Dab tsi yog qhov txawv ntawm TR68 thiab AREMA 136RE Rail?
TR68 ibAREMA 136 REfeem ntau yog tib yam hnyav -lub luag haujlwm, 136 lb/yd rail profile. "136RE" yog kev tsim qauv rau Railway Engineering (AREMA) cov qauv, thaum "TR68" feem ntau yog lub npe lag luam xa mus rau nws ~ 68 kg / m loj. Ob leeg yog tsim los rau hnyav - thauj khoom thauj, siab - kab ceev, thiab kev siv hauv kev lag luam, muab lub zog zoo dua.
Qhov tseem ceeb Commonalities thiab Differences:
- Zoo tib yam Profiles: TR68 thiab 136RE qhia tib qhov qauv geometric, qhov ntev, thiab qhov hnyav (kwv yees . 136 lbs / yd lossis 67.5 kg / m).
- Cov qauv: Ob leeg yog tsim los ua raws li American Railway Engineering thiab Maintenance- ntawm -Way Association (AREMA) Tshooj 3 cov qauv.
- Hloov pauv tau: Lawv yog cov hloov pauv tau tag nrho, lub ntsiab lus TR68 tuaj yeem siv los hloov ncaj qha rau 136RE rail.
- Terminology: 136RE yog lub npe ua haujlwm raws li qhov hnyav (136 lbs / yd), thaum TR68 feem ntau siv los piav txog tib txoj kev tsheb ciav hlau (68 kg / m) hauv cov khw tshwj xeeb.
Specifications ntawm 136 LB Rail:
Lub 136 lb/yd AREMA (136RE) rail yog siab -lub zog,67.5 kg / msteel rail tsim rau hnyav- tsheb thauj mus los, mainline tsheb, thiab kev lag luam, chaw nres nkoj, lossis mine lem. Nws yog lub npe hu ua TR68 rail nrog 185.74 mm qhov siab, 152.40 mm puag, thiab 74.61 mm lub taub hau dav. Standard ntev muaj xws li39' thiab80'.

Dab tsi yog cov khoom ntawm AREMA 136RE rail?
Cov khoom siv ntawm AREMA 136RE rail (tseem hu ua 136 lb rail lossis TR68) yog siab -cov pa roj carbon zoo, tsim nruj raws li AREMA (American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes) specifications.
Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm 136RE hnyav rail nyob rau hauv qhov xav tau ib puag ncig, cov khoom siv tau muab faib ua ntau qib raws li cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab:
1. Tshuaj muaj pes tsawg leeg
Cov hlau siv rau 136 RE steel rail feem ntau muaj cov qib tswj cov pa roj carbon, manganese, thiab silicon kom sib npaug hardness thiab toughness. Raws li tus qauv AREMA 136RE yuav tsum:
- Cov pa roj carbon (C):0.72% - 0.82% (Muab lub zog thiab hnav tsis kam)
- Manganese (Mn):0.70% - 1.10% (Txhim kho toughness thiab hardenability)
- Silicon (Si):0.10% - 0.50% (Ua raws li deoxidizer)
- Phosphorus (P) & Sulfur (S):Txwv kom tsawg dua lossis sib npaug rau 0.035% thiab Tsawg dua lossis sib npaug li 0.040% raws li kev tiv thaiv brittleness.
