Q: FeSi70 vs FeSi65: Qhov twg zoo dua rau qis - silicon steel ntau lawm?
A: FeSi65 zoo dua rau cov hom phiaj Si tsawg heev; FeSi70 muab Si ntau dua rau ib chav tsev, yog li yuav tsum tau muab tshuaj kom zoo.

 

Q: Vim li cas thiaj xaiv FeSi70 ntau dua cov qib silicon hauv tus nqi- cov ntawv thov nkag siab?
A: Tus nqi qis dua, Si txaus rau cov qauv xav tau, txo cov nqi hlau.

 

Q: Kev siv ntawm FeSi70 hauv kev ua steel hlau (piv txwv li, carbon steel deoxidation)?
A: Tshem tawm cov pa oxygen hauv BOF / EAF, kho Si hauv carbon steels.

 

Q: Siv FeSi70 hauv qhov chaw tsim khoom hnyav -section cam khwb cia hlau?
A: Inoculation los tiv thaiv txias, txhawb nqa graphite zoo ib yam.

 

Q: Lub luag hauj lwm ntawm FeSi70 nyob rau hauv uas tsis yog -ferrous alloy ntau lawm (xws li, tooj liab alloying)?
A: Ntxiv Si rau Cu alloys rau kev txhim kho fluidity thiab lub zog.
