136RE Rail Nyhav Ib Meter npaum li cas?
Cov136 RE RAWSmuaj qhov hnyav ntawm kwv yees67,56kg ib. Qhov no yog muab los ntawm nws tus qauv hnyav ntawm136.2 lbs ib yard. Hauv kev lag luam tsheb ciav hlau, qhov hnyav no tau muab faib ua "hnyav-haul," muab cov txheej txheem loj uas xav tau rau Class I freight railroads thiab siab -tonnage thauj.
1. Cov qauv hloov dua siab tshiab
Rail hnyav nyob rau hauv North America feem ntau yog qhia raws li lb / yd (Wlb), thaum thoob ntiaj teb kev lag luam siv kg / m (Wkg ). Lub conversion yog xam raws li nram no:
- Wkg =Wlb × 0.49606
- Rau 136RE profile: 136.2 × 0.49606=67.563 kg/m
2. Lub cev qhov hnyav rau qhov hnyav
Qhov hnyav ib 'meter' yog ib qho txiaj ntsig ncaj qha ntawm txoj kev tsheb ciav hlau hla -sectional geometry. 136RE yog tsim los nrog cov hlau loj heev los daws cov kev ntxhov siab loj:
- Hla -Sectional Area: 13.32 in2 (kwv yees . 85.94 cm2).
- Hlau ntom: Raws li tus qauv ceev ntawm cov hlau rail (kwv yees . 7,850 kg / m3), qhov tshwm sim loj yog faib rau lub taub hau thiab lub hauv paus kom ruaj khov siab tshaj plaws.
Dab tsi yog tus qauv qhov ntev ntawm 136RE Rail?
136RE (tseem hu ua TR68) yog AREMA tus qauv rail profile nrog tus qauv qhov siab ntawm 185.74 hli, lub hauv paus dav ntawm 152.4 hli, lub taub hau dav ntawm 74.61 hli, thiab lub web thickness ntawm 17.46 hli. Nws hnyav kwv yees li 67.41–67.5 kg / m thiab feem ntau yog siv rau hnyav-lub luag haujlwm, siab- qag- thauj khoom.
Ntsiab 136RE Rail Dimensions thiab Specifications (raws li AREMA qauv):
- Rail Qhov siab: 185.74mm (7-5/16 nyob rau hauv)
- Base dav: 152.4mm (6 nyob rau hauv)

136RE rail yog tsim los rau kev ruaj ntseg thiab hnav tsis kam, feem ntau siv rau hauv hnyav -cov kab tsheb ciav hlau thiab cov chaw thauj khoom thauj.
Dab tsi yog cov khoom ntawm 136 lb rail?
136RE rail yog ua los ntawm siab -carbon manganese steel, ua los ntawm "tua hlau" txheej txheem los xyuas kom meej qhov siab tshaj plaws thiab purity. Cov tshuaj muaj pes tsawg leeg feem ntau suav nrog 0.72% mus rau 0.82% Carbon rau hardness thiab 0.70% rau 1.10% Manganese rau toughness thiab hnav tsis kam. Nyob ntawm daim ntawv thov, nws muaj nyob rau hauv Standard Strength (SS) lossis Lub Taub Hau Hardened (HH) qib, nrog rau tom kawg tau txais kev kho cua sov kom ncav cuag Brinell hardness ntawm 370 txog 400 HBW.
