Rails yog kub dov los ntawm tsis tu ncua cam khwb cia blooms los yog rounds muaj qhov tsim nyog cross-section rau cov ntsia hlau yuav tsum tau ua. Lawv kuj tuaj yeem raug dov los ntawm qhov ze-net zoo nruam nruam rails, uas txuag lub sij hawm, lub zog, thiab tus nqi los ntawm kev txo cov kev ua haujlwm uas xav tau kom tau txais txoj kev tsheb ciav hlau mus rau nws qhov kawg.
Steel Rails yog qhov tseem ceeb ntawm txoj kev tsheb ciav hlau tau muab tso rau hauv ob txoj kab sib txuas kom muab qhov txuas mus tas li, ruaj khov thiab theem saum npoo rau kev khiav tsheb ciav hlau. Lub tsheb ciav hlau hnyav thiab ceev ceev yuav tsum tau ua kom siab dua kom tiv taus kev ntxhov siab, yog li lawv tau tsim los ntawm cov pa roj carbon siab (carbon {{0}}}.6% rau 0.8 %, manganese 0} .8%-1.3%, silicon 0.1% {{10}}.5%, sulfur thiab phosphorus 0.03% siab tshaj txhua, thiab txhuas 0.015% siab tshaj). Qee qib ntawm cov hlau muaj chromium (Cr{16}}.8% rau 1.2%). Hlau Rails kuj yog tsim los ntawm cov hlau tshwj xeeb uas muaj niobium (Nb- 0.04 % max.) lossis vanadium (V-0.2% max.). Hauv cov xwm txheej fierece steel rails yuav tsum tau tsim los ntawm corrosion resistant steels kuj tau tsim.
| Tsis muaj. | Element | Muaj nuj nqi |
| 1 | C | Txhim kho lub zog, hardness, thiab hnav tsis kam ntawm txoj kev tsheb ciav hlau. Cov ntsiab lus carbon ntawm cov tsheb ciav hlau hauv tsev yog {{0}}.65% rau 0.82%. |
| 2 | Si | Nws yog ib qho yooj yim los ua ke nrog oxidation, thiab tuaj yeem ua lub luag haujlwm ntawm kev tshem tawm npuas hauv cov hlau. Cov hlau muaj qhov tsim nyog ntawm silicon, uas tuaj yeem txhim kho hardness thiab hnav tsis kam ntawm cov hlau. |
| 3 | Mn | Nws yog ib qho txiaj ntsig zoo uas tuaj yeem txhim kho lub zog thiab hnav tsis kam ntawm cov hlau thiab ua rau kom muaj zog ntawm cov hlau. Nws tuaj yeem tshem tawm cov teeb meem hlau oxide thiab sulfide inclusions hauv cov hlau. |
| 4 | Cu | Nws yog ib qho txiaj ntsig zoo. Cov hlau muaj cov tooj liab me me, uas tuaj yeem txhim kho qhov qaug zog thiab corrosion tsis kam ntawm cov hlau. |
| 5 | P | Nws yog ib qho teeb meem. Qhov phom sij loj tshaj plaws ntawm phosphide yog txo cov plasticity thiab toughness ntawm cov hlau. |
| 6 | S | Cov sulfur yog ib qho teeb meem. Nws feem ntau yog nyob rau hauv cov hlau nyob rau hauv daim ntawv ntawm granules. |
Steel Rail Lub luag haujlwm hauv Railtrack System
Steel rail yog qhov tseem ceeb tshaj plaws nyob rau hauv txoj kev tsheb ciav hlau, nws yog steel profile nrog cov duab ntawm inverted T. Ntau yam steel rails yog tsim nrog qhov sib txawv ntawm qhov hnyav thiab qhov ntev. Txhua hom Steel Rail muaj lub taub hau tawv thiab tiaj tus hauv qab. Qhov tshwj xeeb zoo li no yog tsim los nrog ib pawg ntawm cov tsheb ciav hlau fastening qhov chaw uas txhim kho steel rail ntawm rail sleepers: Rail Spike, Screw Spike, Elastic Rail Clip, Rail Clamp, thiab lwm yam.
