1. Dab tsi yog metallurgical muaj pes tsawg leeg ntawm premium-qib spikes?
Premium spikes muaj:
0.45-0.55% Cov pa roj carbonrau hardness
1.0-1.2% manganese yog 'rau toughness
0.25% Vanadium yog 'rau grain refinement
<0.04% Phosphorus/Sulfurimpurities
Qhov no muaj pes tsawg leeg ua tiav 350-400 HB hardness thaum tswj 15% elongation.
2. Yuav ua li cas spike installation rog sib txawv raws li lub hnub nyoog khi?
Ntsuas tsav tsis kam:
Tshiab hardwood ties:18-22 kN
5- xyoo muaj kev sib raug zoo:12-15 kN
Decayed ties: <8 kN
Yuav tsum tau kho lub zog rauj kom tsis txhob sib cais.
3. Dab tsi yog qhov tshwj xeeb rau Frost -resistant spikes?
Arctic - qib spikes feature:
Nickel{0}} alloyed hlau(2.5-3.5% Nis)
Sub{0}}zero temperingntawm -70 degree
Rounded shank tswv yimtiv thaiv dej khov tawg
Wax- cov xov impregnatedrau ntsia hlau spikes
Nrog -60℃tsis muaj brittleness.
4. Yuav ua li cas yog qhov kev ua tau zoo ntawm cov qauv kev suav nrog?
Finite Element Analysis (FEA) ntsuas:
Kev nyuaj siab concentrationntawm lub taub hau -shank junction
Kev vibration homnyob rau hauv 20-200Hz loading
Corrosion qhov loj hlobtshaj 10-xyoo lub voj voog
Validated nrog teb strain gauge ntsuas.
5. Dab tsi yog cov txheej txheem kev saib xyuas rau cov cuab yeej cuab tam railways?
Rau historic khiav:
Tes -forged replica spikesphim cov qub
Lub caij rov- tsav tsheb(caij nplooj ntoos hlav / caij nplooj zeeg)
Linseed roj kev kho mobntawm spike qhov
Qhov siab tshaj 25 km / htxwv ceev
Cov txheej txheem khaws cia txwv cov khoom siv niaj hnub no.
