zaum micro-alloying ntsiab xws li vanadium los yog chromium. Qhov muaj pes tsawg leeg no tso cai rau lub taub hau tsheb ciav hlau kom ua tiav qhov siab tawv tom qab dov lossis kev kho cua sov, thaum lub vev xaib thiab ko taw khaws cov toughness txaus los tiv thaiv kev tawg thiab cuam tshuam.
- Nyob rau hauv Suav thiab ntau lub thoob ntiaj teb export tej yaam num, ib tug heev rail khoom sivua 71mn, uas txhais tau hais tias kwv yees0.71% carbon nrog manganese alloying. U71Mn muaj qhov sib npaug zoo ntawm hardness thiab weldability, ua rau nws siv dav rau cov kev tsheb ciav hlau loj, kev lag luam sab hauv, thiab tseem raucrane rail daim ntaub ntawv qhov chaw siab durability yuav tsum tau. Rau qhov hnyav dua lossis hnyav dua hnav ib puag ncig, hloov kho qib xws liU75V(vanadium-alloyed) yog siv los txhim kho kev qaug zog thiab hnav tsis kam.
