Kev faib tawm cov ntaub ntawv Rail
Taw qhia rau kev faib cov ntaub ntawv ntawm cov ntaub ntawv ntawm cov ntaub ntawv, koj puas paub lawv yog dab tsi?
1. Tib yam carbon cov qauv hlau
Cov hlau zoo tib yam ntawm cov hlau yog cov hlau tsis muaj roj, cov hlau, carbon, silicon, manganese thiab lwm yam. Nws cov khoom muaj cov khoom muaj zog zoo thiab lub zog dav dav, thiab tsim nyog rau cov kab tsheb ciav hlau dav dav. Nws yog ib qho ntawm cov khoom siv rail rail rail nyob rau tam sim no.
2. Tsawg-Alloy High-Lub Zog Txheej Txheem Hlau
Tsawg-alloy High-zog qauv qauv hlau yog hlau, carbon, silicon, chromium thiab lwm yam. Nws lub zog thiab kev nyuaj yog qhov zoo dua li cov roj carbon zoo tib yam, thiab nws yog qhov tsim nyog rau kev kub ceev thiab cov kab hnyav-thauj khoom hnyav.
3. Hnav-resistant steel
Hnav steel tiv thaiv yog cov tsheb ciav hlau nrog cov siab coj tawm tsam, thiab cov pa roj carbon, pob zeb, chromium, vanadium thiab lwm yam. Nws lub hardness yog siab, uas tuaj yeem ua kom zoo dua kev hnav thiab txuas ntxiv txoj haujlwm lub neej ntawm kev tsheb nqaj hlau.
4. Tshwj xeeb steel rau high-ceev railway
Tshwj xeeb hlau rau kev tsheb ciav hlau siab yog hlau, carbon, silicon, siloob, chromium, vanadium thiab lwm yam. Nws muaj lub zog siab, kev coj zoo, hnav tsis kam, thiab tuaj yeem ua tau raws li cov kev ua haujlwm ntawm cov tsheb ciav hlau ceev.
5. Rail Transit Steel
Rail Transit steel yog ib lub tsheb ciav hlau tsim nyog rau cov kev tsheb ciav hlau Urban Transit. Nws cov khoom siv tseem ceeb yog hlau, carbon, silicon, tshuab dhos, manganese, chromium, vanadium thiab lwm yam. Nws muaj lub zog siab, kev coj zoo, hnav tsis kam, thiab tuaj yeem ntsib cov kev yuav tsum muaj ntawm cov kab hlau hla hauv nroog.
Feem ntau, qhov faib tawm thiab cov yam ntxwv ntawm cov khoom siv rail sib txawv. Nws yog ib qho tseem ceeb heev los xaiv cov kev tsheb nqaj hlau raws li kev siv sib txawv thiab cov kev xav tau.
