Rail thiab Spike Fastening System
CovRailway E-Clipyog ib tug precision- tsim lub caij nplooj ntoos hlav steel fastening tivthaiv tus yam ntxwv los ntawm nws txawv "E" silhouette, engineered los muab resilient rail restraint los ntawm kev tswj elastic deflection thoob plaws peb load- bearing cov ntsiab lus. Tsim los ntawm siab -kev ua tau zoo caij nplooj ntoos hlav steel alloys suav nrog 60Si2MnA, 55Si7, thiab Ck67 (DIN 17222) nrog cov ntsiab lus carbon ntawm 0.55-0.70%, cov clips no ua tiav los ntawm-hardness ntawm 41-46 HRC ntawm roj 40420℃thiab tempering. Lub E-zoo li tus geometry tsim muaj ntau-theem caij nplooj ntoos hlav mechanism uas lub hauv paus koov tsim thawj clamping quab yuam (feem ntau 7-12 kN) thaum ob sab caj npab muab lateral stability thiab rotational resistance.

Installation & Maintenance Perspective:
- Elastic Hysteresis Zog poob:Nyob rau hauv cyclic loading, sab hauv cov khoom damping dissipates 5-8% ntawm cov tswv yim zog raws li cua sov, txo dynamic loads xa mus rau sleepers los ntawm 15-20% piv rau nruj fastenings.
- Rov qab Precision:Tom qab 5 lab deflection cycles, cov txheej txheem ruaj khov tseem qis dua 0.3mm, kom ntseeg tau tias qhov tseem ceeb clamping geometry yog khaws cia thoob plaws lub neej kev pabcuam.
- Impact Energy Absorption:Nyob rau hauv lub log flats los yog rail pob qij txha, cov clip absorbs 30-40% ntawm lub zog cuam tshuam los ntawm ceev elastic deflection, tiv thaiv qhob pw tsaug zog los ntawm kev poob siab-induced micro- cracking .
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Sacrificial Zinc Coatings:Mechanical zinc plating (8–15µm) muab kev tiv thaiv cathodic ntawm khawb lossis txiav xaus, nrog zinc corroding nyiam rau cov hlau ntawm tus nqi ntawm 1–4µm ib xyoo nyob ntawm kev faib ib puag ncig rau ISO 9223 .
- Barrier Protection Systems:Dacromet 320 (zinc{1}}aluminium flake txheej) tsim 6-10µm lub cev thaiv kev tiv thaiv nrog 500-700 xuab moos ntsev tshuaj tiv thaiv, zoo tagnrho rau cov ntug hiav txwv dej thiab qhov chaw ib puag ncig uas muaj cov tshuaj chloride ua kom corrosion.
- Kev Tiv Thaiv Hydrogen Embrittlement: For high-strength grades (>1,200 MPa), cov txheej txheem nruj tswj txwv cov kua qaub ntxuav lub sij hawm thiab ua haujlwm ci ntawm 200℃rau 4-24 teev kom tshem tawm hydrogen absorbed thaum plating.
