Txheej txheem cej luam ntawm Rail Hlau
Ntsia yog lub ntsiab ntawm railway lem. Nws txoj haujlwm yog los coj cov log ntawm cov xaim ntim kom txav mus rau pem hauv ntej, dais lub siab loj ntawm lub log, thiab kis lawv mus rau lub furgers. Cov ntsia yuav tsum tau muab txuas ntxiv mus, du thiab luag yob saum npoo rau lub log. Nyob rau hauv cov hluav taws xob railways lossis cov ntu thaiv tsis siv neeg, cov ntsia kuj tseem siv tau ua raws li kev taug qab kev ncig.
Raug cov khoom siv ntawm cov hlau
Raws li hom hlau, Rail tuaj yeem faib ua peb hom:
l carbon hlau
Carbon Steel yog ib tug hlau rail smelted thiab dov nrog ntuj nyoos hlau ore. Nws tsuas yog siv cov pa roj carbon thiab manganese cov khoom hauv cov ore kom nce lub zog ntawm txoj kev tsheb nqaj hlau. Cov carbon cov pa tsheb ciav hlau taug kev hlau yog tsim ntawm 0.40% -0.80% carbon thiab manganese tsawg dua 1.30% -1.4%.
l alloy steel
Lub alleoy steel yog ib tug hlau rail uas yog smelted thiab dov tom qab cov neeg vanadium, titanium, chromium, thiab tin rau thawj hlau ore. Lub zog thiab tawv ntawm hom kev tsheb ciav hlau tseem siab tshaj li ntawm cov hlau tsheb ciav hlau.
l kub-kho steel
Cov hlau kub-kho cov hlau yog ib qho kev tsheb nqaj hlau hlau uas tau tsim los ntawm cua sov thiab tswj cov cua txias ntawm cov tsheb ciav hlau kub los yog cov tsheb ciav hlau. Cov Pearlite qauv ntawm cov tsheb ciav hlau tshav kub yog ntau dua cov kev tsheb ciav hlau ntau dua li qhov kub ntawm lub zog kub, ua rau muaj zog dua thiab tawv. Lub Hardenen Rail tom qab kev kho cua sov muaj ib txheej ntawm kev ua kom tawv tawv ntawm lub taub hau ntawm lub taub hau cov khoom siv kom cov kev pabcuam lub neej ntawm kev tsheb ciav hlau tuaj yeem txuas ntxiv.
