Dab tsi yog cov khoom ntawm crane rail khoom? - Kev Paub

Crane railyog siv los nqa cov khoom hnyav, uas muaj peev xwm nqa tau siab. Crane rail tseem hu ua crane rail. Nws qhov siab yog qis thiab nws lub taub hau dav thiab lub duav tuab yog loj. Nws yuav tsum tau kuaj xyuas cov tshuaj muaj pes tsawg leeg thiab lub zog tensile. Nws yog dav siv nyob rau hauv kev tsim cov cranes thiab trolley rails.

Dab tsi yog cov khoom ntawm crane rail khoom?

Crane rail khoom qib muaj xws li cov pa roj carbon tsawg, siab yield zog steel, carbon steel, boron steel, thiab tsawg alloy steel.

Crane rail cov ntaub ntawv yog manganese steel, carbon steel, siab silicon tooj liab, tooj liab rail, silicon rail, thiab hais txog. Txoj kev tsheb ciav hlau yog tsim los ntawm cov hlau, uas tuaj yeem muab faib ua cov manganese zoo tib yam -muaj steel rail, tooj liab- muaj cov pa roj carbon steel rail, siab silicon tooj liab -muaj steel rail, tooj liab rail, manganese rail, silicon rail, thiab lwm yam. Feem ntau cov crane rails yog tsim los ntawm U71. Q235 thiab55Q; Cov tsheb hnyav feem ntau yog ua los ntawm45 MNthiab71mn ua.

Ntawm cov crane rail khoom qib,ua 71mnyog cov khoom siv zoo tshaj plaws. Vim tias ntxiv 2-3% manganese rau hauv cov hlau, cov hlau tsis muaj manganese yog nkig li iav. Txawm li cas los xij, yog tias ntxiv> 13% manganese los ua cov hlau manganese siab, nws yuav dhau los ua ob qho tib si tawv thiab tawv. Yog li ntawd, tib neeg siv cov hlau manganese los ua cov tshuab hnav-tiv taus, txuas hniav, thiab crane rails.
