Steel Rail Txheej txheem cej luam
Cov hlua hlau yog qhov tseem ceeb ntawm cov tshuab tsheb ciav hlau, muab cov chaw ruaj khov rau saum npoo rau cov tsheb ciav hlau los khiav. Cov hlua hlau hlau tau sib xyaw raws li cov khoom muaj pes tsawg leeg, cov neeg kho tshuab, hnyav, thiab ntev. Peb yog ib qho kev tshaj lij thiab txhim khu kev qha cov chaw tsim khoom ntawm cov hlua hlau hlau, ua ntau cov hlua hlau uas tau raws li cov qauv haujlwm thoob ntiaj teb. Peb muab kev txhawb nqa kev pabcuam thiab cov kev pabcuam, thiab tseem tuaj yeem muab cov kev daws teeb meem raws li cov neeg siv khoom. Tiv tauj peb kom paub cov ntaub ntawv ntau ntxiv.
Kev faib tawm ntawm Railway Rails hauv Suav teb
Kev faib tawm ntawm railway rails tam sim no tsim los ntawm peb yog raws li nram no:
Hom Stack:
Carbon Rails: Cov no feem ntau yog tsim los ntawm kev ntxiv carbon (C) thiab manganese (Mn) los txhim kho lub zog thiab tawv, xws li U71Mn, AP1, thiab U74.
Alloy Rails: Raws li cov pa roj carbon rails, alloy rails ntxiv cov ntsiab lus xws li vanadium (V), titanium (Ti), chromium (Cr), thiab molybdenum (Mo) los txhim kho lub zog thiab tawv, xws li PD1, PD3, thiab V-Ti txoj hlua.
Thaum tshav kub kub kho Rails: Cov no yog cov pa roj carbon rails uas dhau los ua cua sov thiab tswj cov cua txias kom txhim kho lawv cov qauv hlau, ua rau muaj zog thiab tawv, xws li PD2.
Los ntawm Rail ceeb thawj:
38kg / m (P38)
43 KG / M (P43)
45 kg / m (p45)
50kg / m (P50)
60kg / m (P60)
75kg / m (P75)
Los ntawm Mechanical Properties:
Standard Rails: Cov no muaj lub zog tensile tsis tsawg tshaj 800 MPa.
High-Strength Rails: Cov no muaj lub zog tensile tsis tsawg dua 900 MPa.
Wear-Resistant Rails: Cov no muaj lub zog tensile tsis tsawg dua 1100 MPa.
Rail ntev:
12.5 m, 25 m, 75 m, thiab 100 m. Tam sim no, 25 m kev sib tw yog feem ntau ua.
