A tren asyese yon enjenyè manm portant-chaj ki gide machin yo pandan y ap diminye usure, vibrasyon, ak risk pou yo deraye. Konpozisyon métallurgique li, -seksyon transvèsal li, ak dite li yo detèmine rezistans alontèm ak fyab operasyon.GNEE RAILfouni ray asye nan tout estanda prensipal yo, ki gen ladan ray limyè / lou GB, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS1085 31–89 kg, BS11:1985, ak AREMA, konplemantè, koupe l25–ASCE tretman chalè, ak pwojè-sipò teknik espesifik.
Ki kalite ray komen yo ye?
Rail asye komen yo klase prensipalman pa pwa nan ray lou (pi gran pase oswa egal a 43kg / m) pou liy prensipal, ray limyè (<43kg/m) for industrial/mining lines, and crane rails (QU series) for heavy-duty lifting. Most common rails are flat-bottomed (Vignoles) made from carbon-manganese steel, with specialized types including heat-treated and alloy rails.
Klasifikasyon kle nan tren asye komen
Pa pwa ak itilizasyon:
- Rail lou (43kg/m, 50kg/m, 60kg/m, 115RE, 136RE): Yo itilize pou liy prensipal tren nasyonal yo ak gwo -vitès tren, ki fèt pou okipe gwo vitès ak gwo trafik.
| Klasifikasyon | Wotè (mm) | Tèt (mm) | Anba (mm) | Epè (mm) | Pwa (kg/m) | |

| 60 KG/M | 176 | 73 | 150 | 16.5 | 60.64 | |
- Rail limyè (9kg, 12kg, 15kg, 22kg, 30kg): Prensipalman itilize pou min, forè, ak liy transpò tanporè.

| 30 KG/M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
- Rail teknik (QU70, QU80, QU100, QU120): Karakterize pa yon tèt pi laj ak pi epè entènèt pou okipe gwo -presyon vètikal ki soti nan wou chariot teknik.
| Klasifikasyon | Wotè (mm) | Tèt (mm) | Anba (mm) | Epè (mm) | Pwa (kg/m) | |

Pa materyèl ak tretman chalè:
- Kabòn-Manganèz Steel: Materyèl estanda, ak 0.6%-1.2% kabòn pou dite ak 0.8%-1.7% Manganèz pou severite.
- Tèt-Rail fè tèt di: Espesyalman chalè-trete sou tèt tèt la pou ogmante rezistans mete nan gwo-trafik oswa seksyon koube.
- Rail alyaj: Gen eleman ajoute tankou chromium oswa Silisyòm pou kondisyon chaj ekstrèm.
