U45mn thiab u71mn

Lub ntsiab sib txawv ntawm U45mn thiab U71MN Rail cov ntaub ntawv yog raws li hauv qab no:

1.Crent xwm txheej:

U45MN: Hauv cov qauv tam sim no rau cov ntaub ntawv ciav hlau tam sim no, U45mn tau txiav txim siab ib qho kev xaiv qub thiab tsis pom zoo ua kev xaiv tseem ceeb.

U71MN: Nws tau dhau los ua qhov kev xaiv tseem ceeb rau niaj hnub cov ntaub ntawv sib tw, tshwj xeeb tshaj yog nyob rau qhov xwm txheej uas muaj zog thiab kav ntev.

2.Cemical muaj pes tsawg leeg:

U45mn: cov tshuaj lom neeg muaj kuab lom ntawm U45mn tsis muaj tshwj xeeb, tab sis feem ntau cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv tau yog li ntawd ntawm U71MN.

U71mn: nws cov tshuaj lom neeg muaj qhov txwv tsis meej, xws li c cov ntsiab lus ntawm 1.101.40%, thiab cov lus hais txog cov txiv neej. Cov kev txwv no ua kom cov kev coj dawb huv thiab kev ua tau zoo ntawm cov ntsia.

3.Mecharanical Khoom:

U45MN: Cov khoom siv tshuab ntawm U45mn tsis muaj tshwj xeeb hais, tab sis feem ntau hais lus, lawv yuav tsis zoo li U71MN.
U71MN: Lub zog tensile yog tsawg kawg yog 880n / mm2, thiab lub elongation tom qab pob txha me me kuj ua tau raws li qee tus qauv. Cov khoom siv no ua kom muaj kev ntseeg tau thiab kev nyab xeeb ntawm cov ntsia hauv kev siv.

4.Applicable structarios:

U45mn: Nws tsis pom zoo vim tias nws tsis tau raws li cov kev xav tau ntawm cov qauv tshiab thiab kev tsim kho tshiab.
U71MN: Nws yog qhov haum rau kev tsheb ciav hlau hnyav uas yuav tsum muaj lub zog siab thiab lub zog, thiab yog cov khoom siv uas nyiam tshaj plaws hauv kev tsim khoom tshiab hauv niaj hnub no.

Hauv cov ntsiab lus, U71MN cov khoom siv tsheb ciav hlau yog qhov zoo dua rau U45MN hauv cov ntsiab lus tshuaj, yog li nws tau dhau los ua qhov kev xaiv tseem ceeb rau niaj hnub kev rails.
