U71mn thiab U75V yog ob hom hlau feem ntau siv rau kev tsheb ciav hlau, thiab muaj qee qhov sib txawv ntawm lawv.
1. Tshuaj Txhuam Hniav Sib Txawv
Lub ntsiab sib txawv ntawm U71MN thiab U75V yog cov ntsiab lus carbon thiab cov khoom siv ntxiv. U71mn muaj cov ntsiab lus carbon ntawm 0. 71% thiab tau ntxiv manganese, Thaum U75V muaj ntxiv}. 75% thiab tau ntxiv vanadium .
Tshwj xeeb, cov ntsiab lus carbon ntawm U71MN ranges los ntawm {} {}}. 71% {8}}. 8% .
2. Cov Khoom Siv Hluav Taws Xob
Hais txog cov neeg qaug zog tsis kam, kev tshawb fawb tau qhia tias U71MN muaj kev sib tw zoo dua thiab kev qaug zog tsis kam tshaj U75V rail .
Txawm li cas los xij, U75V ua yeeb yam zoo dua nyob rau hauv cov nqe lus ntawm dov hu rau nkees nkees ua rau lub neej pib thiab coj tus nqi loj hlob. Piv txwv li, kev coj tus nqi kev loj hlob ntawm U75v Kev Rail-Kho Kev Rail yog 12.1% qis dua li ntawm U71MN, thiab kev pib pib ua lub neej tau txuas ntxiv los ntawm 31.1.
