Rail Dog Spike Fastening System
CovRailway Dog Spikeyog ib qho forged steel fastening tivthaiv nrog offset L-zoo li lub taub hau thiab square shank, engineered kom ruaj ntseg rails thiab khi daim hlau rau cov ntoo pw tsaug zog los ntawm kev sib cuam tshuam cov neeg kho tshuab ncaj qha. Tsim los ntawm cov qib carbon steel suav nrog Q235, 45 #, thiab 55 #, nrog cov khoom vaj khoom tsev xws li 4.6 txog 8.8, cov spikes no ua tiav lub zog tensile ntawm 400-800 MPa nyob ntawm qhov tshwj xeeb.

Installation & Maintenance Perspective:
- Cov ntaub ntawv muaj: Q235, 45 #, 55 # carbon steel nrog cov cuab yeej chav kawm 4.6, 5.6, 8.8
- AREMA siab-tensile qib: 70,000 psi (483 MPa) tensile, 46,000 psi (317 MPa) tawm los, 25% elongation
- Optimized carbon cov ntsiab lus: 0.17-0.25% nrog manganese 0.90-1.35% rau lub zog- ductility tshuav
- Txias khoov kuaj: 90℃yam tsis muaj cracking xyuas ductility rau kev tsav tsheb
- Hardness ntau yam: 85-95 HRB rau qis- cov pa roj carbon qib kom ntseeg tau cov pob txha tsis kam
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Square shank (14-16mm) muab 50% siab tuav lub zog tshaj qhov sib npaug puag ncig shanks
- Offset L-zoo li tus lub taub hau nrog nqes hav hauv qab qhov sib tw rail puag lub kaum sab xis rau kev sib tsoo
- Wedge-zoo li tus taw tes tsav hla ntoo nplej ob npaug rub- tawm qhov tsis kam tiv nrog- nplej tsav
- Ob-lug "dog-eared" lub taub hau tsim (European style) los yog diav -zoo li lub taub hau (American style)
- Rub- tawm cov ntaub ntawv tawm tsam: 857 lbs hauv cov ntoo qhuav qhuav, 4,281 lbs hauv cov ntoo qhib caij nyoog (9/16 "ntsiab)
