Dab tsi yog cov tsheb ciav hlau ua los ntawm?
Jan 21, 2026
Hlau railyog lub hauv paus txheej txheem ntawm ib qho kev tsheb ciav hlau -raws li kev thauj mus los lossis kev tuav, lub luag haujlwm rau kev coj lub log, nqa ntsug thiab sab nraub qaum, thiab tuav ntev - lub sijhawm taug qab geometry. Nrog nws lub taub hau optimized-web-base cross-section, txoj kev tsheb ciav hlau hloov lub log quab yuam rau hauv pw tsaug zog, ballast, los yog steel beams thaum tiv thaiv bending qaug zog thiab nto hnav.
Hauv cov haujlwm tiag tiag, cov tsheb ciav hlau tsis yog tsim los ntawm ib qho khoom siv thoob ntiaj teb. Hloov chaw, cov qib steel sib txawv raug xaiv kom haum rau cov qauv kev tsheb ciav hlau sib txawv thiab cov qauv tsheb ciav hlau xws li UIC60, 60E1, 75kg, 132RE, CR100, thiab BS113A. Cov khoom siv no-profile pairing yog qhov txiav txim siab txog kev pabcuam lub neej, kev saib xyuas lub sijhawm, thiab kev sib raug zoo nrog cov tshuab fastening.
Dab tsi yog cov tsheb ciav hlau ua los ntawm?
Cov tsheb ciav hlau feem ntau yog tsim los ntawm nruab nrab - mus rau siab - carbon steels nrog manganese lossis vanadium alloying los txhim kho lub zog thiab hnav tsis kam. Cov qib sib txawv yog siv rau qib sib txawv ntawm kev siv tsheb.
