1. Cov ntaub ntawv spike txawv li cas thoob ntiaj teb?
North America:AISI 1045 carbon hlau
Teb chaws Europe:EN8D nruab nrab carbon steel
High - kab ceev:35CrMo alloy hlau
Tuam Tshoj siv Q235B steel nrog tsawg lub ntiaj teb additives rau corrosion kuj.
2. Dab tsi yog lub luag haujlwm ntawm cov tshuab ntxhua khaub ncaws?
Cov tshuab ntxhua khaub ncaws:
Faib loadtiv thaiv lub taub hau embedment
Muab rwb thaiv tsevnyob rau hauv hluav taws xob lem
Ua kom them nyiaj rau qhov tsis sib xws
Thickness ranges 4-6mm nyob ntawm cov khoom khi.
3. Yuav tshuaj xyuas li cas thaum kuaj xyuas?
Kev soj ntsuam xyuas:
Rub - tawm tsis kam (>3kN rau dev spikes)
Lub taub hau qhov siab(max 2mm saum khi)
Corrosion theem (<20% surface rust)
Lub kaum sab xis(± 5℃los ntawm kev teeb tsa)
4. Vim li cas qee qhov spikes offset los ntawm rail centerline?
Offsetting (10-15mm) pab:
Counter lateral rogntawm nkhaus
Sib npaug hnavnruab nrab ntawm spike khub
Ua kom dav dav footed rails
Alignment raws li rail cant lub kaum sab xis.
5. Dab tsi yog keeb kwm ntawm spike rauj tsim?
Evolution ncua sij hawm:
1860s:3kg tes rauj
1920s:Trip- rauj rau cov neeg laib
1960s:Pneumatic spike tsav tsheb
2020s:Automated robotic tsav tsheb
