Rail Fishplate Fastening System
Lub Rail Fishplate yog qhov tseeb -forged steel txuas txuas uas txuas qhov sib txawv ntawm qhov sib txuas ntawm cov tsheb ciav hlau uas nyob ib sab, ua haujlwm ib ntus lossis ruaj khov splice. Tsis zoo li cov welded rail txuas txuas ntxiv, cov pob qij txha pob txha tsim ib qho kev sib txuas uas tso cai rau kev tswj xyuas ntsug deflection thaum tswj kev sib dhos kab rov tav. Lub phaj lub moos moos -zoo li tus ntoo khaub lig- ntu yog tsim los ua kom haum rau txoj kev tsheb ciav hlau qhov nruab nrab ntawm qhov nruab nrab, kom ntseeg tau tias khoov kev ntxhov siab hloov pauv tau zoo thoob plaws qhov sib koom ua ke. Tsim los ntawm kub dov los yog poob forging los ntawm manganese los yog carbon steels, cov phaj no haum rau thermal expansion thaum txhawb lub log loads xws li lub teeb rail mus rau hnyav -haul lub ntsiab kab .
Technical Specifications:
| Feature Qeb | Cov txiaj ntsig tseem ceeb | Daim Ntawv Thov Kev Sib Tham |
|---|---|---|
| Manganese hlau | Ua haujlwm- nyuaj rau kev cuam tshuam rau lub neej ntev | Heavy-haul & impact zones |
| Grain Flow Orientation | Matched rau bending stress direction | High -cov kab ceev ceev |
| Bolt Qhov Clearance | Haum 10-15mm thermal txav | Kub- huab cua hloov pauv |
| 45℃Crack Detection | Thaum ntxov tsis ua tiav qhov kev txheeb xyuas | Kev soj ntsuam ib txwm |
| Tso-Forged Grain | Superior fatigue resistance vs. dov | Turnouts & hla pob zeb diamond |
| Expansion Joint Design | Tswj cov thermal zog heev | Ntev welded rail ntu |
Installation & Maintenance Perspective:
- Kub- dov daim hlau nthuav tawm cov nplej tsis tu ncua raws li qhov bar profile rau kev txhim kho kev qaug zog.
- Tso-forged versions feature superior grain orientation perpendicular rau dabtsi yog khoov stresses .
- Manganese steel qib (12-14% Mn) muab cov khoom ua haujlwm hnyav hauv kev cuam tshuam kev thauj khoom .
- Normalizing tshav kub kho refines grain qauv tom qab tsim, tshem tawm residual stresses.
- Nto decarburization tswj kom tsawg dua 0.5mm kom tswj tau qhov tawv tawv thiab hnav tsis kam.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Fishplates yuav tsum haum rau kev nthuav dav ntawm 0.0115mm ib meter ib℃Celsius.
- Bolt qhov clearances xam kom tso cai 10-15mm ntawm longitudinal txav ntawm huab kub.
- Kev saib xyuas qhov sib txawv raws caij nyoog yuav tsum tau tiv thaiv "knuckle rail" deformation nyob rau lub caij ntuj sov.
- Lub caij ntuj no contraction tuaj yeem qhib qhov khoob dhau ntawm lub phaj muaj peev xwm, ua rau siab - cuam tshuam lub log .
- Kev nthuav dav cov pob qij txha nrog zawv zawg fishplates siv qhov twg thermal txav tshaj tus qauv muaj peev xwm.
