Rail SKL Spike Fastening System
CovSKL clipyog ib tug precision -engineered omega-zoo li tus (Ω) nro clamp uas ua hauj lwm raws li lub elastic fastening caij nyob rau hauv niaj hnub railway khiav systems, tsim los ntawm siab-qib caij nplooj ntoos hlav steel alloys xws li 60Si2CrA, 60Si2MnA, thiab 38Si7 nrog carbon ntsiab lus ntawm 0.54% zoo rau lub caij nplooj ntoos hlav. Cov clips no ua tiav los ntawm -hardness ntawm 42-47 HRC los ntawm cov roj quenching thiab tempering ntawm 420-480 degree, xa lub zog tensile ntawm 1,400-1,700 MPa thiab yield zog tshaj 1,100 MPa nyob ntawm kev xaiv alloy .

Installation & Maintenance Perspective:
- Alloy-Kev siv tshwj xeeb:60Si2CrA (chromium-alloyed) muab kev tiv thaiv kev qaug zog rau hnyav- txoj hauv kev; 60Si2MnA (manganese-alloyed) muaj cov khoom sib npaug rau cov neeg caij tsheb loj; 38Si7 muab cov tawv tawv zoo tshaj plaws rau kev siv txias- cheeb tsam; thiab 55Si2Mn muab tus nqi- ua haujlwm tau zoo rau cov kab thib ob .
- Precision carbon tswj:Cov ntsiab lus carbon khaws cia ntawm 0.54-0.64% nrog ± 0.02% kam rau ua kom zoo ib yam hardenability thiab martensitic transformation thaum lub sij hawm quenching, ua tiav lub hom phiaj hardness ntawm 42-47 HRC nyob rau hauv tag nrho cov khoom batches.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Static Proof Load Testing:Cov qauv tsim tau dhau los ntawm 20-30 kN static load daim ntawv thov rau 60 vib nas this, nrog rau kev ntsuas mus tas li thiab txwv tsis pub tsawg dua lossis sib npaug li 0.5 hli txhawm rau txheeb xyuas tus cwj pwm elastic hauv kev txwv tsim.
- Siab -Cycle Fatigue Validation:Cov neeg sawv cev clips tau sim rau 5-7 lab lub voj voog ntawm 80-90% ntawm qhov ua haujlwm siab tshaj plaws (EN 13146-7), nrog rau kev tshuaj xyuas ultrasonic ntawm 1-million-cycle intervals txhawm rau txheeb xyuas qhov pib tawg ua ntej tshaj tawm .
- Load-Deflection Curve Characterization:Txhua pawg ntau lawm suav nrog cov qauv kuaj ntawm cov ntsuas ntsuas uas tsim kom muaj zog ua tiav -deflection curves, xyuas kom meej tias clamping quab yuam poob rau hauv cov kab siab ntev (± 8% ntawm nominal).
