Txheej txheem cej luam ntawm Rail Steel
Rails yog cov khoom tseem ceeb ntawm txoj kev tsheb ciav hlau. Nws txoj haujlwm yog coj lub log ntawm cov khoom dov mus rau pem hauv ntej, dais lub siab loj ntawm lub log, thiab xa mus rau cov neeg pw tsaug zog. Cov ntsia hlau yuav tsum muab qhov txuas mus tas li, du thiab tsawg kawg rub nto rau lub log. Nyob rau hauv cov hluav taws xob railways los yog tsis siv neeg thaiv cov seem, cov ntsia hlau kuj siv tau raws li kev khiav circuits.
Yam khoom ntawm Track Steel
Raws li hom steel, rail yuav muab faib ua peb hom:
l Carbon hlau
carbon steel yog ib tug hlau rail smelted thiab dov nrog ntuj raw hlau ore. Nws tsuas yog siv cov pa roj carbon thiab manganese hauv cov ore kom muaj zog ntawm txoj kev tsheb ciav hlau. Ordinary carbon tsheb ciav hlau khiav hlau yog tsim los ntawm 0.40% -0.80% carbon thiab manganese tsawg dua 1.30% -1.4%.
l Alloy hlau
Cov hlau hlau yog cov hlau hlau uas tau smelted thiab dov tom qab ntxiv cov khoom tsim nyog ntawm cov hlau xws li vanadium, titanium, chromium, thiab tin rau cov hlau qub. Lub zog thiab tawv ntawm hom kev tsheb ciav hlau no siab dua li ntawm cov tsheb ciav hlau carbon.
l Thaum tshav kub kub kho steel
Cov cua kub-kho cov hlau yog cov hlau rail uas yog tsim los ntawm cua sov thiab tswj cov cua txias ntawm cov kub dov carbon rail lossis alloy rail. Lub pearlite qauv ntawm lub tshav kub-kho rail yog ntau refined dua li ntawm cov kub dov rail, uas ua rau muaj zog dua thiab toughness. Lub hardened rail tom qab kev kho cua sov muaj ib txheej ntawm hardening kho ntawm lub taub hau ntawm txoj kev tsheb ciav hlau, uas zoo heev txhim kho nws cov neeg kho tshuab zog kom lub neej kev pab cuam ntawm lub tsheb ciav hlau yuav txuas ntxiv mus.
