Cov hlau rails yeej ib txwm nyob rau hauv ib qho chaw inconspicuous rau lub tsheb ciav hlau mus tsoo thiab coj lub tsheb ciav hlau. Niaj hnub nimno steel rail yog ua los ntawm steel. Rails tsis zoo li no thaum pib ntawm lawv yug los, lossis txawm tias cov khoom siv tam sim no. Thaum xub thawj nws yog ib daim ntawm cov ntoo square, thiab tom qab ntawd cov ntoo tau npog nrog hlau qhwv. Raws li qhov ceev thiab qhov hnyav ntawm lub tsheb ciav hlau nce, cov khoom ntawm cov ntsia hlau ua steel kauj ruam yog kauj ruam. Niaj hnub no, nrog rau kev nce ntawm lub tsheb ciav hlau ceev thiab lub luj tshib, kev txhim kho cov kev xav tau ntawm kev ruaj ntseg, kev txhim kho kev tsim khoom thiab kev tsim cov txheej txheem, kev faib tawm ntawm cov tsheb ciav hlau tau dhau los ua cov ncauj lus kom ntxaws.
Cov tshuaj muaj pes tsawg leeg ntawm tsheb ciav hlau khiav steel
| 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. |
Lub ntsiab kev puas tsuaj ntawm kev tsheb ciav hlau hlau
Sab hnav ntawm lub Upper strand thiab crushing ntawm lub qis strand.
Lub nthwv dej hnav tshwm sim los ntawm lub zog tawm los tsis txaus.
Cov pob txha tawg, spalling, ntog blocks, rail head-splitting, thiab weld tawg los ntawm tsawg toughness thiab plasticity.
Yog li ntawd, cov kev cai yooj yim rau kev tsheb ciav hlau muaj xws li: hnav tsis kam, tsoo tsis kam, nkig tawg ua haujlwm, qaug zog ua haujlwm, thiab zoo weldability.
Cov kev xav tau rau High Quality Steel Rail yog raws li hauv qab no.
Lub tsheb ciav hlau yuav tsum muaj qhov kev lag luam zoo tshaj plaws nrog lub zog, nruj, thiab kav ntev.
Qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm txoj kev tsheb ciav hlau yuav tsum zoo dua nyob ze rau nruab nrab qhov siab ntawm txoj kev tsheb ciav hlau kom lub siab tshaj plaws tensile thiab compressive stresses sib npaug.
Yuav tsum muaj kev lag luam thiab sib npaug ntawm cov hlau hauv qhov sib txawv ntawm txoj kev tsheb ciav hlau kom lawv txhua tus tuaj yeem ua tiav nws cov kev xav tau kom raug.
