Konbyen kalite ray lou ki genyen?
Ki sa ki tren asye?
Ray tras yo se eleman prensipal yo nan tren tren . fonksyon prensipal yo se gide wou yo nan lokomotiv ak machin pou pi devan, pote presyon an gwo nan wou yo, epi transfere li nan dormeur yo .
Nòmalman, tren asye se devi nan tren limyè, tren lou ak tren teknik .
(1) Limyè ray: 6kg/m, 9kg/m, 12kg/m, 15kg/m, 18kg/m, 22kg/m, 24k/mg, 30kg/m Materyèl: Q235b/50q/55q Longè nan chak moso: 6m ~ 12m Estanda Egzekitif: Gade nan GB 11264-89
(2) Ray lou: 38kg/m, 43kg/m, 50kg/m, 60kg/m Materyèl: U71mn/50mn/44mn longè chak moso: 12m, 12.5m estanda egzekitif: gade nan GB 2585-2007
(3) Rail Crane: QU70, QU80, QU100, QU120 Materyèl: U71MN Longè chak moso: 12m, 12.5m Estanda Egzekitif: Gade nan GB 3426-82
Sa ki anba la a se yon tab nan dimansyon ak espesifikasyon pou ray devwa lou:
| Tren asye lou | Tay | Wotè tren | Lajè anba | Lajè tèt | Epesè entènèt | Weightkg/m |
| 38kg | 134 | 114 | 68 | 13 | 38.733 | |
| 43kg | 140 | 114 | 70 | 14.5 | 44.653 | |
| 50kg | 152 | 132 | 70 | 15.5 | 51.514 | |
| 60kg | 176 | 150 | 73 | 16.5 | 60.8 | |
| 75kg | 192 | 150 | 75 | 20 | 74.64 |
Estanda nasyonalRay asye lourefer to rail products with a larger unit length weight, usually 38kg/m and above, mainly including 50kg, 60kg, 75kg and other models, which are the main rails used in China's railway trunk line transportation. This type of rail has a higher load-bearing capacity and structural stability, and is widely used in high-speed railways, passenger and freight railways, heavy-load transportation lines and coal transportation liy .
Desen an nan ray nasyonal estanda lou pa sèlman reflete nati a syantifik nan jeni mekanik estriktirèl, men tou, konfòm ak tandans nan devlopman nan gwo vitès, gwo volim ak long distans nan transpò modèn tren . Li se yon materyèl enpòtan debaz asire operasyon an ki san danje epi ki estab nan sistèm nan tren .}}
