A hlau railyog ib qho nyuaj, zoo li tus neeg taug qab steel uas tsim txoj hauv kev ntawm lub cev uas lub log steel yob, tswj kev taw qhia thaum coj tus ncej ntsug, sab nraub qaum, thiab ntev lub zog tsim los ntawm kev txav tsheb. Nws txoj haujlwm yog ua kom cov tsheb nyob hauv txoj hauv kev ruaj khov thaum xa cov khoom thauj kom nyab xeeb rau cov neeg pw tsaug zog thiab cov hauv paus.
GNEE RAILmuab cov kev tsheb ciav hlau nyob rau hauv tag nrho cov qauv xws li GB lub teeb rails thiab hnyav rails los ntawm 8-60 kg / m, UIC50, UIC54, UIC60, DIN536 crane rails A55, A65, A75, A100, A120, QU70, QU80, QU100, QU150G, AS1085 31KG–89KG, BS11: 1985 ntu, thiab AREMA/ASCE 25–175 lb, thiab tseem muab cov kev tsheb nqaj hlau txiav, drilling, thiab fastening system mov.
Cov khoom siv dab tsi yog ua los ntawm cov hlau?
Cov kab tsheb ciav hlau feem ntau yog ua los ntawm siab- carbon steel, tshwj xeeb yog tsim los tiv thaiv kev thauj khoom siab heev, rov ua dua lub log, thiab ntev - lub sij hawm qaug zog. Hom hlau no tsis yog cov qauv hlau zoo tib yam; nws yog pearlitic rail hlau tsim los muab qhov zoo sib npaug ntawm hardness, lub zog, hnav tsis kam, thiab toughness.
Los ntawm kev xav metallurgical, feem ntau cov ntsia hlau yog tsim los ntawm carbon-manganese steels nrog cov ntsiab lus carbon feem ntau nyob ib ncig ntawm 0.6-0.8%, ua ke nrog manganese los txhim kho hardenability thiab tiv thaiv tawg. Lub pearlitic microstructure muab cov ntsia hlau ua haujlwm siab rau dov kev sib cuag qaug zog thiab nto hnav, uas yog cov hom tsis ua haujlwm tseem ceeb hauv kev tsheb ciav hlau thiab crane kev tsheb nqaj hlau.
Common International rail steel qib muaj xws li:
- Nyob rau Suav thiab Esxias kev lag luam: U71Mn thiab U75V, qhov twg cov pa roj carbon ntau dua thiab cov hlau txuas ntxiv ua rau muaj zog thiab hnav tsis kam.
