Dab tsi yog qhov txawv ntawm steel rails?
Steel rails yog categorized los ntawm profile (xws li Vignoles / Pav ca-Kab qab, Grooved rau trams, Crane Rails), qhov hnyav / daim ntawv thov (Lub teeb, Hnyav, Crane), thiab steel muaj pes tsawg leeg / kho (Carbon, Alloy, Lub taub hau-Hardened, Thaum tshav kub kub-Kho), kev sib txawv, kev sib txawv thiab kev sib txawv I-beams rau tsheb ciav hlau thiab cov duab grooved rau trams, thaum cov khoom sib txawv ntawm cov pa roj carbon monoxide mus rau qib siab qis- alloys rau durability.
Los ntawm Profile & Application
- Vignoles Rails (Pov-Kab): Feem ntau, asymmetrical I-beam duab nrog lub hauv paus dav, siv rau cov qauv tsheb ciav hlau.
- Grooved Rails: Feature ib zawj rau lub log flanges, siv rau trams thiab streetcars.
